Effects of structural connectivity on fine scale population genetic structure of muskrat, Ondatra zibethicus

摘要: In heterogeneous landscapes, physical barriers and loss of structural connectivity have been shown to reduce gene flow therefore lead population structuring. this study, we assessed the influence landscape features on genetic structure a semiaquatic species, muskrat. A total 97 muskrats were sampled from three watersheds near Sudbury, Ontario, Canada. We estimated using 11 microsatellite loci identified single cluster no differences found among as result high levels flow. At finer scales, correlation between individual pairwise distances Euclidean distance well different models least cost path (LCP). used range values for types in order build our LCP models. positive relationship when considered roads corridors movements. Open landscapes urban areas seemed restrict but not prevent within study area. Our underlines high-dispersal ability generalist species their use highlights how often animal movements are other species.
