Padrões de atividade de Teius oculatus (Sauria: Teiidae) na Reserva Biológica do Lami, Estado do Rio Grande do Sul - Brasil

Teius oculatus (D'Orbigny & Bibron, 1837) é um lagarto de ampla distribuiçao no Estado do Rio Grande do Sul e muito abundante na Reserva Biológica do Lami, localizada as margens do Lago Guaíba. Os padroes de atividade foram enfocados sob 4 categorias: sob a vegetaçao, forrageio, assoalhamento e em deslocamento. O pico máximo de atividade diária ocorreu entre 09:00-11:00 horas e a atividade de maior relevancia foi sob a vegetayao (48,91%, n=687). A atividade total dos lagartos esta va correlacionada coma temperatura do substrato (r=0,9375; p<0,001; n=20). Os lagartos adultos mostraram um período anual de cinco meses de átividade, enguanto os jovens permaneceram ativos por sete meses. Nao foram registradas atividades durante o inverno, permanecendo cm suas tocas. Nao houve atividade noturna, nem em dias nublados ou chuvosos.Teius oculatus (D'Orbigny & Bibron, 1837) is a Iizard with a widespread distribution in the State of Rio Grande do Sul and very abundant at Lami Biological Reserve, Iocated near the border of the Guaíba lake. The patterns of activity have been focused under 4 categories: Rest under vegetation, foraging, basking and displacemcnt. Thc peak of daily activity was between 09:00-11:00 hours and the most relevant activity was resting under vegetation (48.91%, n=687). Total activity of the Iizards was correlated with soil temperature (r=0.9375; <0.001; n=20). Adults showed an annual period of five months of activity, while in thc juveniles it was beyond seven months. There was no activity during winter, when they was hiding themselves in their burrows. There is no nocturnal activity nor in cloudy or rainy days.Asociación Herpetológica Argentin

Observações sobre o comportamento de Liolaemus occipitalis em cativeiro (Sauria, Tropiduridae) Observations on the behavior of Liolaemus occipitaus in captivity (Sauria, Tropiduridae)

<abstract language="eng">Liolaemus occipitalis (Boulenger, 1885) is an abundant lizard lbundalong lhe coastal dunes of Rio Grande do Sul, Brazil. Fourteen individuais were manually captured in the dunes of Quintão beach (Palmares do Sul, Rio Grande do Sul) and studied in captivity from 23/VII/92 to 30/VII/93. They were kept in a terrarium with sand substrate and vegetation collected in their habitat. Snout-vent length (SVL) and wcighted were measured weekly. They received Tenebrio molitor (Linnaeus, 1758) worms as food; water was abundant. Combats between males for food and territory, and other behavioral displays were observed, like copulation and nesting behaviors. Growth curves for each lizard were analyzed
