What stops mass extinctions?
Lessons From Amphibian Die-off in Panama
March 30, 2018
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.
Flowers from Darkness
“Tropical forests are the result of an accident of history.” - Carlos Jaramillo.
April 23, 2018
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.
Through the eyes of a fish
A tale of communication on coral reefs
May 22, 2018
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.
Drop Your Weapons!
Autotomy, the shedding of a body part, reveals the hidden cost of conflict
November 16, 2018
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.

Where science meets music: a banjo player listens for the songs of katydids
April 17, 2019
What do playing the banjo and recording katydids have in common? We join Sharon Martinson on Barro Colorado Island to find out.
Platypus crab
Fossil crab reveals a new branch in the tree of life
April 25, 2019
By taking on characteristics from another, younger stage in its life-cycle, this fossil crab was probably able to adapt to new conditions.
