Limits to species richness in a continuum of habitat heterogeneity: An ESS approach

摘要: I use a co-evolutionary model to investigate the co-existence of species in ecological and evolutionary time an environment that comprises continuum habitat heterogeneity. The considers ecology evolution communities organized by trade-off foraging costs over environmental continuum. assume foragers optimal patch departure rule for depleting environments, where itself depends on both forager’s phenotype, which is heritable strategy. consider effects three variables co-evolutionarily stable co-existence: (1) travel cost, (2) maintenance replacement (3) range When cost positive, it, as well other two variables, affects richness. Increasing either or results decrease heterogeneity can increase
