Nothing can replace the hands-on experience of a field-based course in the tropics! This is what the Organization for Tropical Studies (OTS) offers through its broad range of Tropical Biology and Ecology graduate level courses in Spanish or English in Costa Rica, and in Portuguese and Spanish in the Brazilian and Peruvian Amazon, respectively*. OTS graduate courses are open to students enrolled in graduate degree programs, with preference given to students at OTS member institutions.

OTS has an outstanding reputation for excellence and has maintained this through rigorous selection and evaluation of instructors, faculty and students.

*To be eligible for a course, an applicant must be fluent in the language in which the course is given.
