a tropical deciduous vegetation growing sparselyin the forests of northeastern Brazil. The constant arid conditions, interrupted by short rains, favor mainly the growth ofscrubs, medium-height trees, and shrubs. The caatinga is charac-terized by bottle trees, thorny trees, and leaf succulents (sunspurges and cacti) and cauline succulents.

No entanto, sabe-se que algumas especies exoticas possuem alto potencial de biomassa, mas nao se tem dados concretos sobre a sua producao nas condicoes do semiarido brasileiro, embora o genero Leucaena suporte condicoes de estresse hidrico como as que ocorrem no bioma Caatinga, alem de se apresentarem como forrageiras (OLIVEIRA et al.
Esse enclave de mata umida configura uma formacao de altitude que pelo grau de similaridade vegetacional e floristica, representa remanescentes da mata pluvial driatica (Mata Atlantica ou Floresta Serrano Oriental), validas como disjuncoes florestais em meio as caatingas circunjacentes.
Com base no exposto, o presente trabalho foi desenvolvido com o objetivo de prospectar especies da flora nativa do Bioma Caatinga ocorrentes no Vale do Submedio Sao Francisco que apresentem elementos esteticos apropriados para uso no paisagismo.
In this study we build on the recent acceleration in the development and publication of floristic and phytosociological studies for the Caatinga Domain to provide: 1) a brief overview of the main geographical and biological features of the Brazilian semiarid; 2) a metaanalysis of plant biogeography of Caatinga, exploring phytogeographical patterns based on the Caatinga database developed by Moro et al.
Our study focused on the floristic compositions of the herbaceous-subshrub and shrub-arboreal layers, life forms, rainfall, and soil properties in addressing the question of which factors are most important in defining the cerrado and caatinga vegetation along this transect.
For example, Lovette (2004b) finds a strongly supported relationship between Guyanan and Atlantic forest populations in the Phaeothlypis wood-warbler complex, while a similar study of the Synallaxis ruficapilla species group showed evidence for an affinity between Caatinga populations and those in the N Andean foothills (Batalha-Filho et al.
The Caatinga biome accounts for about 60% of the northeast Brazilian territory and extends to a small part of the northeastern Minas Gerais State (Sampaio et al.

El territorio de la Cuenca de Jacuipe, territorio rural y el alcance del bioma Caatinga, encajado en el nordeste semiarido, ubicado en Bahia, uno de los veintisiete estados brasilenos, expresa su forma de vivir y el uso de la tierra sobre la base de la agricultura familiar, su historia de ocupacion y uso de la tierra, marcada por la deforestacion y la fragmentacion de la vegetacion nativa vinculada a la ganaderia, la concentracion de la tierra y grandes propiedades y la manera de hacer politica con una base social organizada.
