Re: Loboda S, and Buddle CM. 2018. Small- to large-scale patterns of ground-dwelling spider (Araneae) diversity across northern Canada. FACETS 3: 880–895. doi:https://doi.org/10.1139/facets-2018-0007
In the originally published version the number of species in Yellowknife and Norman Wells presented in Table 1 did not match the numbers presented in Figure 2. The numbers have been corrected, and all numbers in Table 1 and Figure 2 were reassessed to ensure correctness. Some taxonomic changes have occurred in the last year and corrections to species richness numbers were made accordingly (i.e., in Table 1 corrected observed richness for Banks: 17 and Cambridge Bay: 22; and in Figure 2 corrected observed richness in Moosonee: 98 and Schefferville: 109). The number of mature individuals for Iqaluit, Churchill, Goose Bay, Moosonee, Yellowknife, and Total have been updated (i.e., 383, 2479, 1556, 2225, 2310, and 23010, respectively). These changes did not affect the analyses or conclusions of the manuscript.
The originally published versions of Table 1 and Figure 2 were as follows:

For each site, the total number of species, a pie graph of the diversity by family, and a bar graph with the relative abundance of the two most common families of spiders (Lycosidae and Linyphiidae) are shown. Sites: HA, Hazen Lake, Nunavut; IQ, Iqaluit, Nunavut; CB, Cambridge Bay, Nunavut; BA, Banks Island, Nunavut; CH, Churchill, Manitoba; SC, Schefferville, Quebec; TO, Tombstone mountains, Yukon Territory; KU, Kugluktuk, Nunavut; GB, Goose Bay, Labrador; MO, Moosonee, Ontario; YE, Yellowknife, Northwest Territories; and NW, Norman Wells, Northwest Territories.
