Evolutionary Convergence to Ideal Free Dispersal Strategies and Coexistence

EVOLUTIONARY STABILITY OF IDEAL FREE DISPERSAL STRATEGIES: A NONLOCAL DISPERSAL MODEL Dedicated to Herb Freedman on the occasion of his 70th birthday

ABSTRACT. An important question in the study of the evolution of dispersal is what kind of dispersal strategies are evolutionary stable. This work is motivated by recent work of Cosner et al. [9], in which they introduced a class of ideal free dispersal kernels and found conditions suggesting that they determine evolutionarily stable dispersal strategies. The goals of this paper are to introduc...

Clumped Dispersal and Species Coexistence

Turbulent dispersal promotes species coexistence

Several recent advances in coexistence theory emphasize the importance of space and dispersal, but focus on average dispersal rates and require spatial heterogeneity, spatio-temporal variability or dispersal-competition tradeoffs to allow coexistence. We analyse a model with stochastic juvenile dispersal (driven by turbulent flow in the coastal ocean) and show that a low-productivity species ca...

Mixed Dispersal Strategies and Response to Disturbance

Question: How does selection mediated by a spatially spreading disturbance affect individual-level dispersal and population-level spa-

Rough Ideal Convergence

In this paper we extend the notion of rough convergence using the concept of ideals which automatically extends the earlier notions of rough convergence and rough statistical convergence. We define the set of rough ideal limit points and prove several results associated with this set.
