Strong population genetic structure and cryptic diversity in the Florida bonneted bat (Eumops floridanus)

Knowledge of the genetic structure and cryptic diversity is essential for the conservation of endangered species. We conducted a genetic survey of the federally endangered Florida bonneted bat ( Eumops floridanus ) sampled from its USA range in southern Florida. Florida bonneted bats are primarily found in four regions separated by approximately 100 to 250 km, including three western natural areas: Babcock Webb WMA (BW), Polk County (PC), and Collier County (CC) and one urban population on the east coast, Miami-Dade County (MD). We used 22 microsatellite loci and cytochrome b sequences to assess the extent of connectivity and levels of genetic diversity. Populations were highly differentiated at microsatellite loci (overall F ST = 0.178) and model-based and ordination analyses showed that MD was the most distinct among pairwise comparisons. Regional populations were small ( N e
