Seasonal changes in humidity level in the tropics impact body color polymorphism and desiccation resistance in Drosophila jambulina-Evidence for melanism-desiccation hypothesis.

Abstract excerpt

Drosophila jambulina exhibits color dimorphism controlled by a single locus but its ecological significance is not clear. Dark and light morphs differ significantly in body melanisation, desiccation resistance, rate of water loss, mating activity and fecundity. Interestingly, this species lacks c...
