Resumo: This study aimed to characterize the dynamics, structural changes and floristics of a Northern Minas Gerais Seasonally Deciduous Forest tree community, in a 5 year interval. In 2005, 10 (20 x 20m) plots were allocated. All trees (CBH > 10 cm) were tagged and measured. A second census was carried out in 2010 in order to measure surviving, new recruits and dead trees. In 2005, 46 species were recorded, moving to 45 in 2010. No significant differences were found for Shannon – diversity (H’ = 2.62 nats ind-1 in 2005; H’ = 2.60 nats ind-1 in 2010) and Pielou eveness (J = 0.683 in 2005; J = 0.682 in 2010) in the interval. A total of 57 dead records (rate of 1.64% year-1) were found whereas 18 trees were recruited (rate of 0.53% year-1). Despite the higher mortality as compared to recruitment, the results suggest that the community remained stable in both structural and diversity terms in the interval considered.

Em 2005, foram alocadas 10 parcelas de 20x20m. Os indivíduos com CAP > 10 cm foram marcados com etiquetas numeradas e mensurados. Em 2010, no segundo inventário, foram incorporados os recrutas, registrados os mortos e remedidos os sobreviventes. Em 2005 foram registradas 46 espécies, e em 2010 foram 45 espécies. O índice de Shannon-Wienner (H’ = 2,62 nats ind-1 em 2005; H’ = 2,60 nats ind-1 em 2010) e a equabilidade de Pielou (J = 0,683 em 2005; J = 0,682 em 2010) não apresentaram diferenças significativas. Foram registrados ao todo 57 indivíduos mortos, com taxa de mortalidade média de 1,64% ano-1. Enquanto ocorreram 18 recrutas, apresentando taxa de recrutamento médio de 0,53% ano-1 . Apesar da maior mortalidade, em comparação com o recrutamento, os resultados sugerem que a comunidade se manteve estável tanto em termos estruturais e de diversidade no intervalo considerado.Universidade Federal de Viçosa2019-06-19T16:40:24Z2019-06-19T16:40:24Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfREIS, G.
