Resumo: Assessing the effects of land use change on biodiversity has become a key issue for species conservation. Thus, it is necessary to analyze the configuration and composition of the landscape where a species occurs. The objective was to draw a profile of the forest remnants of the Atlantic Forest located in the south of Bahia state that present current and historical records of Crax blumenbachii. We analyzed fourteen areas using different spatial scales (patch scale, 500 m, 1 and 2 km) to calculate the total distance and distance from roads and rivers to the edge of the patch, percentage of area occupied by: forest, forest with cabrucas, cabrucas, pasture and agriculture; density of fragments and the proximity of these fragments to the edge of each patch, the area occupied by houses and their distance to the edge of the patch. We selected the 2 km scale to best describe the configuration and composition of the landscape. There are two profiles of areas with records of red-billed curassows: (1) areas with more forested landscapes, rivers and roads, low pasture/agriculture, and near human settlements, and (2) areas distant from houses, near roads and forest fragments. These features are related to areas with recent or historic records of red-billed curassows, and do not necessarily reflect habitat quality for the species.

Para isso, é necessário analisar a configuração e composição da paisagem em que determinada espécie ocorre. O objetivo foi traçar um perfil dos remanescentes florestais de Mata Atlântica localizados no sul da Bahia que apresentam registros atuais e históricos de Crax blumenbachii. Analisaram-se quatorze áreas utilizando diferentes escalas espaciais (escala de mancha, 500 m, 1 e 2 km) para calcular a quilometragem total e a distância mais próxima de estradas e rios até a borda da mancha, porcentagem de área ocupada por: floresta, floresta com cabrucas, pastagem e agricultura; densidade de fragmentos e a proximidade desses fragmentos até a borda de cada mancha, a área ocupada por casas e a distância dessas até a borda da mancha. Selecionou-se a escala de 2 km por melhor descrever a configuração e composição da paisagem. Há dois perfis de áreas com registros de mutum: (1) áreas com paisagens mais florestadas, com mais rios e estradas, pouca pastagem/agricultura e casas próximas, e (2) áreas distantes de casas, com estradas e fragmentos florestais próximos. Estas são caracteristicas de áreas com registros recentes ou históricos de mutum, e não necessariamente refletem qualidade de habitat para a espécie.Universidade Federal de Santa Maria2018-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3509910.5902/1980509835099Ciência Florestal; Vol. 28 No. 4 (2018); 1523-1533Ciência Florestal; v. 28 n. 4 (2018); 1523-15331980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/35099/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessRios, ElaineSantos, Poliane FariasBernardo, Christine Steiner São2018-12-16T20:33:04Zoai:ojs.pkp.sfu.ca:article/35099Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-12-16T20:33:04Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
