Adaptive female choice for middle-aged mates in a lekking sandfly.
Most theoretical models of age-related mate choice predict that females should prefer older males because they have proven survival ability. An alternative view is that older males represent inferior mates because of negative genetic correlations between early and late fitness components, or because older males have traded off longevity against other fitness components, have accumulated deleter...
متن کاملHigh Costs of Female Choice in a Lekking Lizard
Although the cost of mate choice is an essential component of the evolution and maintenance of sexual selection, the energetic cost of female choice has not previously been assessed directly. Here we report that females can incur high energetic costs as a result of discriminating among potential mates. We used heart rate biologging to quantify energetic expenditure in lek-mating female Galápago...
متن کاملPermanent female mimics in a lekking shorebird.
Female mimics are known from many species, but permanent, non-conditional, alternative mating strategies are only known from an isopod, a fish, a lizard and a bird. The single bird example refers to lek-breeding ruffs Philomachus pugnax, a shorebird for which two strategies (independent and satellite) have been known for over 50 years. Ruffs also provided the single case of an animal with two, ...
متن کاملLearning affects mate choice in female fruit flies
Learning in the context of mate choice can influence sexual selection and speciation. Relatively little work, however, has been conducted on the role of learning in the context of mate choice, and this topic has been mostly ignored in insects even though insects have served as a prime model system in research on sexual selection and incipient speciation. Extending recent work indicating apparen...
متن کاملParametric Links for Binary Choice Models: a Fisherian-bayesian Colloquy
The familiar logit and probit models provide convenient settings for many binary response applications, but a larger class of link functions may be occasionally desirable. Two parametric families of link functions are investigated: the Gosset link based on the Student t latent variable model with the degrees of freedom parameter controlling the tail behavior, and the Pregibon link based on the ...
