Introduction Methods of collection:1. Interception traps and fall("pit-fall traps with drift fence"). 2. Active visual search time limited. 3. Casual Encounter. In Brazil, the 26,000 snakebites, 90% are of the genus Bothrops, and Bothrops atrox species predominant in the Amazon region including all the Brazilian Amazon. Research shows that using stable isotopes, we can verify the isotopic composition of tissues of animals that depend mainly on food, water ingested and inhaled gases. Isotopic analysis Bothrops atrox Objectives For this study, samples taken from Bothrops atrox (B. atrox) in forest using pitfall traps and fall ("fall-Pitt traps with drift fence"), were to analyze the feeding habits of Bothrops atrox in different locations, testing a correlation between diet and the composition of the venom of this species and also work with animals collected in areas with different land uses such as native forest, savannah and agricultural areas (pasture) in the region of Santarém, PA, Amazonia. with the use of traps and trapping fall (pit fall traps). Methods Selection of the Sampled areas For this study, samples taken from Bothrops atrox (B. atrox) in three areas with different vegetation cover: 1. Forest. Plateau Shoal Photo 2: Area conserved Photo 1: Preserved area 2. Savanna. 3. Agricultural land (pasture) Photo 3: Savanna, Tapari Photo 4: agricultural land (pasture)
