Quantifying exposure of amphibian species to heat waves, cold spells, and droughts

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Globally, amphibians face severe threats, such as climate change and associated extreme events. Our goal was to quantify global amphibian exposure to 3 classes of extreme events: heat waves, cold spells, and droughts. We used the MERRA‐2 extreme climate events data and the standardized precipitation–evapotranspiration index database to ...
