Sexual selection and immune function in Drosophila melanogaster.
The evolution of immune function depends not only on variation in genes contributing directly to the immune response, but also on genetic variation in other traits indirectly affecting immunocompetence. In particular, sexual selection is predicted to trade-off with immunocompetence because the extra investment of resources needed to increase sexual competitiveness reduces investment in immune f...
متن کاملIncreased sexual activity reduces male immune function in Drosophila melanogaster.
Despite the benefits of resistance, susceptibility to infectious disease is commonplace. Although specific susceptibility may be considered an inevitable consequence of the co-evolutionary arms race between parasite and host, a more general constraint may arise from the cost of an immune response. This "cost" hypothesis predicts a tradeoff between immune defense and other components of fitness....
متن کاملMechanisms underlying sexual selection and sexual conflict in Drosophila melanogaster
The revelation that females o f many taxa mate with multiple males has broadened perspectives in sexual selection to encompass the study o f conflicts of interest between males and females over mating and reproduction. Conflict often exists between the sexes over reproductive decisions such as how often to mate, because the optimum mating rate may often be higher for males than for females. Sel...
متن کاملSexual selection on wing interference patterns in Drosophila melanogaster.
Animals with color vision use color information in intra- and interspecific communication, which in turn may drive the evolution of conspicuous colored body traits via natural and sexual selection. A recent study found that the transparent wings of small flies and wasps in lower-reflectance light environments display vivid and stable structural color patterns, called "wing interference patterns...
متن کاملAdult fitness consequences of sexual selection in Drosophila melanogaster.
Few experiments have demonstrated a genetic correlation between the process of sexual selection and fitness benefits in offspring, either through female choice or male competition. Those that have looked at the relationship between female choice and offspring fitness have focused on juvenile fitness components, rather than fitness at later stages in the life cycle. In addition, many of these st...
