Resumo: | Comparative studies between different strata of forests in ecological succession are important to understand the forest dynamics. The study evaluated floristic, phytosociological and ecological aspects between the tree and regenerating strata of an urban fragment of semideciduous forest, in Jataí, Goiás state. In the last decades, the vegetation that was typically savanna has become a forest. Trees (diameter at breast height, DBH ≥ 5 cm) were sampled in 12 permanent 200m² plots. In each of them, 25m² sub-plots were sampled for the regenerant stratum, which comprised individuals with DBH <5cm and height ≥ 1m. Regenerants had greater richness (31 species), with two more species than adults. There was low floristic and structural similarity between the strata, indicating a replacement of species over time. Shannon's diversity was significantly lower for the tree stratum (t test), since it presented low equability, with ecological dominance of few species. Both strata had a high proportion of pioneer species, when compared to other studies. Zoochory and species of forest environments were significantly more abundant in the regenerating stratum. The study revealed a fragment in a frank process of secondary succession and vulnerability in the face of anthropic pressures, with care regarding its conservation being important. |

O estudo avaliou aspectos florísticos, fitossociológicos e ecológicos entre os estratos adulto e regenerante de um fragmento urbano de floresta estacional semidecidual, em Jataí, Goiás. Nas últimas décadas, a vegetação que era tipicamente savânica tem se tornado uma floresta. As árvores adultas (diâmetro a altura do peito, DAP ≥ 5 cm) foram amostradas em 12 parcelas permanentes de 200m². Em cada uma delas, sub-parcelas de 25m² foram amostradas para o estrato regenerante, que compreendeu indivíduos com DAP < 5cm e altura ≥ 1m. Regenerantes tiveram maior riqueza (31 espécies), com duas espécies a mais do que os adultos. Houve baixa similaridade florística e estrutural entre os estratos, indicando uma substituição de espécies ao longo do tempo. A diversidade de Shannon foi significativamente menor para o estrato arbóreo (teste t), visto que apresentou baixa equabilidade, com dominância ecológica de poucas espécies. Ambos os estratos tiveram elevada proporção de espécies pioneiras, quando comparado com outros estudos. Zoocoria e espécies de ambientes florestais foram expressivamente mais abundantes no estrato regenerante. O estudo revelou um fragmento em franco processo de sucessão secundária e vulnerabilidade diante de pressões antrópicas, sendo importante os cuidados quanto à sua conservação.Universidade Federal de Santa Maria2021-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4786810.5902/1980509847868Ciência Florestal; Vol. 31 No. 1 (2021); 456-474Ciência Florestal; v. 31 n. 1 (2021); 456-4741980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/cienciaflorestal/article/view/47868/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/47868/htmlCopyright (c) 2021 Ciência Florestalinfo:eu-repo/semantics/openAccessGuilherme, Frederico Augusto GuimarãesFerreira, Wendy CarnielloSilva, Gabriel EliseuMachado, Deivid Lopes2021-05-20T04:00:56Zoai:ojs.pkp.sfu.ca:article/47868Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:56Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
