| The main objective of this study was to examine the natural history and the ecology of the species that constitute a snake assemblage in the Atlantic Rainforest, at Núcleo Picinguaba, Parque Estadual da Serra do Mar, located on the northern coast of the state of São Paulo, southeastern Brazil. The main aspects studied were: richness, relative abundance, daily and seasonal activity, and substrate use. We also provide additional information on natural history of the snakes. A total of 282 snakes, distributed over 24 species, belonging to 16 genera and four families, has been found within the area of the Núcleo Picinguaba. Species sampled more frequently were Bothrops jararaca and B. jararacussu. The methods that yielded the best results were time constrained... |

| ABSTRACT Bromeliads are important habitats for reptiles and amphibians, and are constantly used as shelter, refuge, foraging or thermoregulation sites due to their foliar architecture, which allows for constant maintenance of humidity and temperature. This study aimed to identify the herpetofauna inhabiting the non-phytotelmata rupicolous bromeliad Encholirium spectabile Mart. ex Schult. & Schult.f. and to analyze the microhabitat usage of these bromeliads by different species in the Caatinga of northeastern Brazil. From January 2011 to August 2012, we collected data by active search throughout three paralel transects in a rock outcrop in the municipality of Santa Maria, state of Rio Grande do Norte. We recorded four species of anuran amphibians, six... |

| ABSTRACT Presented is the first information on the ecological and reproductive aspects of the treefrog, Aparasphenodon brunoi Miranda-Ribeiro, 1920, living in ombrophilous forest areas of the Atlantic Rainforest, Brazil. We recorded the species’ daily activity and over the course of a year, population density during the year, microhabitat usage, diet, and some reproductive features (quantity, diameter and mean mass of oocytes, mean reproductive effort of female). Field sampling was conducted monthly from June 2015 to July 2016. Searches for treefrogs were systematic, using visual encounter surveys along 14 plots RAPELD long term research modules established in the forest. For each captured individual, we recorded the hour, microhabitat used, and perch... |

| Ischnocnema (Brachycephalidae) includes many species that are important members of the leaf litter frog communities in the Atlantic Rainforest of Brazil. Ischnocnema parva (Girard, 1853) is endemic to the Atlantic Rainforest biome and is restricted to the forests of southeastern Brazil. Currently, the available information about the ecology of I. parva is scarce. We studied the diet, the habitat use, reproduction and density of I. parva in an area of Atlantic Rainforest at the Concórdia mountain range, Rio de Janeiro. Individuals of I. parva were captured in April 2005 using different sampling methods: time constrained search (transects), plots of 5 x 5 m (25 m²) on the litter, and pitfall traps with drift fences. We found 240 frogs; 35 females and 205... |

| Three forested habitats at Pantanal of Poconé (Mato Grosso) were sampled during 17 months, with an effort of 38,635 trap-nights, resulting in a 6.3% of trapping success. Six marsupial and eight rodent species were recorded. Natural history, reproductive biology, behavior and habitat use are described for six marsupial species from the Pantanal floodplain: Caluromys philander (Linnaeus, 1758), Didelphis albiventris Lund, 1840, Gracilinanus agilis (Burmeister, 1854), Micoureus demerarae (Thomas, 1905), Monodelphis domestica (Wagner, 1842) and Philander opossum (Linnaeus, 1758). Micoureus demerarae was the species with the highest number of captured individuals (n = 240) and with the highest number of capture events (n = 1287). Reproduction of most species... |

| The aim of the present study was to provide a preliminary description of habitat use by Guiana dolphins, Sotalia guianensis (Van Bénéden, 1864) in the Paranaguá Estuarine Complex (PEC), state of Paraná, Brazil. Approximately 124 km² were surveyed by small boat from April 2006 to July 2008 in the following subsets of the PEC: Canal do Superagui (~28 km²); Pinheiros Bay (~34 km²); part of Laranjeiras Bay, which included the Guaraqueçaba sub-estuary (~38 km²); and part of the Mixture Section of the PEC (~24 km²). Our efforts were unevenly distributed in the study area. During 55 survey days covering seven distinct seasons, we spent 165 hours observing 323 groups of S. guianensis. Group size varied from two individuals to aggregations as large as approximately... |

| We studied the seasonal habitat selection of the red deer, Cervus elaphus alxaicus Bobrinskii & Flerov, 1935, in the Helan Mountains, China, from December 2007 to December 2008. Habitat selection varied widely by season. Seasonal movements between high and low elevations were attributed to changes in forage availability, alpine topography, the arid climate of the Helan Mountains, and potential competition with blue sheep, Pseudois nayaur (Hodgson, 1833). The use of vegetation types varied seasonally according to food availability and ambient temperature. Red deer used montane coniferous forest and alpine shrub and meadow zones distributed above 2,000 m and 3,000 m in summer, alpine shrub and meadows above 3,000 m in autumn, being restricted to... |

| The habitat use and feeding habits of a set of nektonic fish species often found in small low-gradient streams in Brazil were investigated. The core species in the present study was Knodus moenkhausii (Eigenmann & Kennedy, 1903), the most abundant of five species in the nektonic guild. Records of the species in 22 streams indicate that K. moenkhausii is associated, on a mesohabitat scale, with runs, and on a microhabitat scale, with sandy bottoms, intermediate depth, and open sites without coverage or submerged vegetation. During snorkeling observations, two additional nektonic registered species showed spatial segregation from K. moenkhausii with respect to foraging microhabitats. Feeding habits of the observed nektonic species were significantly... |

| The distribution and habitat use by carnivores can be assessed by studying their tracks or feces. If these methods are to be used confidently, they should not only unequivocally discriminate among species, but should also render the same patterns of spatial distributions. We assessed the fulfillment of these requirements with five carnivores inhabiting the Maulino forest of central Chile: Galictis cuja, Oncifelis guigna, Pseudalopex culpaeus, Pseudalopex griseus, and Puma concolor. Fecal bile acid thin layer chromatographic profiles were assessed, and shown to be species-specific, invariant within samples of a given individual and among individuals of a given species, but consistently different across species. The spatial distribution of feces in mixed... |

| Although Tropidurus is a widely distributed lizard genus in South America and the Galapagos Islands, studies on space use and spatial distribution are scarce. We studied the home range structure of the saxicolous lizard Tropidurus torquatus based on the inland population of a rock outcrop in Minas Gerais State, southeastern Brazil. Lizards were individually marked and observed during reproductive and non-reproductive seasons. Using the mínimum convex polygon method, we found that average total range size of males during the reproductive season was larger than that of females, and that both had similar total range sizes in the non-reproductive season. The harmonic mean method showed that males have a larger home range size than that of females during both... |

| BACKGROUND: In Chile, most of the timber industry depends on Monterey pine (Pinus radíala (D. Don.)) plantations, which now cover more than 1.5 million ha. In spite of the intensive management of these plantations, they are home to a large number of wildlife species. One of the least known groups in this type of environment are reptiles. For this reason, we conducted a study on the distribution and abundance of reptiles at plantations of different ages in seven sites in the Coastal Range of Central Chile. RESULTS: From seven species that could be potentially found in the study region, a total of five species were recorded, with Liolaemus lemniscatus (Gravenhorst) being the most abundant (with up to 160 ind*ha-1). Detectability of species was similar in... |

| Fifteen raptor species (Falconiformes and Strigiformes) breed and other two may breed in Torres del Paine National Park (Chilean Patagonia), the highest raptor species richness documented in Chile. Accounts for each raptor species in Torres del Paine are provided, including information on weight, habitat, diet, residence, conservation, and miscellaneous observations in the Park. We compare raptor species richness in Torres del Paine with well studied localities in central and northern Chile, and speculate on causes for the higher raptor diversity observed in the Park. Raptor macroniches in Torres del Paine are assessed, describing primarily their use of two major habitat types and nine food resources. We examine food-niche relationships for a subset of... |

| Some aspects of the biology and ecology (distribution pattern, feeding habits and length-mass relationship) of a population of Diamphipnopsis samali are studied in a first order stream surrounded by exotic forest located in North Patagonia, Chubut province, Argentina. Two samplings were performed during high and low water periods. All information was treated with fixed-effects 2-factor ANOVA models to assess significant differences. Mouth parts analysis of D. samali indicates that it corresponds to an intermediate type between carnivorous and herbivorous-detritivorous type. The guts content shows that the species specially fed on wood and fungal hyphae. No significant difference on the consumed food between sampling periods was found, even though there... |

| Estuarine dolphins, Sotalia guianensis (Van Bénéden, 1864), were identified in Sepetiba Bay (22º35'S, 44º03'W), state of Rio de Janeiro, Brazil, between February 1994 and July 2006 using the photo-identification method. A total of 72 surveys resulted in the identification and cataloguing of 217 individual dolphins. Seventy-nine (36%) were resighted at least once during the study period. The average interval between resightings was 40,6 ± 31,1 months. Large numbers of mother-and-calf pairs were recorded during the 12 years and new individuals were frequently encountered in the photographic records. These results suggest that part of the dolphin population is more consistently found in Sepetiba Bay, probably for feeding and reproduction, while other... |

| ABSTRACT The informations of bird species distribution in different habitats and the structure of their communities are crucial for bird conservation. We tested the differences in composition, richness and abundance of birds in different phytophysiognomies at Bodoquena Mountains, western Brazil, and we demonstrated the variations in richness and abundance of birds between different trophic groups. Sampling was conducted between July 2011 and June 2012 in 200 point counts arranged in the study area. A total of 3350 contacts were obtained belonging to 156 bird species. Woodland savannas, seasonal forests and arboreal savannas had higher bird abundance and richness, while riparian forests, clean pastures and dirty pastures had smaller values of these... |
