13. Height-diameter relationships of tropical Atlantic moist forest trees in southeastern Brazil
Site-specific height-diameter models may be used to improve biomass estimates for forest inventories where only diameter at breast height (DBH) measurements are available. In this study, we fit height-diameter models for vegetation types of a tropical Atlantic forest using field measurements of height across plots along an altitudinal gradient. To fit height

16. Understory structure in riparian fragments of atlantic rainforest in the extreme north of Pernambuco, Brazil / Estrutura do sub-bosque em fragmentos ripÃrios na floresta atlÃntica do extremo norte, Pernambuco, Brasil
Deleterious changes in fragments of forest communities have been often associated to biotic and abiotic changes related to area and edge effects. The understory is an important component of forest communities and exhibits a clear response to the process of fragmentation, due to its susceptibility to such effects. In the Northern section of the Atlantic Fores

17. Monitoring fruit flies (Diptera, Tephritidae) in five municipalities of the state of Goiás Brazil / Monitoramento de moscas-das-frutas (Diptera, Tephritidae) em cinco municípios no estado de Goiás
Fruit flies (Diptera, Tephritidae) are important insect pests in world fruit orchards; responsible for significant yield losses, and an obstacle to the fruit market due to quarantine restrictions imposed by importing countries. The knowledge of their population dynamics in a specific region is an important factor in insect pest management programs. Fruit fli

18. Análise de métodos de realce espectral e temporal aplicados à discriminação de classes de uso e cobertura da terra em áreas de Cerrado / Analysis methods of spectral and temporal enhancement applied to class discrimination use and land cover in areas Closed
O bioma Cerrado tem destaque nacional e internacional em virtude de sua dimensão, cerca de 205 milhões de hectares do território, além de se destacar como uma das áreas de importância global para a biodiversidade. Com 9,2% de sua área assegurada na forma de parque ou reserva ecológica, estudos do mapeamento da cobertura vegetal apontam um cenário de

19. Caracterización y monitoreo de paisaje semiárida en la Región del Maule mediante datos satelitales
The objective of this research is to apply the Radiometric Rotation Controlled by No-change Axis (RCNA) technique on Landsat TM images, 2004 and 2008, covering the coastal dry land of the Region of Maule, Chile, in order to obtain the spatial distribution of changes and degradation in the forest landscape. The RCNA procedure allows the use of images without

20. Soil properties for different uses in irrigated perimeter of Sertão in Pernambuco State. / Atributos do solo em função dos diferentes usos em perímetro irrigado do Sertão de Pernambuco
The semiarid Northeast Brazil, represented by the Caatinga biome is characterized as an environment of low water availability and shallow soils, which require regional scientific community, further studies directed at understanding and managing these resources, for their preservation in a sustainable way. Thus, this study aims to evaluate the chemical, physi

21. Desenvolvimento de uma metodologia para a estimativa de biomassa e de carbono em sistemas agroflorestais por meio de imagens orbitais / Development of a methodology to the estimation of biomass and of carbon in agroforestry systems for middle of orbits
Remarks indicate that naturals systems of the Earth are being affected for transformation about the ability of diverse region. Within the causes these changes, detach the emission of CO2 (Carbon Dioxide) way alteration in land use and land cover. The Amazonian region, in function of the occupation trajectory has received attention of the scientific community

23. 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,

24. Uso do solo na Bacia Hidrográfica do rio Camboriú (SC) e sua influência sobre a qualidade da água
The watershed of the Camboriú River is located in the cities of Camboriú and Balneário Camboriú. With a length of around 40 kilometers, it drains an area of 200 km2. This paper aims to characterize the Camboriú River watershed by determining space-time variations of physical, chemical and biological parameters of superficial water, as well as the soil o
