The aim of the present study is to calculate the encounter rate and estimate the density of medium and large-sized mammals with nocturnal habits in the Cristalino region of northern Mato Grosso, southern Amazon, Brazil, using distance sampling method. Eight species were detected with encounter rate varying from 0.09 at 1.68 encounters 10 km–1, and three population densities were estimated: Cuniculus paca (7.75 individuals km–2), Potos flavus (7.08 individuals km–2) and Mazama americana (4.23 individuals km–2). Our data help expand the information about density of nocturnal mammals in the southern Amazon region, in the transition between the Amazon and the Cerrado biomes, and can contribute to management and conservation of these species

Abstract


The aim of the present study is to calculate the encounter rate and estimate the density of medium and large-sized mammals with nocturnal habits in the Cristalino region of northern Mato Grosso, southern Amazon, Brazil, using distance sampling method. Eight species were detected with encounter rate varying from 0.09 at 1.68 encounters 10 km–1, and three population densities were estimated: Cuniculus paca (7.75 individuals km–2), Potos flavus (7.08 individuals km–2) and Mazama americana (4.23 individuals km–2). Our data help expand the information about density of nocturnal mammals in the southern Amazon region, in the transition between the Amazon and the Cerrado biomes, and can contribute to management and conservation of these species
