Originally from São Paulo, Brazil, I developed a keen interest in South American reptiles from an early age. I am in the third year of my Ph.D. here at The University of Queensland, and my research is upon the ecology and conservation physiology of the endangered Mary River Turtle (Elusor macrurus), and I aim to reveal aspects of the turtles habitat usage across the various life stages. This project has been carried out in collaboration with a community group located around the Mary River (Tiaro & District Landcare Group). I hope that the results from my Ph.D. will help to conserve this elusive species.

  

 Elusor macrurus is a bimodally respiring freshwater turtle endemic to the Mary River in Queensland. This species is generally found in well-oxygenated pools associated with riffle zones, and its breeding population has been subjected to major impacts over time. It grows up to over 40 cm in carapace length, and is tone of the largest Australian short-necked Chelids. E. macrurus is considered to be in imminent threat of extinction (IUCN, 2008) and is currently listed as endangered. It has a very limited range, being only found within the confines of the Mary River in Queensland, and therefore, changes to that habitat may result in their extinction from the wild. It is therefore, crucial to understand what their habitat requirements are at different life-stages. Surprisingly, there is limited data available on the spatial and temporal habitat exploration of E. macrurus. Thus, the main aim of this research is to investigate the relationship between habitat and nest-site selection of the Mary River turtle (Elusor macrurus).
