ABSTRACT The kit fox (Vulpes macrotis) appears to be in decline in the northernmost and other peripheral portions of its range, yet its abundance, genetic diversity, and connectivity to core populations are unknown. We used 16 microsatellites and a sex marker to characterize population size and genetic diversity of the northernmost population in southeastern Oregon, USA, which we compared with a core population to the south. We identified 20 individuals from southeastern Oregon, sampled an average of 1.7 times each, resulting in a population size estimate of 28 (95% CI = 20–39) individuals on the study area. We estimated the genetic effective population size of the Oregon population at 14.7 (95% CI = 10.2–22.4) breeding individuals, which was |
