The scent of inbreeding: male sex pheromones betray inbred males
Inbreeding depression results from mating among genetically related individuals and impairs reproductive success. The decrease in male mating success is usually attributed to an impact on multiple fitness-related traits that reduce the general condition of inbred males. Here, we find that the production of the male sex pheromone is reduced significantly by inbreeding in the butterfly Bicyclus a...
متن کاملThe joy of sex pheromones.
Sex pheromones provide an important means of communication to unite individuals for successful reproduction. Although sex pheromones are highly diverse across animals, these signals fulfil common fundamental roles in enabling identification of a mating partner of the opposite sex, the appropriate species and of optimal fecundity. In this review, we synthesize both classic and recent investigati...
متن کاملDo pheromones reveal male immunocompetence?
Pheromones function not only as mate attractors, but they may also relay important information to prospective mates. It has been shown that vertebrates can distinguish, via olfactory mechanisms, major histocompatibility complex types in their prospective mates. However, whether pheromones can transmit information about immunocompetence is unknown. Here, we show that female mealworm beetles (Ten...
متن کاملSex and the single neuron: pheromones excite.
Pheromones are potent chemical signals used by animals across all phyla to control reproductive function and social behavior. Whereas there are few examples of the effects of pheromones on human behavior (fortunately?), in other species, such as laboratory mice, the effects of pheromones have been shown to be dramatic: a female mouse might abort a pregnancy if exposed to pheromones from a male ...
