The Seminar: In mammals, including humans, there are two types of sleep. The function of the brain activity underlying these states, called rapid eye movement (REM) sleep and non-REM sleep, is an unresolved question in biology. Natural interspecific variation in sleep can constitute a powerful resource to identify the significance of these states. Notably, the study of birds, as the only animals outside of mammals to engage in REM and non-REM sleep, may provide unique insight into the evolution and function of these states by revealing overriding patterns common to both lineages. Such value is particularly salient because the similarity in sleep between mammals and birds appears to have arisen independently through convergent evolution. Here, I highlight three examples for the unique contribution of avian sleep towards our understanding of REM and non-REM sleep in mammals. By doing so, I emphasise that comparisons of sleeping mammals and birds can reveal general aspects of sleep that might not be evident using a strictly mammalian-based research approach.
The Speaker: John completed his PhD at the Max Planck Institute for Ornithology, Seewiesen, Germany, on the evolution and regulation of avian sleep. In 2011, he was awarded a University Postdoctoral Research Fellowship at the University of Western Australia. His research interests focus on the ecology and evolution of sleep, trade-offs between sleep and vigilance, the co-evolution of sleep and brain function, local aspects of sleep homeostasis, the influence of predation risk on sleep in prey, and measuring sleep in the wild.
