Scientists discover new monkey species, declare it almost extinct
A scientific expedition to the Colombian Amazon has revealed a new species of monkey.
The species of titi monkey (Callicebus caquetensis) is a cat-size creature that is critically endangered because of rapid habitat loss and its small population. The discovery was announced today by the environmental nonprofit group Conservation International.
Research from 30 years ago hinted that a previously unknown primate species might be living in Colombia's Caquet谩 region, near the Ecuadorian and , but violence and insurgent fighting kept the area off limits for decades. It was only in 2008 that scientists Thomas Defler, Marta Bueno and student Javier Garc铆a of the National University of Colombia proved the rumors true.
Garc铆a, a native of Caquet谩, was finally able to travel to the upper Caquet谩 River three years ago, and, using GPS, searching on foot, and listening for calls, he found 13 groups of the new species. Titi monkeys (or zogui zogui as they are called in Spanish) have one of the most complex and use it every morning to mark their territory.
"This discovery is extremely exciting because we had heard about this animal, but for a long time we could not confirm if it was different from other titis. We now know that this is a unique species, and it shows the rich diversity of life that is still to be discovered in the Amazon,鈥� said Defler.
C. caquetensis has grayish-brown hair, but does not have a white bar on its forehead as many other species of Callicebus do. Its long tail is stippled with grey, and it has a bushy red beard around its cheeks. Unlike most primates, Caquet谩 titi monkeys (and probably all titi monkeys) form life-long, , and pairs are often seen sitting on a branch with their tails entwined. They usually have one baby per year. As a new baby arrives, the parents force the oldest baby to leave to allow them to (this is based on information collected from closely related species). The families of this species stick together in groups of about four individuals and can be seen in the trees close to some of the main rivers of Caquet谩.
This newly discovered species is struggling to survive. It is estimated that less than 250 Caquet谩 titi monkeys exist 鈥� a healthy population should be in the thousands. The main reason for this small number is the degradation of the forests in the area, which have been felled for agricultural land. It is very dangerous, and sometimes impossible, for these animals to cross grassy savannah or barbed wire fences to reach other patches of forest.
Both the very small population size and the fragmented habitat should qualify the species for a Critically Endangered (CR) species classification, according to the International Union for Conservation of Nature (IUCN) criteria, which means that it faces an extremely in the wild in the immediate future.
"This discovery is particularly important because it reminds us that we should celebrate the diversity of Earth, but also we must take action now to preserve it," said Jos茅 Vicente Rodr铆guez, head of science at Conservation International in Colombia and president of the Colombia Association of Zoology. "When world leaders meet later this year in Japan for the Convention on Biological Diversity, they must commit to the creation of many more protected areas if we want to ensure the survival of threatened creatures like this in the Amazon and around the world."
