Combined exposure to hydroelectric expansion, climate change and forest loss jeopardies amphibians in the Brazilian Amazon.
Aim: Human-driven impacts constantly threat amphibians, even in largely protected regions such as the Amazon. The Brazilian Amazon is home to a great diversity of amphibians, several of them currently threatened with extinction. We investigated how climate change, deforestation and establishment of ...- por Portal Padrão

Impact of intensive fish farming on methane emission in a tropical hydropower reservoir.
Fisheries and aquaculture are important sources of food for hundreds of millions of people around the world. World fish production is projected to increase by 15% in the next 10 years, reaching around 200 million tonnes per year. The main driver of this increase will be based on fish farming managem...- por Portal Padrão

Biomass burning emission disturbances of isoprene oxidation in a tropical forest.
We present a characterization of the chemical composition of the atmosphere of the Brazilian Amazon rainforest based on trace gas measurements carried out during the South AMerican Biomass Burning Analysis (SAMBBA) airborne experiment in September 2012. We analyzed the observations of primary biomas...- por Portal Padrão

Climatic diagnostics associated with anomalous lightning incidence during the summer 2012/2013 in Southeast Brazil.
The State of São Paulo in Southeast Brazil experienced during the 2012/2013 summer one of the most severe electrical storm events in recent years, causing various impacts to society, e.g. fires and fatalities. Thus, the objective of this work is to understand which mechanisms and climatic variabili...- por Portal Padrão

Unfolding long-term late pleistocene–holocene disturbances of forest communities in the southwestern Amazonian lowlands.
Linking the distribution of plant species to geology has generally been biased by the over-simplification of landscape evolution and the lack of understanding of complex geological processes. The Amazonian lowlands have forests in different successional stages, and a growing perception is that such ...- por Portal Padrão

Calibration and combination of monthly near-surface temperature and precipitation predictions over Europe.
A Bayesian method known as the Forecast Assimilation (FA) was used to calibrate and combine monthly near-surface temperature and precipitation outputs from seasonal dynamical forecast systems. The simple multimodel (SMM), a method that combines predictions with equal weights, was used as a benchmark...- por Portal Padrão

Spatial and temporal changes in the land use and cover of the Paraíba Valley in São Paulo, Brazil: development of future scenarios.
The Paraíba Valley in São Paulo, Brazil, is marked by great transformations. The Brazilian economic cycles changed this region and transformed it into a great mosaic of pastures, forest fragments, and urban areas. Temporal studies on land use and cover have given information on these changes and e...- por Portal Padrão

Towards a reproducible LULC hierarchical class legend for use in the southwest of Pará State, Brazil: a comparison with remote sensing data-driven hierarchies.
Land Use and Land Cover (LULC) classes defined by subjective criteria can diminish the significance of a study, hindering the reproducibility and the comparison of results with other studies. Having a standard legend for a given study area and objective could benefit a group of researchers focused o...- por Portal Padrão

A generic pixel-to-point comparison for simulated large-scale ecosystem properties and ground-based observations: an example from the Amazon region.
Comparing model output and observed data is an important step for assessing model performance and quality of simulation results. However, such comparisons are often hampered by differences in spatial scales between local point observations and large-scale simulations of grid cells or pixels. In this...- por Portal Padrão
