Evolution of dispersal: on models, mites and microcosms
Dispersal is one of the core processes governing (meta-)population and (meta-)community dynamics. As a consequence understanding the causes and consequences of dispersal is a central endeavour in ecological and evolutionary research.
Two challenges have often been described for dispersal research: 1) the frequent focus on emigration which leads, for instance, to little knowledge about the evolutionary dynamics of dispersal distances and 2) the rare integration of theory and experiments.
I will address some aspects of both shortcomings by presenting theoretical evidence for the evolution of dispersal distances incorporating the effects of trade-offs, density-dependence and spatially correlated local extinctions. I will link the latter aspect to experimental results for the evolution of dispersal distances in the spider mite Tetranychus urticae.
