Abstract

Abstract

En 中文
Anurans' sensitivity to hydric stress has driven adaptive changes in multiple traits, potentially displaying geographical clines, as is the case with body size. A longstanding body of research suggests that skin resistance to water loss may also vary geographically in response to water loss. We build upon biophysical first principles to test for the existence of this yet elusive global-level cline in skin resistance to dehydration that alternates with body size across the aridity gradient.
