A three year genetic study by wildlife geneticists from Cardiff School of Biosciences has shown a population collapse in the Bornean orang-utan....... The population has declined up to one hundred fold since the late 19th Century, coinciding with the arrival of colonial powers on the island of Borneo and accelerated timber extraction. The research is among the first to link species decline with...Genetic study shows humans have pushed orangutans to the brink of extinction
A new study published in the open-access journal PLoS Biology shows strong genetic evidence of a catastrophic collapse in orangutan populations living in the fragmented forests of the Kinabatangan Wildlife Sanctuary in Sabah, Malaysia. Benoit Goossens, Louns Chikhi, ... Michael Bruford, and their colleagues report that the collapse occurred within the past hundred years, and most likely within t...From the hundreds of thousands of orangutans that once ranged throughout southeast Asia, only two orangutan species now inhabit just two countries: Indonesia and Malaysia. The Sumatran orangutan is listed as critically endangered, the Bornean, endangered.
