Abstract

Behavioural cues in sex recognition by two species of nocturnal lizards: Eublepharis macularius and Paroedura pictus Ch. Brillet CNRS-Ethology, UPR 38, 31 ch. Joseph Aiguier, 13402 Marseille 09, France Abstract. Although several senses are used in agonistic and sexual behaviours by Eublepharis macularius and Paroedura pictus, different cues do not have the same relative value for males of the two species. Behavioural patterns observed in the presence of anesthetized conspecifics of both sexes differed consid- erably. The agonistic and sexual behaviours of E. macularius underwent progressive changes in reaction time and the frequency and duration of other behaviours. Aggressive behaviour eventually almost com- pletely disappeared in P. pictus and was replaced by sexual behaviour, whatever the sex of the stimulus- animal ; the lizards then appeared to be incapable of distinguishing males from females.
