Resumo: | This study aimed to characterize the phytosociological structure of the mangrove in Roteiro Lagoon in the state of Alagoas, through phytosociological parameters. For that purpose, six transects were traced, divided into three 400 m² plots each, 10 meters apart each other. To check the abiotic factors, a thermometer (temperature) and a refractometer (salinity) were used. Three sediment samples were also collected, at a depth of 20 cm, for the granulometry and organic matter analyses. A total of 449 trees were measured, showing trees Rhizophora mangle, Laguncularia racemosa and Avicennia schaueriana. The average density of the arboreal vegetation was 624 ind.ha-1, with the Rhizophora mangle species showing the highest phytosociological indexes, with a value of 220.59%. The values of the phytosociological parameters showed great amplitude in the analyzed plots, occurring from seedlings to adult trees. The temperature values did not show significant differences between the average of the fringe, intermediate and interior portion, however, the salinity stood out, showing an increase in relation to the interior of the forest. There was a predominance of sandy silt in the studied mangrove forest. Thus, the phytosociological analysis revealed high structural diversity, in an environment where the abiotic factors contribute to the establishment of tree species and a high contribution of the Rhizophora mangle species in all phytosociological parameters assessed in the ecosystem. |

Para isso, foram traçados seis transectos, cada um dividido em três parcelas de 400 m², distanciadas 10 metros entre si. Para a verificação dos fatores abióticos foram utilizados termômetro (temperatura) e refratômetro (salinidade). Foram coletadas ainda três amostras de sedimento, a uma profundidade de 20 cm, para a análise da granulometria e matéria orgânica. Foram mensuradas 449 árvores, apresentando árvores de Rhizophora mangle, Laguncularia racemosa e Avicennia schaueriana. A densidade média da vegetação arbórea foi de 624 ind.ha-1, sendo a espécie Rhizophora mangle a que apresentou os maiores índices fitossociológicos, com valor de importância de 220,59%. Os valores dos parâmetros fitossociológicos apresentaram grande amplitude nas parcelas analisadas, ocorrendo desde plântulas até árvores adultas. Os valores de temperatura não apresentaram diferenças significativas entre as médias das parcelas franja, intermediária e interior, porém a salinidade se destacou, apresentando um aumento em relação ao interior do bosque. Houve predominância de sedimento areno-lodoso no manguezal estudado. Dessa maneira, a análise fitossociológica revelou elevada diversidade estrutural, em um ambiente onde os fatores abióticos contribuem para o estabelecimento das espécies arbóreas, e uma elevada contribuição da espécie Rhizophora mangle em todos os parâmetros fitossociológicos avaliados no ecossistema.Universidade Federal de Santa Maria2020-06-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3967610.5902/1980509839676Ciência Florestal; Vol. 30 No. 2 (2020); 532-541Ciência Florestal; v. 30 n. 2 (2020); 532-5411980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/39676/39676Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessSilva, Simony AndradeBarros, Vitória Petra de OliveiraOliveira, Alexandre Ricardo de2021-05-20T04:00:47Zoai:ojs.pkp.sfu.ca:article/39676Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:47Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
