Female ornamentation and male mate choice in dark-eyed juncos
Traits that enhance attractiveness in one sex may or may not influence attractiveness in the other. In the dark-eyed junco, Junco hyemalis, outer tail feathers of males and females are all or partly white and form a sharp contrast with the bird’s mostly grey plumage. The amount of white in these feathers (‘tail white’) is greater in males than in females and, as we report here, is greater in bi...
متن کاملCan non-directional male mating preferences facilitate honest female ornamentation?
Recent studies have demonstrated male mate choice for female ornaments in species without sex-role reversal. Despite these empirical findings, little is known about the adaptive dynamics of female signalling, in particular the evolution of male mating preferences. The evolution of traits that signal mate quality is more complex in females than in males because females usually provide the bulk o...
متن کاملThe Role of Visual Ornamentation in Female Choice of a Multimodal Male Courtship Display
The courtship behavior of male Schizocosa uetzi wolf spiders incorporates both visual and seismic signals into a multimodal display. These two signals have been shown to interact in such a manner that the seismic signal alters a female’s response to the visual signal, leading to a putative increased importance of visual signaling in the presence of a seismic signal. Experiments leading to this ...
متن کاملFemale ornamentation influences male courtship investment in a lizard
*Correspondence: Devi Stuart-Fox, Zoology Department, The University of Melbourne, Building 147, Royal Parade, Parkville, VIC 3010, Australia e-mail: [email protected] Female signals of reproductive status often comprise both distinctive color patches and behaviors but their relative influence on male courtship investment is unclear. We examined the role of female-specific coloration in sign...
متن کاملFemale preference for male courtship effort can drive the evolution of male mate choice.
The evolution of male mate choice is constrained by costs of choice in species with a male-biased operational sex ratio (OSR). Previous theoretical studies have shown that significant benefits of male choice are required, for example, by mating with more fecund females, in order for these costs to be offset and a male preference to spread. In a series of population genetic models we show the no...
