研究领域

We study a range of subjects in sensory and evolutionary ecology, but most notably adaptive coloration and vision. Most of our research covers anti-predator coloration, brood parasitism, and methods to study vision and visual signals. Our work is interdisciplinary, spanning sensory, behavioural, evolutionary biology, and incorporates ideas and methods from experimental psychology and computer vision. We work on various taxonomic groups, including birds, reptiles, crustaceans, insects, and primates. Most of our work has focussed on anti-predator coloration and brood parasitism. These areas have been discussed since Darwin and Wallace, but only recently have we started to understand animal coloration and information use in terms of the appropriate receiver’s perspective, and our aim is to understand these areas in terms of receiver vision. Some of our main aims are to: Understand animal coloration in terms of how the signals are perceived by the relevant receiver(s), and use this to study how visual information guides behaviour. Determine how arms races and coevolution can drive both intra- and interspecific diversity in animal coloration and vision. Understand how the form and diversity of coloration and visual systems results from varied selection pressures, for example from different habitat structures and for both communication and predator avoidance.
