Cayo Santiago Monkeys: Maria relief

Donation protected

Researchers from a set of international universities are working together to save an invaluable scientific resource that was badly damaged in Hurricane Maria— a population of rhesus monkeys living on a remote island — and the staff and facilities that support them.

Cayo Santiago is a small island off the coast of mainland Puerto Rico that’s home to over 1000 free-ranging monkeys. The monkeys have been subjects in scientific research since the 1930s, which makes this site the longest running primate field site in the world.

This unique site and the staff that support it have spearheaded research that cannot be done almost anywhere else. The monkeys roam free on the natural tropical island, but also are so habituated to humans that they can be involved in up-close and personal research--allowing researchers unprecedented access into their daily lives. This microcosm of monkey society has shed light onto questions as diverse as how they think, choose friends, choose mates, and the genetic underpinnings of their complex social behaviors.

But this invaluable resource wound up directly in the path of Hurricane Maria, which devastated Puerto Rico and other parts of the Caribbean. On September 20, the island of monkeys received a direct hit from the Category 4 storm.

A team of international researchers are now working hard to marshall support for this tiny monkey island and the human communities around it. The team includes scholars from New York University, University of Buffalo, University of Exeter, University of Michigan, Univerity of Leipzig, University of Pennsylvania, University of Puerto Rico, University of Washington, and Yale University.

This fragile population somehow weathered this awful storm, but we need to act quickly to save them and the important scientific possibilities they represent. Unless we immediately rebuild the infrastructure on the island as well as the lives of the people that support it, this important resource may disappear.

Funds raised here will directly support the rebuilding of urgently needed infrastructure (e.g. rain water collectors) for the monkeys and will help ensure Cayo Santiago remains the active field site on which future scientific discoveries and the livelihood of the local community depend. Those wishing to support emergency relief funds for the staff and local community directly can donate via the associated campaign found here:

We are working directly with Angie Ruiz-Lambides, Associate Director of the Cayo Santiago Field Station, and Dr. Melween Martínez, Director of the Caribbean Primate Research Center, to identify needs for the macaques on Cayo Santiago and to receive recommendations on how these funds can best be directed.  The funds will be managed by  the 501(c3) Better Research Better Life Foundation (BRBLF), which has been working closely with all the Cayo Santiago scientists and the directors of the Caribbean Primate Research Center. BRBLF will then use this money to purchase supplies and materials as directed by Angie and Dr. Martiínez. By working closely with this not-for-profit foundation, we will be able to maximize your contributions to this fund.
