Shark dandruff
How can “shark dandruff” contribute to coral reef conservation?
Julio 06, 2021
Sharks’ bodies are covered with tiny, tooth-like scales called denticles. Shed denticles settle to the ocean floor, where they remain in sediments for years and can be used to understand which sharks lived on a reef in the past.

Critical conservation sites
The highlands of Panama, Central Panama and Darien identified among the 50 Threatened Amphibian Landscapes worldwide
Octubre 19, 2023
A groundbreaking study assessed the extinction risk of more than 8,000 amphibian species worldwide and concluded that two out of five amphibians are threatened.
Evolving diets
Indigenous marine biologist deciphers the evolution of feeding strategies of sister fish species on both sides of the isthmus of Panama
Abril 19, 2024
Through advanced isotopic analyses, Rodnyel Arosemena seeks to understand how fish in the Caribbean and the Pacific that had a common ancestor take advantage of the resources of their different environments today.
Red-eyed treefrogs
Red-eyed treefrog eggs hatch a plan to escape warming temperatures
Julio 12, 2024
A new study from the Smithsonian Tropical Research Institute (STRI) shows that red-eyed treefrog embryos hatch early when exposed to high ammonia levels — an environmental cue that it’s too hot and dry for the eggs to survive.
Leatherback migrations
Leatherback sea turtle behavior: stay near home or set off across the ocean?
Octubre 30, 2024
A new study finds that leatherback sea turtles tend to migrate rather than forage when chlorophyll, primary productivity, and sea surface temperature levels are lower.
