Summary of the project

Northern Australia’s rivers are among the most pristine and productive on earth; but, they face major changes due to human activity including as altered river flows and climate change. Little is known about the key life history and ecological requirements of most of the fish that rely on these river systems. This makes it difficult to assess and manage the risks to fish populations and fisheries from human activities.

Our previous research in northern Australia has identified the importance of maintaining natural rivers to support healthy fish populations.  Emerging evidence suggests that variation in aspects of life history, such as diet, may help fish respond to changing environments.

We have commenced an exciting new ARC Linkage project “Forecasting fish resilience to environmental change in northern Australia”. The project is a partnership between the Northern Territory Government and four Universities: CDU, UWA, Griffith University and the University of Washington (USA) and will investigate how a range of life history traits vary in relation to river flows. This PhD project will form an important component of this larger project and will use stable isotope analysis to examine the variation in the diets of freshwater fish and how these are influenced by river flows. The student will be based at UWA but fieldwork will be undertaken across river systems in the Northern Territory.

Contact the research team leader

Once you have ensured that you meet the eligibility criteria and are ready to discuss a proposal, contact the research team leader to identify a potential supervisor.
Research team leader: Professor Michael Douglas
My research focuses on the ecology and management of tropical ecosystems. This includes the effects of fire, weed and water management on freshwater and savanna ecosystems. I have worked on tropical rivers, floodplains and riparian zones and have studied aquatic invertebrate, fish, and plant communities and the ecosystem processes that connect them, particularly food webs.

This project will be co-supervised by two of Australia's leading fish ecologists: Associate Professor Brad Pusey (Charles Darwin University) and Associate Professor Mark Kennard (Griffith University).
