The results of a new study suggest that past climate changes and sea level fluctuations may have promoted the formation of new species in the Amazon region of South America.

Ice age climate change and ancient flooding—but not barriers created by rivers—may have promoted the evolution of new insect species in the Amazon region of South America, a new study suggests.

Nutrients from the Amazon River's outflow spread well beyond the continental shelf and drive carbon cycling in the tropical ocean, say scientists who conducted a multi-year study. They will publish their results this week online in the journal Proceedings of the National Academy of Sciences (PNAS).

A six-year study of Amazonian small farmers and their responses to climate change shows the farmers are vulnerable to natural catastrophes and risky land use practices, say Indiana University Bloomington anthropologists Eduardo Brondizio and Emilio Moran.

Protected forest strips buffering rivers and streams of the Amazon rainforest should be significantly wider than the current legal requirement, according to pioneering new research by scientists at the University of East Anglia (UEA).

Today, New Zealander Peter Calveley successfully defeated internet bookseller Amazon.com in a suit brought over Amazon's patent for "1-click shopping". The technique, which allows a customer to purchase product without repeatedly entering personal information such as name and address, was seen as a valuable resource to ease customer frustration.
