Abstract: Given the enormity of the territory and the actual situation of the Brazilian macro biomes – Brazilian Amazonia, Brazilian Tropical Atlantic Forest, Cerrados of Central Brazil, Araucaria Plateau, and the Mixed Subtropical Grasslands of Brazil – and its numerous mini-biomes, transition areas and remnants of ecosystems, any attempt to change the Brazilian Forest Code has to be conducted by competent and…

natureza se encontra, algumas atitudes obtem exito e outras não. Palavras chaves: Impactos, Ecossistemas, Brasil Abstract The five Brazilian ecosystems are the Amazon, Cerrado, Atlantic Forest, Caatinga, Pantanal and Pampas. They are of great importance not only for Brazil but for the world, but the man did not care all of these biomes and caused various impacts on their means. Currently, the society tries to reverse the current state in which the nature is, some attitudes and some do…

release of these gases in the atmosphere. It also demonstrates how climate change may influence the current configuration of biomes and distribution of food, mainly influenced by the increase of temperature and frequency disturbances in the rains. Addressing how environmental impacts caused by the extensive agriculture and global warming undermine the preservation of the Amazon rainforest represents 12% of all the flora found in the world and is considered one of the most important…

with 82 to 48. The biomes most often studied were Atlantic (49%), Savannah (24%) and Amazon (15%). Considering the number of federal conservation units in the country, one realizes that they are still very poorly studied. It is necessary to devote special attention to marine and Pantanal biomes, due to low scientific production devoted to them, despite its importance and uniqueness. KEYWORDS: National System of Conservation Units, National Register of Conservation Units, biomes…

Paula Arruda Fernandes; Vera Lúcia Salazar Pessôa Abstract Cerrado is one of the most threatened biomes in Brazil. Many activities are impacting directly or indirectly affecting the biome, among them the mining and agriculture. This biome has not received the deserved attention for government authorities, and are often overlooked for various reasons, among them the great global importance of the Amazon. The Cerrado has been based on deforestation of vast areas, decreasing its area.…

environmental importance in reuse of these. Owing to the environment as a Caatinga biome underexplored and with a variety of oil plants, this project aims to produce biopolymers with the greatest application and profitability: the Polyhydroxyalkanoates (PHA). These are biosynthesis of carbohydrates produced by the plant Pinhão Manso oil (Jatropha curcas L) which is a native plant of the Brazilian caatinga and easily found in this biome, thus bringing the prospect of biotechnological…

through atmospheric teleconnections. However, forest-atmosphere interactions are complex, and small-scale, heterogeneous deforestation may produce mesoscale circulations that enhance clouds and precipitation. Flux tower measurements in the Brazilian Amazon confirm that forests have lower albedo compared with pasture, greater net radiation, and greater evapotranspiration, particularly during the dry season (11, 12), producing a shallow, cool, and moist boundary layer. Observations show…
