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.
Students in Bocas del Toro helped Smithsonian researchers collect environmental data to better understand what factors influence the proliferation of algal deposits in the largest island of the archipelago
A species of tree fern found only in Panama uses ‘zombie leaves’ or reanimated dead leaf fronds, and turns them into root structures that feed the mother plant.
What started as a student summer job, became Anibal Velarde’s life’s work. Over fifty years later, he is still at the Smithsonian
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.
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.
A grant from the Bezos Earth Fund to help save 25 frog species through conservation, rewilding, and disease prevention efforts.
I specialize in forest ecosystem ecology, global change ecology, and climate protection through forest conservation. My approach combines data synthesis and analysis, quantitative ecology, and field research and focuses on understanding how climate — and climate change — shape ecosystems, and...
My primary research focus is on Panamanian frogs that are likely extinct in the wild due to a fungal infection but are kept alive in captive breeding programs in Panama and the United States. Our lab has collected founding individuals for these amphibian colonies, devised methods to sustainably...
