My research is concerned with the ways animals respond adaptively to changes in their social, ecological, and physical environment...

Dr Justin Welbergen is an Associate Professor at the Hawkesbury Institute for the Environment (Western Sydney University), and leader of the LAB OF ANIMAL ECOLOGY.
He has strong interests in evolutionary ecology, climate change biology, and conservation. His work and that of his students mainly focuses on birds and bats, but is not limited to these taxonomic groups.
Justin conducted his PhD in Zoology at the University of Cambridge with Professor Nick Davies FRS, and following various prestigious research fellowships in the UK and Australia, he joined the HIE in 2014.
He has published his work in SCIENCE, Nature Climate Change,Current Biology, and Proceedings of the Royal Society, Series B, among others; and he has recently contributed to several high-profile reviews in Annual Reviews in Ecology, Evolution and Systematics, Ecology Letters, and Biological Reviews.

Areas of Research
Evolutionary ecology:
- Movement – proximate causes and ultimate consequences of animal movement across scales
- Animal signals – the functional significance of animal communication
- Social organisation – the ecological and evolutionary interactions within species: social aggregations, mating systems and family dynamics
- Coevolution – the ecological and evolutionary interactions between species: brood parasite-host dynamics and adaptive portfolios
Conservation and climate change:
- Extreme events – the ecological impacts of extreme climate and weather events on biodiversity
- Conservation planning – identifying biodiversity and areas vulnerable to climate change to facilitate adaptation action
- Endangered species biology – ecology and population dynamics of threatened species
- Human-wildlife conflicts – designing evidence-based approaches to mitigating human-wildlife conflicts, particularly in urban environments
