A link between eumelanism and calcium physiology in the barn owl [PDF]

, 2018
In many animals, melanin-based coloration is strongly heritable and is largely insensitive to the environment and body condition. According to the handicap principle, such a trait may not reveal individual quality because the production of different ...

Eumelanin-based coloration and fitness parameters in birds: a meta-analysis [PDF]

, 2018
Although melanin is the most common pigment in animal integuments, the adaptive function of variation in melanin-based coloration remains poorly understood. The individual fitness returns associated with melanin pigments can be variable across species as

Pheomelanin pigment remnants mapped in fossils of an extinct mammal

Nature Communications, 2019
Chemical imaging and spectroscopy have previously been used to identify eumelanin residue in fossils and infer dark coloration. Here, Manning and colleagues develop an approach to identify pheomelanin (red pigment) residues and ascertain their ...
