Organization for Tropical Studies

The Organization for Tropical Studies (OTS) is a research center housed within the University of Costa Rica, San José, as well as a network of three ecological research stations in different parts of the nation. OTS is run by a consortium of universities based at Cornell University in Ithaca, New York. OTS offers a variety of courses (in Spanish and ) for students from the high school level through graduate school, and most of the coursework and research focuses on tropical ecology. The three research stations are located in distinct ecozones and are La Selva Biological Station, a lowland ; Palo Verde Biological Station, a tropical dry forest; and Las Cruces Biological Station, a montane rainforest (including higher-elevation cloud forest) and the site of the Wilson Botanical Garden.
