Fire fuels invasive grass
Octubre 19, 2012
Panama’s infamous canal grass rises from the ashes of fire much faster than trees, complicating reforestation efforts.
Learning from other species
Predators learn to identify prey from other predators
Marzo 21, 2018
It is much faster to learn to recognize a new prey item from a neighboring species, than to learn by trial and error.
What stops mass extinctions?
Lessons From Amphibian Die-off in Panama
Marzo 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.
Abril 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
Mayo 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.
A damselfish moves to Mexico
An Indo-Pacific damselfish takes hold on the other side of the globe
Mayo 23, 2018
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.
Invading the hemisphere
Coastal study from Panama to Alaska discovers where marine invaders fare better
Mayo 30, 2018
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.
Drop Your Weapons!
Autotomy, the shedding of a body part, reveals the hidden cost of conflict
Noviembre 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.
Interesting Chemistry
Innovation by ice cream bean relatives explains biodiversity
Marzo 14, 2019
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.
