Resumo: | The study aimed to understand the dynamic patterns of natural regeneration of shrub-tree species and determine whether these patterns are influenced by environmental variables, in three open areas in natural regeneration (diameter at breast height < 5 cm), in contact to upper montane Araucaria Forest fragments, located in the Southern Plateau of Santa Catarina state. Three 20x100 m transects, subdivided into sub-plots of 10x10 m, were installed in each area, perpendicular to the edge of the fragments with their length covering the grassland area. All shrub-tree regenerating individuals greater than or equal to 20 cm height were sampled. In each sub-plot, the environmental data were collected: soil physico-chemical properties, the degree of soil compaction and the altimetric quota. One year after the frst inventory, the dynamics rates were obtained for the three community and populations, and the found patterns related to environmental variables. The data were analyzed through Kruskal-Wallis tests, multiple comparison tests, chi-square test, applied to a contingency table, Principal Component Analysis (PCA) and linear mixed models. The results demonstrated that during the evaluated period, the natural regeneration process of the shrub-tree component is found in an early stage and it was characterized by abundance increment, richness stability, spatial independency between mortality and recruitment, and recruitment limitation in function of low soil natural fertility and high Al availability. |

Foram instaladas três transecções, uma por área, de 20x100 m, subdividas em sub-parcelas de 10x10 m, perpendiculares à borda dos fragmentos, com sua extensão cobrindo a área de campo. Amostraram-se todos os indivíduos regenerantes arbustivo-arbóreos com 20 cm ou mais de altura. Em cada sub-parcela, foram coletados os seguintes dados ambientais: propriedades físico-químicas dos solos, grau de compactação dos solos e topografia. Um ano após o inventário, foram obtidas as taxas de dinâmica para as três comunidades e para as populações, e os padrões encontrados foram relacionados com as variáveis ambientais. Os dados foram analisados por meio de testes de Kruskal-Wallis, testes de comparações múltiplas, teste de qui-quadrado aplicado a tabela de contingência, teste de correlação, Análise de Componentes Principais (PCA) e modelos lineares mistos. Os resultados demonstraram que no período estudado, o processo de regeneração natural do componente arbustivo-arbóreo encontra-se em fase inicial e foi caracterizado pelo incremento na abundância de indivíduos, estabilidade na riqueza, independência espacial entre a mortalidade e o recrutamento e limitação do recrutamento em função da baixa fertilidade natural do solo e elevada disponibilidade de Al.Universidade Federal de Santa Maria2019-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2599810.5902/1980509825998Ciência Florestal; Vol. 29 No. 1 (2019); 130-143Ciência Florestal; v. 29 n. 1 (2019); 130-1431980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/25998/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessDallabrida, Juliana PizuttiSilva, Ana CarolinaHiguchi, PedroLarsen, Janaina GabrielaSantos, Guilherme NetoLima, Carla LucianeRodrigues Júnior, Luiz CarlosMachado, Felipe DomingosCruz, Aline PereiraNunes, Amanda da Silva2020-06-05T19:47:21Zoai:ojs.pkp.sfu.ca:article/25998Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2020-06-05T19:47:21Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
