Climate benefits of Amazon secondary forests—recent advances and research needs
A quarter of the deforested Amazon has regrown as secondary tropical forest and yet the climatic importance of these complex regenerating landscapes is only beginning to be recognised. Advances in satellite remote-sensing have transformed our ability to detect and...
Apresentação – Certificação orgânica participativa
Apresentação integrante da vídeo-aula 1 sobre certificação orgânica participativa dentro do projeto "Mercados Verdes e Consumo Sustentável". Este material faz parte do Módulo Laranja, chamado Diferenciação de Mercados, um dos sete temas que compõem o...
Opposite latitudinal patterns for bird and arthropod predation revealed in experiments with differently colored artificial prey
The strength of biotic interactions is generally thought to increase toward the equator, but support for this hypothesis is contradictory. We explored whether predator attacks on artificial prey of eight different colors vary among climates and whether this...
Solving Brazil’s land use puzzle: Increasing production and slowing Amazon deforestation
Brazil has become an agricultural powerhouse, producing roughly 30 % of the world’s soy and 15 % of its beef by 2013 – yet historically much of that growth has come at the expense of its native ecosystems. Since 1985, pastures and croplands have replaced nearly 65...

Biological Nitrogen Fixation Does Not Replace Nitrogen Losses After Forest Fires in the Southeastern Amazon
Tropical forest fires have become more common due to interactions between deforestation, land clearing, and drought. Forest recovery following fires may be limited by nitrogen. Biological nitrogen fixation (BNF) is the main pathway for new nitrogen (N) to enter...
Droughts Amplify Differences Between the Energy Balance Components of Amazon Forests and Croplands
Droughts can exert a strong influence on the regional energy balance of the Amazon and Cerrado, as can the replacement of native vegetation by croplands. What remains unclear is how these two forcing factors interact and whether land cover changes fundamentally...
