| Summary: | Isolation-by-distance (IBD) is a natural pattern not readily incorporated into theoretical models nor traditional metrics for differentiating populations, although clinal genetic differentiation can be characteristic of many wildlife species. Landscape features can also drive population structure additive to baseline IBD resulting in differentiation through isolation-by-resistance (IBR). We assessed the population genetic structure of boreal caribou across western Canada using non-spatial (STRUCTURE) and spatial (MEMGENE) clustering methods and investigated the relative contribution of IBD and IBR on genetic variation of 1221 boreal caribou multilocus genotypes across western Canada. We further introduced a novel approach to compare the partitioning of individuals into management units (MU) and assessed levels of genetic connectivity under different MU scenarios. STRUCTURE delineated five genetic clusters while MEMGENE identified finer-scale differentiation across the study area. IBD was significant and did ... : Priadka_etal_2018_genotypesGenotypes for 1221 boreal caribou at 9 microsatellite loci. Missing data is indicated by "-99". Coordinates for sampling locations have not been included because boreal caribou are listed as Threatened under Canada's Species At Risk Act.Priadka_etal_2018_Landscape_rastersRaster .asc files of landscape resistance models. Univariate models include resistance costs of 10, 50 and 100. Optimized models for Cluster 1 and Cluster 2 reflect the optimized resistance costs for roads and water bodies (land1), roads and forestry (land2), water bodies and forestry (land3) and roads, water bodies and forestry (land4). Raster cell size is 250m in planar projection. ... |
