China's fauna exhibits a unique diversity of apes. Unfortunately, the apes are more strongly endangered by extinction in China than in any other country. A research team assembled by anthropologists of Zurich University now conclude that an other ape species has just become extinct in China's Yunnan province.
A scientific team, consisting of members of the Gibbon Conservation Alliance based at Zurich University and the Kunming Institute of Zoology, as well as staff members of the Nangunhe National Nature Reserve, carried out a survey in all Chinese forests reported to support white-handed gibbons (Hylobates lar) during the last 20 years.
The species was last observed in 1988 in the Nangunhe Nature Reserve in south-western Yunnan province, and their loud, melodious calls were last heard in 1992.
