Por exemplo, Condit et al. Estudo da cobertura vegetal em ambientes da caatinga com diferentes formas de manejo no assentamento Moacir Lucena, Apodi – RN. In the phytosociological study, individuals comprising 48 species, 38 genera and 24 families were sampled. In Ecological diversity in theory and practice edited by J.
Phytosociology of a dense ombrophilous forest in the northern Amazon, Roraima, Brazil
In the CCA, the environmental variables that have the best correlations between the plots and species were mean temperature, mean of the minimum temperature, mean annual precipitation, solar radiation and number of dry months. At PNSC, some of the soils sampled in the plots have a solodic characteristic, because of the high amounts of sodium, related to areas with higher altitudes.
In each area, we sampled ten plots with 20 m x 50 m, distributed in patches of cerrado on Entisols. At Chapada Grande Meridional 48 species two subspecies and 26 botanic families were encountered, with a stem density of indiv.
