Population genetic consequences of geographic disjunction: a prairie plant isolated on Great Lakes alvars.

abstract：:Conspecific brood parasitism allows females to exploit other females' nests and enhance their reproductive output. Here, we test a recent theoretical model of how host females gain inclusive fitness from brood parasitism. High levels of relatedness between host and parasitizer can be maintained either by: (a) kin reco...
