Long-term care (LTC) residents have an increased risk of social isolation and loneliness, and these risks were exacerbated by pandemic policies that restricted visitors. The designated care partner (DCP) program was introduced in some LTC homes to allow designated family members to safely enter the homes and provide support for residents. We undertook a developmental evaluation (DE) to support the development and implementation of the DCP program in three Ontario LTC homes during the COVID-19 pandemic. Data were collected from 65 staff and DCPs through seven iterations of a DE process. Analysis used directed and inductive coding and theming procedures to create a description of the DCP experience. Themes illustrated the barriers and facilitators to the DCP program and revealed a pervasive deficit of care due to inadequate funding, staff shortages, and an acrimonious relationship between staff and family members. Our project demonstrated a need for additional resources and stronger partnerships between staff and family caregivers. - OPEN ACCESSWith growing attention to the ethical and equity implications of Western-based approaches to research, the urgency of decolonizing research has emerged as a critical topic across academic disciplines, including the field of sustainability. The complexity and messiness of this endeavour, however, may translate into uncertainty among researchers about how and where to start. This is partly due to a lack of guidance, training, and accountability mechanisms through Western academic institutions. In this paper, we advance a three-step process that systematically guides critical reflection toward respectful engagement of local and Indigenous communities, as well as other marginalized groups, by drawing on the literature and on learnings from a recent graduate student-led initiative. The process we develop aims to provide a pragmatic starting point for decolonizing research and a counterpoint to conventional modes of research. Such a process will not only foster accountability, respect, and reciprocity but also movement toward locally relevant, context-appropriate, and action-oriented research outcomes. Our three-step process also challenges Western-based and extractive research practices and seeks to facilitate a shift in mindset about the purpose of research and how to approach it.
- OPEN ACCESSIn 2020, the COVID-19 pandemic interrupted all aspects of human activity, including environmental research and monitoring. Despite a lack of laboratory access and other restrictive measures, we adapted an existing community science monitoring program to continue through the summer of 2020. We worked with local community groups to recruit 58 volunteers who collected lake water samples from 60 sites on 16 lakes in south-central Ontario from June to September 2020. We organized drop-off depots and had volunteers freeze samples to monitor nearshore nutrients (phosphorus and nitrogen) and chlorophyll-a. A survey was distributed to volunteers to analyze lake-front property owners’ activities during the pandemic. We found spatial patterns in nearshore water quality across the lakes, with sub-watershed development being a significant predictor of nutrients and chlorophyll-a. Additionally, pre-pandemic (2019) and pandemic (2020 and 2021) nutrient concentrations were compared, but there was no clear impact of the pandemic on nearshore nutrient concentrations, despite changes in lake-front property owners activities. Overall, this study demonstrated the ability of community science to provide water quality data on a large spatial scale despite a major societal disruption, providing insight into regional nutrient trends during the first year of the pandemic.

When researchers are sufficiently resourced to conduct research and communicate their findings, the knowledge produced can benefit the environment and society through policy. However, interference with the research process and its subsequent knowledge mobilization (“interference in science”) has been observed in several countries, particularly for environmental researchers. Using a mixed-methods approach, we surveyed environmental researchers in Canada (n = 741) to investigate the perceived prevalence, source, and effects of interference and considered whether these perceptions differ by region, career stage, research area, and membership in any scientific society. Although over half of researchers were not restricted from speaking to the media (54%), and most had never been asked to make “undue modifications” to their work (84%), the vast majority (92%) reported at least some degree of interference in their work during their careers. Consequences of interference were more prevalent among early-career researchers and included negative impacts on job satisfaction, mental health, and undue modification to work leading to inaccurate or incomplete science communication. Although environmental researchers in Canada deem themselves overall better able to conduct and communicate their work than under previous federal governments, reports of ongoing political interference remain concerning. We recommend increased support for researchers and further investigations into interference. - OPEN ACCESSResearchers in the environmental studies and sciences play a critical role in influencing real-world decision-making and policies. However, interference during research and sharing of results has been documented in Canada and around the world. Further, research has shown that workers from marginalized social identitie(s) experience discrimination in the workplace. Whether interference in research is related to social identity has never been examined. Using a mixed-methods design, we surveyed 741 environmental researchers in Canada to understand the relationship between social identity (gender, disability status, 2SLGBTQI+ status, race, and perception of racial identity) and reported experiences of interference. Results found that researchers with marginalized identities experienced worse outcomes across 11 of the 25 quantitative measures. For example, most marginalized groups experienced significantly greater fear of misrepresentation by media and (or) fear of negative career consequences due to public commentary, and racialized and disabled persons reported greater external interference in their work (e.g., from management and workplace policy). Given these findings, we express concern that the experience of interference in research can (1) threaten the personal well-being of marginalized researchers, (2) limit the representativeness of information disseminated, thererby impacting environmental decision-making and policy, and (3) contribute to inequities in representativeness of marginalized researchers in environmental sciences in Canada.

The COVID-19 pandemic has amplified concerns about food insecurity, prompting its investigation. An online pilot survey anonymously gathered responses from a non-probabilistic sample of 2058 Ecuadorian women. The Food and Agriculture Organization's Food Insecurity Experience Scale was used to measure moderate or severe food insecurity (MSFI). Data quality was assessed using the Rasch item response theory model; this is a single-parameter logistic model that considers food insecurity severity as a latent trait. The analysis produced MSFI prevalence rates with 90% confidence level margins of error (90%MoE). The highest MSFI was found in women: lacking resources for personal expenses (29.53%, 90%MoE = 3.21) compared to those who had them (12.47, 90%MoE = 1.40); who live in the Amazon region (21.37, 90%MoE = 4.24) versus those living in Highlands (17.66%, 90%MoE = 1.77) or in Coast (13.44%, 90%MoE = 2.40); with three or more children (20.97%, 90%MoE = 4.71) against those without children (12.63%, 90%MoE = 3.57); who experienced income reduction during confinement (18.31%, 90%MoE = 2) compared to those who did not (15.71%, 90%MoE = 1.85); and who are rural (18.13%, 90%MoE = 2.83) versus urban residents (16.63%, 90%MoE = 1.55). This study highlights that the most vulnerable Ecuadorian women experienced the highest food insecurity levels during lockdown, emphasizing the need to consider the intersection between income and sociodemographic factors and their impact on women's food insecurity in future research and policymaking. - OPEN ACCESS
Can fisheries be “regenerative”? Adapting agroecological concepts for fisheries and the blue economy
Regenerative design, in which agricultural practices are organized to work with nutrient cycles and successional processes, is increasingly being explored in food systems research and practice. In this commentary, I explore whether regenerative design concepts can be adapted to marine contexts, given increased global interest in the potential of marine ecosystems to support sustainable development, i.e., the blue economy. There are numerous fundamental ecological differences between terrestrial and marine ecologies that make it difficult to directly translate regenerative farming's focus on managing the nutrient cycle. However, building on a framework for regenerative food systems that focuses on how production activities are organized rather than the specific practices and technologies in use, I find multiple useful parallels to familiar patterns in the fisheries literature, specifically, fishing down the food web, poverty traps, and portfolio-based fishing. I conclude with a discussion of directions for research on regenerative fisheries and concerns regarding the potential for greenwashing under the banner of a regenerative blue economy. - OPEN ACCESS

Assisted migration is increasingly being considered as a potential climate change adaptation tactic even though it also comes with potential risk to ecosystems and society. When implementing conservation actions that involve risk, it is prudent to have policies and guidelines to ensure that such actions are conducted in ways that conform to regional standards and consider risks. Here, we report on a policy scan focused on assisted migration in the context of climate change adaptation originally as a protected areas tactic only, but then broadened to ecosystems in Canada beyond those boundaries. Policy scans are a useful strategy for understanding the evolving policy and regulatory landscape for a given topic and can guide the development of such policies in other jurisdictions. Our scan focused on Canada, where multi-scalar governance systems exist relevant to biodiversity and environmental management. Our comprehensive policy scan (involving scans of legislation, policies, and guidelines found online and through direct inquiries with government bodies) revealed major gaps in the assisted migration policy landscape with very few provincial/territorial or federal policies in Canada. A more rudimentary scan in the United States revealed a similar pattern. There was evidence that some jurisdictions anticipated need for such policies and even a few examples of very specific policies (e.g., seeds) that had already been developed, but there were not comprehensive policies or frameworks. Governments and other relevant bodies/organizations may wish to consider working collaboratively toward the development of robust, evidence-based policies for assisted migration given that we anticipate this conservation intervention becoming more popular as climate change impacts on ecosystems become more evident and dire. - OPEN ACCESSUndergraduate research experiences (UREs) have long been integrated into the landscape of undergraduate education, and the typical, one-on-one model has been associated with several positive student outcomes. Newer models of URE, aimed at improving scalability and promoting access for larger cohorts of students, have proliferated. However, due to the absence of a systematic classification of the models of UREs, comparisons across model types are limited, particularly in Canada. Therefore, it is unclear if these scalable models have achieved the aim of providing a more accessible, but equally impactful URE. We used principal component analyses of key variables derived from the course syllabi of 76 UREs to generate a typology of curriculum-based biology UREs, categorized into the following: Type A (apprenticeship-style research), Type B (field courses), and Type C (high enrollment, course-based research). Analysis of the course characteristics of these three course types revealed that Type C courses were the best positioned to provide an accessible learning environment and to include students who would otherwise not participate in research. The development of a typology of UREs provides a foundation to extend previous research on undergraduate research courses—which primarily focuses on the apprenticeship model—to include the other course types characterized in this study.

Inclusion has been gaining increased attention in various domains, including education and the workplace, as well as development, governance, urbanization, and innovation. However, in the context of climate change adaptation (CCA), the concept of “inclusiveness” remains comparatively underexplored, with no overarching framework available. This gap is crucial, given the global scope and multifaceted nature of climate change, which demands a comprehensive and inclusive approach. In this article, we address this deficiency by developing a comprehensive conceptualization of inclusive climate change adaptation (ICCA). Grounded in ethical analysis, our framework is presented for discussion and practical testing. We identify nine specific priority areas and propose one to two qualitative indicators for each, resulting in a suite of 15 indicators for the evaluation of ICCA policies. This research not only highlights the urgency of incorporating inclusiveness into CCA, but it also provides a practical framework by which to guide policymakers, practitioners, and researchers in this critical endeavor. By acknowledging and accommodating diverse value systems and considering the entire policy process, from conception to evaluation, we aim to foster a more inclusive and sustainable approach to CCA. - OPEN ACCESSAlberta grizzly bears are classified as a threatened species in the province of Alberta as of 2010, with human-caused mortality and habitat loss a primary threat. The people who live, work, and recreate within bear habitat play a crucial role in their conservation. While the public is often enthusiastic about grizzly bears, and opportunistically report their observations to government staff, these reports are not systematic or rigorously collected and lack key information. As such, we developed GrizzTracker as a community science program. Following several years of successful deployment, we analyzed community scientist data and evaluated the efficacy of the program through an online user survey. We found that the GrizzTracker app was useful as a data collection and public engagement tool, yielding information for applied management, and that community scientists were generally satisfied. We provide considerations for future program development, including considerations for human, social, technological, and financial capital investment related to design, development, and implementation of data collection protocols, the importance of clearly communicating outcomes, and opportunities for educational outreach. While there is continued trepidation by traditionally trained scientists to develop or engage in community science programs, and some noted areas of improvement for our program specifically, we think that GrizzTracker offers a success story in community science.

Climate change is altering marine ecosystems across the globe and is projected to do so for centuries to come. Marine conservation agencies can use short- and long-term projections of species-specific or ecosystem-level climate responses to inform marine conservation planning. Yet, integration of climate change adaptation, mitigation, and resilience into marine conservation planning is limited. We analysed future trajectories of climate change impacts on total consumer biomass and six key physical and biogeochemical drivers across the Northwest Atlantic Ocean to evaluate the consequences for Marine Protected Areas (MPAs) and Other Effective area-based Conservation Measures (OECMs) in Atlantic Canada. We identified climate change hotspots and refugia, where the environmental drivers are projected to change most or remain close to their current state, respectively, by mid- and end-century. We used standardized outputs from the Fisheries and Marine Ecosystem Model Intercomparison Project and the 6th Coupled Model Intercomparison Project. Our analysis revealed that, currently, no existing marine conservation areas in Atlantic Canada overlap with identified climate refugia. Most (75%) established MPAs and more than one-third (39%) of the established OECMs lie within cumulative climate hotspots. Our results provide important long-term context for adaptation and future-proofing spatial marine conservation planning in Canada and the Northwest Atlantic region. - OPEN ACCESSAnthropogenic pressures, including urban and agricultural expansion, can negatively influence a lake's capacity to provide aquatic ecosystem services (ES). However, identifying lakes most at risk of losing their ES (i.e., higher vulnerability) requires integrating information on lake ecological state, global change threats, and ES use. Here, we provide a social–ecological framework that combines these features within a regional context by evaluating the ecological state of 659 lakes across Canada. Using the deviation of impacted lakes from reference ones, we identified much higher total nitrogen and chloride concentrations as the main indicators of an altered lake ecological state in all regions identified. Lake ecological state was mapped using an additive colour model along with regional scores of threat levels and recreational ES use. Urban and agriculturally developed areas were linked to higher lake vulnerability and ES loss. Lakes in Southern Ontario were most concerning, being highly altered, under threat, and heavily used. Lakes near coastal urban centers were altered and used, but less threatened, whereas those in the Prairies were altered and threatened, but less used. Our novel framework provides the first social–ecological geography of Canadian lakes, and is a promising tool to assess lake state and vulnerability at scales relevant for management.
- OPEN ACCESSAssessing cat local abundance provides information on where wandering cat numbers are highest and what habitats or factors are associated with wandering cats. A variety of stakeholders can lead this research and then use the findings to make scientifically informed decisions to guide the physical locations of cat management actions. Here, we document a framework that engages community members, uses minimal equipment (six trail cameras), and provides scientifically derived information for interested parties to inform, direct, or test the effectiveness of cat management practices. Using these methods in Gatineau, Quebec, Canada, we demonstrate how we estimated cat population size and cat local abundances across a variety of co-variates while accounting for non-perfect detection by using 55 trail camera sites and N-mixture models. Urban areas had three-fold higher local wandering cat abundances than parkland areas, and neighbourhoods below the median income had the highest local abundances of wandering cats. We estimated there are between 8905 and 48,419 (mean 21,298) wandering cats in Gatineau, with 18%–73% of those cats being unowned. These findings can be used to identify locations for future cat management. If estimates of cat abundance are repeated, they can assess the effectiveness of management actions.
- OPEN ACCESSLong-term ecological research (LTER) projects are considered valuable training grounds for graduate student researchers, yet student voices are largely absent from discussions of LTER merits in the literature. We aimed to identify benefits and challenges encountered by current and former graduate students in conducting graduate research within LTER projects. To explore graduate student experiences and perspectives, we conducted a survey comprising both closed-ended questions (i.e., multiple choice and Likert scale) and open-ended questions. From the responses, we identified emergent categories related to positive and negative experiences using sentiment analysis. We found agreement with purported benefits in areas including networking and access to established field sites and protocols. However, participants also identified data accessibility, authorship decisions, communication, and interpersonal conflicts as significant sources of challenges. We synthesized survey results with existing literature to provide actionable recommendations for principal investigators in four main areas (data, authorship, communication, and management) through an LTER lens. In addition to providing longitudinal data, LTER projects offer graduate students both physical and methodological infrastructure that can serve as the scaffold for new research questions to be developed. However, the likelihood of success of student research, as well as the success of the students themselves, can be improved when the needs of graduate students are prioritized.

In late 2020, a private volunteer group operating through a Facebook group approached Toronto and Region Conservation Authority (TRCA) with an interest in participating in the Citizen Science Nest Protection and Monitoring Volunteer Program. During the 2021 season, TRCA staff virtually trained volunteers in turtle nest detection, protection, and monitoring due to COVID-19 social constraints, and provided necessary supplies and equipment. In 2021 volunteers and staff detected 181 turtle nests and were able to protect 75 nests with simple predator-exclusion devices, while in 2022, 165 nests were detected, and 155 were protected. The volunteers also collected data, including nesting location, date, and species in addition to the number of successful hatchlings (2021 only). In 2021, the 75 protected nests yielded 81 Midland Painted Turtle and 665 Snapping Turtle hatchlings. Five Midland Painted Turtle’s eggs were also recovered from an injured turtle, and 44 Snapping Turtle eggs were recovered from a partially predated nest, transported to the Ontario Turtle Conservation Centre, incubated, hatched, and overwintered, and then released back into the local wetlands. The partnership with a local community group proved effective, and we would recommend this practice to other conservation organizations interested in turtle nest protection. - OPEN ACCESSMarine debris is ubiquitous across the global ocean and is an increasing threat to human health, economies, habitats, and wildlife. While local to national action plans are important in addressing this issue, they do not necessarily reflect the needs of coastal communities most heavily impacted. Remote island and coastal communities, particularly in Alaska, do not generate the majority of marine debris impacting their ecosystems; however, they are often left with the task of removal and disposal. Thus, the detrimental effects of marine debris are not only an ecological problem but an issue of environmental justice. This project aimed to catalyze the inclusion of place-based knowledge in marine debris solutions for St. Paul Island, a predominantly (>85%) Alaska Native community in the Bering Sea. We interviewed 36 community members during 2017–2020, documenting their observations of marine debris types, amount, distribution, and impacts over recent decades. Participants reported increasing plastic debris since the 1980s, particularly plastic bottles and fishing gear. Nearly 80% expressed concern about impacts to subsistence resources, including entanglement and ingestion. St. Paul Island community members’ experiences highlight that solving marine debris issues requires broader policies and mitigation strategies addressing sources of debris and advancing environmental justice by impact reduction. Furthermore, this case study can serve as an example of how locally relevant action plans can be developed in other coastal communities around the world by including knowledge and concerns of community members, as they are the most heavily and personally impacted by the marine debris on their shorelines.

Poweshiek skipperling (Oarisma poweshiek Parker, 1870) populations have declined precipitously in the past few decades, and their global range is now restricted to two isolated regions, one of which is the managed Manitoba tall grass prairie in Canada. In this paper, we used a decade of survey data from 2010 to 2019 to understand how habitat features, management practices, and extreme weather impact Poweshiek skipperling abundance in Manitoba. The strongest predictor of abundance was the density of black-eyed Susans (Rudbeckia hirta L.), a primary nectar plant for adults. Poweshiek skipperling abundance also had a negative relationship with both the number of years since a burn occurred and the number of years since grazing occurred. Cumulative precipitation during their active period (May–June) had a negative relationship with skipperling abundance, whereas warm early springs and cool temperatures during the active period had positive relationships. These results suggest that management actions that maintain tall grass prairie habitat in an early successional stage (burning and grazing) and maintain important nectar sources benefit this population. In contrast, extreme weather events had varying effects on Poweshiek skipperling abundance. Results from this study inform ongoing management practices in the Manitoba tall grass prairie to support this endangered population. - OPEN ACCESS

Funding is critical in ecology and related fields, as it enables research and sustains livelihoods. However, early-career researchers (ECRs) from diverse backgrounds are disproportionately underrepresented as funding recipients. To help funding programs self-evaluate progress towards increasing equity, diversity, and inclusion (EDI) in their funding opportunities, we introduce the Stage-based Assessments of Grants for EDI (SAGE) Toolkit. Developed using existing literature, semi-structured interviews, and coauthors’ experiences, the toolkit considers how each funding stage (Advertisement, Application, Review, Awarding) interacts with applicants from racialized and other underrepresented backgrounds. The toolkit offers specific criteria and recommendations, with explanations and examples from funding agencies, to support applicants who have been historically marginalized in ecology and are often left out of equitable funding consideration. Changes in funding mechanisms alone will not reverse the marginalization of communities and peoples in the field of ecology, but advancing EDI must include action throughout the grant process. Efforts to increase EDI must be sustained, and the toolkit allows for additional considerations and evolving best practices. With the SAGE Toolkit, efforts to increase EDI can help to transition away from a transactional dynamic between funder and applicant to instead supportive community and collaboration. The SAGE Toolkit is available online at bit.ly/ediSAGEtoolkit. - OPEN ACCESSDespite the challenges posed by climate change and the biodiversity crisis, most academic research continues to stay within academia and the gaps between conservation science, policy, and practice remain intact. We need to improve the exchange of evidence between researchers and conservation practitioners and focus on solutions-oriented, interdisciplinary science and co-developed research. As we continue to break climate records and lose record numbers of species every year, now is the time for academics to think and act beyond their institutions.

There is growing interest among Western-trained scientists in engaging with Indigenous sciences. This interest has arisen in response to social pressures to reckon with the colonial foundations of Western science and decentre Western ways of knowing, as well as recognition of the need to draw upon the gifts of multiple knowledge systems to address today's many complex social and ecological challenges. However, colonial patterns and power relations are often reproduced at the interface between Western and Indigenous sciences, including the reproduction of epistemic Eurocentrism and extractive modes of relationship between settlers and Indigenous Peoples. This paper seeks to support Western-trained scientists to recognize and interrupt these patterns in order to create the conditions for more ethical, respectful, and reciprocal engagements with Indigenous sciences. We also offer a map of the different ways that Western sciences have thus far engaged Indigenous sciences. We particularly highlight the emergent possibilities offered by a reparative approach to engagement that emphasizes the responsibility of Western science to enact material and relational repair for historical and ongoing harm, including by supporting Indigenous self-determination and sovereignty in science and beyond. - OPEN ACCESS

This paper examines fish consumption advisories (FCAs) as a site of transboundary governance in the Upper St Lawrence River with the aim of identifying opportunities for enhanced coordination and power sharing to address environmental injustices. The Upper St Lawrence River is part of the Great Lakes watershed of North America and the traditional territory of multiple Indigenous Nations, as well as the present-day jurisdictions of Ontario (Canada), Quebec (Canada), and New York State (USA). Through an analysis of publicly available information on FCA programs, we examine similarities and differences in these programs across jurisdictions. We find an overall lack of coordination in fish monitoring and differences in consumption advice for a waterway in which fish may easily move between transboundary areas. We offer recommendations for improving FCAs in this transboundary waterway from the lens of environmental justice, focusing on (1) a shared and transparent approach to monitoring contaminant levels and fish species; (2) integration of cultural food practices; (3) enhanced outreach to angler populations; and (4) upholding the self-determination of Indigenous communities. We also underscore that FCAs should not be seen as a permanent solution. Preventing and reducing contaminants, including associated harm reduction in communities affected by FCAs, need to be priorities. - OPEN ACCESS

A laboratory-based study was conducted to investigate the consumption and degradation of expanded polystyrene (EPS) by superworms (darkling beetle larvae, Zophobas morio; heterotypic synonym Zophobas atratus). Superworms fed on one of three diets (wheat bran control, EPS blocks, or EPS S-shaped chips) following a 60-second pretreatment with UV radiation or no UV radiation exposure. Loss-of-mass measurements were conducted every week for 4 weeks. Nutrients (nitrogen and phosphorus) and EPS degradation products in frass were determined as well as the superworm gut microbiome composition. The average loss of mass after 28 days was 34.7% for EPS blocks and 25.6% for S-shaped chips. Small quantities of nitrogen and phosphorus were found in the frass of superworms that fed on the EPS diet, but they were lower than those from wheat bran-fed superworms. Twenty-one EPS degradation products were identified in the frass of superworms on an EPS diet, including short-chain carboxylic acids, polyols, amino acids, metabolites of amino acids, and phosphoric acids. Pseudomonas aeruginosa (polystyrene degrader) and Stenotrophomonas sp. (nitrogen fixer and phosphorus solubilization promoter) were identified from the guts of superworms that fed on an EPS diet. Overall, superworms have the potential to deal with plastic waste degradation problems. - OPEN ACCESSResearch licensing administered by the Nunavut Research Institute (NRI) affords Nunavummiut (people of Nunavut) an opportunity to engage in research. The NRI partnered with researchers at McMaster and Carleton Universities to investigate social sciences research licensed between 2004 and 2019. This partnership aimed to understand the scope of research trends in Nunavut. Thematic content analysis was used to (i) identify research topics in social sciences and Inuit knowledge projects; (ii) determine frequency and diversity of topics according to leadership, location, and timeframe; (iii) develop metrics to improve tracking of research; and (iv) contribute to the development of a Nunavut research portal making NRI research applications and reports public. Social sciences research increased during the 16-year study period. Projects were predominantly led by Canadian academics. The highest intensity of research occurred in Iqaluit, and the lowest intensity in Grise Fiord. Social sciences research was mainly focused on topics related to Inuit culture and knowledge. Social scientists most often conducted research using interviews and shared their work via peer-reviewed journal articles. This project is a starting point in raising awareness about research trends for Nunavummiut. This work aims to contribute to broader efforts in developing Nunavut-specific approaches to achieving Inuit self-determination in research.
- OPEN ACCESSCOVID-19 was a stark reminder that understanding a novel pathogen is essential but insufficient to protect us from disease. Biomedical and technical solutions are necessary, but they do not prevent or resolve misinformation, vaccine hesitancy, or resistance to public health measures, nor are they sufficient to advance the development of more equitable and effective healthcare systems. Responding to crises such as pandemics requires deep collaboration drawing on multiple methodologies and perspectives. Along with the science, it is imperative to understand cultures, values, languages, histories, and other determinants of human behaviour. This policy briefing argues that the humanities—a group of methodologically diverse fields, including interdisciplinary studies that overlap significantly with the social determinants of health—are an underused source of cultural and social insight that is increasingly important and could be better leveraged in such collaboration. Humanities disciplines approach health and illness as part of the human condition. Their historical perspective could be more effectively mobilized to explore the social and cultural context in which science exists and evolves, in turn, helping us understand the forces shaping perceptions, concerns, and assumptions.
- OPEN ACCESSThe COVID-19 pandemic highlighted the importance of gathering restrictions in slowing the spread of communicable disease. Many restrictions on activities were applied without identifying how effective the restrictions might be in curtailing disease spread. We present a model that estimates the probability of contacting an infected individual as a function of prevalence and self-reported or hypothesized activities. The model incorporates an age adjustment factor to account for differences between the age demographics of infected versus activity participants. The age adjustment factor was important to include when the difference in prevalence between age groups was sufficiently large, and prevalence and activity group sizes were moderate. We applied our contact probability model to two scenarios to demonstrate how the model may inform the development of public health measures. Our model presents a method for estimating contact probability that could be adopted by jurisdictions considering facility closures or group size limits, or for individuals evaluating their own behaviours in future outbreaks or pandemics.
- OPEN ACCESSIn recent years, increasing attention has been directed to “natural climate solutions” to mitigate climate change through the protection, restoration, and improved management of carbon-storing ecosystems. In practice, Indigenous Peoples have been implementing natural climate solutions for millennia through land stewardship. As Indigenous nations and communities in Canada reassert stewardship roles through Indigenous Guardians programs, the question arises: what possibilities emerge when natural climate solutions are driven by Guardians, guided by multifaceted community priorities and Indigenous knowledge? This paper responds to this question, drawing upon collaborative research with Wahkohtowin Development, a social enterprise based in Treaty 9 territory (Ontario, Canada), made up of Chapleau Cree First Nation, Missanabie Cree First Nation, and Brunswick House First Nation. We engaged youth Guardians in workshops that generated insights on the role of youth, cross-cultural collaboration, and holistic conceptualizations of climate action rooted in Indigenous ontologies (such as the Cree philosophy of wahkohtowin, embodying kinship and interconnectedness). Our analysis reveals that Indigenous Guardians are well positioned to advance natural climate solutions and to do so in an integrative manner that addresses intersecting challenges—with benefits for communities, ecosystems, climate action, and reconciliation.

International and transnational cooperation is needed to strengthen environmental governance initiatives with advanced technologies. In January 2023, Ontario Tech University hosted a symposium entitled Tech With a Green Governance Conscience: Exploring the Technology–Environmental Policy Nexus. Attendees spanned diverse disciplines, sectors, and countries, bringing unique and diverse perspectives to the technology–environmental policy nexus. Emergent themes arising from the symposium include the role of artificial intelligence in environmental governance, while eliminating the detrimental social impacts associated with these advanced technologies via algorithmic bias, misunderstanding, and unaccountability. The symposium explored the tech–society–ecology interface, such as the authoritarian intensification of digitalized environmental governance, “technocracy”, and the ethical implications of sacrificing democratic legitimacy in the face of imminent environmental destruction. Select participants (i.e., co-authors) at the symposium provided input on a preliminary framework, which led to this perspective article focused on the politics surrounding green governance in the 21st century. We conclude that while emerging technologies are being deployed to address grand environmental challenges such as climate change, biodiversity loss, and resource depletion, the use of these various technologies for progressive environmental policy development and enforcement requires co-productivist approaches to constructive technology assessments and embracing the concept of technologies of humility. This necessitates a space for dialogue, reflection, and deliberation on leading adaptive environmental governance in the face of power and politics, as we interrogate the putative neutrality of advanced technology and techno-solutionism. - OPEN ACCESSExpanding and creating protected area networks has become a central pillar of global conservation planning. In the management and design of protected area networks, we must consider not only the positive aspects of landscape connectivity but also how that connectivity may facilitate the spread of invasive species, a challenge that has become known as the connectivity conundrum. Here, we review key considerations for landscape connectivity planning for protected area networks, focusing on interactions between network connectivity and the management of invasive species. We propose an integrative adaptive management framework for protected area network planning with five main elements, including monitoring, budgeting considerations, risk assessment, inter-organizational coordination, and local engagement. Protected area planners can address the dynamic aspects of the connectivity conundrum through collaborative and integrative adaptive management planning.

Western Canada is increasingly experiencing impactful and complex wildfire seasons. In response, there are urgent calls to implement prescribed and cultural fire as a key solution to this complex challenge. Unfortunately, there has been limited investment in individuals and organizations that can navigate this complexity and work to implement collaborative solutions across physical, cognitive, and social boundaries. In the wildfire context, these boundaries manifest as jurisdictional silos, a lack of respect for certain forms of knowledge, and a disconnect between knowledge and practice. Here, we highlight the important role of “boundary spanners” in building trust, relationships, and capacity to enable collaboration, including through five case studies from western Canada. As individuals and organizations who actively work across and bridge boundaries between diverse actors and knowledge systems, we believe that boundary spanners can play a key role in supporting proactive wildfire management. Boundary spanning activities include: convening workshops, hosting joint training exercises, supporting knowledge exchange and communities of practice, and creating communication tools and resources. These activities can help overcome unevenly valued knowledge, lack of trust, and outdated policies. We need collaborative approaches to implement prescribed and cultural fire, including a strong foundation for the establishment of boundary spanning individuals and organizations. - OPEN ACCESS

Transboundary rural communities in West Africa play an important role in the exchange of goods, mainly food, among countries. The COVID-19 pandemic restricted these activities due to the closure of the borders. Semi-structured interviews were conducted in two regions of Senegal and Burkina Faso to examine the impacts of these restrictions on the pillars (availability, access, utilization, and stability) of food security in rural areas on men and women. The data set included 230 interviews, and they were analyzed through thematic content analysis. The results showed a decrease in agricultural production in all the communities due to mainly lack of labor force, and limited access to inputs, resulting in increased post-harvest losses. The disruption of trade and border and market closures affected rural families engaged in transboundary trade. Farmers experienced a sharp loss of household income leading to debts and decapitalization. Availability and diversity of and access to food was also heavily affected. Food security greatly varied among the communities and between countries. Perceptions also varied between men and women in terms of production, mobility, and food consumption. The restriction measures have triggered a spiral of effects and responses seriously impacting long-term food security in already highly vulnerable countries. - OPEN ACCESS

The strengths of Indigenous Knowledges and need for reconciliation are increasingly recognized within conservation, leading to a rise in collaborative, cross-cultural research initiatives. As both a cultural keystone and important harvest species, moose are of value to both Indigenous and non-Indigenous Peoples, presenting an opportunity to pursue moose monitoring strategies that embrace the strengths of Indigenous and Western knowledges. While various frameworks provide theoretical direction on how to do so, few resources outline how to apply them in practice. Leaning on guidance of the Ethical Space framework, we explored the meaning and application of value-based approaches in the context of moose monitoring in central Ontario through semi-structured interviews with First Nation communities, the Ontario provincial crown government, and academic researchers. Collectively, 20 core values were identified to be important when bringing Indigenous and non-Indigenous partners together, coupled with a range of tangible actions necessary for fostering Ethical Space. Values and actions reflected three main themes: an emphasis on the long term, the importance of building and maintaining relationships, and the ability to evolve and adapt over time. Insights from this research provide tools and guidance for others interested in enacting Ethical Space in the context of cross-cultural wildlife monitoring and research. - OPEN ACCESSContemporaneous reforms to Canada and British Columbia's environmental impact assessment legislation have the potential to advance Access to Environmental Justice. Access to Environmental Justice is the ability of individuals and communities who are disproportionately and negatively impacted by environmental decisions to access legal and regulatory processes and to have their concerns heard and addressed through environmental decision-making and dispute resolution. Access to Environmental Justice connects concepts of environmental justice, public participation, the rule of law, and access to justice to provide a framework for evaluating the implementation of environmental impact assessment laws. We conducted a preliminary analysis of early implementation of legislative reforms in Canada and British Columbia. Our analysis indicates that a number of factors influence who is seeking to access environmental justice through environmental impact assessment, including geography, project type, and the availability of a legislative mechanism that allows anyone to request an assessment. Whether Canada and British Columbia's reforms are advancing Access to Environmental Justice requires continued analysis as projects continue to be assessed under the new laws.
- OPEN ACCESSMarine protected areas (MPAs) are critical in safeguarding biodiversity and ecosystem functions under climate change. The long-term effectiveness of these static conservation measures will depend on how well they represent current and future ocean changes. Here, we use the Climate Risk Index for Biodiversity to assess the vulnerability representation of marine ecosystems within the Canadian marine conservation network (CMCN) under two divergent emissions scenarios. We found that MPAs best represent climate vulnerability in Atlantic Canada (85% representativity overall, and 93% in the Gulf of Saint Lawrence under low emissions), followed by the Pacific (78%) and Arctic (63%; lowest in the Eastern Arctic (41% under high emissions) regions). Notably, MPAs with lower climate vulnerability are proportionally overrepresented in the CMCN. Broad-scale geographic targets employed in the Scotian Shelf-Bay of Fundy network planning process achieve over 90% representativity of climate vulnerabilities, underscoring the importance of ensuring habitat representativity and geographic distribution in conservation planning to enhance climate resilience, even if not explicitly prioritized. Moving towards Canada’s target to protect 30% of its waters by 2030, prioritizing representativity and designation of MPAs in currently underrepresented climate-vulnerable regions may be crucial to enhancing the resilience of the CMCN amidst an ever-changing climate.

In this paper, we argue that Indigenous data sovereignty (IDS) is vital for addressing threats to ecosystems, as well as for Indigenous Peoples re-establishing and maintaining sovereignty over their territories. Indigenous knowledge-holders face pressure from non-Indigenous scientists to collaborate to address environmental problems, while the open data movement is pressuring them to make their data public. We examine the role of IDS in the context of cumulative effects and climate change that threaten salmon-bearing ecosystems in British Columbia, guided by content from an online workshop in June 2022 and attended exclusively by a Tier-1 audience (First Nations knowledge-holders and/or technical staff working for Nations). Attention to data is required for fruitful collaborations between Indigenous communities and non-Indigenous researchers to address the impacts of climate change and the cumulative effects affecting salmon-bearing watersheds in BC. In addition, we provide steps that Indigenous governments can take to assert sovereignty over data, recommendations that external researchers can use to ensure they respect IDS, and questions that external researchers and Indigenous partners can discuss to guide decision-making about data management. Finally, we reflect on what we learned during the process of co-creating materials. - OPEN ACCESSIn Canada, recent advances towards reconciliation have introduced new collaborations between Indigenous and non-Indigenous governments, including for species-at-risk recovery planning. During these collaborations, Indigenous Knowledge (IK) is often requested, however, clear expectations of what IK is being sought and how diverse knowledge systems will be woven to produce tangible benefits to species recovery are often limited. Here, we provide a case study of a two-stage process to identify and collect IK components that can aid whudzih (caribou) recovery planning. First, we surveyed non-Indigenous government professionals involved in caribou initiatives to specify what IK would benefit recovery planning. Responses were used to guide the development of semi-structured interview questions. Interviews were conducted with knowledge holders from Lhtako Dene, a Southern Dakelh Nation in British Columbia, Canada with historic socioecological ties to caribou. Responses of government professionals highlighted 24 topics for caribou recovery, and interviews with Lhtako Dene knowledge holders revealed strong linkages between ecological and social information types. In some cases, the IK requested was not available from knowledge holders. Collaborations for caribou recovery would benefit from clarity on expectations and outcomes of IK sharing. We suggest that structured processes that respectfully facilitate IK requests and collection become commonplace in species recovery planning.

To investigate the epidemiological connection between nonalcoholic fatty liver disease (NAFLD) and Helicobacter pylori (H. pylori). 6,478 retired and active workers, aged 22-69 years, were included in the study. Their baseline measures of height, weight, waist measurement, body mass index, blood pressure, fasting blood sugar, plasma lipid, liver function index, glycosylated hemoglobin, abdominal ultrasonography, and findings from the line “13 C urea breath test” H. pylori test were analyzed, and follow-up with consistent baseline methods and criteria was performed annually. Over a 4-year period, the prevalence of NAFLD increased by 16.9%, with 612 (18.7%) of those who tested positive for H. pylori developing NAFLD, whereas 484 (15.1%) of those who did not test positive for H. pylori were later diagnosed with new NAFLD (χ2 = 14.862, P < 0.05). One of the risk factors identified in the univariable Cox regression model for NAFLD was H. pylori (Hazard Ratio = 1.297; 95.0% confidence interval (CI) 1.150,1.485, P < 0.000); however, H. pylori continued to be an independent factor affecting the risk of NAFLD even after accounting for gender, age, and aspects of the metabolic syndrome (Hazard Ratio = 1.240; 95.0% CI 1.077,1.429, P = 0.003). The growth of NAFLD may be correlated with H. pylori infection. - OPEN ACCESSIn Quebec, the Act Respecting Threatened or Vulnerable species (ARTV), adopted in 1989, aims to safeguard Quebec's wild genetic diversity by protecting species at risk. However, since its implementation about 30 years ago, it has been repeatedly pointed out that the application of the Quebec legislative framework for the protection of wildlife species at risk was often slow and inadequate. The aim of this article is therefore to make a series of observations on the limits of current legislation and then propose nine urgent recommendations to improve the effectiveness of conservation efforts for species at risk in Quebec. Our recommendations aim to increase the efficiency and transparency of the designation process, reconsider compensation mechanisms for the loss of critical habitat, and harmonize species status between the federal and provincial levels. We hope that our article will pave the way for a constructive discussion leading to an improved protection of wildlife species in precarious situations and their persistence for future generations. The English version of this article is available in the Supplementary material file.
- OPEN ACCESSLarge amounts of waste paper are generated annually worldwide. Although some of it is recycled, up to 50% is landfilled or incinerated. The remanufacturing of waste paper to produce pencils is proposed as a novel, sustainable business solution. A sustainability analysis of this process was performed to quantify indexes of technical, environmental, economic, and social sustainability. Small-to-medium business models were evaluated, in which 15 000 pencils/shift/day can be produced from 135 kg of waste paper, with a maximum productivity of 64 800 pencils/day. Productivity, operating costs, power consumption, land footprint, machine delivery cost, and number of workers were used to analyze the technical feasibility. The cost-to-profit ratio, cost and profit per pencil, and daily profit were used to evaluate economic sustainability. The amounts of municipal solid waste and recovered paper waste, saved embodied energy, and prevented CO2 emissions were used to analyze environmental sustainability. The number of workers and labor costs were used to evaluate human development and social sustainability. The machines required for the remanufacturing line are considered sufficiently mature, remanufactured pencils are less expensive to produce than wooden pencils, and the proposed process minimizes the amount of waste paper sent to landfills and avoids the use of new wood for producing pencils, thereby satisfying technical, economic, and environmental sustainability, respectively. The final sustainability index of 0.9 is considered very high and sufficient for operating a profitable, sustainable business with a profit of 252–583 USD/day.

Status quo frameworks are highly Eurocentric and narrow in scope protecting; biodiversity conservation in many parts of the world and reflect a kind of dichotomized conservation that has created and perpetuated patterns of poverty, food insecurity, and socio-economic marginalization, particularly among Indigenous Peoples. By dichotomized conservation, we mean an approach to conservation that is not taking into consideration the intrinsic interdependence of environment, people, and all the species. It is the management of conservation of different ecosystems and species separately. This framework is opposed to the Indigenous approach to conservation in which people cannot think about their health and well-being without thinking about the health and well-being of Mother Earth. New conceptualizations of biodiversity are needed that are holistic in nature and confront these historical and systemic patterns of exclusion of Indigenous Peoples. - OPEN ACCESSThe Gulf of Maine in the northwestern Atlantic Ocean is one of the world’s fastest warming marine regions. Changes in ocean conditions are affecting growth, survival, and distribution of American lobster (Homarus americanus), which supports iconic fisheries along the coast of Maine, USA. In this study, we analyzed 15 years of oral records from the Maine Fishermen’s Climate Roundtables to explore fishermen’s observations of and responses to social–ecological changes. Fishermen reported an overall shift in lobster biomass further east and offshore, resulting in strategic expansion of fishing seasons and areas. Biomass shifts were thought to be connected to increases in temperature, decreases in salinity, a shift in ocean currents, and a loss of predator species. Fishing strategies were categorized according to five domains of adaptive capacity, but the majority of fishers’ responses fell into two domains: “access to assets” and “diversity and flexibility”. Strategies within these domains included increased expansion into federal lobster fisheries and extension of fishing seasons. Fishermen highlighted data gaps that need to be addressed to meet the challenges of climate change. Fisheries learning exchanges, such as the Climate Roundtables, create social networks that foster knowledge sharing to support the continued viability of local livelihoods.
- OPEN ACCESSMany of Canada’s waterways are modified by the deepening and straightening of stream channels, converting them into agricultural drains to create arable land. While these agricultural drains support diverse aquatic communities and provide important habitat for species at risk, current policies allow for maintenance activities that threaten the survival and longevity of at-risk fish populations. Using three case studies from Ontario, we highlight current challenges to protecting aquatic species at risk in agricultural drains and potential conservation actions that can be taken to protect and restore aquatic species at risk and their habitat within those drains. Conservation actions may vary from ecological modeling to collaborative development of mitigation techniques, and restoration of naturalized habitat in anticipation of future alterations. We provide nine recommendations (including improved legislation, permitting, mitigation, and compliance) on how to better conserve and protect aquatic species at risk in agricultural drains in the future.

The impacts fishing communities face as a result of declining fisheries productivity and access may largely hinge on measurable attributes of their social resilience. Wild-origin Pacific salmon populations have been in a marked decline since the 1960s, resulting in progressively declining access for many commercial fisheries. More recent acute stressors have caused appreciable tribulation to commercial fishers in British Columbia, raising concern over their capacity to remain viable in the industry, and underscoring the need to examine the fishery under a social resilience framework. Here, we coupled an online survey instrument with in-depth interviews to assess commercial salmon fishers’ social resilience, socioeconomic characteristics, risk perceptions, trust in fishery management, and the relationships between these variables. Our results show that social resilience is low overall, with older, more experienced, and less diversified fishers being particularly vulnerable to declining salmon access. While 73% of fishers reported having plans to adapt to future declines in salmon access, 92% reported feeling that there are barriers impeding their adaptation, and 75% reported having no trust in fisheries management helping them adapt. Fishers’ social resilience was positively correlated with their trust in, and perceived trust from fisheries management. - OPEN ACCESSReintroduction is an important tool in the conservation and recovery of aquatic species at risk. However, components of the reintroduction process such as transportation have the potential to induce physiological stress and the extent to which preparatory techniques can mitigate this stress is poorly understood in small-bodied fishes. To address this concern, we studied the effect of transport on two fitness-related performance measures: maximum metabolic rate and thermal tolerance in redside dace (Clinostomus elongatus), an imperilled small-bodied stream fish native to eastern North America. Prior to transportation, we manipulated the body condition of redside dace over a 12-week period, by providing either low (1% of their total body mass) or high (2% of their total body mass) rations. The goal of this manipulation was to influence body condition, as higher body condition can enhance physiological performance. Subsequently, redside dace were transported for varying durations: 0, 3, and 6 h. Following transportation, we measured maximum metabolic rate (µmol/h) and thermal tolerance (CTmax, °C). Our results indicate that neither transport nor body condition had a significant effect on maximum metabolic rate or thermal tolerance (CTmax). These findings provide preliminary evidence that redside dace can physiologically tolerate transport based on the endpoints measured and this information may possibly be extended to other small-bodied fish, for which information is lacking.

In many regions, a tradeoff exists between draining wetlands to support the expansion of agricultural land, and conserving wetlands to maintain their valuable ecosystem services. Decisions about wetland drainage are often made without identifying the impacts on the services these systems provide. We address this gap through a novel assessment of impacts on ecosystem services via wetland drainage in the Canadian prairie landscape. Draining pothole wetlands has large impacts, but sensitivity varies among the indicators considered. Loss of water storage increased the magnitude of median annual flows, but absolute increases with drainage were higher for larger, less frequent events. Total phosphorus exports increased in concert with streamflow. Our analysis suggested disproportionate riparian habitat losses with the first 30% of wetland area drained. Dabbling ducks and wetland-associated bird abundances respond strongly to the loss of small wetland ponds; abundances were predicted to decrease by half with the loss of only 20%–40% of wetland area. This approach to evaluating changes to key wetland ecosystem services in a large region where wetland drainage is ongoing can be used with an economic valuation of the drainage impacts, which should be weighed against the benefits associated with agricultural expansion. - OPEN ACCESS

Several studies have described interhospital transfer coordination structures in the US but there is a lack of data on Canadian coordination systems. We aimed to develop an inventory of existing interhospital coordinating structures across Canada and to detail how they operate in terms of governance, re-sources, tools, and processes. A cross-sectional survey was designed and ten managers/medical officials from seven coordination structures of interhospital transfers across Canada completed the survey. Findings indicate that coordination systems had similar communication modalities and covered similar services including the provision of medical advice. However, they differed in terms of the profile of staff processing transfers and transportation coordination. Mature structures such as Ontario and Alberta, who manage high annual volumes, distinguish themselves with very clear, standardized, and efficient processes, as well as implemented quality and performance improvement methods including key performance indicators. These results suggest that Canada may benefit from having an inter-provincial community of practice for interhospital transfer coordination structures to promote best practices, identify solutions, and harmonize services and processes. Better harmonization in transfer coordination would improve equity in the access to healthcare services. Future research should focus on the elaboration of evidence-and consensus-based guidelines that apply to the Canadian context. - OPEN ACCESS

Plants make up more than one quarter of all species listed under Canada’s Species at Risk Act, but very few have improved in status over time. Ineffective legal protections, lack of public awareness, difficulties in prioritizing species, and a scarcity of research relevant to the recovery of plant species at risk are some of the many challenges facing effective plant conservation in Canada. We used an online survey to ask 243 people who work in plant conservation or who do research in plant ecology or evolution to assess the state of plant conservation in Canada and to identify the actions needed to improve it. Most respondents agreed that Canada is underperforming or merely average when it comes to conserving plants. Based on their responses, we outline a set of recommendations that could form the basis of a national strategy for plant conservation in Canada. These include greater advocacy for habitat protection, connecting researchers with funding opportunities, supporting graduate students working on research related to plant conservation, increasing public awareness of plants, collaborating with and respecting Indigenous knowledge holders, promoting collaboration between researchers and local conservation groups, and increasing capacity to assess the status of species that are potentially at risk. - OPEN ACCESS

It can be challenging for practitioners to determine reasonable response actions following an environmental spill because there are risks associated with the recovery process, acute constraints on time, and few case studies available from antecedent events. Here, we evaluate environmental risk using a screening level assessment (SLA) and describe risk management actions during the response phase of a train derailment that released 600 tonnes of fly ash into a headwater creek in Banff National Park, Canada. Trace metal concentrations and physico-chemical parameters from downstream of the derailment site were compared to Canadian environmental quality guidelines and upstream reference values. There was a 1–2.2-fold exceedance of sediment quality guidelines (As, Cd, and Se) as well as a 3.6–17.5-fold exceedance of water quality guidelines (Al, Cd, Fe, and turbidity) downstream of the train derailment. Despite uncertainty about site-specific toxicity when using a SLA, we did require the removal of the settled fly ash from the creek based on the multiple exceedances of guidelines, regulatory context, wilderness setting, and potential contribution to cumulative effects downstream. Case studies that evaluate risk and describe risk management actions help practitioners make consistent and efficient decisions during the response phase of a spill. - OPEN ACCESS

The movement ecology of Bull Trout (Salvelinus confluentus) in watersheds at the northern geographic range extent is not well understood. We implanted 54 Bull Trout with acoustic transmitters in the Prairie Creek watershed, Northwest Territories, Canada and tracked fish from July 2011 to October 2012 using 19 stationary hydrophones. Bull Trout movement patterns generally corresponded to two groups, as a result of individual variation within and across seasons. The first group exhibited seasonal variations in movement and habitat use, moving most (range 11.7–115.9 km) and occupying the largest home ranges in summer and autumn, while exhibiting little movement during winter and spring. The second group made negligible movements within seasons and resided in localized areas. Restricted movement in winter resulted in a severe range contraction. The average distance moved within a season was 11.5 km (range 0.3–64.9 km per fish). The unusually high prevalence of stationarity in this watershed suggest fish can complete all life processes (spawning, feeding, and rearing) in short reaches (<10 km) of Prairie Creek and tributaries. We encourage researchers to replicate our work in other northern watersheds to determine if the life history we describe represents a regional divergence from more southerly populations. - OPEN ACCESS

Canada’s provinces and territories govern species at risk across most of Canada, with the federal Species at Risk Act generally covering only aquatic species, migratory birds, and species living on federal land. More than a decade after a 2012 report by the environmental law charity Ecojustice on species at risk protection in Canada, we use the same criteria to evaluate the current state of provincial and territorial species at risk legislation, and we provide updates on changes in each jurisdiction since 2012. These criteria are as follows: whether at-risk species are being identified, whether these species are being protected, whether their habitat is being protected, and whether species recovery plans are being created and implemented. We find that there is considerable variation across jurisdictions, with shortcomings that result in inadequate protections for at-risk species, as well as strong components that should be adopted by all jurisdictions. We recommend seven key areas for improvement: dedicated and harmonized legislation, limited discretionary power, increased embrace of scientific and Indigenous knowledge, appropriate timelines for actions, reasonable exemptions to protections, habitat protection across land ownership types, and transparency throughout the process. We urge policymakers to address current shortcomings as they work toward meeting Canada’s biodiversity conservation commitments. - OPEN ACCESSFarmers globally face significant occupational stressors and are reported to experience high levels of depression, anxiety, burnout, suicide ideation, and suicide. While the impacts of high stress and poor mental health have been well-studied in the general population, and to some extent, in specific occupations, the impacts on farmers are understudied. The objective here was to explore the lived experience of high stress and (or) poor mental health in Canadian farmers, including the perceived impacts. Using a phenomenological approach within a constructivist paradigm, we conducted 75 one-on-one research interviews with farmers and people who work closely with farmers, in Ontario, Canada, between July 2017 and May 2018. We analysed the data via thematic analyses and identified four major themes. Participants described myriad negative impacts of farmers’ high stress and (or) poor mental health: (1) personally, (2) interpersonally, and (3) cognitively, which ultimately negatively impacted them (4) professionally, including consequences for productivity, animals, and farm success. The data described far-reaching, interconnected impacts of high stress and poor mental health on participants, the people and animals in their lives, and most aspects of their farming operations, financial viability, and success. Farmer stress, mental health, and well-being are important considerations in promoting sustainable, successful agriculture.

The Royal Society of Canada Working Group on Health Research System Recovery developed actionable recommendations for organizations to implement to strengthen Canada’s health research system. Recommendations were based on input from participants from G7 countries and Australia and New Zealand. Participants included health research funding agency leaders; research institute leaders; health, public health, and social care policy-makers; researchers; and members of the public. The recommendations were categorized using the World Health Organization’s framework for health research systems and include governance/stewardship: (1) Outline research logistics as part of emergency preparedness to streamline research in future pandemics. (2) Embed equity and inclusion in all research processes. (3) Facilitate streamlined, inclusive, and rigorous processes for grant application preparation and review. (4) Create knowledge mobilization infrastructure to support the generation and use of evidence. (5) Coordinate research efforts across local, provincial, national, and international entities. Financing: (6) Reimagine the funding of health research. Capacity building: (7) Invest in formative training opportunities rooted in equity, diversity, and anti-racism. (8) Support researchers’ career development throughout their career span. (9) Support early career researchers to establish themselves. Producing and using research: (10) Strengthen Indigenous health research and break down systemic barriers to its conduct. (11) Develop mechanisms to produce novel research. (12) Enhance research use across the health research ecosystem. - OPEN ACCESSThe environment is changing under the impact of climate change, but many Ontario land trusts still operate with the goal of maintaining historic patterns of biodiversity. This misalignment of conditions and goals may render the important work of these land trusts less effective. To help improve this situation, we conducted several knowledge translation activities to inform Ontario land trusts about possible climate change adaptation options. Throughout the knowledge translation activities, we collected participants’ comments and examined them with hypothesis and descriptive coding to reveal data about challenges and facilitators, which we grouped into themes with pattern coding. The results helped us identify challenges and facilitators that land trusts experience when participating in climate change knowledge translation and attempting to adapt to climate change. The challenges include a lack of resources, limited technical skills and species knowledge, and competing priorities and perspectives. Facilitators include a general interest in climate change, use of tools for adaptation planning, and resource sharing. To increase climate change adaptability in the Ontario land trust sector, we recommend greater collaboration between land trusts, modest modifications to existing conservation actions, shifting from passive to active conservation, and moving from species-level to community and ecosystem function conservation goals.

There is a global movement to implement a One Health approach across sectors to holistically address emerging issues that have implications for public, animal, and environmental health. The operationalization of a One Health model can support knowledge sharing and build an evidence base for designing research programs and decision-making tools to evaluate and mitigate intersectoral health challenges. In late 2021, the highly pathogenic avian influenza virus (HPAIV) H5N1 2.3.4.4b was detected in eastern Canada, and subsequently spread throughout the flyways of North America. Given the multiyear persistence of the current HPAIV in Europe and the continued detections in North America, Environment and Climate Change Canada and partners recognized the need to prioritize HPAIV-related information needs to inform future decision-making and management. In early 2023, we carried out an expert opinion exercise with partners from across One Health domains and expertise to prioritize information needs related to the conservation and management of migratory birds in Canada. The results informed on-the-ground programming for migratory bird activities in 2023 and onwards. The process illustrates how a One Health lens can be applied with a conservation focal point, using dedicated facilitation to synthesize expert opinions across groups with non-overlapping mandates. - OPEN ACCESSConservation easements (CEs) are a private land conservation (PLC) tool, with landowners voluntarily selling property rights to an outside entity (governmental or nongovernmental). Pioneered in the USA, CEs were operationalized in the late 1980s, and by 2001, legislation had swept across Canada. I asked how did subnational Canadian CE policy develop? I analyzed Hansard records and interviewed government officials, finding coercion from the Federal government and environmental nongovernmental organizations (eNGOs), with transfer being ideologically, geographically, and temporally uneven. CE legislation reveals a fundamental shift in how subnational governments were trying to enhance biodiversity conservation, specifically by legitimizing PLC and non-state partners. Interestingly, this study both confirms, and pushes back against, previous Canadian policy transfer studies. I found a lack of formal subnational policy networks and an increased role of subnational policy innovators unlike previous studies, while the substantial U.S. influence align with older policy cases. ENGOs were the most active proponents to push for CE legislation, not policymakers or foreign states. Ultimately, Canadian federalism creates unique subnational policy arenas that require further study to understand the movement of conservation policy, especially with the crises of biodiversity and climate.
- OPEN ACCESSThe generational knowledge of weather and climate is a foundational component of subsistence for Inuit in the Arctic. This knowledge is now challenged by the reality of anthropogenic climate change at a pace that, for Inuit, is impeding fundamental aspects of life in a single generation. To better understand how climate change moderates relationships between Inuit communities and the ecosystem services they rely on, the literature on how climate change is perceived in the circumpolar Arctic was systematically reviewed. The perspectives of Inuit as described in 75 studies were contrasted with those queried from a series of semi-structured interviews with 16 residents of Iqaluit, Nunavut. Within the literature, the themes most frequently mentioned in remote communities were concerns arising about the environment, community, and health. However, the inverse was true for studies that focused on urban communities. Participants from the semi-structured interviews described how colonialism still shapes knowledge translation, which has lasting effects on Arctic climate literacy for Inuit and non-Inuit. As such, an academic knowledge gap in the colonial context in which climate change operates was identified, which requires a way forward that can lead to improvements in the social context for Inuit.

The international collaboration network Food Systems Innovation to Nurture Equity and Resilience Globally (Food SINERGY) unites food system experts concerned with the confluence of environmental, geopolitical, economic, and public health stressors that weaken food systems and increase inequalities. In March 2023, Food SINERGY participants from universities, research institutes, food policy advocacy groups, Indigenous networks, farmers’ associations, consumer organizations, social enterprises, and non-governmental organizations from around the world met in Mont Orford, Québec, for a forum to revisit food system structures across local-to-global scales and to identify key junctures for transformation. This article summarizes the network's discussions in the context of the existing literature. Key knowledge contributions include the importance of diversification throughout the food system for cultivating resilience; the value of food sovereignty in promoting equity across scales; the reconciliation between food sovereignty and equitable trade; the need for consonance between policy environments at different scales to enable positive societal actions; the pioneering role of food system innovations that challenge conventional political and economic structures, with emphasis on agroecology; and the need for critical self-reflection around knowledge production and knowledge use to better serve equitable food systems. These discussion outcomes provide insights for actors seeking to transform food systems in support of equity and resilience. - OPEN ACCESS

There is not one singular way to weave together Indigenous and Western knowledges; creating meaningful cross-cultural collaborations requires a foundation of relationships rooted in the context of specific people and place. As interest in working across knowledge systems increases, our goal is to provide an example of respectful and appropriate cross-cultural collaboration within environmental practice. We demonstrate our collaborative, mixed-methods approach to developing a community-based wildlife monitoring program with Magnetawan First Nation that prioritizes community knowledge and values. Through community interviews and a youth sharing circle, participants highlighted values (respect, interconnection, reciprocity, collaboration, and relationship) as well as research priorities, providing examples of what each may look like in practice, to inform our monitoring approach. These examples, paired with reflections from the research team, are shared to explore the process of weaving together knowledge and values to co-create a community-based wildlife monitoring program, applying wildlife cameras as much more than simply a tool for data collection. This research provides tangible examples of weaving together knowledges and values in the context of environmental monitoring, helping guide future cross-cultural collaboration to ensure this work is being done in a good way. - OPEN ACCESS

Recreational fisheries involve an intimate connection between people, individual fish, and the environment. Recreational fishers and their health crucially depend on healthy fish and ecosystems. Similarly, fish and ecosystems can be impacted by the activities of people including recreational fishers. Thus, amplified by the global interest in recreational fishing, we posit that recreational fishing is particularly suited as an empirical system to explore a One Health perspective, with a goal of creating pathways to better manage such socio-ecological systems for the benefit of people, fish, and the environment. Although zoonoses are uncommon in fishes, fish can carry pathogens, biotoxins, or contaminants that are harmful to people. When captured and released, fish can experience stress and injuries that may promote pathogen development. Similarly, when humans contribute to environmental degradation, not only are fish impacted but so are the humans that depend on them for nutrition, livelihoods, culture, and well-being. Failure to embrace the One Health perspective for recreational fisheries has the potential to negatively impact the health of fish, fisheries, people, society, and the aquatic environment—especially important since these complex social–ecological systems are undergoing rapid change. - OPEN ACCESSThe bigmouth buffalo (Ictiobus cyprinellus, Valenciennes 1844) is a long-lived freshwater fish native to North America that is listed as a species of special concern in its Saskatchewan-Nelson range. Little is known about their ecology and behavior, especially in the Saskatchewan Qu'Appelle River system where it faces multiple threats such as habitat fragmentation and competition with invasive species. In this study, we used acoustic telemetry to track the movements of 44 bigmouth buffalo throughout the Qu'Appelle River system in 2017–2019, and 2021, to monitor migration patterns from spring to fall and investigate if any of the five dams were impeding their ability to access either breeding or overwintering grounds. We found that bigmouth buffalo demonstrated minimal use of the river during this 4-year study, instead staying within the confines of a single lake year-round. Our results suggest that bigmouth buffalo in the Qu'Appelle River do not exhibit migratory behavior during nonflooding years. Considering their extended lifespan (>125 years), this could be attributed to their potential bet-hedging strategy for spawning primarily during flood years. The results indicate that bigmouth buffalo voluntarily remained within Buffalo Pound Lake throughout the study period. Whether this behavior was natural or was influenced by modifications to the system’s hydrology requires further investigation.

Reported rates of soil organic carbon (SOC) accumulation in wetlands are markedly higher over recent versus longer timescales, caused by SOC losses through decomposition, paleoenvironmental changes, and recent increases in sedimentation or biomass production. Explaining changes in SOC sequestration rates and determining the time horizon over which high rates are sustained are both critical for accurately measuring the potential for wetland conservation as a natural climate solution. Here, we present analyses on a 4-m core from a riverine-influenced marsh in Big Creek watershed, southern Ontario, to track changes in SOC accumulation regimes. Since wetland initiation ∼5700 years ago, mean long-term (pre-industrial) rates of SOC accumulation were 24 g C m−2 year−1, and recent rates up to four times higher. We demonstrate that elevated recent rates of SOC accumulation are largely explained by more labile carbon in surficial soils, and are sustained for less than a century before transitioning to slower burial rates of predominantly recalcitrant organic matter. However, there are exceptions to this trend, such as when labile SOC was buried intermittently during Holocene Lake Erie highstands. Our research underscores the importance of organic matter type and hydroclimatic context in predicting long-term potential for marsh soils to stabilize atmospheric carbon. - OPEN ACCESS

Globally, bats provide critical ecosystem services. Rabies, caused by rabies virus and related lyssaviruses, is one of the most significant zoonoses associated with bats. Bat biologists study bats in the laboratory and the field. To minimize the risk of disease, all bat handlers should be vaccinated against rabies and undergo routine serological testing to measure their rabies virus neutralizing antibody levels. They should use best practices to avoid exposures, such as personal protective equipment, especially gloves appropriate to the size of the bat(s) being handled. Attention to such details will prevent unnecessary exposures and avoid some of the accompanying negative perceptions that endanger bats on a global level. The small body sizes of many bats (<50 g, many <20 g) and small teeth makes their defensive bites easy to overlook. Breaks in the skin, however small, may result in exposure to lyssaviruses in the animals’ saliva. Exposure to blood-feeding bats is less common because these species are geographically restricted to the Neotropics and are the only species whose natural feeding behavior could involve transmission of rabies virus. Understanding viral transmission, preventing exposures, and responding appropriately to bites will minimize the consequences of this deadly zoonosis. - OPEN ACCESSWalleye/ogaa (Sander vitreus (Mitchill)) (hereafter, walleye; ogaa = Ojibwe translation) populations have historically supported important multi-use, harvest-oriented fisheries. Despite intensive management, walleye populations have declined in the midwestern United States raising concerns about the sustainability of the species. Numerous factors have been implicated in walleye population declines, including climate change, habitat loss, invasive species, species-interactions, production overharvest (i.e., harvest consistently exceeding annual production), and changing angler behaviors. These factors have negatively influenced natural recruitment and contributed to depensatory recruitment dynamics. I provide a review and perspective suggesting that the current trajectory of walleye populations is at or nearing an ecological tipping point. Although fish populations are often considered compensatory (i.e., negatively density-dependent), current walleye populations appear prone to depensation (i.e., positive density dependence). My review and perspective suggest that a compensatory management perspective for walleye is misaligned. A change in management towards a depensatory resource focus using ecosystem-based fisheries management and the recognition of walleye fisheries as social–ecological systems is needed for conservation. If compensatory management ensues, walleye persistence will likely be further threatened because many drivers of change are outside of managerial control, and those commonly used within managerial control have seemingly been ineffective for sustaining or rehabilitating naturally reproducing walleye populations.

The Atlantic First Nations Water Authority (AFNWA) is the first Indigenous-owned and operated water and wastewater utility in Canada, providing service to 12 First Nations (at the time of this publication), with a Board of Directors composed of Chiefs and technical and legal experts guided by an Elders Advisory Lodge. The AFNWA is forging a path of self-determination in water service provision through honouring First Nations knowledge and culture and implementing leading-edge western engineering practices through Two-Eyed Seeing. The story of the formation and development of the AFNWA offers examples and experiences that may be useful for engineering and industry specialists working to build relationships and offer services to First Nations and First Nations organizations. Through this article, Elders, AFNWA staff, and engineers and researchers from the Centre for Water Resources studies share their narratives of how Two-Eyed Seeing has manifested in the formation of the first Indigenous water utility in Canada. - OPEN ACCESSCommunication of research related to climate change in a way that is meaningful and respectful to Indigenous Peoples is challenging. While engagement with Indigenous communities is now increasingly incorporated into the expected standard of research processes in academia, early career researchers face challenges such as funding limitations, extensive regulatory processes, and timeframes that exceed the duration of a normal graduate-level degree. To better understand the obstacles that early career researchers are faced with, and subsequently provide some guidance on how these barriers can be mitigated, six interviews with practitioners of knowledge mobilization in the Canadian Arctic were conducted. Participants suggested that, while communicating knowledge purposefully depends largely on the research context and communities involved, researchers are encouraged to be well-informed, resourceful, and flexible in their research approaches. By applying these recommendations outlined by experienced practitioners, and reviewing academic literature, early career researchers can mitigate logistical and cultural barriers and communicate knowledge in a more culturally sensitive manner. More community-based research is needed to continue to enhance the understanding of how to mobilize knowledge on climate change in a meaningful way, to create more informed guidelines and support systems, and to make them widely accessible to researchers at all stages of their careers.
- OPEN ACCESSIn this conceptual paper, we argue that the assumptions behind laboratory and field studies are that chemical and compositional analysis may reveal structures unseen by means of human observation. However, replacing human observation to make it obsolete is not the purpose of science; if something can be seen, but is not measurable, that does not make it irrelevant. Although science is frequently primarily regarded as a quantitative field, we argue that qualitative data inclusion is necessary determine the consequences of research on Indigenous communities. We discuss key points, including historical and anthropocentric views of science, suggesting that Indigenous Science requires greater wisdom-based knowledge in association with traditional ecological knowledge. We introduce a new conceptual model called “Pollen Sovereignty”, a sister to Indigenous food sovereignty, to begin critical discussions around the ethics of field research and the impacts of research on the environment, land management, and Indigenous communities. That is, through simple scientific concepts, critical thought, and logic new conceptual frameworks and avenues of research, Indigenous knowledges cannot merely be coopted and reused, but respected and valued.

Marine conserved areas (MCAs) can provide a range of ecological and socio-economic benefits, including climate change mitigation from the protection and enhancement of natural carbon storage. Canada's MCA network is expanding to encompass 30% of its Exclusive Economic Zone by 2030. At present, the network aims to integrate climate change mitigation by protecting coastal vegetated blue carbon ecosystems (saltmarsh, seagrass, kelp). Here, we argue that incorporating unvegetated seabed sediments could bring similar benefits. Seabed sediments can store and/or accumulate high densities of organic carbon, and due to their large spatial extent, contain carbon stores orders of magnitude larger than coastal vegetated habitats. We estimate that currently designated MCAs encompass only 10.8% of Canada's seabed sediment organic carbon stocks on the continental margin, and only 13.4% of areas with high carbon densities. Proposed MCAs would cover an additional 8.8% and 6.1% of total stocks and high carbon areas, respectively. We identify an additional set of high-priority seabed areas for future research and potential protection, ranking their importance based on carbon stocks, proxies for lability, and ecological/biological significance. The incorporation of seabed sediments into MCA networks could support climate change mitigation by preventing future releases of stored carbon. - OPEN ACCESSSeeking to capitalize on a surge in global demand for critical minerals, the Canadian mining sector claims that regulatory processes like Environmental Assessment (EA) impede and delay mining’s economic benefits. This paper investigates whether regulation has delayed mining projects and how much economic benefit mines have delivered in British Columbia (BC), focusing the mines’ performance post-EA. We audit the 27 mines granted an EA certificate in BC since 1995 and projected to open by 2022, comparing each mine’s forecasted and actual timelines and economic benefits (production, employment, and taxes), and identifying publicly-stated reasons for any mine delays. Seven of the 27 mines opened on time: 13 remain non-operational, and of the 14 mines that have operated, seven were delayed. Regulation was cited as a factor in only three of the 20 delayed projects; economic factors like commodity prices were the most common cause of delay. Lack of data and transparency on economic benefits significantly constrained our benefit audit, but BC mines for which data are available are underperforming across production (−77%), employment (−82%), and tax revenue (−100%). These findings suggest economic underperformance and mine delays post-EA are common, with delays typically resulting from economic factors, not government regulations.

Facing the global biodiversity crisis, conservation practitioners and decision-makers seek to catalyze wildlife recoveries in their region. Here we examined social-ecological attributes related to threatened species recovery in Canada. First, we used a retrospective approach to compare the trajectories of the original species assessed by Canada’s species-at-risk committee and found that only eight of 36 species now have decreased extinction risk relative to the past. There were no significant differences in human or financial capacity provided for recovery across species doing better, the same, or worse; the only significant difference was whether the primary cause of decline was alleviated or not. Second, when looking at species assessed at least twice between 2000 and 2019 we found that only eight of 422 (1.9%) experienced both increasing abundance and decreasing extinction risk. The defining characteristic of successful recoveries was first alleviating the original cause of decline, which was most often accomplished through strong regulatory intervention. Once declines were halted, practical interventions were highly species-specific. It is instructive to learn from conservation successes to scale resources appropriately and our results emphasize the importance of threat-specific intervention as a fundamental precursor to the successful restoration of biodiversity in Canada. - OPEN ACCESS

Indigenous peoples in North America are disproportionately exposed to environmental contaminants and may face elevated health risks related to unique socio-cultural ties to the land. Conventional human health risk assessment (HHRA) methods do not account for these unique contexts. Regulators (i.e., Health Canada, US EPA) have called for the development of more ethical and efficient HHRA approaches, but to our knowledge no such approaches have been designed in consideration of Indigenous community contexts. RISK21 is a new HHRA approach gaining regulatory attention. We present two case studies piloting RISK21’s use in collaboration with three unique communities (Cold Lake First Nations, Chipewyan Prairie First Nation, Apsáalooke/Crow Nation). Our objectives are first, reflect upon the benefits and challenges of using RISK21 in these contexts; second, compare RISK21-based to conventional assessments; and third, ideate adaptations and improvements to the approach. The RISK21-based analyses had similar descriptive results to the original conventional assessments, including when using less information. We found RISK21 useful for rapid chemical assessment and visually representing data from multiple sources. We recommend areas where RISK21 (and other next-generation HHRA approaches) might be improved for Indigenous community contexts, including increasing the community relevance of communication tools and incorporating holistic and non-conventional information. - OPEN ACCESSRegulatory ratchets arise when governance appears to be effective, but actually masks a steady loss of natural capital. This occurs when biases in environmental impact assessment (EIA) systematically underestimate the true impact of large developments, generated by statistical convention fixing α at 0.05 (Type 1 error or false positive rate; i.e., the probability of concluding that a development will have an impact when there is none) while β, the false negative rate (failing to detect a true impact, or Type 2 error), is often fixed at 0.2. This asymmetry (β > α) generates a higher likelihood of mistakenly permitting development than mistakenly preventing it. Beyond statistical bias in EIA, routine environmental regulations are often ineffective due to low compliance, inadequate thresholds, and broad exemptions, which tend to cryptically institutionalize net loss. Measuring bias and inefficiency of environmental regulation is foundational to correcting regulatory ratchets and identifying pathways towards no net loss. Like net loss from major developments, cumulative net loss from inadequate routine environmental protections also needs to be estimated and offset by active habitat restoration; this should be delivered as a core program of resource management agencies, with the goal of fully integrating the mitigation hierarchy into routine natural resource governance.

This candid perspective written by scholars from diverse disciplinary backgrounds is intended to advance conversations about the realities of peer review and its inherent limitations. Trust in a process or institution is built slowly and can be destroyed quickly. Trust in the peer review process for scholarly outputs (i.e., journal articles) is being eroded by high-profile scandals, exaggerated news stories, exposés, corrections, retractions, and anecdotes about poor practices. Diminished trust in the peer review process has real-world consequences and threatens the uptake of critical scientific advances. The literature on “crises of trust” tells us that rebuilding diminished trust takes time and requires frank admission and discussion of problems, creative thinking that addresses rather than dismisses criticisms, and planning and enacting short- and long-term reforms to address the root causes of problems. This article takes steps in this direction by presenting eight peer review reality checks and summarizing efforts to address their weaknesses using a harm reduction approach, though we recognize that reforms take time and some problems may never be fully rectified. While some forms of harm reduction will require structural and procedural changes, we emphasize the vital role that training editors, reviewers, and authors has in harm reduction. Additionally, consumers of science need training about how the peer review process works and how to critically evaluate research findings. No amount of self-policing, transparency, or reform to peer review will eliminate all bad actors, unscrupulous publishers, perverse incentives that reward cutting corners, intentional deception, or bias. However, the scientific community can act to minimize the harms from these activities, while simultaneously (re)building the peer review process. A peer review system is needed, even if it is imperfect. - OPEN ACCESS

Environmental indicators are naturally occurring variables, conditions, and events that are used to assess and monitor environmental conditions and change. Inuit throughout Inuit Nunaat (Inuit circumpolar homelands) observe and experience environmental indicators as they travel year-round for harvesting and other cultural practices. Inuit draw on their observations of current conditions and their knowledge of weather, water, ice, and climate (WWIC) indicators, when seeking to predict and understand conditions that impact safe travel. This scoping review documents the types and diversity of WWIC indicators articulated in peer-reviewed and grey literature as being used by Inuit in Canada, Alaska, and Greenland to assess travel safety. Two reviewers independently screened 512 studies using pre-determined eligibility criteria and 123 studies were included for review. A total of 163 unique WWIC indicators were used across 85 communities in Canada, Alaska, and Greenland. Indicators reflect a broad range of ways that Inuit experience their environment, through sight, feel, and sound. Indicators can be considered as causal, conditional, or predictive (or a combination thereof), where knowledge of the interactions among various indicators is especially important to support safe travel. Identified gaps and future research directions included assessing key indicators to better target development of locally relevant research and information services. - OPEN ACCESS

Advancing equity, diversity, and inclusion (EDI) in scientific fields is an outstanding challenge. While there is growing awareness of barriers and challenges to EDI across science, technology, engineering, and mathematics (STEM), individuals may lack the knowledge and/or skills to effect change. This Perspective article describes two resources we developed: (1) a Teaching Toolkit, entitled “Science is for everyone: Integrating equity, diversity, and inclusion in teaching science and engineering—a toolkit for instructors”, and (2) a Research Pocket Guide, entitled “Striving for inclusive excellence in science and engineering research: a pocket guide”. The Teaching Toolkit offers actions, activities, and tools specifically designed for instructors to implement in STEM courses. The Research Pocket Guide offers a dynamic reference tool that is useful to a broad range of researchers. Both resources are distributed under creative commons license and may be adapted for different institutions and contexts. The Teaching Toolkit and Research Pocket Guide are unique with their combination of colourful graphics and novel collections of actionable steps to engage with EDI concepts both in classrooms and research teams. It is our hope that these resources will catalyze change towards advancing EDI in STEM. - OPEN ACCESS

The objective of the present systematic review was to incorporate previous studies investigating the association of birth order with the risk of systolic and diastolic blood pressure (DBP). We employed random-effects and Bayesian meta-analyses, complemented by subgroup and sensitivity analyses, including funnel plots, Begg's rank correlation test, Egger's linear regression test, Galbraith plots, and leave-one-out meta-analysis. Of the 13 articles analyzed, 92% (12 articles) were published from 2010 onwards. The aggregate sample comprised 466 853 firstborns and 646 786 later-born individuals. Geographically, the studies were primarily conducted in Europe (54%), followed by Asia (23%), and America (23%). The pooled mean difference for systolic blood pressure (SBP) under a random-effects model was 0.28 mm Hg (95% CI: −7.03 to 7.59), and for DBP was 0.33 mm Hg (95% CI: −5.38 to 6.04), neither of which reached statistical significance (SBP: Z = 0.08, P = 0.939; DBP: Z = 0.11, P = 0.910). Sensitivity analyses supported these findings. Bayesian meta-analysis presented a 95% credible interval for SBP and DBP ranging from −7.25 to 7.84 and −5.60 to 6.27, respectively. The investigation found no substantial evidence of a significant difference in SBP and DBP between firstborns and later-born individuals, challenging the hypothesis that birth order significantly impacts blood pressure levels. ID registration number: 567971. - OPEN ACCESSCoastal ecosystems face numerous stressors from anthropogenic activities. Furthermore, local stressors that directly impact ecological processes in one location can scale up to have indirect regional consequences. In the case of dispersing marine invertebrates, human activity may impact dispersal and survival rates, which can then alter connectivity patterns and metapopulation dynamics across the seascape. Here, we developed a framework to model metapopulation persistence of seagrass-associated invertebrates in the Salish Sea, focusing primarily on British Columbia, Canada. We combined a biophysical model of dispersal with metrics of habitat naturalness to model how local human activities that may impact dispersal can alter habitat connectivity patterns and potentially impact regional metapopulation persistence. We found that human activities that potentially impact dispersal can reduce population persistence across a region, although the effect varied based on location, population dynamics, and severity of the impacts modeled. The majority of populations, however, remained persistent, suggesting that there are robust and redundant pathways of dispersal that can maintain population connectivity in the face of local disturbances. This study highlights the importance of understanding human impacts and connectivity together in a regional context which could have implications for future marine spatial planning and the effective management of biodiversity.
- OPEN ACCESSThe North American Waterfowl Management Plan (NAWMP) is an international agreement between the Governments of Canada, the United States, and Mexico to coordinate the conservation and restoration of wetlands, associated uplands, and other key habitats for waterfowl and other bird species. To understand public support of NAWMP goals, we conducted a survey of Canadians (n = 2324) and asked about their willingness to make a one-time donation to NAWMP using the contingent valuation method (CVM). Results demonstrate that almost one-third were willing to donate to NAWMP to protect and conserve bird habitats. Parametric analysis of CVM responses provides a mean one-time donation estimate of roughly $33.00 per person. We found that participation in birdwatching is associated with higher willingness to donate to NAWMP, and that this association is stronger among people who participate in multiple outdoor recreation activities. Financial support is more likely to be captured by a variety of donation mechanisms. Fundraising communications that promote purchase of conservation lands, or conservation on public lands, science, and education/outreach programs are more likely to attract donors than conservation on private lands. These findings provide important insights that can assist conservation groups in Canada and beyond in formulating public engagement strategies to enhance revenues from voluntary donations.

In efforts to contribute towards reconciliation, some researchers have shown increased interest in collaborative work with Indigenous Peoples. However, those in technical fields, such as the natural sciences and engineering, are not traditionally trained in how to carry out Indigenous-driven research. This study learned from the successes and challenges of past technical research collaborations to better understand how these researchers can act as stronger allies. Qualitative interviews were carried out with five members of Indigenous communities and 35 researchers. The results showed diverse experiences and the need for more collaborative frameworks and supportive institutional environments within the natural sciences and engineering. Findings highlighted the wide range of issues to be considered in such work, grouped into (1) assessing personal preparation and mindset; (2) building and maintaining relationships; (3) community-aligned benefit; (4) practical and financial considerations; and (5) knowledge sharing and communication. In addition, participants identified institutional-level factors that could help (e.g., mentorship) or hinder (e.g., current recognition structures in many technical fields) efforts to carry out Indigenous-driven technical research. These results may stimulate and contribute to necessary work in the natural sciences and engineering on processes for equitable and thoughtful engagement with members of Indigenous communities to support Indigenous-driven research.
