Resumo: | The replacement of native species by invasive species has caused a worldwide loss of biodiversity. This study aimed to evaluate the natural regeneration over time in a forest fragment invaded by Ligustrum lucidum W.T. Aiton and Ligustrum sinense Lour. in southern Brazil, in order to quantify this invasion. To do so, five transects were allocated in a fragment of Araucaria Forest in Lages, Santa Catarina state, with each transect divided into plots in different categories of distance from the edge and into sub-plots for the evaluation of the regenerative component. In 2012, the regenerating tree species identified in the sub-plots were tagged and classified according to height classes: Class 1, plants with height between 10 cm and 1 m; class 2, plants with height between 1 and 3 m; and Class 3, plants with a height greater than 3 m and DBH (diameter measured at breast height) less than 5 cm. In 2014, these individuals were re-evaluated, counting the dead and recruited individuals and classifying the survivors and recruits into the existing height classes. Rates of mortality, recruitment, net change, and height class changes were calculated. The data were analyzed by a Principal Component Analysis (PCA) and contingency table. It was concluded that the species overcame the early stage of the invasion process, demonstrating great population growth in the study area. Also, a spatial partitioning between native and exotic species was observed, suggesting the existence of interspecific competition, the result of which may be the local extinction of species from the autochthonous group. |

O presente estudo objetivou avaliar a regeneração natural ao longo do tempo em um fragmento florestal invadido por Ligustrum lucidum W.T. Aiton e Ligustrum sinense Lour. no sul do Brasil, a fim de quantificar essa invasão. Para isso, foram alocadas cinco transecções em um fragmento de Floresta Ombrófila Mista em Lages (SC), sendo cada transecção dividida em parcelas com diferentes setores de distâncias da borda e em subparcelas para avaliação do componente regenerativo. Em 2012, os regenerantes de espécies arbóreas que se encontravam nas subparcelas foram identificados, plaqueteados e divididos nas seguintes classes: classe 1 _ plantas com altura entre 10 cm e 1 m; classe 2 _ plantas com altura entre 1 e 3 m; classe 3 _ plantas com altura maior que 3 m e diâmetro medido à altura do peito (DAP) menor que 5 cm. Em 2014, esses indivíduos foram reavaliados, contabilizando os indivíduos mortos e recrutas e enquadrando os sobreviventes e recrutas nas atuais classes. Foram calculadas as taxas de mortalidade, recrutamento, mudanças de classe e mudança líquida. Os dados foram analisados por meio de uma análise de componentes principais (ACP) e tabela de contingência. Conclui-se que as espécies superaram a fase inicial do processo de invasão, demonstrando elevado incremento populacional na área estudada. Ainda, ficou evidenciado o particionamento espacial entre as espécies nativas e as exóticas, o que sugere a existência de competição interespecífica, cuja consequência pode ser a extinção local de representantes do grupo autóctone.Universidade Federal de Santa Maria2020-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2071810.5902/1980509820718Ciência Florestal; Vol. 30 No. 3 (2020); 620-631Ciência Florestal; v. 30 n. 3 (2020); 620-6311980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/20718/33570Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessNunes, Amanda da SilvaHiguchi, PedroSilva, Ana Carolina daKilca, Ricardo de VargasSilva, Mariele Alves Ferrer daRosa, Angélica DallaSoboleski, Vanessa FátimaDallabrida, Juliana PizuttiSouza, KarineCruz, Aline PereiraLima, Carla LucianeStedille, Lilian Iara BetLemos, Angela Camila2020-09-02T20:52:04Zoai:ojs.pkp.sfu.ca:article/20718Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2020-09-02T20:52:04Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
