Is carotenoid ornamentation linked to the inner mitochondria membrane potential? A hypothesis for the maintenance of signal honesty
JD Johnson, GE Hill - Biochimie, 2013 - Elsevier
Several mechanistic hypotheses have been proposed for how carotenoid pigmentation of
integumentary structures can serve as an honest signal of individual quality. These …

A ketocarotenoid‐based colour polymorphism in the Sira poison frog Ranitomeya sirensis indicates novel gene interactions underlying aposematic signal variation
The accumulation of red ketocarotenoids is an important component of coloration in many
organisms, but the underlying mechanisms are poorly understood. In some organisms …

Diversity, physiology, and evolution of avian plumage carotenoids and the role of carotenoid–protein interactions in plumage color appearance
The diversity of vibrant plumage colors in birds has evolved as a direct result of social and
environmental pressures. To fully understand these underlying pressures it is necessary to …
