 In Florida, the pristine mustached bat became locally extinct at the end of the Pleistocene, what probably resulted from the rise in sea level, the subsequent flooding of caves and loss of roosting sites.The sea level in Florida was as much as 100 m lower in late Pleistocene, as well water tables, and cave systems in Monkey Jungle Hammock, Cutler Hammock and Rock Springs were dry.But during the latest Pleistocene the rising sea level caused flooding of these cave systems and destroyed a hot and humid microclimate of so-called hot caves.
