Diversity of α and β in Two Fragments of Seasonal Deciduous Forest
Publicação on-line; 46 ref.; 1 table; 3 illus.; Summary (En)
Abstract
The aim of this study was to evaluate the floristic and structural differences between two fragments of Seasonal
Deciduous Forest in the São Francisco river, Minas Gerais. A total of 25 plots of 20×20 m in each fragment were
allocated and all living individuals with Circumference at Breast Height (CAP) ≥ 15.7 cm were considered. The
Shannon-Wienner indices and the Pielou equitability were equal among sampled areas. The Jaccard and Bray-Curtis
similarities were 20.7% and 41%, respectively, indicating a high β diversity. Non-metric Multidimensional Scaling
(NMDS) resulted in two floristic groups, distinguishing the flora of Presidente Juscelino and Paracatu. These results
showed that the areas are floristically different but resemble each other in terms of diversity and structure.
