The project intends to improve our understanding of how climate drives shifts in body size and shape in wildlife populations, and the implications of such responses for population viability. Populations of plants and animals are showing a range of responses to recent, rapid shifts in the Earth’s climate. The ecological and evolutionary significance of these responses and the mechanisms that drive them remain largely unknown. Focusing on Australian birds, the project plans to integrate long-term records from citizen science, museum collections and field studies to conduct a comprehensive investigation of the pattern and process of morphological change. Understanding the processes driving change may help in developing strategies to manage our biodiversity as climate changes. Read moreRead less
Getting smaller as temperatures rise? Body size responses of Australian birds to climate change. Many animals appear to be declining in size as climate change occurs, but why this is so is unclear. Using historical records and museum specimens we will determine the factors underlying body size reductions in Australian birds, and especially the role of changing temperature and ecosystem productivity.
