Resumo: | http://dx.doi.org/10.5902/198050985081This study aimed to characterize the floristic composition and structure of the tree component of a montane Araucaria Forest fragment and to assess the influence of environmental variables on the patterns observed. The study area was located in the municipality of Lages, Santa Catarina state, close to the margin of the Caveiras River. The vegetation and the environmental variables (physical and chemical soils characteristics, relief and canopy cover) were surveyed within 50, 20 x 10m, permanent plots allocated systematically stratified in the forest fragment. All trees with circumference at breast height (CBH) ³ 15,7 cm were measured (CBH and height) and identified. It was calculated the importance value (VI) of the species found, performed the ordination of plots according to the abundance of species through the analysis of NMDS (Nonmetric Multidimensional Scaling) and plotted the "a posterior" the significant environmental variables in the ordination diagram. One thousand, eight hundred and forty-three (1,843) individuals were sampled, which added up to a total basal area of 36.45 m2, distributed in 37 botanical families, 63 genera and 92 species. The three species with the highest values of VI were Araucaria angustifolia (Bertol.) Kuntze, Lithraea brasiliensis Marchand and Jacaranda puberula Cham. The variables that showed the higher correlation with the tree component structure and floristic composition were the pH, the plot highest declivity and the Mg content. |

A área de estudo situa-se no município de Lages, SC, às margens do Rio Caveiras (27°51'19.20"S e 50°10'33,39"W). O levantamento da vegetação e das variáveis ambientais (características químicas e físicas dos solos, relevo e cobertura do dossel) foi realizado em 50 parcelas permanentes de 20x10 m, alocadas de forma sistemática estratificada no fragmento. Todas as árvores vivas com circunferência ≥ 15,7 cm (medidas a 1,30 m do solo - CAP) foram mensuradas (CAP e altura) e identificadas. Foi calculado o valor de importância (VI) das espécies encontradas, realizada a ordenação das parcelas em função da abundância das espécies, por meio da analise de NMDS (Nonmetric multidimensional scalling) e plotadas a posteriori as variáveis ambientais significativas no diagrama de ordenação. Foram amostrados 1.843 indivíduos, que totalizaram uma área basal de 36,45 m2/ha, distribuídos em 37 famílias botânicas, 63 gêneros e 92 espécies. As três espécies com os maiores valores de VI foram Araucaria angustifolia (Bertol.) Kuntze, Lithraea brasiliensis Marchand e Jacaranda puberula Cham. As variáveis que apresentaram maior correlação com a estrutura e a composição florística do componente arbóreo foram o pH, o desnível máximo da parcela e o teor de Mg.Universidade Federal de Santa Maria2012-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/508110.5902/198050985081Ciência Florestal; Vol. 22 No. 1 (2012); 79-90Ciência Florestal; v. 22 n. 1 (2012); 79-901980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/5081/3074Higuchi, PedroSilva, Ana Carolina daFerreira, Tiago de SouzaSouza, Sheila Trierveiler deGomes, Juliano PereiraSilva, Karina Montibeller daSantos, Kristiana Fiorentin dosLinke, CarolinePaulino, Patrícia da Silvainfo:eu-repo/semantics/openAccess2014-08-28T22:47:39Zoai:ojs.pkp.sfu.ca:article/5081Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2014-08-28T22:47:39Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
