Resumo: | http://dx.doi.org/10.5902/1980509813317This study aimed to describe the tree component structure of two patches of Evergreen Seasonal Forest in Pacas River Basin in Querência municipality in Mato Grosso state, Brazil. The point-centered quarter method was applied to systematically distribute 200 points in pristine forest and 100 points in managed forest. In each quarter, the nearest tree to the sampling point with diameter at breast height equal or greater than 10 cm was included. Estimates of local species richness were obtained with the Jackknife 1 and the Jaccard index was used to determinate floristic similarity between the patches. Although the two forest patches have had distinct historical uses, with tree component structure distinct, the areas presented high floristic similarity (Cj=0.67), the local species richness was alike (57 species in pristine forest and 52 in managed forest) and the species with the highest importance value was the same in the both patches - Ocotea leucoxylon (Sw.) Laness. Despite the anthropogenic disturbances in the past, it is possible to conclude that the managed forest is in an advanced stage of regeneration as expected for the evergreen seasonal forests pattern since this forest is naturally less diverse than the Amazon ombrophilous forests. |

Foram distribuídos sistematicamente 200 pontos-quadrante em área preservada e 100 pontos em área alterada. Em cada ponto-quadrante foram medidos e identificados os quatro indivíduos mais próximos do ponto, adotando-se como critério de inclusão o diâmetro na altura de 1,30 m do solo ≥ 10 cm. Utilizou-se o estimador Jackknife 1 para estimar a riqueza específica e o índice de Jaccard para a similaridade florística entre os dois trechos. Embora os dois trechos apresentem históricos de alteração e preservação diferentes, com perfis fitossociológicos distintos, a similaridade florística entre eles foi alta (Cj=0,67), a riqueza específica foi similar (57 espécies na floresta preservada e 52 na alterada) e a espécie com maior Valor de Importância (VI) foi a mesma nos dois trechos - Ocotea leucoxylon (Sw.) Laness. Portanto, conclui-se que, apesar das alterações antrópicas sofridas no passado, o trecho de floresta alterado encontra-se em estágio avançado de regeneração para os padrões das florestas estacionais perenifólias, naturalmente menos diversas que as florestas ombrófilas amazônicas.Universidade Federal de Santa Maria2014-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1331710.5902/1980509813317Ciência Florestal; Vol. 24 No. 1 (2014); 1-11Ciência Florestal; v. 24 n. 1 (2014); 1-111980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/13317/pdf_1Kunz, Sustanis HornIvanauskas, Natália MacedoMartins, Sebastião VenâncioStefanello, DanielSilva, Eliasinfo:eu-repo/semantics/openAccess2017-04-13T17:02:22Zoai:ojs.pkp.sfu.ca:article/13317Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-13T17:02:22Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
