1. Wild pig (Sus scrofa L.) occupancy patterns in the Brazilian Atlantic forest
Resumo: Apesar dos grandes impactos da invasão do javali (Sus scrofa) nos ecossistemas naturais, o uso de hábitats por esta espécie nos neotrópicos ainda permanece pouco estudado. Aqui, nós investigamos os efeitos do hábitat local e de covariáveis da paisagem (tipos de vegetação, cursos d'água e estradas) sobre os padrões de ocupação do javali n

2. Medium and large mammals in a Cerrado fragment in Southeast Goiás, Brazil: inventory and immediate effects of habitat reduction on species richness and composition
Resumo: A fragmentação e a redução de hábitat de vegetação remanescente tem sido as principais ameaças à biodiversidade do Cerrado. Este trabalho teve como objetivo inventariar as espécies de mamíferos de médio e grande porte em um fragmento de Cerrado e avaliar a influência do desmatamento de parte desse fragmento na riqueza e composição de e

3. Medium and large sized mammals of the Boqueirão da Onça, North of Bahia State, Brazil
ABSTRACT The mosaic of protected areas of Boqueirão da Onça (8.636 km²), created in the north of Bahia state, is located in the Caatinga, an exclusively Brazilian biome, but exposed to a range of anthropic impacts that threaten its species and natural resources. Few data are available for various zoological groups in Caatinga, including mammals. In order

4. Structural differences in mammal assemblages between savanna ecosystems of the Colombian Llanos
Abstract The Colombian Orinoquia region is characterized by a high diversity of mammals, which is associated with complex ecosystems that include large extensions of Neotropical savannas (known locally as “Llanos Orientales”). Despite accelerated anthropogenic transformations in savanna ecosystems, the knowledge to design effective conservation strategie

5. Occurrence of tayras (Eira barbara Linnaeus, 1758) with anomalous coloration in Cerrado remnants in the state of São Paulo, Brazil
Resumo: Colorações anômalas são desordens geralmente de origem genética, em que a pigmentação do corpo é reduzida (hipopigmentação) ou excessiva (melanismo), em partes ou totalmente. Casos de hipopigmentação já foram documentados em muitos mamíferos neotropicais, incluindo a irara (Eira barbara Linnaeus, 1758). Nós expandimos os relatos de oco

6. Testing camera traps as a potential tool for detecting nest predation of birds in a tropical rainforest environment
ABSTRACT Identification of the predators of bird nests is essential to test ecological and evolutionary hypotheses and to make practical management decisions. A variety of nest monitoring devices have been proposed but many remain difficult to set up in the field. The aim of this study was to test camera traps as a potential tool to study predation of natura

7. Influence of vegetation physiognomy, elevation and fire frequency on medium and large mammals in two protected areas of the Espinhaço Range
ABSTRACT The objectives of this study were to determine the richness of medium and large mammal species in two protected areas of the Espinhaço Mountain Range, state of Minas Gerais, Brazil; and to investigate the factors affecting the occurrence of those species. To accomplish that we placed 49 camera traps activated by heat and motion at Rio Preto State P

8. MAMMALIAN DIVERSITY IN THE SAVANNA FROM PERU, WITH THREE NEW ADDICTIONS FROM COUNTRY
ABSTRACT Bahuaja Sonene National Park protects the unique sample of subtropical humid savannas in Peru, which are known as “Pampas del Heath” with 6,136 hectares of area. Many endangered species and/or endemic from savannas occur there, however studies about the diversity of mammals in Pampas del Heath are limited and only three assessments there have be

9. Abundance changes and activity flexibility of the oncilla, Leopardus tigrinus (Carnivora: Felidae), appear to reflect avoidance of conflict
We investigated the density and activity of the oncilla, Leopardus tigrinus (Schreber, 1775), a threatened small cat, in the Brazilian Atlantic Forest, using camera-trap data. We described differences in the activity of individuals occurring alone or in sympatry with larger cats. Oncilla presented low densities (7-13 ind./100 km²) and high flexibility in it

10. Activity pattern of Cuniculus paca (Rodentia: Cuniculidae) in relation to lunar illumination and other abiotic variables in the southern Brazilian Amazon
Understanding what influences the activity of organisms is important for both ecological understanding and species conservation. Using data from 2,707 camera trap days distributed across 24 forest sites, we present quantitative analyses of the activity pattern of Cuniculus paca (Linnaeus, 1766) in southern Amazonia. We compared the activity pattern of this s

11. Efeitos da estrutura de habitat e do espaço sobre a diversidade de mamíferos no norte do Pantanal : uma abordagem de resolução fina
Compreender os mecanismos que causam variações espaço-temporais na diversidade biológica é uma das principais atribuições da ecologia. A teoria clássica de nicho prediz que o gradiente ambiental e sua complexidade mediam processos cruciais na estruturação das assembléias locais, permitindo a coexistência das espécies. A associação entre fatore

12. Habitat partition among cervids in the Iguaçu National Park / Partição de habitats entre os cervídeos do Parque Nacional do Iguaçu
This study evaluated the determinant patterns of spatial distribution among the sympatric species Mazama americana and Mazama nana in the Iguaçu National Park under the principles of competitive exclusion and coexistence of ecologically related species. Three potential models of habitat partition were proposed to evaluate the relations among the occurrence
