Researcher Summary

Research interests include community ecology of streams (the impact of predation on stream community structure, dispersal mediated patch dynamics in streams, and the impact of predators on grazing and algae in streams via trophic cascades), Aquatic predator-prey interactions (the response of stream invertebrates to chemical cues from fish, the antipredator tactics of mayfly nymphs, and impacts of multiple predators on prey behaviour) and conservation of the New Zealand freshwater fauna (interactions between introduced trout and native fish, the habitats and life cycles of native fish, and restoration of stream habitats).
