TL;DR: The results confirm the presence of sexually antagonistic selection on postcopulatory interactions that can be reversed by monogamy and demonstrate that the female postmating response, and the male molecules involved in eliciting this response, are shaped by ongoing sexual conflict.

TL;DR: It is suggested that ejaculates of older males are less effective at inducing beneficial responses and that older male flies produce smaller or ill‐composed ejaculates, significantly affecting his reproductive success.

TL;DR: Male reproductive senescence is associated with a decline in functionality of the male accessory gland and the composition of an ejaculate might change with male age as the rate of change was variable for those five genes.

TL;DR: It is shown that learning of host-associated cues in the parasitic wasp Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) shows considerable interpopulation variability, which is at least partly, genetically determined.

TL;DR: It is found that in a setting where males competed directly with a rival male for access to a female and fertilization of her ova polygamous males had superior reproductive success compared to monogamous males, which indicates that in this system, enforced monogamy relaxed selection on traits important in precopulatory rather than postcopulatory competition.
