We studied the relationship between the presence of jaguar and that of medium and big sized mammals which are its potential prey. The study area was divided in 34 blocks of 1km2 where we record track series (signs of presence of an individual) of big mammals (>12kg), medium sized mammals (1.5 – 12 kg) and presence (1) – absence (0) of jaguar. We calculated a Relative Abundance Index (RAI) and a richness index for each block, and we analyzed that with generalized linear models. We detected 16 species of wild mammals and recorded the presence of jaguar 8 times. Our results suggest that jaguar presence increases at the more relative abundance of big sized mammals. Among those, the tapir (Tapirus bairdii) and the white-lipped peccaries (Tayassu pecari) are important and endangered as the jaguar itself.
