Data from: Male rock lizards may compensate reproductive costs of an immune challenge affecting sexual signals

Gonzalo Rodríguez-Ruiz, Jesús Ortega, José Javier Cuervo, Pilar López, Alfredo Salvador & José Martín
Sexual signals can be evolutionarily stable if they are condition dependent or costly to the signaler. One of these costs may be the trade-off between maintaining the immune system and the elaboration of ornaments. Experimental immune challenges in captivity show a reduction in the expression of sexual signals, but it is not clear whether these detrimental effects are important in nature and, more importantly, whether they have reproductive consequences. We designed a field experiment to...
