Abstract

Short Notes Chemical stimuli mediate species recognition in Podarcis wall lizards Diana Barbosa 1,2 , Ester Desfilis 1 , Miguel A.

Results from several taxa suggest that behaviour plays a major role in preventing interspecific matings. Differences in mating signals between species are often much more marked than morphological differences and provide a major barrier to gene exchange, which may lead to speciation (Uzendoski and Verrell, 1993; Butlin and Ritchie, 1994).
