Can older males deliver the good genes?
Females of many species choose to mate with old rather than young males, possibly because older males pass superior genes on to their offspring. Recent theoretical and empirical investigations haveExpand

Fighting without weaponry: a review of male-male contest competition in butterflies
Abstract. The males of many butterfly species compete via pair-wise intrasexual contests, yet lack any obvious morphological traits conventionally associated with animal aggression. The evolution ofExpand

Gaping Displays Reveal and Amplify a Mechanically Based Index of Weapon Performance
Physical prowess, a key determinant of fight outcomes, is contingent on whole‐organism performance traits. The advertisement of performance, via display, is poorly understood because it is unclearExpand

An Integrative Framework for the Appraisal of Coloration in Nature
The world in color presents a dazzling dimension of phenotypic variation. Biological interest in this variation has burgeoned, due to both increased means for quantifying spectral information andExpand

The question of why territorial residents usually win asymmetrical owner-intruder contests is critical to our understanding of animal contest evolution. Game theory suggests that, under certainExpand

Female mating biases for bright ultraviolet iridescence in the butterfly Eurema hecabe (Pieridae)
Exaggerated male-limited coloration is widespread among butterflies, yet convincing demonstrations of intraspecific mating preferences for signal brightness and/or chromaticity are relatively rare inExpand

Predicting the direction of ornament evolution in Trinidadian guppies (Poecilia reticulata)
Sexual selection is thought to be opposed by natural selection such that ornamental traits express a balance between these two antagonistic influences. Phenotypic variation among populations mayExpand

Abstract Structural colors result from an interaction between light and the fine-scale physical structure of a surface, and are often extremely bright, chromatic, and iridescent. Given that theseExpand

Iridescent ultraviolet signal in the orange sulphur butterfly (Colias eurytheme): spatial, temporal and spectral properties
Many of nature’s most striking animal colours are iridescent, exhibiting a high degree of spectral purity and strong angular dependence of intensity and hue. Although a growing number of studies haveExpand

Ornamental evolution in Trinidadian guppies (Poecilia reticulata): insights from sensory processing-based analyses of entire colour patterns
The evolution of exaggerated sexual ornamentation is classically thought to proceed as a compromise between opposing vectors of sexual and natural selection. In colour-based ornamentation, asExpand
