In each of 25 20 × 20 m plots, where the adult component and environmental variables have previously been evaluated, subplots of different sizes varying according to plants' height were then allocated as follows: Class 1 - plants with a height varying from 0.15 cm up to 1 m, being evaluated within 5 m2; Class 2 - plants with a height varying from 1 up to 3 m, being evaluated within 10 m2; Class 3 - plants with a height greater than 3 m and DBH smaller than 5 cm, being evaluated within 20 m2. Data have been analyzed with regard to the determination of diversity (Shannon index), evenness (Pielou), Natural Regeneration Index (NRI), similarity with the adult component (Jaccard and Bray-Curtis), floristic-structural organization (Nonmetric Multidimensional Scaling - NMDS) and their relation to environmental variables. A total of 518 individuals distributed in 28 species were sampled. The low values of Shannon index (2.51 nat/ind) and evenness (0.75) suggest low diversity and elevated ecological dominance. The highest NRI has been found in the species Symphyopappus itatiayensis (Hieron.) R.M.King & H.Rob (19.36%). The similarity with the adult component were of 0.45 (Jaccard) and 0.24 (Bray- Curtis), demonstrating a low overall similarity (<0.50). The soil compaction was the only variable that has shown a relation with regeneration, which can be related to cattle's presence in the fragment. 2016 artículo científico 0100-6762 https://www.redalyc.org/articulo.oa?id=48849820013 en http://www.redalyc.org/revista.oa?id=488 Revista Árvore application/pdf Universidade Federal de Viçosa Revista Árvore (Brasil) Num.6 Vol.40 |
