Resumo: This study aimed to test the hypothesis that different landscape elements, such as corridors, connected and non-connected forest fragments, have a tree component with floristic-structural differences. For this sake, the tree component of a fragment-corridor system was sampled by permanent plots (10 × 20 m), totaling an area of 1.4 ha. Within the plots, tree individuals with the circumference at breast height (cbh) greater than 15.7 cm, which botanical identities were determined in the field, were sampled and counted. The landscapes metrics (fragment size area, nearest neighbor distance and edge-interior relation) were extracted from a LANDSAT image, by FRAGSTAT software.  The organization and richness of the tree component in the landscape were analyzed through Non-Metric Multidimensional Scaling (NMDS), non-parametric multivariate variance analysis (NPMANOVA), Jaccard and Bray-Curtis dissimilarities indices, rarefaction, Venn diagram and indicator species analysis. Three non-connected fragments, two connected fragments and two forest corridors were recognized. In these landscape elements, a total of 84 species, 60 genera and 36 botanical families were found. The most floristically distinctive landscape element was the corridor. The hypothesis that the different landscape elements have a tree component with floristic-structural differences was accepted, supporting the idea that the spatial organization of forest fragments and corridors is relevant for the organization of tree vegetation in a landscape scale.

Para isto, o componente arbóreo de um sistema de fragmentos e corredores florestais foi amostrado por meio de 70 parcelas permanentes de 10 × 20 m, totalizando 1,4 ha amostrado. Dentro das parcelas, foram identificados e quantificados os indivíduos arbóreos com circunferência a altura do peito (CAP) maior ou igual a 15,7 cm. As métricas da paisagem (área, distância do vizinho mais próximo e relação borda interior) foram extraídas de imagem LANDSAT, por meio do programa FRAGSTAT. A organização e a riqueza do componente arbóreo na paisagem foram avaliadas por meio do Escalonamento Multidimensional Não métrico (NMDS), da análise de variância multivariada não paramétrica (NPMANOVA), dos índices de dissimilaridade de Jaccard e Bray-Curtis, da rarefação, do diagrama de Venn e análise de espécies indicadoras. Foram identificados três fragmentos não conectados, dois conectados e dois corredores florestais. Neles, foram observadas 84 espécies arbóreas, pertencentes a 60 gêneros e 36 famílias. O elemento da paisagem floristicamente mais distinto foi o corredor. A hipótese de que os diferentes elementos da paisagem apresentam o componente arbóreo com composição florístico-estrutural diferentes entre si foi aceita, reforçando a ideia de que a organização espacial de fragmentos e corredores florestais são relevantes na organização da vegetação arbórea em uma escala de paisagem.Universidade Federal de Santa Maria2018-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3206110.5902/1980509832061Ciência Florestal; Vol. 28 No. 2 (2018); 661-673Ciência Florestal; v. 28 n. 2 (2018); 661-6731980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/32061/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessHiguchi, PedroSilva, Ana Carolina daSpiazzi, Fábio RodriguesNegrini, MarceloRafaeli Neto, Silvio LuisBento, Marco AntonioMorés, Diego FelipeAguiar, Manoela Drews deBuzzi Junior, FernandoSilva, André Leonardo da2018-06-29T11:07:47Zoai:ojs.pkp.sfu.ca:article/32061Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-06-29T11:07:47Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
