Effect of oceanic straits on gene flow in the recently endangered little brown bat ( Myotis lucifugus ) in maritime Canada: implications for the spread of white-nose syndrome
White-nose syndrome is rapidly spreading in eastern North America, causing mass mortality of hibernating bats. We characterized levels of genetic diversity and population structure of the little brown bat (Myotis lucifugus (Le Conte, 1831)) in eastern Canada to infer the extent to which oceanic stra...

White-nose syndrome is rapidly spreading in eastern North America, causing mass mortality of hibernating bats.
