1. Community structure and population dynamics of small mammals in an urban-sylvatic interface area in Rio de Janeiro, Brazil
ABSTRACT The Atlantic Forest is one of the most disturbed Brazilian biomes, with 183 out of 298 species of mammals occurring in the state of Rio de Janeiro. In this study, we aimed to characterize the diversity, community structure, and habitat use of small mammals in the FIOCRUZ Atlantic Forest Campus (CFMA), including areas of Pedra Branca State Park (PBSP

2. MAMÍFEROS NO VOLADORES DEL PARQUE NACIONAL SANGAY, ECUADOR
ABSTRACT In this study we present the results of inventory efforts of non-volant mammals in Sangay National Park (SNP), one of the least studied regions of Ecuador. We conducted inventories at 9 locations between December 2010 and June 2015 along a gradient of elevations between 1.300 and 3.650 m. To document the presence of non-volant mammals we used captur

3. How much effort should be employed for surveying a low-diversity Amazonian mammal assemblage using line-transects?
Line-transect surveys are commonly used for sampling large mammals, but estimates of the effort needed to reliably surveying low-diversity assemblages of mammals are scarce. Using data from line-transects and species accumulation curves, I examined whether or not a sampling effort previously suggested to survey mammals elsewhere (ca. 85-100 km) would be sati

4. Caracterização da comunidade de mamíferos de médio e grande porte em paisagem agrícola fragmentada / Characterization of the mid and large bodied mammal community in a fragmented agricultural landscape
Agricultural expansion is a major cause of habitat fragmentation, leading to a reduction and isolation of natural areas. It is therefore important to understand the role of agricultural landscape structure and dynamics in maintaining local biodiversity. We aimed to describe how the structure and dynamics of an agricultural landscape influenced the community

5. Diversidade, diferenciação e biogeografia de pequenos mamíferos não-voadores na Mata Atlântica ao norte do rio São Francisco Centro de Endemismo Pernambuco / Diversity, differentiation and biogeography of non-volant small mammals of the Atlantic Forest north of São Francisco river - Pernambuco Endemism Center
The Brazilian tropical rainforests (Amazon and Atlantic Forest) present high species diversity and are currently separated by a belt of open and dry vegetation. Part of this belt is occupied by the Caatinga, where are found the Brejos de Altitude, evidence of the historical connections between the Atlantic Forest and the Amazon. The Pernambuco Endemism Cente

6. Influence of pitfall trap size and design on herpetofauna and small mammal studies in a Neotropical Forest
One of the most commonly used sampling techniques to capture leaf litter amphibians, lizards and small mammals is a set of pitfall traps with drift fences. However, there are still many speculations concerning the effectiveness of different designs of pitfall traps and the most adequate size of each trap. To address this problem, we conducted the first stand

7. Effects of habitat and landscape characteristics on medium and large mammal species richness and composition in northern Uruguay
The increasing world population and demand for food and other products has accelerated the conversion of natural habitats into agricultural lands, plantations and urban areas. Changes in habitat and landscape characteristics due to land-use change can have a significant effect on species presence, abundance, and distribution. Multi-scale approaches have been

8. Técnicas de amostragem e a detecção de mamíferos terrestres na Floresta Amazônica.
Though used extensively the diurnal line-transect census method does not provide high quality information on the occurrence and abundance of many mammal species in the Amazonian forest, especially for larger and less abundant species. This study evaluated the effectiveness of diurnal line-transects with nocturnal line-transects and camera traps to detect ter

9. Status conservacionista da mastofauna em fragmentos de Mata AtlÃntica Nordestina / Conservationist status of mammalls on atlantic forest fragments of brazilian northeastern
The aim of this study was to sample the medium and large sized mammalian fauna of the RPPN Frei Caneca and the surrounding area, comparing its abundance and diversity amongst four fragments of different sizes. The sample followed the Line Transect Method, when trails measuring between 1,3 and 2 km were established (depending on the size and shape of the frag

10. Censo de mamÃferos em alguns fragmentos de Floresta AtlÃntica no Nordeste do Brasil
Dentre os grandes biomas ameaÃados no mundo, a Floresta AtlÃntica se destaca pela sua grande diversidade, seu alto grau de endemismos e o intenso processo de devastaÃÃo sofrido nos Ãltimos cinco sÃculos. O conhecimento da comunidade de mamÃferos à fundamental para a implementaÃÃo de aÃÃes que visem o manejo e conservaÃÃo de Ãreas naturais. Par

11. Levantamento preliminar da mastofauna da região de Anajás-Muaná, Ilha de Marajó, Pará, Brasil
A short inventory of the mammalian fauna occurring in an area of the Marajó Island was performed during the rainy season. In addition to captures by using Sherman and Tomahawk traps, and mist-nets, indirect evidence was considered, e.g. finding of body fragments of specimens, vocalization, and testimonies from local people. A total of 57 species (22 familie
