French oil and gas company Total and other energy majors should abandon plans to drill close to the mouth of Brazil's Amazon because of potential risks to the ecosystem of the area, environmental c

Small and medium-scale agriculture is responsible for 80 percent of the deforestation between 2001 and 2015.

Post-FARC development risks could render important eco-systems vulnerable in Colombia.
Guaviare: Colombia’s frontline in the country’s battle to stop deforestation in the Amazon

This time last year, scientists announced the discovery of a reef system at the mouth of the Amazon River — and right from the beginning, they began issuing warnings about companies’ plans to drill

A large fraction of the organic carbon derived from land that is transported through inland waters is decomposed along river systems and emitted to the atmosphere as carbon dioxide (CO2). The Amazon River outgasses nearly as much CO2 as the rainforest sequesters on an annual basis, representing ~25% of global CO2 emissions from inland waters. However, current estimates of CO2 outgassing from the Amazon basin are based on a conservative upscaling of measurements made in the central Amazon, meaning both basin and global scale budgets are likely underestimated.

Deforestation is still increasing exponentially in tropical regions. Some of the worst regions in the world are the Amazon rainforest, South East Asia and Central Africa.

We mapped the inferred long-distance migrations of four species of Amazonian goliath catfishes (Brachyplatystoma rousseauxii, B. platynemum, B. juruense and B. vaillantii) based on the presence of individuals with mature gonads and conducted statistical analysis of the expected long-distance downstream migrations of their larvae and juveniles.

Mosquito-borne viruses threaten public health worldwide. When the ratio of competent vectors to susceptible humans is low enough, the virus’s basic reproductive number (R0) falls below 1.0 (each case generating, on average, <1.0 additional case) and the infection fades out from the population. Conventional mosquito control tactics, however, seldom yield R0 < 1.0.
