Accessibility do not explain abundance of medium and large-sized mammals in Terra Do Meio, Altamira, Pará, Brazil
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.

| description | 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. |

Nosso objetivo foi analisar os efeitos da acessibilidade sobre a pressão de caça refletida na abundância e biomassa de mamíferos em duas áreas protegidas de diferentes categorias de conservação. Terra indígena e Estação Ecológica, na bacia do rio Xingu, no leste da Amazônia. Para tal, usamos os métodos de transição linear (esforço de 240 km), armadilhas fotográficas (487 dias) e registros complementares. Adicionalmente, desenvolvemos um coeficiente de acessibilidade com base na distância dos rios e estradas navegáveis para o ponto central das trilhas percorridas. Utilizamos regressão linear simples para analisar os efeitos da acessibilidade sobre a biomassa das espécies avistadas (agrupadas em ordens). Encontramos 34 espécies pertencentes a 07 famílias. Não encontramos relação entre a biomassa de mamíferos e nosso índice de acessibilidade, sugerindo que a pressão de caça afeta a área estudada a uma maior distância.
