| Outline of Final Research Achievements |
What allows cooperators to persist in a population has been a central question in evolutionary ecology, since a game theoretical argument predicts that a population of cooperator can be easily invaded by defectors and may be exploited and eventually become extinct. With collaborators I theoretically and experimentally tested a model that attributes the maintenance of cooperator to spatial structure; an intermediate rate of dispersal could allow cooperators to exploit open patches as temporal refuges where defector populations already collapsed, allowing for coexistence of cooperators and defectors in the whole system.
