A Southern perspective on N deposition and its ecological consequences: should we worry?.
Increased N deposition has been identified as a current global change concern for biodiversity and human health, and excess reactive nitrogen due to human activity has had numerous effects on terrestrial and aquatic ecosystems in the Northern Hemisphere. However, very little is known about the magni...

Modelos baseados em agentes em mudanças de uso e cobertura da terra: o caso da moratória da soja em Santarém.
Os modelos baseados em agentes possibilitam tratar indivíduos, organizações e instituições representando a interação dos atores entre si, e entre os atores com o ambiente. Este trabalho conceitua tais relações e explora o exemplo da moratória da soja, pacto que tem balizado o mercado da so...

Relações entre agentes e células nos modelos de uso e cobertura da terra.
Mudanças de uso e cobertura da terra resultam de complexas interações sociais e biofísicas que podem causar impactos em escalas locais e globais despertando, assim, crescente interesse da comunidade científica. Os modelos baseados em agentes têm se mostrado uma alternativa interessante para re...

Southward moisture transport from Amazonia and rainfall in SE South America.
A large amount of water vapor reaches the rainy South American subtropics coming from the Tropical Atlantic Ocean through a pathway of moisture flow that goes over Amazonia before it veers southwards east of the Andean slopes. While over Amazonia this moisture takes part in the forest's hydrological...

Características do transporte de umidade de grande escala na América do Sul ao longo do ano.
Grande parte das chuvas subtropicais na América do Sul são alimentadas por transporte de umidade de grande escala. No verão grande parte deste escoamento vem do Atlântico tropical e passa sobre a Amazônia antes de rumar para o sul. Neste trabalho buscam-se as principais vias de transporte de um...

From input-output matrixes to agent-based models: a case study on carbon credits in a local economy.
Analytical macroeconomic scenarios are currently the most common approach to assist in the development and evaluation of economic policies. Reproducing and evaluating the results found by analytic models is one major hurdle to be overcome by social simulation on its early development in any specific...

Large-scale changes in precipitation and temperature in South America under climate change – ensemble climate model projections and uncertainties.
Despite current state-of-the art global climate model (GCMs) ability to simulate well the large scale state of the global climate, there is significant variation in future climate projections of precipitation and temperature changes in South America. In order to adequately assess the possible impact...

Local and remote modes of variability of the Atlantic cold Tongue mode.
The dominant modes of coupled ocean-atmosphere variability of the Tropical Atlantic are investigated using observational data, focusing on the cold tongue mode. The seasonal evolution and interannual variability of each mode is obtained from a joint EOF analysis of the three elements of the Bjerknes...
