Abstract:Human‐facilitated introductions of nonnative populations can lead to secondary contact between allopatric lineages, resulting in lineage homogenisation or the formation of stable hybrid zones maintained by reproductive barriers. We investigated patterns of gene flow between the native Sacramento Valley red fox (Vulpes vulpes patwin) and introduced conspecifics of captive‐bred origin in California's Central Valley. Considering their recent divergence (20–70 kya), we hypothesised that any observed barriers to ge… Show more
