Sumario:To our knowledge, there are no studies of mother-offspring recognition in Liolaemus lizards, even though many species have a refined discrimination capacity based on chemical signals, and some of them are viviparous with a close relationship between mothers and offspring. We studied the reciprocal chemical mother-offspring recognition in the viviparous species Liolaemus zullyae, evaluating whether both mothers and offspring can discriminate between their consanguineous relative from another who is not genetically related. Six females gave birth in the laboratory. Once the offspring were born, crossover experiments were carried out. The results suggest that mothers showed no clear evidence of discrimination of their own and other´s newborns. In contrast, newborns rubbed their faces for longer when scents were from other females than from their own mothers, suggesting that newborns may recognize their mothers. We discuss the asymmetric mother-offspring recognition detected in this study.
