. On the ability of a global atmospheric inversion to constrain variations of CO2 fluxes over Amazonia.
The exchanges of carbon, water and energy between the atmosphere and the Amazon basin have global implications for the current and future climate. Here, the global atmospheric inversion system of the Monitoring of Atmospheric Composition and Climate (MACC) service is used to study the seasonal and i...- por Portal Padrão

Exploratory analyses for the assessment of climate change impacts on the energy production in an Amazon run-of-river hydropower plant.
Study region: The Tapajós Basin is an important Amazon tributary affected byhuman activities with great potential for water conflicts. The basin, as otherswithin the Amazon region, is receiving a number of hydropower plants, amongthem the Teles Pires plant, projected to operate in 2015.Study focus:...- por Portal Padrão

Soil texture and chemical characteristics along an elevation range in the coastal Atlantic Forest of Southeast Brazil.
We analyzed soils under forest across an elevation range (100 m, Lowland Forest, 400 m, Submontane Forest, and 1000 m, Montane Forest) in the Atlantic Rainforest of São Paulo State, Brazil. We hypothesized that soil nutrient content would increase with elevation in the surface mineral soil as a res...- por Portal Padrão

Precipitation in the Amazon and its relationship with moisture transport and tropical Pacific and Atlantic SST from the CMIP5 simulation.
Studies on numerical modeling in Amazonia show that the models fail to capture important aspects of climate variability in this region and it is important to understand the reasons that cause this drawback. Here, we study how the general circulation 5 models of the Coupled Model Intercomparison Proj...- por Portal Padrão

Potential land availability for agricultural expansion in the Brazilian Amazon.
The Amazon hosts one of the largest stocks of arable land in the world. However, little is known about the available extent of agricultural land in conformity with legal, agronomical and environmental requirements. This study aims to identify and quantify potentially available areas for agricultural...- por Portal Padrão

Comments on “the tropospheric land-sea warming contrast as the driver of tropical sea level pressure changes”.
In their paper "The tropospheric land-sea warming contrast as the driver of tropical sea level pressure changes,'' Bayr and Dommenget proposed a simple model of temperature-driven air redistribution to quantify the ratio between changes of sea level pressure p(s) and mean tropospheric temperature T-...- por Portal Padrão

Panorama da sustentabilidade na fronteira agrícola de bioenergia na Amazônia.
Esta pesquisa apresenta um panorama da sustentabilidade em sete municípios paraenses, que fazem parte do polo de produção do dendê (Elaeis guineensis Jacq.) na Amazônia oriental. Trata-se de uma área com aproximadamente 46.000 km² que apresenta diferentes padrões de usos da terra, considerad...- por Portal Padrão

Hybrid color segmentation method using a customized nonlinear similarity function.
Image segmentation is a fundamental step in several image processing tasks. It is a process where an image is divided into its constituent regions guided by a similarity criterion. One very interesting image segmentation method is the color structure code (CSC), which combines simultaneously split-a...- por Portal Padrão

Integrating forest cover change with census data: drivers and contexts from Bolivia and the lao PDR.
The aim of this paper is to explore possible links between forest cover change and characteristics of social-ecological systems at sub-national scale based mainly on census data. We assessed relationships between population density, poverty, ethnicity, accessibility and forest cover change during th...- por Portal Padrão
