Residents of Puerto Rico’s renowned Monkey Island are hurricane victims too
The important research facility, populated by more than 1,000 monkeys, was hard hit by Hurricane Maria
As thousands of troops and government workers struggle to restore normal life to Puerto Rico, a small group of scientists is racing to save more than 1,000 monkeys whose brains may contain clues to some of the most important mysteries of the human mind.
One of the first places Hurricane Maria hit in the US territory on September 20 was Cayo Santiago, known as Monkey Island, a 16 hectare outcropping off the east coast that is one of the world’s most important sites for research into how primates think, socialise and evolve.
The island’s history as a research centre dates to 1938, when the man known as the father of American primate science brought a population of Indian rhesus macaques to the United States. Clarence Ray Carpenter wanted a place with the perfect mix of isolation and free range, where the monkeys could be studied living much as they do in nature without the difficulties of tracking them through the wild.
Since then the 400 or so macaques have reproduced and expanded their numbers, becoming the world’s most studied free-ranging primate population and something of a living library.
Every animal born on the island is tattooed for easy identification, and the skeleton of every one that has died over nine generations has been saved for future reference. About 100 have had their entire genetic make-up sequenced, and hundreds more have had at least some of their DNA analysed.
Now the university staff and local employees who keep Monkey Island running are frantically ferrying bags of food in a tiny skiff, feeding the macaques a survival diet and trying to reassemble the rainwater collectors and drinking troughs that keep the animals alive in the tropical sun.
Mainland scientists are bringing in equipment from chain saws to a portable pier, funded by tens of thousands of dollars raised so far in university departments and online.
Humans also pose risks for the monkeys. Because the hurricane destroyed the island’s chemical toilet, researchers and workers can stay only until they need a bathroom break: Human waste could start an epidemic that could wipe out the monkeys.
While the rescue effort is heroic, “it’s not sustainable,” said Higham, who is bringing in a container full of supplies, possibly on a ship that would anchor off the island. “They’re doing the best they can do under very difficult conditions, but it needs help and attention.”
