JAKARTA, Indonesia – A brand new species of orangutan has been found within the distant jungles of Indonesia, instantly turning into the world’s most endangered nice ape, researchers stated final week.
“It’s the first declaration of a new great ape species in about 100 years,” Ian Singleton, co-author of the examine and director of the Sumatran Orangutan Conservation Programme, advised AFP.
The species, known as ‘Tapanuli orangutan‘, lives within the Batang Toru forest on Sumatra island, and numbers solely about 800 in whole, making it essentially the most endangered nice ape on this planet, Singleton added.
Until just lately, scientists thought there have been solely two genetically distinct varieties of orangutan, Bornean and Sumatran.
But in 1997 researchers on the Australian National University found an remoted inhabitants of the good apes in Batang Toru, south of the recognized habitat for Sumatran orangutans, and scientists started to check the group to see if it was a novel species.
Researchers studied the DNA, skulls and enamel of 33 orangutans killed in human-animal battle earlier than concluding that they’d certainly found a brand new species, giving it the scientific title Pongo tapanuliensis.
Outwardly the Tapanuli orangutan bears a better resemblance to its Bornean counterpart, with cinnamon-coloured fur that’s frizzier than its Sumatran relative. It additionally has a “prominent moustache”, in accordance with the findings revealed within the journal Current Biology.
Its cranium and bone construction are barely totally different from its kin and so is its habits, with the lengthy calls of male orangutans lasting on common 21 seconds longer with a better variety of pulses.
But its tiny inhabitants is below extreme menace from mining, agricultural encroachment, unlawful logging and a proposed hydroelectric dam, which might flood as much as eight p.c of its habitat.
The authors of the examine stated conservation measures must be urgently applied.
“Orangutans reproduce extremely slowly, and if more than one percent of the population is lost annually this will spiral them to extinction,” co-author Serge Wich, professor at Liverpool John Moores University, stated.
Both Sumatran and Bornean orangutans are listed as critically endangered by the International Union for Conservation of Nature (IUCN).
The Sumatran orangutan inhabitants is estimated to be slightly below 15,000, whereas about 54,000 orangutans are thought to reside in Borneo, in accordance with the IUCN.
Rampant logging and the speedy growth of palm oil plantations have been blamed for destroying their jungle habitat. The primates have additionally been attacked by villagers who view them as pests and focused by poachers to be bought as pets. – Rappler.com
