Evolution: Sexual Arms Races
نویسنده
چکیده
The reproductive interests of males and females usually differ, resulting in sexual conflict. Recent studies in which experimental selection trials were carried out under conditions of either 'high' or 'low' sexual conflict show that conflict can promote speciation and reduce female reproductive success.

Male-female conflict and genitalia: failure to confirm predictions in insects and spiders.
Some recent models suggest a new role for evolutionary arms races between males and females in sexual selection. Female resistance to males is proposed to be driven by the direct advantage to the female of avoiding male-imposed reductions in the number of offspring she can produce, rather than by the indirect advantage of selecting among possible sires for her offspring, as in some traditional ...

predicts that unresolvable sexual arms races may be infrequent, and that it is more usual for one sex or the other to gain an evolutionary advantage, halting antagonistic co-evolution, even though the underlying conflict may not be resolved, or that a balance in 'arms levels' results. Exceptions may be common at the molecular level — for example, involving seminal proteins and receptors — where...
متن کاملModelling the evolution of common cuckoo host-races: speciation or genetic swamping?
Co-evolutionary arms races have provided clear evidence for evolutionary change, especially in host-parasite systems. The evolution of host-specific races in the common cuckoo (Cuculus canorus), however, is also an example where sexual conflict influences the outcome. Cuckoo females benefit from better adaptation to overcome host defences, whereas cuckoo males face a trade-off between the benef...
متن کاملThe direct cost of traumatic secretion transfer in hermaphroditic land snails: individuals stabbed with a love dart decrease lifetime fecundity.
Several taxa of simultaneously hermaphroditic land snails exhibit a conspicuous mating behaviour, the so-called shooting of love darts. During mating, such land snail species transfer a specific secretion by stabbing a mating partner's body with the love dart. It has been shown that sperm donors benefit from this traumatic secretion transfer, because the secretions manipulate the physiology of ...
متن کاملSexual dimorphism and sexual conflict in the diving beetle Agabus uliginosus (L.) (Coleoptera: Dytiscidae)
Sexual conflict can drive intersexual arms races, with female resistance and male persistence traits coevolving antagonistically. Such arms races are well documented in some diving beetles, although how widespread sexual conflict is in this family remains unclear. The European dytiscid Agabus uliginosus has a strikingly dimorphic female; individuals from most regions being smooth and male-like,...
