Prof Tim Caro


I am interested in the biological principles underlying the evolution of coloration in animals, and in understanding the ecological circumstances in which different types of external coloration arise in nature. Much of my research involves field work on three continents.

I study the adaptive significance of coloration in animals focusing on two taxonomic groups, mammals and decapods. In mammals I conduct research on the reasons that zebras have stripes, why giant pandas have black and white pelage, and why skunks are so variable in appearance. I also examine the evolutionary drivers of conspicuous coloration across all terrestrial mammals using phylogenetic comparative analyses. In crabs, I study colour polymorphisms in coconut crabs, and protective coloration within and across intertidal crab species.

I am also interested in conservation strategies in tropical ecosystems and I work with government authorities in Tanzania to find practical conservation solutions to exploitation and habitat alteration.

I have a continuing interest in finding links between animal behaviour and conservation biology.
