Genetics of incipient speciation in Drosophila mojavensis. III. Life-history divergence in allopatry and reproductive isolation.
We carried out a three-tiered genetic analysis of egg-to-adult development time and viability in ancestral and derived populations of cactophilic Drosophila mojavensis to test the hypothesis that evolution of these life-history characters has shaped premating reproductive isolation in this species. First, a common garden experiment with 11 populations from Baja California and mainland Mexico an...
متن کاملGenetic Divergence, Reproductive Isolation, and Marine Speciation
In marine species, high dispersal is often associated with only mild genetic differentiation over large spatial scales. Despite this generalization, there are numerous reasons for the accumulation of genetic differences between large, semi-isolated marine populations. A suite of well-known evolutionary mechanisms can operate within and between populations to result in genetic divergence, and th...
متن کاملGenetics of incipient speciation in Drosophila mojavensis. I. Male courtship song, mating success, and genotype x environment interactions.
Few studies have examined genotype by environment (GxE) effects on premating reproductive isolation and associated behaviors, even though such effects may be common when speciation is driven by adaptation to different environments. In this study, mating success and courtship song differences among diverging populations of Drosophila mojavensis were investigated in a two-environment quantitative...
متن کاملSympatry, allopatry and sexual isolation between Drosophila mojavensis and D. arizonae.
Populations of the North American cactophilic fruitfly Drosophila mojavensis and its sibling species D. arizonae exist both in sympatry and in allopatry. Females of D. arizonae, regardless of their population of origin, are effectively completely isolated behaviorally from D. mojavensis males. On the other hand, females of D. mojavensis from the sympatric populations in Sonora, Mexico exhibit s...
