Abundance changes and activity flexibility of the oncilla, Leopardus tigrinus (Carnivora: Felidae), appear to reflect avoidance of conflict Rev. Bras. Zool.
Oliveira-Santos,Luiz Gustavo R.; Graipel,Maurício E.; Tortato,Marcos A.; Zucco,Carlos A.; Cáceres,Nilton C.; Goulart,Fernando V. B..
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 its activity. The oncillas were primarily nocturnal in the absence of other larger cat species - margay, ocelot and puma - but became more diurnal, with a cathemeral activity pattern, when the other cats were present. Oncilla is likely to be in a subordinate position in interactions with larger cats and changes its activity to decrease the chances for interspecific encounters. In this study, however, the...

Common Vampire Bat (Desmodus rotundus) feeding on Lowland Tapir (Tapirus terrestris) in an Atlantic Forest remnant in southeastern Brazil Biota Neotropica
Gnocchi,Ariana Pignaton; Srbek-Araujo,Ana Carolina.
Abstract There are few studies on the diet of Common Vampire Bat (Desmodus rotundus), despite its wide geographic distribution. The species is considered exclusively hematophagous, and medium and large-sized mammals are their main prey. In this study we report evidences of Common Vampire Bat feeding on Lowland Tapir (Tapirus terrestris) in a protected area located in the north of the state of Espírito Santo, southeastern Brazil, from camera trap records. The bat tried to access the Lowland Tapir by the posterior dorsolateral side of the body, and used the mean stratum of the vegetation as a point of support and observation between the consecutive offensives on the prey. In the same reserve, there were also two events of bat offensives on domesticated ox...

Density estimates and conservation of Leopardus pardalis southernmost population of the Atlantic Forest Iheringia, Sér. Zool.
Kasper,Carlos B.; Mazim,Fábio D.; Soares,José B. G.; Oliveira,Tadeu G. de.
ABSTRACT Using camera traps and capture/recapture analyses we recorded the presence and abundance of cat species at Turvo State Park, in southern Brazil. Ocelot [Leopardus pardalis (Linnaeus, 1758)] population density was estimated for two areas of the park, with differing management profiles. Density estimates varied from 0.14 to 0.26 indiv. km2. Another five cat species were recorded at very low frequencies, precluding more accurate analyses. We estimate 24 to 45 ocelots occur in the reserve, which is probably too small for long-term maintenance of the population, if isolated. However, if habitat integrity and connectivity between the Park and the Green Corridor of Misiones is maintained, an estimated ocelot population of 1,680 individuals should have...

Large and medium-sized mammals from Chandless State Park, Acre, Brazil. Mastozool. neotrop.
Borges,Luiz H. M; Calouro,Armando M; de Sousa,Jesus R. D.
The Neotropical region hosts the greatest diversity of mammals in the world. Western Amazonia, where the State of Acre is located, harbors one of the highest mammalian species diversity in the Neotropics. Mammals are considered important biodiversity components and play a key role in regulating and structuring forest ecosystems. However, there are considerable knowledge gaps regarding species distribution and rich­ness in the Amazon region. This study aims at documenting the medium and large-sized mammal species in Chandless State Park (PEC - Parque Estadual Chandless) giving special attention to those classified as rare or threatened. Four different methods were used in two years of research, 2008 and 2013: linear transect, camera trap, interviews and...

Mammal inventories in Seasonal Neotropical Forests: traditional approaches still compensate drawbacks of modern technologies Iheringia, Sér. Zool.
Carvalho,William D.; Rosalino,Luís M.; Adania,Cristina H.; Esbérard,Carlos E. L..
ABSTRACT Variation in body size, behavior, feeding habits and habitat use patterns in medium- and large-sized mammals influence the adequacy of sampling methods to register presence and abundance. Moreover, even if methods are similarly adequate, different methodologies result in distinct cost-efficiency relationships (i.e. some may have reduced costs, be less time-consuming and/or require less-skilled technicians). Focusing on three different sampling methods commonly used to monitor medium and large mammals in seasonal tropical forests, we compared the species richness detected by each method and quantified their cost-efficiencies: (1) camera traps; (2) line transects for direct observations of animals; and (3) line transects seeking tracks/footprints....

The importance of protected areas for conservation of bare-faced curassow (Crax fasciolata spix, 1825) (Galliformes: Cracidae) in the São Paulo State, Brazil Biota Neotropica
Gomes,Ana Paula Nascimento; Fornitano,Larissa; Costa,Rômulo Theodoro; Angeli,Thaís; Morais,Kimberly Danielle Rodrigues de; Olifiers,Natalie; Bianchi,Rita de Cassia.
Abstract The Bare-faced Curassow Crax fasciolata (Cracidae:Cracinae) is a vulnerable species that was classified as critically endangered by the São Paulo State -Brazil, in 2008. Specialists recommended "searches for areas where there may be a few remaining populations and protection of the last remaining semideciduous forest in the State". Protected areas were investigated in the Cerrado and semideciduous forest in São Paulo State by camera trapping to evaluate the presence of the Bare-faced Curassow. Eight protected areas in Cerrado biome were investigated, but the Bare-faced Curassows was recorded only at Furnas do Bom Jesus State Park (2,069 ha), São Paulo State despite the large sampling effort in larger protected areas such as the Santa Bárbara...

The Jaguarundi (Puma yagouaroundi) in the Kaa-Iya del Gran Chaco National Park, Santa Cruz, Bolivia Mastozool. neotrop.
Maffei,Leonardo; Noss,Andrew; Fiorello,Christine.
Jaguarundis are felids that inhabit almost all habitat types below 2200 m, but basic aspects of their biology and behaviour are still unknown. This study was carried out using camera traps to register the species' activity pattern in dry Chaco habitats. Jaguarundis were exclusively diurnal with a decline in activity during the warmer hours. Also, photographs showed a coat color ratio of two grey individuals for one orange.

Using activity and occupancy to evaluate niche partitioning: the case of two peccary species in the Atlantic Rainforest, Brazil. Repositório Alice
FERREGUETTI, A. C.; DAVIS, C. L.; TOMAS, W. M.; BERGALLO, H. G..
Collared and white-lipped peccaries (Pecari tajacu and Tayassu pecari, respectively) are widely distributed, herd-forming ungulates that are sympatric in a variety of Neotropical ecosystems. Patterns of co-occurrence and niche partitioning are still poorly understood in sympatric peccary populations in the Atlantic Forest. We aimed to test the hypothesis that the collared and white-lipped peccary avoided each other by some degree of niche partitioning in the Vale Natural Reserve, Espírito Santo state, southeastern Brazil. Species-specific occupancy, detection, and activity patterns were estimated from camera-trap data collected at 39 sample sites over a 1-year period. We found that both peccary species respond to similar habitat covariates (palm density,...
