Evolutionsbiologie; spieltheoretische Untersuchung zur Evolution von Paarungssystemen
Zusammenfassung der Projektergebnisse
Understanding the evolution of animal mating systems is a major theoretical challenge, and lies at the heart of many topical problems in behavioural ecology. Evolutionary game theory provides a tool for analysing situations where the adaptive value of a phenotypic trait depends on traits expressed by other members of the population, as is frequently the case in the evolution of mating systems. During my fellowship, I have used game theory to study the evolutionary causes and consequences of various aspects of reproductive and social behaviour. In particular, I have characterised conditions for the evolution of (i) male care for offspring; (ii) optimal resource allocation regarding a trade-off between ejaculate production versus gaining matings; (iii) male monogamy; (iv) mate choice for heterozygous mates; and (v) cooperativeness in combination with choosiness.
