Department of Evolution and Ecology, UC Davis, USA

Le vendredi 07 septembre - 11h30 Campus Triolet Univ Montpellier: amphi 23.01 - Bât. 23

 (Seminar in English)
 

 

This talk will highlight two ways that trait variation can impact these dynamics. First, if the trait variation is sufficiently heritable and selection on this variation is sufficiently strong, evolution can occur over eco-logical time scales and, thereby, alter the ecological dynamics.  Second, even if the trait variation isn't heritable, nonlinear relationships between individual traits and the associated demographic rates can re-sult in individuals with more extreme traits having a disproportionately large effect on population-level processes i.e. nonlinear averaging.

I will illustrate these points with the effects of individual variation in infectiousness on disease outbreaks, individual variation in seed dispersal and seed production on rates of spatial spread, and intraspecific trait variation in competing species and their resources on competitive outcomes and, if time permits, coexistence times.
