Le vendredi 21 décembre - 11h30 Campus Triolet Univ Montpellier: amphi 23.01 - Bât. 23

 (Seminar in English)

Dispersal, the movement of organism from their place of birth to their location of reproduction, is an essential trait in life history and tightly coupled to fitness. A thorough understanding of both the ecological and evolutionary causes and consequences can therefore only be achieved by putting the fitness concept central. I will first outline this theoretical framework and provide insights on how individuals can achieve an optimal dispersal strategy, and why optimal strategies are different among individuals. Next, I will provide a selection of empirical and theoretical examples that demonstrate the consequences of (evolved) changes in dispersal on both metapopulation- and metacommunity dynamics. By closely matching empiricism with theoretical predictions, I will be able to pinpoint why current theory fails in advancing the field of movement ecology towards a predictive discipline in spatial ecology.
