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?
It is much faster to learn to recognize a new prey item from a neighboring species, than to learn by trial and error.
What slows or stops a disease epidemic if the pathogen is still present? It appears that wild frogs are becoming increasingly resistant to the chytrid fungal disease that has decimated amphibian populations around the world.
About 66 million years ago, a radical change on the Earth filled tropical forests with flowers. A new catalog of fossil pollen grains may hold an explanation.
Coral reef fish often see a very different seascape that humans do. Using the evolutionary laboratory created by the Isthmus of Panama, Michele Pierotti is learning exactly how they view their underwater world.
Not only does it take energy to make weapons, it may take even more energy to maintain them. Because leaf-footed bugs drop their legs, it is possible to measure how much energy they allocate to maintaining this appendage that males use to fight other males.
The back and forth relationship between insects and their food plants may drive tropical biodiversity evolution according to work on Barro Colorado Island’s 50 hectare plot.
