Human–wildlife conflicts in a fragmented Amazonian forest landscape: determinants of large felid depredation on livestock
Most large carnivore species are in global decline. Conflicts with people, particularly over depredation on small and large livestock, is one of the major causes of this decline. Along tropical…
Disturbance-mediated mammal persistence and abundance-area relationships in Amazonian forest fragments.

- 1 December 2007
The importance of large (>10,000 ha), relatively undisturbed forest patches to maximize persistence and maintain baseline abundances of Neotropical forest mammal species is highlighted, with information-theoretic analysis confirming that fragment area was the most important explanatory variable for the overall species richness and abundance of mammal species.
Anthropogenic determinants of primate and carnivore local extinctions in a fragmented forest landscape of southern Amazonia
Habitat fragmentation has been shown to influence the abundance, movements and persistence of many species. Here, we examine the effects of forest patch and landscape metrics, and levels of forest…
Disturbance‐Mediated Drift in Tree Functional Groups in Amazonian Forest Fragments
The composition and abundance of different tree genera were also related to time since fragmentation, distance to the nearest edge, and fire severity, despite the recent post-isolation history of the forest patches surveyed.
Biodiversity conservation in human-modified Amazonian forest landscapes
Amazonia (sensu lato) is by far the largest tropical forest region, but has succumbed to the highest absolute rates of tropical deforestation and forest degradation, driven by rapid frontier…
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…
Deforestation dynamics in a fragmented region of southern Amazonia: evaluation and future scenarios
SUMMARY The ‘arc of deforestation’ of southern Amazonia has one of the highest deforestation rates documented anywhere in the world. Landscape changes in a poorly studied but strategically important…

Results show that DNA obtained from faecal samples works efficiently for carnivore species identification in the Amazon forest and also shows potential for nuclear DNA analysis, thus providing a valuable tool for genetic, ecological and conservation studies.
Efficiency of box-traps and leg-hold traps with several bait types for capturing small carnivores (mammalia) in a disturbed area of southeastern Brazil.

This work compared the efficiency of box and leg-hold traps, using live and dead bait, to capture six carnivore species and provides recommendations for the ethical use of these trap and bait types.
Habitat patch size modulates terrestrial mammal activity patterns in Amazonian forest fragments
The hypothesis that behavioral plasticity is an important determinant of species persistence in small forest remnants dominated by edge effects is supported.
