FEMALE CHOICE VIA INDICATOR TRAITS EASILY EVOLVES IN THE FACE OF RECOMBINATION AND MIGRATION
Proulx, S.R., Evolution, 2001. 55(12):2401-2411
Abstract
How a species responds to spatial subdivision has been a hot topic.
Two approaches have been taken to understand the effects of spatial
subdivision on mating systems: One looks at reinforcement
of partial postzygotic isolation, and the other looks at evolution
of assortative mating when environmental conditions vary spatially.
However, the evolution of assortative mating is not the only way that
spatial subdivision can be enhanced. Female choice of high quality
males can evolve in a subdivided population regardless of the amount
of gene flow, because the same mating strategy is favored in each
population. Likewise, female choice enhances subdivision by increasing
the level of adaptation across space.
