Our hypotheses were that (1) the emergence of the disease white nose has reduced the abundance of bats in North America at levels similar to those in Europe, where the disease is endemic, a priori, and (2) emerging diseases affect species distribution patterns by causing local extinctions, especially for small colonies.
