What are your research interests as they relate to northern Australia?

Jon has over 30 years of experience as an aquatic ecologist working on Queensland’s streams and rivers.  Jon’s areas of interest focus on the ecology of aquatic fauna, particularly macroinvertebrates and fish.  He has a particular interest in the development and application of methods and tools to link environmental stressors to ecological responses, including ecosystem responses to flow regime modifications and environmental variability over both short and long time scales.  For NESP these interests are being applied to research in northern Queensland into environmental flow requirements of Mitchell River ecosystems and impacts of feral pigs on wetland biodiversity.

What do you love about working in northern Australia?

I have always been fascinated by the fauna and fauna of the tropics, which has seemed exotic compared to Brisbane’s. My favourite northern locations are the tropical rivers of Cape York because they are beautiful, poorly understood and to me represent true wilderness.
