Do pests keep rare tree species from becoming common?
Julio 15, 2012
A five-year, $2-million grant will help test the hypothesis that rare trees are more susceptible to pathogens than common trees on Barro Colorado Island.
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.
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.
Dermal Disruption
Amphibian skin bacteria is more diverse in cold and variable environments according to global survey
Febrero 27, 2019
Frog researchers swabbed 205 amphibian species to better understand the ecology of their skin bacteria. Which environmental factors influence the makeup of their microbiomes?
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.
