Longevity, Age‐Specific Survival, and Mean Generation Time of Rana muscosa: Implications for Conservation of Possibly the Longest‐Lived Ranid Frog

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We examined 22 years of mark and recapture data for an endangered amphibian (Rana muscosa) and estimated longevity, age‐specific survival, and mean generation time. The oldest individual was determined to be at least 21 years old. ABSTRACT Life history strategies vary widely among species and play a vital role in extinction risk, especially in a ...
