Profile Introduction

Animal coloration, biodiversity conservation in the tropics, linking behavioral ecology and conservation biology.


1979 PhD Zoology/Psychology University of St. Andrews, United Kingdom

Research Contribution

I am making a real push to understand the evolution of coloration in mammals. We learn about the colors of animals as children - giant pandas, zebras, and polar bears - but biologists still do not understand why these color patterns evolved. I use simple field experiments, phylogenetic analyses and comparative data to understand the function of coat color in species ranging from zebras to giant anteaters. I expect my research to excite young people about the wonders of nature. I am trying to uncover the best ways of conserving biodiversity and large mammal abundance in the tropics, often focusing on Tanzania where I work for a third of the year. I therefore compare different sorts of legal protection, monitor large mammal populations over time, and work with authorities to find a way to preserve important habitats.

Research Interests

Coloration, Behavior, and Conservation Biology

Evolution of coloration in animals; antipredator strategies in birds and mammals; methods of conserving tropical diversity, linking animal behavior and conservation biology; interspecific predation in mammals.

Teaching Interests

I am interested in giving undergraduate students a comprehensive and broad overview of the fields of conservation biology and of behavioral ecology. In my graduate teaching I explore the intersection of animal behavior and conservation, and try to cover breaking material in the ecology and behavior of predation and prey.
