During the first phase of TRaCK research, Brad Pusey was a Senior Research Fellow with the Australian Rivers Institute at Griffith University and a Research Professor with the Centre for Excellence in Natural Resource Management at the University of Western Australia. He is interested in the ways in which the distribution, ecology and evolution of freshwater fish help to inform the way in which tropical rivers function. 

Brad undertook his PhD at the University of Western Australia examining life history and physiological adaptations by fishes to life in acidic temporary wetlands. The majority of his research career has been undertaken in tropical and subtropical regions of Australia, first with the Centre for Catchment and In-Stream Research, then the Centre for Riverine Landscapes and later with the Australian Rivers Institute. 

As part of TRaCK’s first phase of research and the synthesis and adoption year, Brad led or co-led several projects associated with environmental flow management, ecohydrological classification of Australia’s natural flow regimes, flow- ecology relationships and the structure of aquatic food webs in tropical Australian rivers. In addition to studies on biogeography, phylogeography and evolution of northern freshwater fish, Brad was the editor of Aquatic Biodiversity of the wet-dry tropics of northern Australia: patterns, impacts and future, co-author of Freshwater Fishes of north-eastern Australia (2004, CSIRO Publishing) and co-author of over 120 scientific papers, book chapters, conference proceedings and reports.


Phase 1 Projects

Outcomes This research has enabled the important findings of other TRaCK research projects in catchments such as the Daly, Fitzroy and Mitchell Rivers to be transferred and applied with confidence, to other catchments in north Australia. For Government natural resource managers the findings from this research has greatly improved the understanding of how remotely sensed data on the environmental attributes of catchments can be used to define water flows. By inferring the water flow characteristics of rivers, where actual flow data would be otherwise unavailable or limited, water planners are better placed to determine environmental water requirements and manage water allocation across Australia in an ecologically sustainable way. An improved understanding of the relationships between hydrology, environmental characteristics and ecology has also assisted in predicting how water flows respond to global climate change.
