Fig. 4: Effective migration surface is based on 637 samples (i.e., excluding five samples from Colorado) typed at 31 autosomal microsatellites.
From: Contrasting genetic trajectories of endangered and expanding red fox populations in the western U.S
Effective migration surface for red foxes (Vulpes vulpes) in the western contiguous U.S. estimated using EEMS. Cool colors indicate areas with higher migration rates than expected under isolation-by-distance, warm colors indicate lower migration rates than expected, and white areas represent expectations under isolation-by-distance.
