Plots were systematically established at six distances (0, 40, 80, 160, 280 and 400 m) from the edge, over 10 orthogonal transects on the forest-pasture edge. It was sampled 602 adult individuals/ha, 8,927 saplings/ha and 54,167 seedlings/ha distributed in 58 species. Although the composition of seedlings and adult individuals varied significantly over the forest-pasture gradient, the variation explained by edge distance was below 4%. Among parameters of community structure and tested diversity indexes, there was significant variation only for diversity of seedlings and height of adult trees among forest-pasture edge distances. The dry forest fragment showed only a slight edge effect on the evaluated tree community parameters. This conclusion contrasts with findings from studies on tropical rain forests which indicate sharp differences between edge and interior tree communities in forest fragments. 2011 artículo científico 0100-6762 https://www.redalyc.org/articulo.oa?id=48819945018 en http://www.redalyc.org/revista.oa?id=488 Revista Árvore application/pdf Universidade Federal de Viçosa Revista Árvore (Brasil) Num.5 Vol.35 |
