Smithsonian Tropical Research Institute
The Smithsonian Tropical Research Institute is the world’s premier tropical biology research organization, dedicated to increasing understanding of the past, present and future of tropical biodiversity and its relevance to human welfare.
STRI’s basic research is conducted primarily in tropical forest and coral reef ecosystems. STRI scientists discover new organisms, test scientific explanations for ecological adaptation and evolutionary innovation, develop methods to restore degraded lands, train students and promote conservation of tropical ecosystems.
Headquartered in the Republic of Panama, STRI provides:
- A comprehensive tropical sciences library
- A network of research stations in the American tropics
- A station in Kenya protected under international treaties and equipped for sophisticated studies
- Two construction-crane canopy-access systems
STRI also coordinates the Center for Tropical Forest Science–Smithsonian Institution Global Earth Observatories (CTFS–SIGEO), a global network of more than 50 forest research and monitoring stations on five continents.
In 2010, the Smithsonian celebrated 100 years of tropical biology in Panama, commemorating the 1910 Panama Biological Survey. In 1923, entomologists working to eradicate malaria and yellow fever that had crippled French canal building efforts participated in the founding of a field station on Barro Colorado Island in the Panama Canal waterway. In 1946, BCI became a bureau of the Smithsonian dedicated to conducting long-term studies in tropical biology. The organization changed its name to the Smithsonian Tropical Research Institute in 1966 and later established field stations throughout Panama, including marine science laboratories on both coasts.
Budget and Staff
STRI’s operating budget is approximately $23 million. Research at STRI is conducted by an international group of 45 scientists and a full-time staff of 350 employees who also help to host about 1,400 visiting scientists and students each year.
Tropical Diversity and Its Origins—STRI researchers study biodiversity—insects, plants and marine life. Insect sampling in forest canopies suggests that the total number of species on Earth is perhaps 10 million, of which only 2 million have been identified to date. Scientists know little of their biology; yet they may harbor potential sources of new medicines, pest controls and other compounds. Panama has one of the world’s best-known tropical floras, which is now being screened for biomedical compounds. Surveys of little-known marine groups routinely yield new species.
Marine Ecology and Evolution—STRI studies how marine organisms become genetically different over time and how they become reproductively isolated via behavioral and molecular mechanisms. The Panama Canal provides an ideal setting to study invasions by marine organisms.
Ecology and Physiology of Tropical Forests—STRI’s Center for Tropical Forest Science coordinates forest ecology research sites in 23 nations, providing a “Global Observatory” fundamental to understanding how forests change through time in response to changing climate. STRI’s plant physiology program reveals the ways plants respond to environmental stresses. STRI researchers pioneered the use of construction tower cranes to explore tropical forest canopies.
Behavior and Adaptive Evolution—Successful conservation efforts depend on understanding animal behavior, such as how far a bee carries the pollen of a rare orchid or how mammals disperse seeds. STRI’s new neurobiology lab allows researchers to take advantage of Panama’s high insect diversity in a study aimed at understanding the links between brain miniaturization and behavior.
Archaeology, Anthropology and Human Ecology—The accumulated knowledge of tropical people allowed them to flourish, yet their knowledge and environments are rapidly disappearing. By studying the history and development of regional economies and social formation, STRI researchers identify marine and terrestrial conditions that lead either to the depletion of local resources or to their more sustainable use.
Paleoecology—Paleoecologists study the biological consequences of the closing of the Panamanian Isthmus, which separated the Pacific Oceans from the Caribbean Sea and linked North and South America. Work in Colombia documents the first tropical rainforest in the region and its inhabitants, including the world’s biggest snake. A century-long record of coral growth rates shows a decline due to increased sedimentation from coastal runoff, a result of massive deforestation.
STRI research is reported in more than 10,000 scientific journal articles, including many in the journals Science and Nature, as well as in numerous books and edited volumes.
Education and Public Programs
A fellowship program provides training opportunities to students worldwide, and STRI offers advanced graduate studies with affiliated institutions. A bilingual public education and outreach program interprets STRI research and promotes conservation, offering site visits, a weekly newsletter, public lectures, media releases, a nascent videoconferencing program and seminars for decision makers.
