Hunting, Fishing Cause Dramatic Decline in Amazon River Dolphins

By Claire Asher

Populations of two species of river dolphin in the Amazon are halving every decade, according to the results of a twenty-two year survey.

The Amazon rainforest is home to the Amazon river dolphin, or Boto (Inia geoffrensis) and the Tucuxi (Sotalia fluviatilis). But the results of a long-term study published in PLoS ONE show that both of these once abundant aquatic mammals are now in rapid decline in the Brazilian Amazon, likely due to hunting and fishing.

Climate Change Could Bring Drought to Amazon, Greater Rain to Pacific and African Forests

Scientists have discovered another factor that might interact with rising carbon dioxide emissions to influence climate change—tropical forests.

In a study published in Nature Climate Change Friday, researchers found that the way tropical forests interact with increased atmospheric levels of carbon dioxide could alter rainfall patterns, drying out the Amazon rainforest and increasing precipitation in African and Indonesian forests.

Greenpeace Finds Amazon Reef Formation Where Total Plans to Drill for Oil

A team of scientists on board the Greenpeace Esperanza ship have documented the existence of a rhodolith field where French company Total intends to drill for oil, 120km off the northern coast of Brazil.

The finding proves the existence of a reef formation in the area and invalidates Total's Environmental Impact Assessment (EIA), which states the closest reef formation is 8 kilometers (approximately 5 miles) away from one of the oil blocks.

The Power Forest

In the course of writing a book about what free-living animals learn from each other, I find myself on the Tambopata River in southeast Peru. The nearest town is Puerto Maldonado but from there the trip is all upriver. Wheeled vehicles are useless in this forest, and there are none. The surrounding forest has been officially protected with designations of national reserve and national park.
