Resumo: | The present study aimed to verify the relationships between tree species organization and environmental variables in a fragment of Araucaria Forest. To do so, in the locality of Coxilha Rica, in the region called “Planalto Sul Catarinense” region, a total of 50 plots of 200 m2 were allocated in a forest fragment, where all living trees with CAP (circumference at breast height, measured at 1.30 m above ground) greater than or equal to 15.7 cm were sampled, measured and identified. Environmental variables related to the terrain, canopy cover and soil chemical and physical properties were obtained for each plot. Phytosociological estimators were calculated and the plots ordinated in function of species abundance by NMDS analyze (Nonmetric multidimensional scalling). Then, the environmental variables were fitted to the produced ordination, being those significant variables (p ≤ 0.01) plotted as vectors. A total of 1,447 individuals, distributed in 69 species were sampled. Myrcia guianensis (Aubl.) DC. was the most relative important species (10.43% of IV). Drimys brasiliensis Miers stood out in steeper areas, with higher elevation and with less fertile soils, with greater values of OM, Al and Na. Sebastiania commersoniana (Baill.) LB Sm & Downs and others stood out in flat areas, with more fertile soils and low content of OM, Al and Na. We concluded that terrain and soil chemical properties represent an important source of floristic-structural heterogeneity in the study fragment. |

Para isso, na localidade da Coxilha Rica, no planalto sul catarinense, foram alocadas 50 parcelas de 200 m2 em um fragmento florestal, no qual foram amostrados, medidos (circunferência a altura peito, CAP) e identificados todos os indivíduos arbóreos vivos que apresentaram CAP igual ou superior a 15,7 cm. Em cada parcela, foram obtidas as variáveis ambientais: topografia, cobertura do dossel e características químicas e físicas dos solos. Foram calculados os estimadores fitossociológicos e ordenadas as parcelas em função da abundância das espécies, por meio da análise NMDS (Nonmetric multidimensional scalling). Em seguida, foi realizado ajuste entre a ordenação produzida e as variáveis ambientais, com as variáveis significativas (p ≤ 0,01) plotadas na forma de vetores. Foram amostrados 1.447 indivíduos, distribuídos em 69 espécies. Myrcia guianensis (Aubl.) DC. foi a espécie de maior valor de importância (VI=10,43%). Nas áreas com terreno mais declivoso, com maiores cotas altimétricas médias e com solos menos férteis, com maiores teores de MO, Al e Na, destacou-se a presença, entre outras espécies, de Drimys brasiliensis Miers. Nas áreas com o terreno mais plano e solos com maior fertilidade e menores teores de MO, Al e Na, foi comum Sebastiania commersoniana (Baill.) L.B. Sm. & Downs. Conclui-se que a topografia e as características químicas dos solos foram determinantes para a heterogeneidade florístico-estrutural no fragmento estudado.Universidade Federal de Santa Maria2016-12-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2511110.5902/1980509825111Ciência Florestal; Vol. 26 No. 4 (2016); 1201-1210Ciência Florestal; v. 26 n. 4 (2016); 1201-12101980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/25111/pdfCopyright (c) 2016 Ciência Florestalinfo:eu-repo/semantics/openAccessAnsolin, Roni Djeisonda Silva, Ana CarolinaHiguchi, PedroKüster, Larissa CardosoFerreira, Tiago de SouzaBuzzi Júnior, FernandoBento, Marco Antôniode Aguiar, Manoela DrewsCruz, Aline Pereira2017-04-05T17:39:42Zoai:ojs.pkp.sfu.ca:article/25111Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-05T17:39:42Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
