The ecology and evolution of female-specific ornamentation in the dance flies (Diptera: Empidinae)
Elaborate morphological ornaments can evolve if they increase the reproductive success of the bearer during competition for mates. However, ornament evolution is incredibly rare in females, and the type and intensity of selection required to develop female-specific ornamentation is poorly understood. The main goals of my thesis are to clarify the relationship between the type and intensity of s...
متن کاملEffects of forced copulations on female sexual attractiveness in fruit flies
Keywords: courtship Drosophila melanogaster forced copulation fruit fly sexual behaviour sexual conflict Male fruit flies (Drosophila melanogaster) force-copulate with females during the females' short vulnerable period following eclosion. Although sexually immature at that time, the females produce viable progeny from forced copulations. While the females could gain fitness from remating with ...
متن کاملContrasting sexual selection on males and females in a role-reversed swarming dance fly, Rhamphomyia longicauda Loew (Diptera: Empididae).
Although there are several hypotheses for sex-specific ornamentation, few studies have measured selection in both sexes. We compare sexual selection in male and female dance flies, Rhamphomyia longicauda (Diptera: Empididae). Swarming females display size-enhancing abdominal sacs, enlarged wings and decorated tibiae, and compete for nuptial gifts provided by males. Males preferentially approach...
متن کاملRapid evolution of postzygotic reproductive isolation in stalk-eyed flies.
We test the relative rates of evolution of pre- and postzygotic reproductive isolation using eight populations of the sexually dimorphic stalk-eyed flies Cyrtodiopsis dalmanni and C. whitei. Flies from these populations exhibit few morphological differences yet experience strong sexual selection on male eyestalks. To measure reproductive isolation we housed one male and three female flies from ...
