Lower atmospheric carbon and cooler temperatures may have contributed to the domestication of corn, a new study shows.
Panama’s infamous canal grass rises from the ashes of fire much faster than trees, complicating reforestation efforts.
How will tropical forests respond to a warmer climate with higher atmospheric carbon dioxide concentrations? By growing plants in geodesic domes, Smithsonian scientist Klaus Winter is seeking answers.
What do warmer nights mean for the release of carbon dioxide by tropical forests?
Smithsonian marine biologist Ross Robertson suspects that the regal demoiselle hitched a ride to the Gulf of Mexico on an oil rig. Its outstanding success in its new habitat raises questions about its impact in the Gulf.
Initial results from a massive study comparing marine organisms sampled along the Pacific coast from Alaska to Panama with samples from the Atlantic show that the success of invaders is lopsided.
Native predators could contribute to controlling the abundance and expansion of invasive species
Urban and agricultural development and deforestation along the Mesoamerican Biological Corridor might be generating a new passageway for invasive species adapted to human disturbance.
How do social interactions change in the face of illness? As humans face potential global pandemics we look to nature for examples. Close observation of another highly social animal, the vampire bat, sheds light on how interactions change—or do not change—as individuals become sick.
