Resumo: | The dynamics of adult and regenerative tree species components was assessed in a cloud forest in the South Plateau of Santa Catarina state, southern Brazil, seeking a better understanding of the process of vegetation development. To this end, permanent sampling plots were allocated, where the adult and regenerative components were characterized, respectively, in 2011 and 2013. All surveyed species were classified according to regeneration guilds into pioneer, light-demanding climax, and shade-tolerant climax. In 2015, a second tree species component survey was conducted to determine the growth of surviving individuals (adults) and count the recruited and dead individuals. For each population, the net change rates for individuals (adults and regenerative) and basal area (only adults) were determined. Proportion tests were conducted to verify whether representativeness of the regeneration guilds changed over the study period. The results showed that the forest investigated is undergoing a structuring process characterized by gains in number of individuals and basal area. In contrast, stability in species richness and representativeness of regeneration guilds was verified, with highlight for light-demanding climax species. In conclusion, the assessed forest is undergoing a structuring phase that favors the regeneration of light-demanding species. |

Para isso, foram instaladas parcelas permanentes onde foram caracterizados os componentes adulto e regenerante, respectivamente, nos anos de 2011 e 2013. Todas as espécies amostradas foram classificadas quanto à guilda de regeneração em pioneiras, climácicas exigentes em luz e climácicas tolerantes ao sombreamemto. No ano de 2015, foi realizado o segundo inventário dos componentes vegetacionais, sendo determinado o crescimento dos sobreviventes (somente adultos) e contabilizados os indivíduos recrutados e mortos. Para cada uma das populações, foram determinadas as taxas de mudança líquida em número de indivíduos (adultos e regenerantes) e em área basal (adultos). Foram realizados testes de proporções para verificar se a representatividade das diferentes guildas de regeneração se alterou entre os anos avaliados. Os resultados indicaram que a floresta se encontra em um processo de estruturação, caracterizado pelo ganho em número de indivíduos e em área basal. Por outro lado, observou-se estabilidade na riqueza e na representatividade das guildas de regeneração, com destaque para a maior participação de espécies classificadas como clímax exigentes em luz. Conclui-se que a floresta avaliada se encontra em estruturação, com o favorecimento da regeneração de espécies exigentes em luz.Universidade Federal de Santa Maria2021-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2965410.5902/1980509829654Ciência Florestal; Vol. 31 No. 3 (2021); 1086-1104Ciência Florestal; v. 31 n. 3 (2021); 1086-11041980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/29654/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/29654/htmlCopyright (c) 2021 Ciência Florestalinfo:eu-repo/semantics/openAccessNeto Santos, GuilhermeSilva, Ana Carolina daHiguchi, PedroGross, AlineKilca, Ricardo de VargasSilva, Mariele Alves FerrerLima, Carla LucianeCruz, Aline PereiraNunes, Amanda da SilvaSoboleski, Vanessa Fátima2021-09-06T21:13:38Zoai:ojs.pkp.sfu.ca:article/29654Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-09-06T21:13:38Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |

The dynamics of adult and regenerative tree species components was assessed in a cloud forest in the South Plateau of Santa Catarina state, southern Brazil, seeking a better understanding of the process of vegetation development. To this end, permanent sampling plots were allocated, where the adult and regenerative components were characterized, respectively, in 2011 and 2013. All surveyed species were classified according to regeneration guilds into pioneer, light-demanding climax, and shade-tolerant climax. In 2015, a second tree species component survey was conducted to determine the growth of surviving individuals (adults) and count the recruited and dead individuals. For each population, the net change rates for individuals (adults and regenerative) and basal area (only adults) were determined. Proportion tests were conducted to verify whether representativeness of the regeneration guilds changed over the study period. The results showed that the forest investigated is undergoing a structuring process characterized by gains in number of individuals and basal area. In contrast, stability in species richness and representativeness of regeneration guilds was verified, with highlight for light-demanding climax species. In conclusion, the assessed forest is undergoing a structuring phase that favors the regeneration of light-demanding species. |
