guppy2014Social environment and male mate choice in a promiscuous fission-fusion fish society

Jean-Guy J. Godin, Carleton University, Ottawa, Canada

Tuesday 25th November 2014, 11AM, amphitheatre Monge

 

Group living and social behaviour in animals are ubiquitous in nature. Social behaviour (including mating behaviour) is particularly special because conspecifics are selective agents, which can lead to interesting evolutionary dynamics. An individual’s social environment can therefore importantly influence its behaviour and fitness, with implications for social evolution and sexual selection. In this seminar, I will summarize some of our recent research on how males modify their mating tactics in response to variation in the risk of sperm competition, how they use of social information in making mate-choice decisions, and how they can select their social environment so as to enhance their sexual attractiveness and maximize sexual competitiveness. We use the Trinidadian guppy (Poecilia reticulata) as a model study system; this species lives in fission-fusion societies in nature and exhibits mutual mate choice and a promiscuous mating system with high levels of multiple mating and sperm competition.
