Until recently, the little brown bat (Myotis lucifugus) was one of the most common bat species in North America. However, this species currently faces a significant threat from the emerging fungal disease white-nose syndrome (WNS). The aims of this study were to examine the population genetic structure of M. lucifugus hibernating colonies in Pennsylvania (PA) and West Virginia (WV), and to determine whether that population structure may have influenced the pattern of spread of WNS. Samples were obtained from 198 individuals from both uninfected and recently infected colonies located at the crest of the disease front. Both mitochondrial (636 bp …

Species delimitation using mitochondrial sequences aims to identify species as morphological expertise and biodiversity both decline. Species delimitation in animals relies completely or in part on 2 critera: genetic distance and reciprocal monophyly. Using coalescent simulations of populations experiencing continuous and interrupted gene flow we show that these commonly applied criteria incur both high false-positive and high false-negative error rates in species delimitation when dispersal is sex-biased, as it is in most mammals. The combination of distance- and topology-based critera will incur false-positive error rates well above 5% when ancestral effective population sizes are large and when population structure has …
