Fatores determinantes na ocorrência de espécies de carnívoros (Mammalia: Carnivora) em áreas degradadas na amazônia oriental

Abstract

Deforestation, habitat fragmentation, and forest impoverishment have led to a reduction in biodiversity and loss of ecosystem functions in the Amazon Rainforest. Due to the context of high anthropogenic pressure, the importance of degraded primary forests and secondary forests for the conservation of tropical species has been discussed in the literature. In this work, we investigate the characteristics of a degraded landscape have been determinant for the occurrence of species of the order Carnivora, in a context of high anthropic pressure in the eastern Amazon. As the use of photographic traps, we related environmental and landscape variables with the abundance of the species using Generalized Global Models analyzes. The responses of the carnivorous species were differentiated about some variables. However, we concluded that even in a context of high degradation, the factor that still modulates the occurrence of most carnivores is the forest, even if degraded.
