The signalling function of melanin‐based colouration is debated. Sexual selection theory
states that ornaments should be costly to produce, maintain, wear or display to signal quality …

Sex differences in life history, physiology, and behavior are nearly ubiquitous across taxa,
owing to sex-specific selection that arises from different reproductive strategies of the sexes …

Melanin is the most widespread pigment in organisms. Melanin-based coloration has been
repeatedly observed to be associated with the same traits and in the same direction in …

Knowing how animals adapt their phenotype to local temperature and humidity is key to
understanding not only ecogeographical rules, but also how species will manage climate …

Melanin, including both eu‐and pheomelanin forms, is the most common pigment type in
animals and plays numerous adaptive roles. However, the effect of diet on melanin …

Infected hosts may preserve fitness by resisting parasites (reducing parasite burden) and/or
tolerating them (preventing or repairing infection-induced damage). Theory predicts that …

Quantifying and predicting microevolutionary responses to environmental change requires
unbiased estimation of quantitative genetic parameters in wild populations.'Animal models' …

Much of our knowledge of the drivers of immune variation, and how these responses vary
over time, comes from humans, domesticated livestock or laboratory organisms. While the …

Predicting the rate of adaptation to environmental change in wild populations is important for
understanding evolutionary change. However, predictions may be unreliable if the two key …

Abstract The melanocortin‐1 receptor (MC 1R) gene influences coloration by altering the
expression of genes acting downstream in the melanin synthesis. MC 1R belongs to the …
