Resumo: The study aimed to describe the floristic composition and structure and life forms to lower stratum in a alluvial dense rain forest in the Environmental Protection Area of Combu Island, Belém, Pará state. Four plots were selected from 20 m x 20 m (0.16 ha) divided into 1.289 subplots of 1 m². The size category and the life forms of the species were classified. Density, frequency, size category and natural regeneration relative were calculated. The difference in abundance, richness, Shannon index and evenness between categories was tested using ANOVA. All 33 families were found, 63 genera, 79 species and 26,885 individuals. Fabaceae, Araceae, Arecaceae, Acanthaceae and Meliaceae had higher richness. The Shannon index and Evenness were 2.63 and 0.60, respectively for the total area. Pariana campestris and Anthurium sinuatum showed higher density, size category and natural regeneration relative. Herb showed the highest percentage of individuals and natural relative regeneration and tree richest. CT1 (15 cm ≥ AT) was different from the other categories, with lower abundance and richness. It is concluded that the herb dominance in percentage of individuals and natural relative regeneration and the lower abundance and richness in CT1 is a consequence of the anthropic activities carried out such as the intensive management of açaí palm (Euterpe oleracea Mart.) In the vicinity of the inventoried areas.

Foram selecionadas quatro parcelas de 20 m x 20 m (0,16 ha) divididas em 1.289 subparcelas de 1 m². Foi classificada a categoria de tamanho e a forma de vida das espécies. Calculou-se a densidade, frequência, categoria de tamanho e regeneração natural relativa. A diferença de abundância, riqueza, índice de Shannon e equabilidade entre as categorias foi testada com ANOVA. Foram amostradas 33 famílias, 63 gêneros, 79 espécies e 26.885 indivíduos. Fabaceae, Araceae, Arecaceae, Acanthaceae e Meliaceae apresentaram maior riqueza. O Índice de Shannon e Equabilidade foram de 2,63 e 0,60, respectivamente para a área total. Pariana campestris e Anthurium sinuatum apresentaram maior densidade, categoria de tamanho e regeneração natural relativa. As herbáceas apresentaram maior porcentagem de indivíduos e regeneração natural relativa e as árvores a maior riqueza. CT1 (15 cm ≥ AT) foi diferente das demais categorias, apresentando menor abundância e riqueza. Conclui-se que a dominância de herbáceas em porcentagem de indivíduos e regeneração natural relativa e a menor abundância e riqueza na CT1 é consequência das atividades antrópicas realizadas como o manejo intensivo da palmeira-açaí (Euterpe oleracea Mart.) nas proximidades das áreas inventariadas.Universidade Federal de Santa Maria2019-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2183410.5902/1980509821834Ciência Florestal; Vol. 29 No. 3 (2019); 1048-1059Ciência Florestal; v. 29 n. 3 (2019); 1048-10591980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/21834/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessBraga, Elayne OliveiraJardim, Mário Augusto Gonçalves2019-10-01T13:06:32Zoai:ojs.pkp.sfu.ca:article/21834Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-10-01T13:06:32Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
