Popis: In small-scale human settlements, the acquisition of animal protein is strictly related to subsistence activities, and yours dietary habits are determined by the availability and the selectivity permitted by the diversity of these resources. This study analyzed the consumption of animal protein sources in seven traditional riverine communities of the Tapajos National Forest, located in Eastern Brazilian Amazonia, considering fish, game meat and domestic animals. The analysis of animal protein consumption was based on the assumptions of the diet breadth model and the Optimal Foraging Theory. We compared diet breadths between communities and between rainy and dry seasons. The study focused on seven traditional riverside communities, six of them distributed along the right bank of the Tapajos River and one on the right bank of the Cupari River. Data collection was performed in four fields trips, two in the rainy season (May and July) and two in the dry season (September and November) in 2010. Data were collected through semi-structured interviews where the informant mentioned the source of animal protein consumed in the last three meals and which would be consumed at the next meal, if possible. We carried out a total of 470 interviews, where we documented 1 512 meals, and in only 12% of the meals there was no consumption of any animal protein source. The fish was consumed in 60.4% of the meals, being the most important source of animal protein consumed, differing significantly from other protein sources (χ²=23.79, df=5, p
