Amazon Basin Tree Rings Hold a Record of the Region’s Rainfall
New research provides a 200-year reconstruction of interannual rainfall in the Amazon basin using oxygen isotopes preserved in tree rings in Ecuador and Bolivia.
Rain Makes Skulls Bigger—in Mice
New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.
A Puzzle Mat for Assembling Colombia’s Geologic History
A new database compiles all the available pieces of information about Colombia’s geochronology, offering scientists a consistent framework in which to view and study the data in a broader context.
Africa’s Earth, Wind, and Fire Keep the Amazon Green
Jet streams sprinkle North African dust over the Amazon, providing the rain forest with much needed nutrients. Changing wind patterns and increasing smoke may shift the system.
Dust in the Wind, Dirt Under Our Feet, and Dunes of Another World
In our April issue of Eos, we follow researchers who get to the root of the Amazon basin’s rich landscape.
