Dr Andrew Hamer is an Ecologist at ARCUE and has published extensively on frog ecology, including aspects of habitat use, life history and demography, and the impacts of invasive fish and agrochemicals on frog populations. His PhD research focused on the ecology of the endangered Green and Golden Bell Frog Litoria aurea in New South Wales. This research contributed to wetland restoration projects and the management of extant populations. Andrew is currently modelling the determinants of patterns and dynamics in wetland usage by bell frogs.
Andrew has 12 years experience as an environmental consultant and has completed numerous flora and fauna assessments and monitoring projects in New South Wales and Victoria. More recently, he applied information-theoretic methods to improve the ability of a long-term monitoring program to assess the status of a population of the Green and Golden Bell Frog in an urban setting at Sydney Olympic Park. He has also published the results of a monitoring study on the Growling Grass Frog Litoria raniformis in an urban-fringe environment in south-east Melbourne
Andrew’s current research interests include the role of local and landscape factors in determining the distribution of frogs in urban areas. He believes that our understanding of the impacts of urbanisation on frog communities can be improved through studies at multiple spatial scales which integrate aspects of the biotic and abiotic environment.
