Study Organisms: Animals
My main interests are in reproductive strategies: life history traits and sexual behaviour. For example, I study the ways in which individuals in adjust their reproductive strategies to the behaviour and population demography (e.g., sex ratio, density) of conspecifics. Currently, I am investigating this question in guppies in natural populations in Trinidad. I also study the role of frequency dependent selection (rare male advantage and predator search image) in maintaining the extreme, genetically-based variation in the colour patterns of male guppies. Another project looks at the role of sensory bias in mate choice decisions of female guppies.
