Longevity, Age-Specific Survival, and Mean Generation Time of <i>Rana muscosa</i>: Implications for Conservation of Possibly the Longest-Lived Ranid Frog.

ABSTRACT: Life history strategies vary widely among species and play a vital role in extinction risk, especially in a rapidly changing environment. For many taxa, information on life history such as longevity, lifespan, and generation time is incomplete. This is especially true for amphibians, which have experienced large-scale declines in recent decades. The mountain yellow-legged frog (Rana muscosa) is a California endemic recognized as a state and federally endangered species. We evaluated a 23-year dataset of six wild R. muscosa populations in southern California. We calculated the average lifespan of individuals in these six populations to be approximately 9.5 years, with a mean generation time of 7.4 years. We did not detect a difference in longevity between sexes or a difference
