In 2016, the dominant greenhouse gases released into Earth's atmosphere-carbon dioxide, methane, and nitrous oxide-continued to increase and reach new record highs. The 3.5 ± 0.1 ppm rise in global annual mean carbon dioxide from 2015 to 2016 was the largest annual increase observed in the 58-year ...

Simulation of surface fluxes in two distinct environments along a topographic gradient in a Central Amazonian Forest using the Integrated LAND surface model.
The Integrated Land Surface model (INLAND) land surface model, in offline mode, was 25 adjusted and forced with prescribed climate to represent two contrasting environments along a 26 topographic gradient in a central Amazon Terra Firme forest, which is distinguished by well- 27 drained, flat platea...

Deep soil water dynamics in an undisturbed primary forest incentral Amazonia: differences between normal years and the2005 drought.
Understanding how Amazonian rainforests deal with extended droughts is critical in the face of changing climate. This research analyze the physical properties and the soil water dynamics of a deep soil profile in an area of primary forest in central Amazonia to elucidate these processes under drough...

Model uncertainties do not affect observed patterns of species richness in the Amazon.
Background Climate change is arguably a major threat to biodiversity conservation and there are several methods to assess its impacts on species potential distribution. Yet the extent to which different approaches on species distribution modeling affect species richness patterns at biogeographical s...

Scenarios of vegetable demand vs. production in Brazil: the links between nutritional security and small farming.
Dietary guidelines urge Brazilians to increase their consumption of raw vegetables. Yet key issues must be tackled by the government and civil society, not only to foster consumers' appetite for healthier food, but more importantly to diminish the gaps between local demand and production, determined...

Fuel for cyclones: the water vapor budget of a hurricane as dependent on its movement.
Despite the dangers associated with tropical cyclones and their rainfall, the origin of the moisture in these storms, which include destructive hurricanes and typhoons, remains surprisingly uncertain. Existing studies have focused on the region 40400 km from a cyclone's center. It is known that the ...

Niche conservatism and the invasive potential of the wild boar.
Niche conservatism, i.e. the retention of a species' fundamental niche through evolutionary time, is cornerstone for biological invasion assessments. The fact that species tend to maintain their original climate niche allows predictive maps of invasion risk to anticipate potential invadable areas. U...

Climate trends on the extreme winds in Brazil.
The main source of electricity in Brazil is from hydro, which has about 65.2% share of the country's electric energy matrix. However, over the last decade the wind energy increased from 19 MW to 2.2 GW. Since wind is an intermittent energy source, heavily determined by the weather and climatic condi...

Drought in Northeast Brazil: past, present, and future.
This study provides an overview of the drought situation in Northeast Brazil for the past, present, and future. Droughts affect more people than any other natural hazard owing to their large scale and long-lasting nature. They are recurrent in the region and while some measures have been taken by th...
