Looking to future perceptions about climate change in Brazil: what children’s teachers think, learn and teach about?
The social and human sciences have had a minor role in the studies of climate change. There remains a signifcant gap in our knowledge and understanding of the many facets of this theme. The educational sector has been neglected in the climate change scientifc debate, although it is acknowledged as a...

How to prioritize areas for new ant surveys? Integrating historical data on species occurrence records and habitat loss.
Habitat loss is a leading cause of extinctions, which may occur even before species are recorded or formally described. On the other hand, limitations in species distribution data and sampling biases can hamper inferences about patterns of species richness that form the basis of conservation strateg...

Determination of region of influence obtained by aircraft vertical profiles using the density of trajectories from the hysplit model
Aircraft atmospheric profiling is a valuable technique for determining greenhouse gas fluxes at regional scales (104106 km2 ). Here, we describe a new, simple method for estimating the surface influence of air samples that uses backward trajectories based on the Lagrangian model Hybrid Single-Partic...

CO(2) emissions from forest degradation in Brazilian Amazon.
Forest degradation is widespread around the world, due to multiple factors such as unsustainable logging, agriculture, invasive species, fire, fuelwood gathering, and livestock grazing. In the Brazilian Amazon forest degradation from August 2006 to July 2016 reached 1,1 869 800 ha. The processes of ...

Enhancement of Cloudless Skies Frequency over a Large Tropical Reservoir in Brazil.
Several studies show the effects of lake breezes on cloudiness over natural lakes and large rivers, but only few contain information regarding large flooded areas of hydroelectric dams. Most Brazilian hydropower plants have large water reservoirs that may induce significant changes in the local envi...

Woody aboveground biomass mapping of the brazilian savanna with a multi-sensor and machine learning approach.
The tropical savanna in Brazil known as the Cerrado covers circa 23% of the Brazilian territory, but only 3% of this area is protected. High rates of deforestation and degradation in the woodland and forest areas have made the Cerrado the second-largest source of carbon emissions in Brazil. However,...

Nitrous oxide fluxes over establishing biofuel crops: characterization of temporal variability using the cross-wavelet analysis.
Emissions of nitrous oxide (N2O) over croplands are a major source of greenhouse gases to the atmosphere. The precise accounting of sources of N2O is essential to national and global budgets, as well as the understanding of the spatial and temporal relationships with environmental variables such as ...
