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.
My research focuses on how land-cover and climate change affect water movement through soils, weathering, and erosion, and how these, in turn, affect the composition and dispersal of dissolved and solid phases in rivers and trace gases in the atmosphere. Some of my areas of expertise include...
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...
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.
