Dots represent individual marten sample locations used in this study. Blue polygons show the extent of subregional study areas, which were determined from broad-scale genetic population clusters (Aylward et al. 2019). Purple polygons show the extent of local study areas, which were determined by finer-scale population genetic clustering (Aylward et al. 2019). The inset shows the location of the study area (dark shading) in relation to the Atlantic coast of the United States. Samples in southern Vermont were not used for model development because of human-mediated gene flow from a reintroduction attempt. However, this location was used in corridor modeling due to the importance of identifying corridors for genetic connectivity to this population.
