Canopy-scale biophysical controls of transpiration and evaporation in the Amazon Basin
Canopy and aerodynamic conductances (gC and gA) are two of the key land surface biophysical variables that control the land surface response of land surface schemes in climate models. Their representation is crucial for predicting transpiration (λET) and evaporation (λEE) flux components of the te...

Development and evaluation of species distribution models for five endangered elasmobranchs in southwestern Atlantic
Species distribution models (SDMs) are tools to obtain habitat suitability maps based on historical species occurrences and environmental variables. Those maps can be used to restrict fishing grounds or to assist in planning and reserve selection. This is especially important for species at risk of ...

Effects of particulate matter and its chemical constituents on elderly hospital admissions due to circulatory and respiratory diseases.
Various fractions of particulate matter have been associated with increased mortality and morbidity. The purpose of our study is to analyze the associations between concentrations of PM2.5, PM2.5-10, PM10 and their chemical constituents (soluble ions) with hospital admissions due to circulatory and ...

Bright spots: seeds of a good Anthropocene
The scale, rate, and intensity of humans environmental impact has engendered broad discussion about how to find plausible pathways of development that hold the most promise for fostering a better future in the Anthropocene. However, the dominance of dystopian visions of irreversible environmental de...

CH4 concentrations over the Amazon from GOSAT consistent with in situ vertical profile data
The Amazon Basin contains large wetland ecosystems which are important sources of methane (CH4). Spaceborne observations of atmospheric CH4 can provide constraints on emissions from these remote ecosystems, but lack of validation precludes robust estimates. We present the first validation of CH4 col...

Land-use and climate change risks in the Amazon and the need of a novel sustainable development paradigm
For half a century, the process of economic integration of the Amazon has been based on intensive use of renewable and nonrenewable natural resources, which has brought significant basin-wide environmental alterations. The rural development in the Amazonia pushed the agricultural frontier swiftly, r...

The socioecological implications of land use and landscape change in the brazilian Amazon
The search for a sustainable model of development for the Brazilian Amazon has underpinned an increasing number of public policy decisions and new legislation governing how land is managed in order to conserve and maintain ecosystem functions and services. Socio-environmentalism constitutes a relati...

Land use, land cover and land use change in the Amazon (1960-2010)
Tropical forests play a critical role in the global carbon budget, and the Amazon region in South America has particular importance since it represents half the worlds rainforest area and is home to one-third of Earths species. In the recent past, parts of Brazilian Amazon faced high rates of defore...
