In the Bocas del Toro archipelago, students investigate how tropical island ecosystems respond to development, tourism, and climate change.
On Isla Solarte, a strawberry poison-dart frog perches on a leaf, bright red, thumbnail-sized, unmistakable. Boat to the next island and the same species wears a different color entirely. A few kilometers of open water, and evolution has painted a different animal. The Bocas del Toro archipelago sits where North and South America once collided, and that collision packed coral reefs, mangrove forests, seagrass meadows, and tropical jungle onto islands you can cross on foot. The SFS Center for Tropical Island Biodiversity Studies is based on Isla Colón, where the distance between reef flat and forest canopy is shorter than a morning walk.
Students track those frogs across islands, measuring morphometrics, recording behavior, mapping how land-use change alters the thermal niches each color morph depends on. They snorkel coral nurseries where fragmented corals are being regrown on artificial reef structures, rebuilding what the 2023 bleaching event stripped away. Out of the water, research shifts to governance: visits to Ngöbe Indigenous cooperatives like Oreba and Darklands, where communities are building tourism economies on their own terms. Bocas del Toro is one of the fastest-growing tourism destinations in Latin America. Every study here asks whether the island ecosystems drawing visitors in can survive the development that follows them.
Settlement is spreading across Isla Colón, putting people and wildlife into contact in ways nobody has documented. Students interviewed residents around the island to record how they see it.
Dart frogs ferry their tadpoles to tiny pools cupped inside plants, and the choice of plant shapes how a species uses the forest. Students tracked those choices in a frog found nowhere else.
A 2023 bleaching event killed most of the elkhorn and staghorn colonies SFS had just finished surveying. Students went back to count the fish, and found mixed results across the archipelago.
Cacao here grows under shade, which makes a working farm half a forest. Students compared leaf-litter frog communities across plots to see how much that management holds on to.
The center occupies a former beachfront hotel on Isla Colón. Students live in shared waterfront housing, travel by boat to field sites across the archipelago, and must pass a swim evaluation on arrival: fieldwork involves snorkeling and open-water swimming for up to two hours at a time. The laid-back town of Bocas is a short taxi ride away.
SFS has been part of the Bocas del Toro community since 2012. Students visit Indigenous Ngöbe-Buglé villages, learn traditional fishing and cacao farming practices, explore the Afro-Caribbean cultural traditions of the islands, and trek mangrove islands and rainforest trails to connect habitat health to local policy. Research findings are shared with community partners and Panamanian government agencies at the end of each semester.
Enrolling now for Spring 2027, Summer 2027, and Fall 2027.
