SUMMARY:

Environmental heterogeneity has a significant contribution in the distribution and diversity of organisms, can also play a determining role in the composition, richness and abundance of many species. Medium and large terrestrial mammals =>1 kg in adulthood, perform important ecosystem services and ecological functions, whether in terms of seed dispersal, population management of species or structure and composition of the forest environment. The objective of this study was to estimate the richness, composition and relative abundance of species of the medium and large mammal community and hunting birds in three environments of the Ecotone Savanna and Ombrophilous Forest of the northern portion of the Mapinguari National Park/AM:. Data were obtained through photographic trapping using 120 Bushnell model 1139C traps, placed in the three environments simultaneously, where they remained for a minimum period of thirty days. Shanon, Simpson, Simpson-D, Chao, equitability of Pielou and Margalef indexes were used as indicators of diversity and dominance. It was possible to identify 29 species, 21 species of medium and large mammals and 08 species of hunting birds. There was a predominance of the Carnivora Order, which of the five families that occur in Brazil, four were represented during the study. The diversity indices generated from the collected data showed that the savanna/forest transition area reached the number of species expected for this environment and obtained greater equitability between species in relation to the other two environments. The Ombrophylous Forest environment presented five exclusive species: three of game birds Crypturellus cinereus (cinereous tinamou), Tinamus major (great tinamou), Psophia leucoptera (white-winged trumpeter) and two of mammals: Procyon cancrivorus (crab-eating raccoon) and Dasypus pastaae (greater-long-nosed-armadillo). The savannah environment presented two exclusive species: Rhynchotus rufescens (partridge) and Ozotoceros bezoarticus (Pampas deer), a species typical of open areas in central Brazil, but which has fragmented populations in some regions of the Amazon, such as PARNA Mapinguari and PARNA Campos Amazônicos. There were no species exclusive to the transition area. Therefore, this study showed that the Ombrófila forest environment has greater richness in relation to the others environments, however, the transition area presented lower dominance and greater equitability between species, evidencing the importance of heterogeneous environments for the community of mammals and hunting birds.
