Resumo: Although Maranhão State has the second longest coastline of Brazil, phytosociological studies are necessary to expand the knowledge of the restinga vegetation therein. Thus, the present study characterizes structural parameters of the woody component of a restinga in Alcântara city, west coast of Maranhão State. The phytosociological sampling included thirteen 100 m parallel transects, totaling 50 points. The inclusion criterion established for the species was perimeter at ground level ≥ 10 cm. We sampled 34 species, 26 genera, and 17 families, totaling 200 individuals. The species with the highest importance value (IV) were Guettarda angelica Mart. ex Müll.Arg., Anacardium occidentale L., Myrcia splendens (Sw.) DC., Cenostigma bracteosum (Tul.) E. Gagnon & G.P. Lewis, Fridericia sp., Eugenia stictopetala Mart. ex DC., and Mouriri guianensis Aubl. The average height of the specimens was 4.44 m, and the average diameter was 12.6 cm. The Shannon diversity index found in the restinga was 2.92 nat. ind-1, and Pielou’s evenness was 0.83. It is worth mentioning the presence of Sapium glandulosum (L.) Morong and Manilkara bidentata (A.DC.) A.Chev, which are common species of the Cerrado and the Amazonian forest, respectively. Our findings contribute to the knowledge of diversity, generating data for the development of conservation studies, besides reinforcing the influence of the flora of neighboring ecosystems in the colonization of the restingas of Maranhão State.

Assim, o presente estudo teve como objetivo caracterizar os parâmetros estruturais do componente lenhoso de uma restinga no município de Alcântara, Maranhão. Para a amostragem fitossociológica foram instalados 13 transectos de 100 m paralelos, totalizando 50 pontos com critério de inclusão de espécies foi o Perímetro à Altura do Solo ≥ 10 cm. Foram amostradas 34 espécies, 26 gêneros e 17 famílias, em um total de 200 indivíduos. As espécies de maior valor de importância foram Guettarda angelica Mart. ex Müll.Arg., Anacardium occidentale L., Myrcia splendens (Sw.) DC., Cenostigma bracteosum (Tul.) E. Gagnon & G.P. Lewis, Fridericia Mart. sp., Eugenia stictopetala Mart. ex DC. e Mouriri guianensis Aubl. A altura média dos espécimes foi de 4,44 m e o diâmetro médio foi de 12,6 cm. O índice de diversidade de Shannon foi de 2,92 nat. ind-1 e a equabilidade de 0,83. Cabe ressaltar a presença de Sapium glandulosum (L.) Morong e Manilkara bidentata (A.DC.) A.Chev., que são espécies comuns de áreas de Cerrado e de Floresta Amazônica, respectivamente. Os dados apresentados contribuem para o conhecimento da diversidade, gerando dados para o desenvolvimento de estudos direcionados a conservação, além de reforçar a influência da flora dos ecossistemas vizinhos na colonização das áreas de restinga do Maranhão.Universidade Federal de Campina Grande - UFCG2020-05-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/26110.22571/2526-4338261Acta Brasiliensis; Vol 4 No 2 (2020): Acta Brasiliensis; 85-90Acta Brasiliensis; Vol 4 No 2 (2020): Acta Brasiliensis; 85-90Acta Brasiliensis; Vol 4 No 2 (2020): Acta Brasiliensis; 85-902526-43382526-432Xreponame:Acta Brasiliensis (Online)instname:Universidade Federal de Campina Grande (UFCG)instacron:UFCGenghttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/261/91Copyright (c) 2019 Acta Brasiliensisinfo:eu-repo/semantics/openAccessAlmeida Júnior, Eduardo BezerraCorreia, Bruna Emanuele FreireSantos-Filho, Francisco Soares2021-07-12T20:03:41Zoai:ActaBra.revistas.ufcg.edu.br:article/261Revistahttp://revistas.ufcg.edu.br/ActaBraPUBhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/oaiactabrasiliensis@gmail.com || actabrasiliensis@gmail.com2526-432X2526-4338opendoar:2021-07-12T20:03:41Acta Brasiliensis (Online) - Universidade Federal de Campina Grande (UFCG)false
