Indigenous organizations, Brazilian congressmen and NGOs were united at the 21st session of the Conference of the Parties (COP21), which took place in Paris of 2015, to condemn a list of actions conducted by both, the Brazilian Federal Executive and Legislative Power, that jeopardize the indigenous rights.
Threshold Responses to Soil Moisture Deficit by Trees and Soil in Tropical Rain Forests: Insights from Field Experiments
Many tropical rain forest regions are at risk of increased future drought. The net effects of drought on forest ecosystem functioning will be substantial if important ecological thresholds are passed. However, understanding and predicting these effects is challenging using observational studies alone. Field-based rainfall exclusion (canopy throughfall exclusion; TFE) experiments can offer mechanistic insight into the response to extended or severe drought and can be used to help improve model-based simulations, which are currently inadequate.
