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 کاملCryptic female choice of mates in flour beetles (Coleoptera: Tenebrionidae)
Sexual selection drives the evolution of diverse traits that provide an advantage in reproduction. In polyandrous species the traditional premating processes of male-male competition and female choice have as counterparts sperm competition and cryptic female choice (CFC) occurring during and after mating; these processes determine paternity shares of multiple males mated to the same female. I c...
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 کاملThe resident's dilemma: a female choice model for the evolution of alternative mating strategies in lekking male ruffs (Philomachus pugnax)
Previous models for the evolution of alternative male mating behavior have virtually ignored the role of female choice. We present a model in which female choice favors the evolution and maintenance of alternative mating strategies in male ruffi, Philomachus pugnax. Resident male ruffe establish and defend courts on leks against other residents, while non-territorial satellite males move betwee...
