Abstract

Due to anthropogenic climate change, there is substantial interest in how temperature variation impacts reproduction and survival in animal populations; however, the underlying mechanisms are often poorly understood. Animals often behaviourally thermoregulate under high ambient temperatures (Tas) to...
