| a potential recovery of a population of the sand lizard liolaemus lutzae mertens, 1938 in an area within its range: a lizard endemic and threatened with extinction. | the endemic and threatened lizard liolaemus lutzae has a relatively small geographic range restricted to only 200 km of along the coast of rio de janeiro state, brazil, which are habitats under intensive anthropic disturbance. at the barra da tijuca beach, in rio de janeiro city an estimate of the population abundance made in 1991, compared to a previous estimate made in 1984, showed a considerable decrease (about 65%). most of the decrease was attributed to anthropic disturbances that locally a ... | 2009 | 19347163 |
| endemic and threatened tetrapods in the restingas of the biodiversity corridors of serra do mar and of the central da mata atlântica in eastern brazil. | biodiversity corridors comprise a mosaic of land uses connecting fragments of natural forest across a landscape. two such corridors have been established along the eastern coast of brazil: the serra do mar and the central da mata atlântica corridors, along which most of the coastal plains are restinga areas. in this study, we analyze the present status of the endemic and endangered terrestrial vertebrates of both corridors. we sampled 10 restingas in both corridors, recording species of amphibia ... | 2005 | 16025914 |
| influences of sex, ontogeny and body size on the thermal ecology of liolaemus lutzae (squamata, liolaemidae) in a restinga remnant in southeastern brazil. | variations in body temperature (tb) of lizards can be partially explained by intrinsic factors such as sex, ontogeny and body size. liolaemus lutzae is a lizard species restricted to restingas in the brazilian coast in the state of rio de janeiro. herein, we studied sexual dimorphism and influences of sex, ontogeny, and body size to the tb of l. lutzae. adult males were larger than adult females, probably due to both intersexual selection and intra-sexual selection. there was intersexual differe ... | 2013 | 24229803 |
| seasonal variations in behaviour of thermoregulation in juveniles and adults liolaemus lutzae (squamata, liolaemidae) in a remnant of brazilian restinga. | adaptations of lizards inhabiting hot arid environments should include mechanisms of behavioural thermoregulation. in contrast, in environments with lower temperatures lizards tend to behave as thermoconformers. herein we aim to infer thermoregulatory behaviours exhibited by liolaemus lutzae (a lizard species endemic to restingas in the coast of the state of rio de janeiro, brazil) in two different seasonal thermal environments. in the dry season, the body temperatures (tb) of the lizards were h ... | 2013 | 23941976 |
