Two unrelated butterfly species may develop the same wing pattern, but along different pathways
An international team of scientists working with Heliconius butterflies at the Smithsonian Tropical Research Institute in Panama was faced with a mystery: How do pairs of unrelated butterflies from Peru to Costa Rica evolve nearly the same wing-color patterns over and over again? The answer, ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

Red-eyed tree frog
A red-eyed tree frog (Agalychnis callidryas) captured in Panama. A new study reports that some Central American frog species are recovering from the 40-year decline they've been under, perhaps because they have better defenses against a deadly fungal pathogen.

There's more going on with frog skin than the proverbial warts
Researchers collected samples of seven frog species from the Chiriquà highlands in Panama to find out what kind of skin bacteria they harbored. Studying the skin bacteria of Panamanian frogs may lead to the development of alternative drugs to treat the fungi causing aspergillosis in humans, which ...This is an NSF Multimedia Gallery item.

Coral reefs' decline pre-date climate change decline from climate change
Tree oyster Dendrostrea frons attached to staghorn coral Acropora cervicornis. These two specis were the dominant bivalve and coral, respectively, on reefs in Bocas del Toro, Panama, until they began to decline at least 50 years ago, in conjunction with large-scale land ...This is an NSF Multimedia Gallery item.

Exposing cacao tree seedlings to leaf litter from healthy cacao adults significantly reduced seedlin
Those who crave brownies or hot cocoa may be happy to hear that heroes too small to be seen may help to protect the world's chocolate supply. Scientists at the Smithsonian Tropical Research Institute (STRI) in Panama found that exposing baby cacao plants to microbes from healthy adult cacao plants ...This is an NSF Multimedia Gallery item.

Diversity of parental strategies in glassfrogs (Image 9)
A male glassfrog (Hyalinobatrachium fleischmanni) in Rio Frijoles, Panama, cares for well-developed embryos that have already delayed hatching about one week past hatching competence. Researchers studying diversity of parental strategies in glassfrogs found that species with male care ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)
