Density and niche segregation of two armadillo species (Xenarthra: Dasypodidae) in the Vale Natural Reserve, Brazil. Repositório Alice
FERREGUETTI, A. C.; TOMAS, W. M.; BERGALLO, H. G..
We provide the first estimates of density and population size of two sympatric species of armadillos (Euphractus sexcinctus and Dasypus novemcinctus) for the Vale Natural Reserve, evaluating how poaching would be affecting their habitat use (i.e. detectability and occupancy probability) and also describing their activity patterns. Abundance and density were estimated using a distance sampling technique. Occupancy, detectability, and activity patterns were assessed using camera-trapping during a one-year period. Estimated population densities were 0.06 individuals per hectare (ind/ha) and 0.05 ind/ha for D. novemcinctus and E. sexcinctus, espectively. Occupancy probability of both species was affected by the distance to forest edge. D. novemcinctus showed a...

Population density, activity pattern and habitat use of the ocelot Leopardus pardalis in an Atlantic Forest protected area, Southeastern Brazil. Repositório Alice
WOLFF, N. M.; BERGALLO, H. G.; FERREGUETTI, A. C.; TOMAS, W. M..
The ocelot Leopardus pardalis (Linnaeus, 1758) is a nocturnal opportunistic felid that has a wide geographic distribution in almost every American continent. Although this species is classified as Least Concern, its populations have been declining as a direct consequence of the destruction of their habitats. Information on the density, occupancy and factors influencing habitat use of ocelots is of great importance for the establishment of action plans aimed for conservation. We studied ocelots in a protected area of the Atlantic Forest, Vale Natural Reserve, state of Espírito Santo, Brazil. We estimated density, characterized activity patterns, and evaluated how habitat use was influenced by six covariates. Estimated density (MeanSE; 45.845.45 ocelots per...

The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the...

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,...
