| ABSTRACT Death-feigning behaviour occurs when the animal simulates a state of immobility. This behaviour is described for some lizard families, among them the family Gymnophthalmidae with only one record. Iphisa elegans is a diurnal and terrestrial Amazonian gymnophtalmid lizard. It has cryptic behavior and moves rapidly on the ground, hindering observations of its behavior. We report a case at the Comodoro Municipality, Mato Grosso State, Brazil. An adult male of I. elegans, when manipulated, turned its venter up and put itself in a death-feigning posture. This species is preyed upon by birds, snakes and other lizards¸ possibly behaving this way when the cryptic behaviour or escape attempt fails. More studies are necessary to evaluate the efficiency of... |

| El uso de productos extraídos o provenientes de la fauna silvestre es relevante para el desarrollo económico y el bienestar social en muchos lugares del mundo. Sin embargo, frecuentemente la fauna silvestre entra en los circuitos de tráfico ilegal para abastecer los mercados de mascotas y productos como pieles, plumas, "carne de monte", entre otros. El tráfico ilegal genera enormes presiones sobre las especies sujetas a extracción y es una de las principales amenazas para estas. En Colombia, el tráfico de tortugas es de importancia debido a los volúmenes explotados y al significado que tienen sus productos para las comunidades. Mediante el Análisis de Redes se caracterizó espacialmente, a nivel de Departamento, el tráfico de los cinco géneros de... |

| The reptile Kinosternon scorpioides is a freshwater chelonian, popularly known as jurará, and is found in the Baixada Maranhense, Maranhão State, Brazil. Due to the lack of scientific information on the reproductive biology of the species, current paper describes the body and testicular biometry and the gonad-somatic index (GSI) in adult specimens collected from the natural environment. Twenty male adults were collected in the rainy (n = 10) and dry (n = 10) seasons. Data were derived from the body, testis size and GSI and tests of correlation between these measures were performed. The body biometrics of free-living Kinosternon scorpioides is similar to those found in other studies for adult animals bred in captivity. The body weight was higher in animals... |

| The broad-snouted caiman, Caiman latirostris, is widely distributed in countries of South America. In Brazil it is considered an endangered species because of natural habitat destruction and illegal hunting. In reptiles, the thyroid gland plays an integral part in ecdysis, reproduction, tail regeneration, growth, endocrine function and metabolism rate. The aim of the present study was to characterize the thyroid gland morphology of C. latirostris, based on histochemical and immunohistochemical techniques. The thyroid glands were fixed in Bouin's fluid and serial cross sections were stained with hematoxylin-eosin, Mallory’s trichrome, periodic acid-Schiff (PAS) and Alcian blue (AB pH 1.5 and 2.5). The immunohistochemical technique for 5-HT-IR cells was... |

| The results of a study on nematode fauna occurring in wild iguanas (Iguana iguana) from Brazilian Northeast (Alagoas and Maranhão) and Central-west (Goiás and Mato Grosso) areas were presented. Six adult iguanas, three males and three females, were necropsied and the digestive system removed to examination. All the iguana specimens were heavily parasitized. The helminths diagnosed were: Ozolaimus cirratus in the cecum and colon of five iguanas; Ozolaimus megatyphlon in cecum, colon and rectum of three iguanas; and Alaeuris vogelsangi in the small intestine, cecum, colon and rectum of five animals. Two larvae of Ozolaimus sp. were recovered from the pyloric region of the stomach of one iguana. The three diagnosed species of nematodes were reported for the... |

| ABSTRACT Boids are large, constrictor snakes that feed mostly on mammals, reptiles, and birds. These animals are commonly raised as pets, and their improper handling can favor the emergence of fungal infections, which can lead to dermatological diseases that are undiagnosed in nature. Here, we isolate and identify the filamentous fungi that compose the mycobiota of the scales of boid snakes kept in captivity at the Biological Museum of the Butantan Institute. Thirty individuals of four species were evaluated: four Eunectes murinus, twelve Boa constrictor constrictor, seven Corallus hortulanus, and seven Epicrates crassus. Microbiological samples were collected by rubbing small square carpets on the snake scales. We isolated five genera of fungi:... |

| Despite the increase in herpetofaunal inventories in the Caatinga biome, information for many areas is still lacking and new surveys are required. We conducted a 30-day inventory of the herpetofauna of the Catimbau National Park, Pernambuco State, Brazil. Thirty-seven pitfall trap arrays composed of 4 buckets each, along with glue traps and active searches were used to sample local herpetofaunal diversity. We recorded 21 species of frogs, 25 lizards, 11 snakes, and 1 chelonian. All sampling methods contributed significantly to achieve the amphibian and reptile diversity recovered in the inventory. Rarefaction curves and richness estimators suggest that local biodiversity is still underestimated. We attempted to show the great potential of Catimbau National... |

| Anti-predator mechanisms in snakes are diverse and complex, including mimetic behavior. Some snakes triangulate their head, probably mimicking other more dangerous snakes. However, there is a lack of studies that demonstrate the effectiveness of this behavior with natural predators. The aim of this study was to verify, using artificial snakes, if snakes with triangular heads are less susceptible to attack by predators, and if predatory attack is targeted to the head of serpents. Artificial snakes were systematically arranged on a road border. The rate of attacked models was 48.71%. Number of attacks on models with rounded head was significantly higher than in models with triangular head. There was a significant difference between the places of attack on... |

| The loss and modification of habitats by humans have been considered key factors in the decline of diversity of species worldwide. However, the real effect caused by these disturbances on the biota is still poorly understood. The assessment of the changes in the network of interspecific interactions, such as predation rates on the native fauna, can be an important tool to diagnose the functionality of disturbed ecosystems. In this study we evaluate the predation rate on snakes in coastal grasslands in South America under human influence. Predation rate of artificial snakes, unlike that obtained in other studies, was lower in human-altered areas than preserved ones. Our findings may be due to a reduction in the abundance and/or richness of species of native... |

| Species inventories are useful tools to improve conservation strategies, especially in highly threatened biomes such as the Brazilian Atlantic Forest. Here we present a species list of amphibians and reptiles for the Reserva Ecológica de Guapiaçu (REGUA), a forest reserve located in the central portion of Rio de Janeiro state, Brazil. The list results from an extensive sampling effort that lasted ten years. A total of 73 amphibian (of which ten are endemic to the state) and 37 reptile species was recorded from the area. Five amphibian species are presently categorized by the IUCN as “data-deficient”, two as “near threatened” and one as “endangered”, whereas one reptile species is categorized as “vulnerable”. Our results showed that REGUA harbors about... |

| ABSTRACT: Although, serological studies for leptospirosis in iguanas have already been performed, there is no report in the Amazon region. Therefore, the present study aimed to investigate the presence of anti-Leptospira sp. in free living Iguanas-verdes (Iguana iguana) of Mangal das Garças Park, metropolitan region of Belém, Pará, Northern region of Brazil. Twenty-nine blood samples of Iguana-verde (I. iguana) were collected from Mangal das Garças Park. For the serological diagnosis of Leptospira sp. it was employed microscopic agglutination test (MAT) with 25 live antigens of Leptospira sp. as antigens. It was observed that all samples were non-reactive, suggesting no exposure to the agent. |

| Para determinar la concentración de DDT y sus metabolitos en ejemplares de cocodrilos (Crocodylus acutus y C. moreletii), durante el período de junio a diciembre de 2004 se tomaron 80 muestras de sangre en 37 localidades de 13 estados de la zona costera de México. En algunos de estos sitios, ha sido aplicado el DDT para el control del vector del paludismo. Las muestras fueron procesadas en el laboratorio mediante cromatografía de gases con detector de captura de electrones. Se realizó un análisis de regresión lineal simple entre la longitud y el peso de los cocodrilos. Para comparar las concentraciones de DDT en sangre en función de la longitud y peso de los cocodrilos en las provincias biogeográficas, se realizó el análisis de varianza utilizando un... |

| Sobre la base de una evaluación del estado de conservación de la herpetofauna de Argentina, publicada recientemente, se analizan los factores determinantes del estatus asignado, con énfasis en las especies de las categorías que indican una mayor amenaza. De los 484 taxa evaluados el 23 % tiene problemas de conservación. Una proporción importante de estas especies tiene áreas de distribución restringidas, especialización en el uso del hábitat, está poco protegida y sufre acciones extractivas. Se analizan los principales factores de amenaza sobre los herpetozoos, encontrándose que la mayoría está afectada por la alteración del hábitat. Los reptiles sufren el comercio más intensamente que los anfibios. Se comparan los resultados de la nueva evaluación con la... |

| The development of claws in different reptiles and their cornification are analyzed using histological, ultrastructural and autoradiographic methods. Claws develop at the tip of digits in relation to the growth of the terminal phalanx and appear as modified scales. The apical epidermis of digit becomes thickened and is associated with a mesenchymal condensation or a dense mesenchyme. The dorsal side of the digit becomes the unguis while the ventral side becomes the sub-unguis. The corneous layer in the unguis is thicker than in the sub-unguis and accumulates hard-keratin while corneocytes remain separated or partially fused. Bundles of hard-keratin tend to accumulate in parallel orientation with respect to the surface and are directed toward the claw tip.... |

| An evaluation of the existing SPIX/WAGLER type material in the museums in Munich and Leiden is given. It transpired that a considerable part of the type material, which was thought to have been destroyed during the second world war, is still extant. The material is described briefly, its presenttaxonomic status is discussed and, where necessary, lectotypes are selected. Arising from this survey a number of nomenclatural changes are necessary. Natrix cinnamomea Wagler is here considered a species incertae sedis, possibly a species of Pseutes, which contrasts with the current opinion that this is a species of Chironius. BotbropsMegaera Wagler and B. leucurusWagler are consideredconspecifie and should be known under the name B. leucurus Wagler. Both B. Furia... |
