Asymmetries in mating preferences between species: female swordtails prefer heterospecific males.
In male swordtails ((Xiphophorus nigrensis)) there are three size classes that derive from allelic variation at the pituitary locus on the Y chromosome. Progeny analysis and preference tests suggest that females prefer to mate with larger males. In the closely related X. pygmaeus, there is no allelic variation at this locus; this species consists of males similar in size only to smaller X. nigr...
متن کاملDo Tetranychus urticae males avoid mating with familiar females?
The two-spotted spider mite, Tetranychus urticae, usually lives in kin groups under common webs. Because only the first mating results in fertilisation in female T. urticae, adult males guard quiescent deutonymph females, those at the stage immediately before maturation, to ensure paternity. Therefore, the cost of precopulatory guarding time seems considerable for males. Moreover, the fitness i...
متن کاملFemale túngara frogs elicit more complex mating signals from males
Sexual selection is responsible for the evolution of costly elaborate male traits. When male displays are dynamic, display strategy is sensitive to contextual cues that alter the relative costs and benefits of producing each signal in a male’s repertoire. Because females often prefer more elaborate signals, males often respond to female presence by elaborating their display. When added elaborat...
متن کاملIndividual differences in aggressiveness of female hamsters: response to intact and castrated males and to females.
The aggressive behaviour of female hamsters was studied while they were housed in large enclosures with males and in brief tests with males or females. Some females are not aggressive with any male, whereas others are very aggressive toward all males in both testing conditions. Females that are not aggressive toward intact males may be very aggressive toward castrated males or females. When the...
متن کاملWhen not to copy: female fruit flies use sophisticated public information to avoid mated males
Semen limitation (lack of semen to fertilize all of a female's eggs) imposes high fitness costs to female partners. Females should therefore avoid mating with semen-limited males. This can be achieved by using public information extracted from watching individual males' previous copulating activities. This adaptive preference should be flexible given that semen limitation is temporary. We first...
