The results pointed out that the desertification triggered pervasive changes on the floristic composition of the Caatinga biome, indicating also that the human-induced disturbances were determinants to the establishment of the different environments.

Resumen
The desertification is recognized as a major threat to the dry climate zones around the world. In Brazil, it has reached mainly the Caatinga biome for which still there is little information regarding its outcomes on the floristic composition. Herein, the aim was assessing this effect in sites within three municipalities of Paraiba State (Northeast Brazil). Sampling sites were previously selected by satellite images using NDVI technique, followed of a vegetation survey in locu (transect method) encompassing non-desertified and desertified environments. Univariate (U test) and multivariate (nMDS) analysis were used to verify differences in the vegetational variables and to demonstrate dissimilarities patterns between the contrasting environments, respectively. Richness and diversity of plants differed significantly between environments. The nMDS identified three groups of plants: i) species associated to non-desertified areas (Anadenanthera columbrina, Bauhinia cheilantha and Tabebuia impetiginosa), ii) species related to desertified areas (Aspidosperma pyrifolium, Jatropha molissima, Mimosa tenuiflora and Pilosocereus gouneleii), and iii) species with high density in both environments (Croton sonderianus, Piptadenia stipulacea and Poincianella pyramidalis). The results pointed out that the desertification triggered pervasive changes on the floristic composition of the Caatinga biome, indicating also that the human-induced disturbances were determinants to the establishment of the different environments.
