Immune system activation affects male sexual signal and reproductive potential in crickets
Parasite-mediated sexual selection theory posits that individuals (usually females) choose mates by assessing the expression of costly secondary sexual signals, which provide reliable indications of parasite resistance. If these signals are indeed reliable, then immune-compromised males are predicted to exhibit changes in the sexual signal that are discernable by the female. Moreover, the matin...
متن کاملFood fight: sexual conflict over free amino acids in the nuptial gifts of male decorated crickets.
In decorated crickets, Gryllodes sigillatus, the spermatophore that a male transfers at mating includes a gelatinous spermatophylax that the female consumes, delaying her removal of the sperm-filled ampulla. Male fertilization success increases with the length of time females spend feeding on the spermatophylax, while females may benefit by prematurely discarding the spermatophylaxes of undesir...
متن کاملThe reproductive fitness of the human male gamete
Our understanding of the contribution of the male gamete to reproductive success has a long and intriguing history. It has been known since ancient times that the male provides a vital force that is essential for embryogenesis, however, the functions and relative contributions of the male and female contributions have been debated. For example, Aristotle wrote of the necessity of the male “flui...
متن کاملPlastic responses of male Drosophila melanogaster to the level of sperm competition increase male reproductive fitness.
Evolutionary and plastic responses by males to the level of sperm competition (SC) are reported across widespread taxa, but direct tests of the consequences for male reproductive success in a competitive context are lacking. We varied male perception of SC to examine the effect on male competitive reproductive success and to test whether the outcomes were as predicted by theory. Exposure to riv...
متن کاملNo Intra-Locus Sexual Conflict over Reproductive Fitness or Ageing in Field Crickets
Differences in the ways in which males and females maximize evolutionary fitness can lead to intra-locus sexual conflict in which genes delivering fitness benefits to one sex are costly when expressed in the other. Trade-offs between current reproductive effort and future reproduction and survival are fundamental to the evolutionary biology of ageing. This leads to the prediction that sex diffe...
