13. Espécies invasoras em sítios de restauração florestal de floresta estacional
Exotic invasive species are the second greatest cause of biodiversity loss in the world. In forest restoration, these invaders can cause serious problems, like the suppression or exclusion of plants through competition and changes in the environment. Among these species, tropical invasive grasses are responsible for heavy costs and contribute to several setb

14. Panorama atual da produção de carvão vegetal no Brasil e no Cerrado.
ABSTRACT: The charcoal production from planted forests has been insufficient to take care of the demand and has implied in more pressure on the forest remainders, in special of the biome Cerrado. In 2005, the charcoal consumption in Brazil reached 38 million of MDC (Meter of Charcoal). The evolution of the charcoal consumption produced from native species pa

15. Estoque de carbono nos solos da bacia do Rio Araguari-MG: estimativas, modelagem e cenários
The soils can act as a source or carbon sink to the atmosphere, depending on the climate conditions and, especially, the type of use and management adopted. Taking into consideration the stock/sequestration carbon potential, admittedly, attributed to several land uses, as in planted forests (Pinus and Eucaliptus), and no-till areas, as well as the efficiency

16. Equações de biomassa e estoques de carbono de seis espécies em plantios mistos no noroeste do Mato Grosso
During this time of discussion about global warming and climate change, environmental restoration projects thought as a CO2 sink in its plant biomass are essential in the fighting the increasing concentration of global warming greenhouse gases. One very eficient method to sequester atmosphere carbon is through reforestation and quantifying the resulting stan

17. Sucessão secundária em áreas de Mata Atlântica de Pernambuco : mudanças florísticas e estruturais
Secondary forests have been considered as priority areas for conservation in tropical regions due to their possible role as buffer zones. They serve as habitats for plants and animals coming from destroyed mature forests and as corridors between forest fragments. They also have the capacity to accumulate biomass and nutrients at high rates, to maintain bioge

18. Biomassa e energia
Biomass was the dominating source of energy for human activities until the middle 19th century, when coal, oil, gas and other energy sources became increasingly important but it still represents ca. 10% of the worldwide energy supply. The major part of biomass for energy is still "traditional biomass" used as wood and coal extracted from native forests and t

19. Análise de imagens do satélite ALOS PALSAR (Banda L, modo polarimétrico) para discriminação de coberturas de terras no Distrito Federal
Land cover maps are important source of data for environmental monitoring, biodiversity conservation, social, economic and environmental zonning, and local and global climatic changes, among other activities. In the Federal District of Brazil (FD), land cover mappings have been obtained from optical images. However, radar data are valuable alternative for th

20. Avaliação de dois trechos de uma Floresta Estacional Semidecidual restaurada por meio de plantio, com 18 e 20 anos, no Sudeste do Brasil / Evaluate of two patch of an Semideciduous Seasonal Forest restored through a plantation, with 18 and 20 years, in Southeastern of Brazil
Restoration actions in degraded areas have been widely used, as much for legal requirements as for initiatives of groups worried about the ambient quality, in this way not having an standardizing of this actions. Appearing the necessity to evaluate if the employed methodologies are reaching its objective and providing a self-sustentation of the formed forest

21. Volumetria, calorimetria e fixação de carbono em florestas plantadas com espécies exóticas e nativas usadas como fonte energética no Polo Gesseiro do Araripe PE. / Volumetry, calorimetry and carbon fixation in forests planted with exotic and native species used as energy source in the Gypsum Pole of Araripe -PE.
In the industrial and commercial sectors of the Araripe Region in Pernambuco, the use of fire wood is mainly directed to the processes of calcination and production of gypsum in different technologies. Thus, this study aimed to find alternatives to supply the demand of firewood in the Gypsun Pole of Araripe in Pernambuco through the implementation of the for

22. Avaliações energéticas de espécies florestais nativas plantadas na região do Médio Paranapanema, SP / Energy assessments of Brazilian species planted in the region of the Middle Paranapanema, SP
The use of renewable sources of energy is a worldwide trend and is being increasingly widespread, mainly for environmental and economic reasons. Biomass has become one of the most commonly used renewable sources of energy in the last years. Many of the biomass fuels used today comes in the form of wood products and others sources. In Brazil, woody biomass ha
