Resumo: | The fragmentation of habitats has several ecosystem impacts. The high response of vegetation to environmental changes makes it a good indicator of biodiversity conservation condition. This work evaluated the conservation of a Cerradão fragment in the Cáceres municipality, Mato Grosso State, by analyzing the horizontal structure and diversity of species of the tree-shrub layer. The survey was based on two randomized conglomerates, totaling 8 plots and 0.8 ha. The criterion included was the diameter at 1.30 m above ground level ≥ 10 cm. A total of 411 individuals, 44 species and 21 botanical families were sampled. The families Fabaceae and Bignoniaceae presented the greatest species richness. The values of the Shannon-Weaver diversity and the Pielou Equability indices were considered high (3.18 and 0.84, respectively). The floristic similarity between the conglomerates was high, (Sørensen Index = 74.63%), indicating that the fragment is homogeneous. We observed inverted-J shape diametric distribution. The community presented an aggregate tendency, with an average Payandeh Aggregation index equal to 1.40. The richness and phytosociology indicated good conservation of the tree-shrub layer, as there were no floristic-structural changes in the fragment due to the anthropic activities surrounding the area. |

A resposta da vegetação às mudanças ambientais a tornam um bom indicador do estado de conservação da biodiversidade. O objetivo deste trabalho foi avaliar a conservação de um fragmento de Cerradão no município de Cáceres, MT, pela análise da estrutura horizontal e da diversidade de espécies do estrato arbóreo-arbustivo. O levantamento foi baseado em dois conglomerados aleatorizados, totalizando 8 parcelas em 0,8 ha. O critério de inclusão foi o diâmetro a 1,30 m do solo ≥ 10 cm. Foram amostrados 411 indivíduos, 44 espécies e 21 famílias botânicas. As famílias Fabaceae e Bignoniaceae apresentaram as maiores riquezas. Os valores dos índices de diversidade de Shannon-Weaver e de equabilidade de Pielou foram considerados elevados (3,18 e 0,84, respectivamente). A similaridade florística entre os conglomerados foi alta (índice de Sørensen = 74,63%), indicando homogeneidade no fragmento. A distribuição diamétrica apresentou o padrão J-invertido. A comunidade apresentou tendência ao agregamento, com índice de agregação de Payandeh médio (1,40). A riqueza e estrutura da vegetação indicaram bom estado de conservação do estrato arbóreo-arbustivo, pois não foram observadas alterações florístico-estruturais no fragmento oriundas das pressões antrópicas do entorno da área.Embrapa Florestas2020-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/174210.4336/2020.pfb.40e201801742Pesquisa Florestal Brasileira; v. 40 (2020)Pesquisa Florestal Brasileira; Vol. 40 (2020)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/1742/1619Copyright (c) 2020 Otávio Miranda Verly, Iuri Maicon Moreira de Oliveira, Cristman Taísse Félix dos Santos, Leonardo Leite Fialho Junior, Poliane Rodrigues Rosa, Arthur Guilherme Schirmbeck Chaves, Fernanda Miguel Francohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessVerly, Otávio MirandaOliveira, Iuri Maicon Moreira deSantos, Cristman Taísse Félix dosFialho Junior, Leonardo LeiteRosa, Poliane RodriguesChaves, Arthur Guilherme SchirmbeckFranco, Fernanda Miguel2020-09-28T20:35:31Zoai:pfb.cnpf.embrapa.br/pfb:article/1742Revistahttps://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:2020-09-28T20:35:31Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
