RESUMO:

The Caatinga Biome is spread over 826,411 km2 of the Brazilian Northeast and, between the bioclimatically similar regions, is the most diverse. Although significant advances have occurred in recent years, the Caatinga remains the least known Brazilian biome in terms of its biodiversity and the conservation status of its remnants. The filling of this gap is urgent, since the Biome already has approximately 50% of deforested areas and the rest is under strong pressure by firewood extraction, livestock, hunting, mining, among others. These facts, coupled with the low representativeness of the Caatinga in Conservation Units, threaten the biological patrimony of the Biome, making urgente studies that guide conservation strategies. The adoption of conservation strategies based on the structural characteristics of the landscape has generated relevant results, guinding efficiently and quickly field surveys and public environmental policies. This thesis is organized in four independent chapters that aim to expand, mainly based on analysis of the landscape structure, knowledge about the state of conservation and fragmentation of the Biome, allowing the identification of strategies and areas more relevant to the maintenance and recovery Of the biota. The first chapter, titled "Characterization of the Caatinga Biome Fragmentation", brings an analysis of the size, functional and structural connectivity and edge effect of all Caatinga remnants, allowing identification of patterns of fragmentation and opportunities for conservation. In the second chapter, entitled "Priority Areas for the Restoration of the Caatinga", we identified, based on the connectivity of the landscape and the existence of endangered species, which river basins should be primarily targets for restoration actions. The third chapter, "Chronic Potential Disruption of Caatinga Remnants", aims to bring to light information about the potential conservation status of Caatinga remnants, taking into account the intensity and spatial distribution of vectors of anthropogenic disturbance throughout The Biome. In the fourth chapter, "Conservation Planning and Actions in a Megadiverse Country", we compare the habitat loss inside the conservation priority areas in Brazilian biomes, identifying the policies constraints and suggesting a mechanism that will allow the expansion of the protected areas system in the Caatinga.
