Stage-specific threats reveal the inadequacy of adult-centered conservation
· 2026-09-07 · 原文
In an era of severe global biodiversity threats, understanding the link between species’ traits and their endangerment helps uncover causes of risk and infer threats to understudied species. Most animals have complex life cycles with distinct stages that may face stage-specific threats. Current conservation frameworks rely heavily on adult traits, potentially misjudging extinction risk. Using Chinese anurans as a model, we integrated functional traits from both adult and tadpole stages to examine their association with extinction risk. We found that body size positively correlates with risk in both stages. Microhabitat use is related to extinction risk in tadpoles, but shows no significant link in adults. Adult relative tympanum diameter and head length also correlate with extinction risk.
