Terrestrial mammal assemblages in protected and human impacted areas in Northern Brazilian Amazonia

Mammal communities in the vicinity of human settlements are often subject to subsistence hunting and retaliatory killings. We used fourteen digital camera traps equipped with infrared triggers to sample the medium-sized and large mammal communities for ca. 34 (-1.64) days per site. Diversity was mea...
