Evolution of dispersal in closed advective environments

摘要: We study a two-species competition model in closed advective environment, where individuals are exposed to unidirectional flow (advection) but no lost through the boundary. The two species have same growth and advection rates different random dispersal rates. linear stability analysis of semi-trivial steady state suggests that, contrast case without advection, slow is generally selected against environments. investigate invasion exponent for various types resource functions, our that there might exist some intermediate rate will be selected. When diffusion small comparable, we determine criteria existence multiplicity singular strategies evolutionarily stable strategies. further show every strategy convergent stable.
