Polyandrous females discriminate against previous mates.
In most animal species, particularly those in which females engage in polyandry, mate choice is a sequential process in which a female must choose to mate or not to mate with each male encountered. Although a number of theoretical and empirical investigations have examined the effects of sequential mate choice on the operation of sexual selection, how females respond to solicitation by previous...
متن کاملMale scorpionflies assess the amount of rival sperm transferred by females' previous mates.
Theory predicts that when sperm compete numerically, selection will favor males who vary the number of sperm they transfer with the immediate level of sperm competition. In this study, I measured male mating investment in response to both female mating status (virgin vs. mated) and the number of foreign sperm stored by females in a previous mating in the scorpionfly Panorpa cognata. Female sper...
متن کاملDo female leopard geckos (Eublepharis macularius) discriminate between previous mates and novel males?
Females in numerous taxa engage in mating with more than one male within a breeding season, usually to gain direct or indirect benefits from their male partners. Although effort has been directed towards the benefits females derive from multiple mating, we have less information as to decisions females make when choosing to mate with more than one male and if her decision is contingent upon prev...
متن کاملFemales use self-referent cues to avoid mating with previous mates.
Females of many species mate repeatedly throughout their lives, often with many different males (polyandry). Females can secure genetic benefits by maximizing their diversity of mating partners, and might be expected, therefore, to forego matings with previous partners in favour of novel males. Indeed, a female preference for novel mating partners has been shown in several taxa, but the mechani...
متن کاملGreater spear-nosed bats discriminate group mates by vocalizations.
Individuals often benefit from identifying their prospective social partners. Some species that live in stable social groups discriminate between their group mates and others, basing this distinction on calls that differ among individuals. Vocalizations that differ between social groups are much less common, and few studies have demonstrated that animals use group-distinctive calls to identify ...
