- POPULATION STRUCTURE AND SPATIAL DISTRIBUTION OF Bauhinia cheilantha (Bong.) Steud. IN TWO FRAGMENTS AT DIFFERENT REGENERATION STAGES IN THE CAATINGA, IN SERGIPE, BRAZIL Ana Cecília da Cruz Silva Diogo Gallo de Oliveira Agrociencias Mororó Aggregation Population density ABSTRACT – This study aimed to analyze the vertical and diameter structure and the spatial distributionpattern of Bauhinia cheilantha in two Caatinga fragments in Sergipe, Brazil, at different regeneration stages.Thirty plots were demarcated in area I (Canindé de São Francisco and Poço Redondo), which has vegetationregeneration, and 25 plots in area II (Porto da Folha) with preserved vegetation, both having 400 m2. AllB. cheilantha individuals had their height and circumference (circumference at breast height > 6 cm) measured.Possible differences in height and diameter at breast height were tested in the two populations by using Student’sT-test. The distribution pattern of species was calculated through Payandeh’s index. We sampled 154 B. cheilanthaindividuals, equivalent to 33.3% of the plots in area I and in 1,027 individuals in area II, totaling 100% frequency.Height and the diameter of the two populations were statistically different, where AI achieved all values lowerthan AII. The spatial distribution pattern of B. cheilantha found in both areas was aggregate, with valuesof 11.85 and 9.00, respectively. Thus, it became clear that the population in AII is at a more advanced successionalstatus than AI, due to its longer conservation time. 2015 artículo científico 0100-6762 https://www.redalyc.org/articulo.oa?id=48842213003 en http://www.redalyc.org/revista.oa?id=488 Revista Árvore application/pdf Universidade Federal de Viçosa Revista Árvore (Brasil) Num.3 Vol.39
