Male±male competition facilitates female choice in sticklebacks
In many species, secondary sexual characteristics are used in both male^male competition and in attracting females. This suggests that social control of deception could contribute to the maintenance of honest sexual signalling. In the three-spined stickleback Gasterosteus aculeatus, male red breeding coloration plays a dual role in sexual selection by functioning as both a threat signal in male...
متن کاملSexual Selection in the Water Spider: Female Choice and MaleMale Competition
When selection acts differently on the body size of males and females, their adult sizes may diverge. The resulting sexual size dimorphism (SSD) covers an astounding range across taxa, with extreme examples in both directions (see Fairbairn et al. 2007). Generally, in most sexually reproducing animals, females are the larger sex (Andersson 1994; Fairbairn et al. 2007), which is mainly explained...
متن کاملUV wavelengths affect female mate choice in three-spined sticklebacks
Recent behavioural studies on fish have emphasized the role of ultraviolet (UV) wavelengths in mate choice. We performed female mate choice experiments, focusing on the UV wavelength range, with the three-spined stickleback, Gasterosteus aculeatus, a species in which the role of visually guided behaviour in the human-visible wavelength range (400–700 nm) has been well studied. Ripe female stick...
متن کاملNonlinear effects of female mate choice in wild threespine sticklebacks.
Sexual selection by mate choice represents a very important selective pressure in many animal species and might have evolutionary impacts beyond exaggeration of secondary sexual traits. Describing the shape and strength of the relationships linking mating success and nonsexual traits in natural conditions represents a challenging step in our understanding of adaptive evolution. We studied the e...
متن کاملThe role of ultraviolet wavelengths in the mate-choice decisions of female three-spined sticklebacks.
Female three-spined sticklebacks have been found to use visual cues when responding sexually towards courting males, often preferring more intensely red-coloured males, and males with blue rather than silver irises. However, traditionally the literature has failed to test preference across the full spectral range to which females might be sensitive, limiting analysis to the human-visible wavele...
