Consequently, the distribution of the number of individuals has become more uniform, resulting in a greater diversity and taller individuals in the center.
Functional Ecology, London, v. The distance between the center and ecolobia edge of the islands ranged from 3 m to 6 m. The caatinga is characterized by having two well defined seasons: No trivia or quizzes yet. The mean richness of the center and the edge of the islands were similar table 2.
HardcoverSecond editionpages. The differences in average richness, densities, heights and diameters between the center, edge, and open space areas were checked by the Kruskal-Wallis variance test ZAR, Troy Mutton rated it liked it Aug 12, Want to Read saving….

Na rated it liked it Dec 22, Abundance of species of herbs found in the center and at the edge of the islands of woody vegetation and in open spaces in an area of caatinga embedded on a sedimentary basin in a semiarid region of the northeast region of Brazil.
