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.
Behavioral evolution
First report of stone tool use by Cebus Monkeys
July 09, 2018
White-faced capuchin monkeys in Panama’s Coiba National Park habitually use hammer and anvil stones to break hermit crab shells, snail shells, coconuts and other food items, according to visiting scientists at the Smithsonian Tropical Research Institute (STRI). This is the first report of habitual stone-tool use by Cebus monkeys.

Tropical Forest Seeds Have Three Survival Strategies
August 03, 2018
From tiny banana seeds to giant coconuts, it’s tough for seeds to survive in tropical soils where they are under attack by fungi, bacteria, insects and animals. By understanding how seeds defend themselves, tropical biologists contribute to reforestation, crop management and sustainable agriculture in the tropics.

January 18, 2019
A small bump in the ear canal of skulls from burials near the Gulf of Panama, may indicate that ancient coastal residents dove in icy waters to recover pearls and valuable orange Spondylus shells.
Approach angle
Bats use leaves as mirrors to find their prey in the dark
August 09, 2019
Bats can find motionless insects on leaves in the dark. This was thought to be impossible, because the acoustic camouflage provided by the leaves should confuse their echolocation system. Inga Geipel and colleagues discovered how they overcome this problem.

Bats use private and social information as they hunt
October 04, 2019
As some of the most savvy and sophisticated predators out there, bats eavesdrop on their prey and even on other bats to collect a wide variety of information about their prey.
