Bryophytes
Tiny plants in a big changing world
Febrero 22, 2021
The smallest and possibly most ancient terrestrial plants, bryophytes are an important part of our environment, but in the tropics, there is still much to learn about them.
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.
Ancient grapes
New species of grapes are the oldest in the Western Hemisphere
Julio 05, 2024
Ancient, fossilized grape seeds from Panama, Colombia and Peru, provide perspective on the evolution of plants after the extinction of the dinosaurs.
For good measure
A global standard for forest carbon storage requires ground-based measurements
Octubre 04, 2024
To create a global standard for forest carbon storage, we need boots on the ground. The GEO-TREES system of forest plots offers this immediately: establishing a single method for forest carbon estimation at existing on-the-ground forest study sites around the world.
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.
New plant species
Six new species named: 3 from Panama, 3 from Colombia
Diciembre 26, 2024
Plant collections are full of surprises. It may take decades to id plant samples, but it’s worth the effort, especially when some of these species are not known from anywhere else on Earth.
Seeds for a future
A course to learn about the biodiversity of our forests
Marzo 19, 2025
Through a course in dendrology, the study of the taxonomy of woody plants in the absence of flowers or fruits, two experts in forest diversity seek to leave a legacy of knowledge for future generations.
Frog defenders
Bezos Earth Fund Gives $2 Million Grant To Launch Groundbreaking Amphibian Conservation Project Across Latin America
Marzo 20, 2025
A grant from the Bezos Earth Fund to help save 25 frog species through conservation, rewilding, and disease prevention efforts.
Scientist
Roberto Ibañez
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...
