BELVER, Luciana C.; KOZYKARISKI, Mónica l.  and  AVILA, Luciano J.. Diferencias sexuales y etarias en la actividad diaria y estacional de una población de Liolaemus koslowskyi (Liolaemini). Cuad. herpetol. [online]. 2010, vol.24, n.2, pp.71-79. ISSN 1852-5768.

The pattern of activity of Liolaemus koslowskyi populations from NE of the La Rioja Province, were studied between October 1998 and April 1999 by performing transects between 08:00 and 19:00 hs. The species present unimodal pattern of activity during both autumn, and spring; and bimodal pattern during summer. In terms of the number of active individuals, there was a significant difference between adults and juveniles in February and April and not there was significant difference between males and females. The males were active at higher temperature ranges than females and juveniles; which could suggest that would be related to territorial defense by males.

Keywords : Patterns of activity; Liolaemus koslowskyi; Monte; Argentina.
