Temperatures that sterilize males better match global species distributions than lethal temperatures

Prediction of current and future species distributions using thermal limits often relies on lethal temperatures, yet many organisms lose fertility at sublethal temperatures. The authors show that distributions of 43 Drosophila species better match male-sterilizing, than lethal, temperatures.
