Complex socio-ecological dynamics driven by extreme events in the Amazon.
Several years with extreme floods or droughts in the past decade have caused human suffering in remote communities of the Brazilian Amazon. Despite documented local knowledge and practices for coping with the high seasonal variability characteristic of the regions hydrology (e.g., 10 m change in riv...

Hand terrain descriptor for mapping regional scale eco-hydrological units of amazon terra firme.
The HAND (Height Above the Nearest Drainage), a quantitative topographic descriptor, is used to classify terrain in a manner that is related to local soil water conditions, providing hydrological meaning to the SRTM DEM. In this paper, we compare performance of using the HAND grid instead of the SRT...

The effects of river inflow and retention time on the spatial heterogeneity of chlorophyll and water–air CO2 fluxes in a tropical hydropower reservoir.
Abundant research has been devoted to understanding the complexity of the biogeochemical and physical processes that are responsible for greenhouse gas (GHG) emissions from hydropower reservoirs. These systems may have spatially complex and heterogeneous GHG emissions due to flooded biomass, river i...

Extreme flood events in the Bolivian Amazon Wetlands.
Study region: The Amazonian wetlands of Bolivia, known as the Llanos de Moxos, are believed to play a crucial role in regulating the upper Madeira hydrological cycle, the most important southern tributary of the Amazon River. Because the area is vast and sparsely populated, the hydrological function...

. 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...

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:...

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...

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...

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...
