Colin R. Townsend obtained his B.Sc. and Ph.D. degrees from the University of Sussex. His previous teaching appointments have been in the Animal Ecology Research Group of Oxford University’s Zoology Department and in the School of Biological Sciences at the University of East Anglia. Currently he is Professor and Head of Department of Zoology at the University of Otago. His teaching interests encompass general ecology, wildlife management and aquatic ecology. He is joint author of the textbook Ecology: Individuals, populations and communities (Begon, Harper and Townsend). In England, Colin’s research concerned the ecology of streams and shallow lakes, with emphasis on the role of predation in structuring aquatic communities. The Taieri River Project now takes up most of his research time. This is aimed at understanding the impact of introduced brown trout on New Zealand’s native biota, the role that land use plays in stream ecology, and the relative importance of biotic factors and physical disturbance in determining the nature of stream communities.Â
