- Accessibility do not explain abundance of medium and large-sized mammals in Terra Do Meio, Altamira, Pará, Brazil Roberto Portella De Andrade Rodolfo Salm Isadora França Emil José Hernandéz Ruz Biología Hunting mastofauna conservation Eastern Amazon environmental disturbance The aim of this study was to evaluate the effects of accessibility on hunting pressure by considering the mammal abundance and biomass of two protected areas belonging to different conservation categories -indigenous land and Ecological Station- in the Xingu River basin, eastern Amazon. For doing so, we used linear transection methods (total effort 240 km, in four tracks), camera traps (487 days) and complementary records. We also developed an accessibility coefficient based on the distance between navigable rivers and roads, and the center point of the sampled trails. We used the Simple linear regression test to analyze the effects of this accessibility on the biomass of the sighted species, gathering them in orders. We found 34 species belonging to seven families and six orders. We found no relation between mammal biomass and our accessibility index, which suggests that hunting pressure affects even the most distant studied areas. 2019 artículo científico 0065-1737 https://www.redalyc.org/articulo.oa?id=57560444010 https://www.redalyc.org/journal/575/57560444010/ https://www.redalyc.org/journal/575/57560444010/html/ https://www.redalyc.org/journal/575/57560444010/57560444010.epub https://www.redalyc.org/journal/575/57560444010/movil 10.21829/azm.2019.3501219 en http://www.redalyc.org/revista.oa?id=575 Acta Zoológica Mexicana (nueva serie) application/pdf Instituto de Ecología, A.C.
