Undisturbed tropical rain forests are experiencing more frequent droughts, but the ecosystems are isolated and difficult to assess. Scientists are using remote sensing to expand the depth and scope of monitoring efforts.
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.
New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.
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.
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.
In our April issue of Eos, we follow researchers who get to the root of the Amazon basin’s rich landscape.
In a happy accident, scientists found a potential solution to an atmospheric chemistry mystery. Their findings could be a missing piece in the iodine cycle and in atmospheric models.
At COP26, the Science Panel for the Amazon is emphasizing the need for Indigenous and Local Knowledge to inform scientific and policy recommendations.
The sophisticated new research station will allow for better science on the icy continent.
Newly mapped fast velocity slabs in the lower mantle may be remnants of westward dipping intra-oceanic subduction, before flipping to the present eastward subduction beneath South America at 85 Ma.
