|metadata.revistascielo.dc.description:||This work aimed to verify the existence of variations in composition and distribution of tree species due to soil characteristics in a fragment of dystrophic savanna in Curvelo-MG. On description in the compartment of the phanerophytes of this plant community, were installed ten permanent plots with 1.000 m² (20 x 50 m) with fixed distances of 100 m between each plot. All alive individuals that had diameter at soil height (DSH - diameter to 0.3 m from ground level) > 5.0 cm were sampled. The Individuals with multiple boles were sampled when the value of square root of the sum-square of DSH had been greater than criterion of the inventory. Were collected Soil samples at two depths (0-20 e 20-40 cm) and was measured the distances of plots of a watercourse. To study the community were generated ordination diagrams of plots, species and environmental variables by means of a canonical correspondence analysis (CCA). The richness sampled was 92 species, 36 families and 74 genera, highlighting Erythroxylum, Byrsonima, Myrcia and Qualea. Jackknife estimators (first and second order) designed a wealth of 106.4 and 107.8 species. The species Magonia pubescens, Terminalia argentea, Annona crassiflora, Eugenia dysenterica e Xylopia aromatica were distribuited underneath the environmental gradient.|
