What Caused the Open Habitat Transition in the West-Central U.S.?
Between 26-15 My ago, forests covering west-central North America gave way to open, grassy habitats. Now, oxygen isotope records suggest this shift is owed to drier winters and increased aridity.

Upwind Forest Buffers Rondonia Cropland Against Regional Drought
During severe Amazonia droughts when oceanic supply of moisture failed, the magnitude of rainfall reduction over Rondonia was moderated by enhanced moisture supply from upwind forests.
