13. Relaciones espaciales y alimenticias del ensamblaje de reptiles del complejo cenagoso de Zapatosa, departamento del Cesar (Colombia)
To find environmental factors that favors richness and abundance of species and groups of reptiles, his preference for microhabitats, species diet and differences between habitats in parameters such as size of individuals, level of detection and proportion of predation, we made four field trip in surrounding areas of the Zapatosa's wetland complex, between N

14. Discrimination of anxiety- versus panic-like behavior in the wall lizard Tropidurus oreadicus
A behavioral test battery is proposed for wall lizards (Tropidurus oreadicus) that consists of inducing tonic immobility (TI) followed by post-TI behavioral scoring. After the induction of TI, the usual behavioral sequence was flight followed by freezing and tongue-flicking and/or thigmotaxis, with flight being more probable than freezing. These sequences we

15. Reproduction and diet of Imantodes cenchoa (Dipsadidae: Dipsadinae) from the Brazilian Amazon
Imantodes cenchoa (Linnaeus, 1758) is distributed from the east coast of Mexico to Argentina. In Brazil, it occurs in the north, central-west and northeast regions. We present information on the reproductive biology and diet of I. cenchoa from analysis of 314 specimens deposited in the Herpetological Collection of the Museu Paraense Emílio Goeldi (MPEG). Im

16. Diet of two sit-and-wait lizards, Phyllopezus pollicaris (Spix, 1825) (Phyllodactylidae) and Hemidactylus mabouia (Moreau de Jonnès, 1818) (Gekkonidae) in a perianthropic area of Mato Grosso do Sul, western Brazil
A composição da dieta de duas espécies de lagartos senta-e-espera, Hemidactylus mabouia e Phyllopezus pollicaris, que coocorrem sobre substratos rochosos e paredões rochosos em uma área periantrópica no oeste do Brasil, foi descrita. Ambas as espécies demonstraram um padrão de alimentação generalista, alimentando-se principalmente de insetos. As pr

17. Indirect evidence of predation and intraspecific agression in three sympatric lizard species from a semi-arid area in northeastern Brazil
We analyzed the frequency of tail autotomy, toe amputation and integument scars in three sympatric lizard species, Ameivula ocellifera, Tropidurus hispidus and T. semitaeniatus, from a Neotropical area of semi-arid Caatinga, in northeastern Brazil. We evaluated intraspecific differences in the frequency of injuries between the sexes within each species. Only

18. VARIAÇÃO TEMPORAL E SAZONAL NA ESTRUTURA E REPRODUÇÃO DE UMA TAXOCENOSE DE LAGARTOS EM UMA ÁREA DE CAATINGA DO ALTO SERTÃO SERGIPANO. / TIME AND SEASONAL VARIATION IN THE STRUCTURE AND REPRODUCTION OF ONE OF LIZARDS IN A ASSEMBLAGE AREA OF HIGH CAATINGA SERTÃO SERGIPE.
Em ambientes de caatinga são frequentes eventos climáticos catastróficos que acabam por modelar a vida animal e vegetal neste bioma. Assim, este trabalho teve por finalidade avaliar como as espécies de lagartos do Monumento Natural Grota do Angico, Sergipe, respondem às variações ambientais em termos temporais e sazonais. Para isso foram utilizadas in

19. Feeding ecology of the pygmy gecko Coleodactylus natalensis (Squamata: Sphaerodactylidae) in the Brazilian Atlantic Forest
We studied the feeding ecology of a population of Coleodactylus natalensis Freire, 1999, an endemic gecko of Atlantic Forest fragments in the state of Rio Grande do Norte, northeastern Brazil. Lizards (N = 49) were collected manually through active search in the four habitats of Parque Estadual Dunas de Natal, type locality of the species. In the laboratory,

20. Sequence variation in the melanocortin-1 receptor (MC1R) pigmentation gene and its role in the cryptic coloration of two South American sand lizards
In reptiles, dorsal body darkness often varies with substrate color or temperature environment, and is generally presumed to be an adaptation for crypsis or thermoregulation. However, the genetic basis of pigmentation is poorly known in this group. In this study we analyzed the coding region of the melanocortin-1-receptor (MC1R) gene, and therefore its role

21. Prováveis significados paleoambientais das pinturas rupestres zoomorfas do parque nacional serra da Capivara PI. / Possible meanings of paleoenvironmental zoomorphic paintings of the National Park of Capybara - PI.
In Serra da Capivara National Park and adjacencies there is a wide range of archeological sites which provides diverse information about the first human settlements in America since it holds many characteristics from their existence in different ecosystems of the region. There are more than 1,000 registered sites (not definitive) in the park, about 657 of th

22. Morfologia hemipeniana dos lagartos microteídeos e suas implicações nas relações filogenéticas da família Gymnophthalmidae (Teiioidea: Squamata) / Hemipenial morphology of microteiid lizards and their implications on phylogenetic relationships of the family Gymnophtalmidae (Squamata: Teiioidea)
A família Gymnophthalmidae é composta por cerca de 220 espécies de lagartos de pequeno a médio porte, alocadas em 48 gêneros e distribuídas desde o sul do México até a Argentina, além do Caribe e outras ilhas das Américas do Sul e Central. Atualmente a família é reconhecida como um grupo monofilético bem sustentado por caracteres morfológicos e

This study contributes to knowledge of the family Gymnophthalmidae, adding new genetic data of three genes for the tribe Ecpleopodini and description of 11 new karyotype for the family, belonging to the tribes Ecpleopodini, Heterodactylini, Iphisiini and Gymnophthalmini. Phylogenetic analysis for the tribe Gymnophthalmini aimed to investigate the position of
