Yolk testosterone shapes the expression of a melanin-based signal in great tits: an antioxidant-mediated mechanism?

The Journal of experimental biology - 15 Sept 2010

Galván Ismael, Alonso-Alvarez Carlos

Abstract excerpt

Conspicuous traits produced by melanin deposition in integuments are often involved in visual communication. The information content of melanin-based signals is unclear as their expression is tightly controlled by genes and, apparently, is less dependent on individual condition. In birds, high heritabilities have been attributed to melanin-based plumages, often on the basis of egg-swapping manipulations...
