Resumo: The objective of this work was to evaluate the floristic and phytosociological composition of a Cerrado lato sensu fragment. A census was carried out in the study area, of 6.7 ha, with inclusion limit of 15 cm of circumference at 1.30 m above ground level. We registered 15,434 individuals, from 78 species, 72 genera and 33 families. Density, dominance and cover value were analyzed, with a total density of 2,303.58 ind ha-1 and a basal area of 94.303 m² ha-1. The species with the highest cover values, in descending order, were Myrcia splendens, Astronium fraxinifolium, Magonia pubescens, Qualea parviflora, Protium heptaphyllum, Curatella americana, Vatairea macrocarpa, Tachigali aurea, Byrsonima stipulacea and Machaerium brasiliense, which represented 53% of all individuals of the area. Species of the genus Qualea presented dominance, representing 11% of the total of individuals. The distribution pattern of the individuals was inverted “J” format, but Astronium fraxinifolium, Magonia pubescens and Tachigali aurea presented lower number of individuals in the initial classes. The Shannon diversity index and the Pielou equability indicated the existence of high species richness and diversity when comparing the studied area with Cerrado fragments nearby.

Foi realizado um censo na área de estudo, de 6,7 ha, com limite de inclusão de 15 cm de circunferência a 1,30 m acima do solo. Amostrou-se um total de 15.434 indivíduos, pertencentes a 78 espécies, 72 gêneros e 33 famílias. Foi realizada análise de densidade, dominância e valor de cobertura, encontrando-se densidade total de 2.303,58 ind ha-1 e área basal de 94,303 m² ha-1. As espécies com maiores valores de cobertura, em ordem decrescente, foram: Myrcia splendens, Astronium fraxinifolium, Magonia pubescens, Qualea parviflora, Protium heptaphyllum, Curatella americana, Vatairea macrocarpa, Tachigali aurea, Byrsonima stipulacea e Machaerium brasiliense, que representaram 53% do total dos indivíduos da área. As espécies do gênero Qualea apresentaram dominância, representando 11% do total de indivíduos. O padrão de distribuição dos indivíduos foi no formato de “J” invertido, mas Astronium fraxinifolium, Magonia pubescens e Tachigali aurea apresentaram menor número de indivíduo nas classes iniciais. O índice de diversidade de Shannon e equabilidade de Pielou indicaram a existência de alta riqueza e diversidade de espécies, quando se comparou a área estudada com fragmentos de Cerrado nas proximidades.Embrapa Florestas2019-06-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/168510.4336/2019.pfb.39e201801685Pesquisa Florestal Brasileira; v. 39 (2019)Pesquisa Florestal Brasileira; Vol. 39 (2019)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1685/894https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMachado, Igor Eloi SilvaTavares, Maíra Elisa FerreiraMedeiros, Paulo César Alves de OliveiraGiongo, MarcosSouza, Priscila Bezerra deBatista, Antonio Carlos2019-12-31T20:35:26Zoai:pfb.cnpf.embrapa.br/pfb:article/1685Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2019-12-31T20:35:26Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
