Resumo: http://dx.doi.org/10.5902/1980509817465This study aims to identify structural similarities between the remnants of seasonal deciduous forest (SDF) in Santa Catarina state and check the influence of environmental factors that leads the formation of these groups. Associated with this primary objective, it was also sought to identify the areas of contact between this forest type and Araucaria forest (mixed ombrophilous forest – MOF). We analyzed data from 78 sample units (AU) installed in the remnants of SDF between 2008 and 2009 by professional team of Floristic and Forest Inventory of Santa Catarina project (IFFSC). The data were processed through the Detrended Correspondence Analysis (DCA) and Canonical Correspondence Analysis (CCA), using a matrix of species density associated with a environmental variables matrix, that consisted of altitude and climate parameters. The proportion of variance explained by the first three axes of DCA was low, accounting for approximately 21% of the information contained in the original data set. This result provides low power of interpretation of the results. However, when DCA was applied to the data of mean density of species in each river basin, the results pointed to better explanatory eigenvectors (three first eigenvectors explain 58.1% of total variance). The first ordination axis of DCA grouped the eastern watersheds SUs at one end, and the western watersheds SUs at the other end of this axis. At the right end of the first axis are arranged the watersheds of the river Canoas, Pelotas and Peixe, which are characterized by the presence of species such as Ocotea pulchella, Zanthoxylum fagara, Lithrea brasiliensis, Matayba elaeagnoides, Cinnamodendron dinisii commonly associated with Mixed Ombrophilous Forest (Araucaria forest). At the left end, the grouped SUs are mainly those of western watersheds, a group that includes the basins of the Jacutinga, Irani, Chapecó, Antas and Peperi-guaçu rivers. Among the species that most strongly influence the results in the analysis, we highlight Apuleia leiocarpa, Rauvolfia sellowii, Bastardiopsis densiflora, Chrysophyllum gonocarpum, Cordia trichotoma, Holocalyx balansae, Myrocarpus frondosus and Pisonia zapallo, which are common in seasonal forests of the hinterlands of southern Brazil. The analysis through the ACC pointed to similar results and joint interpretation of environmental data indicated that the basins located in the east are associated with colder climates where frosts are more frequent as a result of higher altitudes. As the altitudes tend to decline from east to west and portions, the authors propose the existence of a transition zone between the two phytoecological regions (MOF and SDF) in the range of 600 m asl, where occurs the interdigitation of elements from seasonal flora and those of Araucaria forest, resulting in the delineation of a core area of the SDF below this altitudinal level.

Associado a este objetivo primário, também se buscou a identificação das zonas de contato entre esta tipologia florestal e a Floresta Ombrófila Mista (FOM). Foram analisados os dados de 78 unidades amostrais (UA) instaladas em remanescentes da FED entre 2008 e 2009 pelo Inventário Florístico Florestal de Santa Catarina (IFFSC). Os dados foram tratados através da Análise de Correspondência Corrigida (DCA) e da Análise de Correspondência Canônica (ACC), valendo-se de uma matriz de densidade de espécies e uma matriz de variáveis ambientais, esta constituída por altitude e parâmetros climáticos. A proporção da variância explicada pelos três primeiros eixos da DCA foi baixa, somando aproximadamente 21% do total de informação contida no conjunto original de dados. Este resultado ofereceu baixo poder de interpretação para os resultados. No entanto, quando a DCA foi aplicada sobre os dados de densidade média das espécies em cada bacia hidrográfica, os resultados apontaram para autovetores muito explicativos do conjunto (58,1% da variação). Observada somente a ordenação provocada pelo primeiro eixo da DCA, vê-se a disposição das bacias de leste, em um extremo, e das bacias de oeste, no outro extremo deste eixo. Na extremidade direita do primeiro eixo estão dispostas as bacias do rio Canoas, Pelotas e do Peixe, as quais são caracterizadas pela presença de espécies como Ocotea pulchella, Zanthoxylum fagara, Lithrea brasiliensis, Matayba elaeagnoides, Cinnamodendron dinisii, comumente associadas com a Floresta Ombrófila Mista. Na extremidade esquerda estão distribuídas as bacias de oeste, grupo que inclui as bacias dos rios Jacutinga, Irani, Chapecó, Antas e Peperi-Guaçu. Dentre as espécies que mais fortemente influenciaram os resultados na análise, cabe destacar Apuleia leiocarpa, Rauvolfia sellowii, Bastardiopsis densiflora, Chrysophyllum gonocarpum, Cordia trichotoma, Holocalyx balansae, Myrocarpus frondosus e Pisonia zapallo, as quais são frequentes em florestas estacionais do interior meridional do Brasil. A análise através da ACC apontou para resultados similares e a interpretação conjunta dos dados ambientais indicou que as UA situadas nas bacias de leste estão associadas a climas mais frios, em que as geadas são mais frequentes, como consequência de altitudes mais elevadas. Considerando que as altitudes tendem a declinar das porções lestes para oeste e, diante do resultados apresentados, os autores propõem a existência de uma zona de transição entre as duas regiões fitoecológicas (FOM e FED) na faixa dos 600 m s.n.m., onde ocorre a interdigitação de elementos da flora estacional e aqueles da Floresta Ombrófila Mista, resultando na delimitação de uma área core da FED abaixo deste patamar altimétrico. Universidade Federal de Santa Maria2015-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1746510.5902/1980509817465Ciência Florestal; Vol. 25 No. 1 (2015); 77-89Ciência Florestal; v. 25 n. 1 (2015); 77-891980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/17465/pdf_1Gasper, André Luís deUhlmann, AlexandreVibrans, Alexander ChristianSevegnani, Luciainfo:eu-repo/semantics/openAccess2017-04-11T17:10:58Zoai:ojs.pkp.sfu.ca:article/17465Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-11T17:10:58Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
