Evaluating testosterone as a phenotypic integrator: from tissues to individuals to species
Highlights•Testosterone (T) is thought to integrate phenotypes that work well
together.•However, it is not clear how such integration is generated within the organism.•T …

Male-like female morphs in hummingbirds: the evolution of a widespread sex-limited plumage polymorphism
ES Diamant, JJ Falk… - Proceedings of the …, 2021 - royalsocietypublishing.org
Differences in the way males and females look or behave are common in animals. However,
discrete variation within sexes (sex-limited polymorphism) also occurs in several vertebrate …

The evolutionary history and mechanistic basis of female ornamentation in a tropical songbird
Ornamentation, such as the showy plumage of birds, is widespread among female
vertebrates, yet the evolutionary pressures shaping female ornamentation remain uncertain …

Testosterone induces plumage ornamentation followed by enhanced territoriality in a female songbird
We know little of the proximate mechanisms underlying the expression of signaling traits in
female vertebrates. Across males, the expression of sexual and competitive traits, including …

Evolution of female coloration: what have we learned from birds in general and blue tits in particular
Female ornaments have long been considered non-functional, but a paradigm shift has
occurred over the 2 last decades. The adaptive nature of female ornaments is now widely …
