Dr Paul Humphries

Dr Paul Humphries' research interests mostly relate to rivers and their ecology. While he has worked mostly on fish-related topics, he also has an interest in macroinvertebrates and macrophytes. Most of his work in the last 20 years has been on the relationship between riverine biota and flow. Since 1996, he has focussed on aspects of the spawning and early life history of freshwater fishes. He has also carried out and collaborated on several projects on the dispersal of the young stages of fish and shrimp in rivers both in Australia and Europe. He is also passionately interested in historical ecology, especially in the Murray-Darling Basin, and is currently collaborating on several palaeoecological and zooarchaeological projects, which aim to look at past faunas and ecosystems, to aid conservation and management of our rivers. He co-edited with Keith Walker, 'Ecology of Australian Freshwater Fishes', published by CSIRO Publishing in 2013.

Paul is the leader of the Fish Ecology Collaborative Research Unit
