Resumo: | Fragmentation is a consequence of anthropic actions that cause changes in land use and cover. Owing to the conversion of forest areas into agricultural use areas, riparian vegetation becomes susceptible to the effects of fragmentation. This generates changes that affect the structure and composition of vegetation in the forest remnants. Therefore, this study aimed to analyze the structure and floristic composition of riparian vegetation with 30 m in a fragmented matrix. Accordingly, adult vegetation (DBH ≥ 5 cm) and regeneration (height ≥ 10 cm, diameter <5 cm) in 10 x 30 m plots were sampled in three stretches of riparian vegetation, two stretches in a pasture matrix and one stretch in matrix with native vegetation. Compared to the area with matrix of native vegetation, the vegetation of riparian areas immersed in pasture matrix showed a floristic composition dissimilarity and some structural similarity. In the regeneration, a high abundance of the species Olyra cf. ecaudata Döll (Poaceae) and Asplenium cf. inaequilaterale Willd. (Aspleniaceae) was observed. Our results provide evidence that the structure of riparian areas with 30 m in the pasture matrix was preserved. However, the performance of the ecological functions of riparian vegetation could be affected over time due to the effects of fragmentation that are influencing the diversity of these areas. |

Com a conversão de áreas florestais em áreas de uso agrícola, a mata ciliar torna-se suscetível aos efeitos da fragmentação. Isso gera mudanças que afetam a estrutura e composição da vegetação dos remanescentes florestais. Portanto, este estudo teve como objetivo analisar a estrutura e composição florística de mata ciliar com 30 m em uma matriz fragmentada. Assim, a vegetação adulta (DAP ≥ 5 cm) e regeneração (altura ≥ 10 cm, diâmetro <5 cm) em parcelas de 10 x 30 m foram amostradas em três trechos de mata ciliar, sendo dois trechos em uma matriz de pastagem e um trecho em matriz com vegetação nativa. Comparada à área com matriz de vegetação nativa, a vegetação de matas ciliares imersa em matriz de pastagem apresentou dissimilaridade de composição florística e alguma similaridade estrutural. Na regeneração, uma grande abundância das espécies Olyra cf. ecaudata Döll (Poaceae) e Asplenium cf. inaequilaterale Willd. (Aspleniaceae) foi observada. Nossos resultados fornecem evidências de que a estrutura das matas ciliares de 30 m na matriz de pastagem estava preservada. Porém, o desempenho das funções ecológicas da mata ciliar também pode ser alterado ao longo do tempo devido aos efeitos da fragmentação que estão influenciando a diversidade dessas áreas.Universidade Federal Rural da Amazônia/UFRA2021-11-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/3477Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 64 (2021): RCA AJAESRevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 64 (2021): RCA AJAES2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
