Evolution and function of colour signals in Podarcis lizards

Podarcis lizards exhibit a striking variability of coloration patterns involved in male/female intra- and inter-sexual selection. One of my main interests is to study adaptive co-variation of colour patterns in this genus with socio-ecological factors and individual traits, in a phylogenetic context.

In particular, this system is ideal to address some poorly understood questions in the evolution of animal colour signals, such as the social and ecological factors affecting the evolution of signal reliability,  whether different colour-producing mechanisms place different constraints on the evolution of chromatic signal honesty and reliability, or the evolution of colour polymorphisms.
