Cosmetic coloration in birds: occurrence, function, and evolution
Colorful plumages are conspicuous social signals in birds, and the expression of these
colors often reflects the quality of their bearers. Since mature feathers are dead structures …

Mediterranean blue tits as a case study of local adaptation
While the study of the origins of biological diversity across species has provided numerous
examples of adaptive divergence, the realization that it can occur at microgeographic scales …

EVIDENCE FOR SEXUAL SELECTION ON STRUCTURAL PLUMAGE COLORATION IN FEMALE EASTERN BLUEBIRDS (SIALIA SIALIS)
Although the function of ornamental traits in males has been the focus of intensive research
for decades, expression of such traits in females has received much less study. Eastern …

Early birds are sexy: male age, dawn song and extrapair paternity in blue tits, Cyanistes (formerly Parus) caeruleus
Sexual selection theory predicts that signals reflecting the relative quality of individuals
should be used in mate choice. Females could base their choice of copulation partners on …

Carotenoid diet and nestling provisioning in urban and rural great tits Parus major
Considering the importance of dietary constraints for the widely held view of carotenoid
pigmentation as an honest quality indicator, there is surprisingly little data on carotenoid …

Female butterflies prefer males bearing bright iridescent ornamentation
Butterflies are among nature's most colourful animals, and provide a living showcase for
how extremely bright, chromatic and iridescent coloration can be generated by complex …

Condition dependence, quantitative genetics, and the potential signal content of iridescent ultraviolet butterfly coloration
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 these …

Quantitative genetic evidence that males trade attractiveness for ejaculate quality in guppies
Polyandry, where females mate with multiple males, means that a male's reproductive
success will depend both on his ability to acquire mates and the ability of his sperm to …

Testing the phenotypic gambit: phenotypic, genetic and environmental correlations of colour
Evolutionary theory is primarily concerned with genetic processes, yet empirical testing of
this theory often involves data collected on phenotypes. To make this tenable, the implicit …

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 …
