Efeito do uso e cobertura da terra na dinâmica do carbono e nitrogênio em turfeiras na várzea do rio Paraíba do Sul
As turfeiras armazenam grande quantidade de carbono (C) e têm atuado como sumidouros de CO2 atmosférico, mas também podem se comportar como importantes fontes de Gases de Efeito Estufa (GEE) para a atmosfera (CO2, CH4 e N2O) quando submetidas a drenagem e mudança no seu uso alterando a cobertura...

Compound drought–heat extremes in the Pantanal region during 2019–21: causes and environmental impacts
The Pantanal region in South America is one of the worlds largest wetlands. Since 2019, the Pantanal has suffered a prolonged drought that has spelled disaster for the region, and subsequent fires have engulfed hundreds of thousands of hectares, and this situation has worsened in 2021. The lack of r...

Validation of the Brazilian Global Atmospheric Model with the inclusion of aerosols.
The Suns radiation is the primary energy source for chemical, biological, and physical processes that happen in the climate system. Thus, the earth-atmosphere radiative balance system is one of the main aspects of climate change. Natural fluctuations in incident solar radiation caused by the sunspot...

Characteristics of lightning-caused wildfires in central Brazil in relation to cloud-ground and dry lightning
Lightning ignition is the major cause of natural wildfires in several regions worldwide. Determining if wildfires in remote uncontrolled areas result from natural lightning as opposed to anthropic action is a relevant and yet-unsolved challenge for large regions of the planet, with scientific and ma...

Evaluating the performance of radiometers for solar overirradiance events.
This paper describes a methodology used to evaluate pyranometers and reference cell performance in relation to solar overirradiance (OIR) events. By definition, these events are characterized when global horizontal irradiance (GHI) exceeds the extraterrestrial horizontal irradiance (ETH) due to clou...

Brazilian biomes distribution: past and future
The Last Glacial Maximum (LGM, 26.519 ka) was marked by atmospheric cooling, in contrast to the current warming climate, which will probably continue in the coming decades, according to climate models projections. The LGM to pre-industrial transition provides an opportunity to test the vegetation re...

Climate change could reduce and spatially reconfigure cocoa cultivation in the Brazilian Amazon by 2050.
Cocoa is a plant with origins in northwestern South America with high relevance in the global economy. Evidence indicates that cocoa is sensitive to a dry climate, under which crop production is reduced. Projections for future climate change scenarios suggest a warmer and drier climate in the Amazon...

Multitemporal spatial analysis of land use and land cover changes in the lower Jaguaribe Hydrographic sub-basin, Ceará, Northeast Brazil.
Aquaculture is currently one of the fastest growing food production systems globally, and shrimp is considered one of the most highly valued products. Our study area is the lower Jaguaribe River sub-basin (LJRSB), located in the northeastern part of Ceará in Brazil. The aquaculture activity in this...

Low- or high-white light irradiance induces similar conidial stress tolerance in Metarhizium robertsii.
White light during mycelial growth influences high conidial stress tolerance of the insect-pathogenic fungus Metarhizium robertsii, but little is known if low- or high-white light irradiances induce different stress tolerances. The fungus was grown either in the dark using two culture media: on mini...
