Extreme Heat: A new driver of desert mammal assemblages

点击翻译按钮获取中文摘要

Heat waves cause more deaths than any other severe weather event and are becoming longer, more frequent and more intense. Consequently, extreme heat may soon rival predation and rainfall as a major driver of desert mammal assemblages. This project will investigate how heat wave attributes (duration, intensity, frequency), species attributes (physiology, behaviour, plasticity) and landscape features (refuges, fire, grazing) interact and contribute to lethal and sublethal effects of extreme heat on desert mammals. Modelling will predict changes in desert mammal assemblages under different climatic and land management scenarios. Results will inform fire and grazing management, threatened species recovery programs and arid zone restoration.
