Survival Rates of the Endangered Indiana Bat, Myotis sodalis

Abstract

Rates of survival of Myotis sodalis are calculated from recaptures of bats marked in cohorts of unknown age. Such data can be misleading, so the proper types ot interpretation are identified. Survival rates are high for 10 years after marking in females and 6 years in males. Females can live as long as 14.8 years and males as long as 13.5 years. Survival of the species is good in undisturbed environments, and endangerment results from loss of habitat.
