Anne Duputié | MEE 2013 | Modelling range shifts in dynamic environments – How can evolution enter the stage?

•

loicdiato

The document summarizes Anne Duputié's presentation on models in evolutionary ecology. It discusses several existing conceptual models for how species respond to environmental changes through migration or adaptation. It then presents a model developed by Duputié et al. that examines how genetic correlations between traits can impact a species' ability to shift its range in response to a changing environment. The model incorporates factors like genetic variance, an environmental gradient, migration rates, and spatial selection pressures.

Anne Duputié – Models in Evolutionary Ecology – May 23rd, 2013 Perspectives Selection gradients vary over space/time  weak response to climatic change? Can the evolution of phenology mitigate projections of range shifts in temperate trees? Optimal reaction norm Simulated fitness, t=later
