Linking behavioral ecology with population genetics: insights from Drosophila nigrospiracula.
Although Drosophila species provide important model systems for evolutionary biology, the ecologies and natural histories of most species are insufficiently characterized to permit predictions with respect to issues such as population genetic structure. A notable exception is the group of cactophilic Drosophila endemic to the Sonoran Desert of North America. One of these species, D. nigrospiracula, exhibits no population subdivision anywhere in its range. Here we present evidence suggesting that the timing of mating in relation to dispersal contributes to the panmixia observed in this species.
