Alternative mechanisms of nonindependent mate choice.
Aspects of the environment, including the social environment, can contribute to intrapopulation variation in mating preferences. One example of the effect of social environment on mate preferences is mate choice copying; however, other types of socially influenced (nonindependent) choice might exist. We develop a list of such alternatives based on possible physiological or psychological mechani...
متن کاملMate choice and genetic monogamy in a biparental, colonial fish
In socially monogamous species, in which both sexes provide essential parental care, males as well as females are expected to be choosy. Whereas hundreds of studies have examined monogamy in biparental birds, only several such studies exist in fish. We examined mate choice in the biparental, colonial cichlid fish Neolamprologus caudopunctatus in Lake Tanganyika, Zambia. We genotyped more than 3...
متن کاملConstrained mate choice in social monogamy and the stress of having an unattractive partner.
In socially monogamous animals, mate choice is constrained by the availability of unpaired individuals in the local population. Here, we experimentally investigate the physiological stress endured by a female (the choosy sex) when pairing with a non-preferred social partner. In two experimental contexts, female Gouldian finches (Erythrura gouldiae) socially paired with poor-quality mates had le...
متن کاملMutual Mate Choice Can Drive Costly Signaling Even Under Perfect Monogamy
Models of sexual selection by mate choice have emphasized the evolution of sexually dimorphic costly signals, such as elaborate plumage or courtship display, in the sex exhibiting higher reproductive skew, usually males. Less well explored is the action of mutual mate choice in driving signal evolution in socially monogamous or near-monogamous populations. We present a simulation model of condi...
متن کاملMate choice
If you are interested in the diversity of life, you can not ignore the plethora of striking behaviors and morphologies that have been the handiwork of sexual selection. The peacock’s tail is one emblematic result, but a compendium would also include: the songs of birds, frogs, and crickets, the brilliant colors of fishes and corals, the complex odors of moths and mustelids, and the differences ...
