13. Relações solo-vegetação no Parque Nacional da Serra do Cipó, Espinhaço Meridional, Minas Gerais / Soil vegetation relationships in the National Park Serra do Cipó, in Espinhaço Meridional, Minas Gerais
The region of Serra do Rio Cipó, in the southern part of the Serra do Espinhaço, comprises large areas of Cerrado, Atlantic forest, forest islands and one of the richest high-altitude rocky vegetation in Brazil. The ecotonal character between the Cerrado and Atlantic Forest biomes, described in many studies of regional flora and fauna, is one of the factor

14. Vegetação dunar: caracterização estrutural de dunas do município de Natal-RN como subsídio para implantação de técnicas de reflorestamernto, recuperação e conservação do ecossistema
The Brazilian coast has a wide variety of complex environments and ecosystems along the coast, about 80% are represented by sandbanks and dunes. The coastal ecosystems were the first to suffer the impacts man and places, as the very fragile ecosystems, are somehow altered. Are few areas of restinga well as natural features, very few protected in conservation

15. 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

16. Vegetation and soil gradient in the restinga forest in Espirito Santo, Brazil / Gradiente vegetacional e pedológico em floresta de restinga no Espírito Santo, Brasil
The Restingas are ecosystems that occur in sandy soils deposited during the Quaternary. These are known to have a high diversity of vegetation, but few studies provide information on abiotic factors determining this diversity. This study aimed to: (i) assess the influence of the chemical aspects, physical soil and flooding in phytophysionomic determination,

17. Niche characterization of Sporophila spp. (Aves: Emberizidae) and its relation to microhabitat in palm swamp areas near Uberlândia, MG / Caracterização de nicho de Sporophila spp. (aves: Emberizidae) e sua relação com a estrutura de microhabitat em áreas de vereda de Uberlândia, MG
The relative importance of each environmental factor in structuring birds community seems to be variable, and each species exhibits a distinct and specific response to environmental characteristics and their changes. Some granivorous birds can perform seasonal migrations in search of good seeds. They often include the brazilian cerrado, both for breeding and

18. Characterization of the shrub and tree vegetation from Montane Ombrophilous Dense Forest fragments / Caracterização da vegetação arbustivo-arborea de fragmentos de Floresta Ombrofila Densa Montana
The Atlantic Forest possesses enormous biodiversity and is highlighted by the high floristic diversity and endemism in some plant groups. The Atlantic Forest is among the most endangered tropical forests in the world and most of its remnants are small and altered fragments, or larger areas in mountains, with pronounced slope. Knowledge of the forest remnants

20. Aspectos da dinamica de clareira em uma floresta estacional semidecidual no municipio de Campinas, SP
The present paper was developed in ten natural gaps of Santa Genebra Municipal Reservation (22°49 45"S and 47°06 33"W) in Campinas, SP. For the characterization of the gaps the canopy area and opening were determined using hemispherical photographs. The shrub and tree individuais with height ? 0,50 m were sampled in the total area and in the gaps as well a

21. Organização e estrutura das comunidades vegetais de cerrado em um gradiente topografico no Brasil central
Several lines of evidence suggest that the variation in Cerrado physiognomy is determined and maintained by fire. The objective of this study was to determine and describe pattems indicating that after 19 yr of fire protection, the Cerrado vegetation developed to a high density and cover mature vegetation. The hypothesis of this study was that protected Cerr
