Smithsonian scientists connect climate change, origins of agriculture in Mexico

New charcoal and plant microfossil evidence from Mexicos Central Balsas valley links a pivotal cultural shift, crop domestication in the New World, to local and regional environmental history. Agriculture in the Balsas valley originated and diversified during the warm, wet, postglacial period following the much cooler and drier climate in the final phases of the last ice age. A significant dry p...

Drought limits tropical plant distributions, scientists at the Smithsonian report

Drought tolerance is a critical determinant of tropical plant distributions, researchers working at the Smithsonian Tropical Research Institute in Panama report in the journal Nature, May 3.
