Ecology and Evolution, Volume 16, Issue 7, July 2026.This study presents the first comprehensive analysis of lifespan and age at sexual maturity in seven common anuran species from Hainan Island's tropical rainforest, filling a critical gap in tropical amphibian ecology. The results reveal significant interspecific variation in lifespan (5 ~ 9 years) and maturity age (3 ~ 5 years), indicating a “slow ...

Behavior and mortality of anurans on roads in the Australian tropics
The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.Roads are a major source of mortality for wildlife, particularly amphibians. Identifying vulnerable species and understanding any behavioral predictors of mortality helps us understand vulnerability to traffic and can inform management strategies. We investigated a 9‐species anuran community in tropical Australia with respect to 3 behavioral responses ...
