• Like all gibbons, silvery gibbons lack external tails, have dorsally placed scapulae, and reduced flexibility in their lumbar regions.
• Java's last silvery gibbons are confined to 23 isolated parks and unprotected patches of lowland evergreen rain forests, Andayani said.
• Among the endangered mammal species in the Park there are several primates such as the silvery gibbon, Javan surili and Javan lutung.
• The notes about mammals indicate that there are not many living on Mount Salak, aside from leopards, silvery gibbons, Javan surilis, and sunda pangolins.

• Unlike most other gibbon species ( except for the Javan silvery gibbon, Hylobates moloch ), Kloss's gibbon males and females do not sing duets.
• The more stable of the two silvery gibbon groups, called the western lineage, numbers in the hundreds and lives in and near Gunung Halimun National Park.
• Experts estimate that in the last 25 years, the number of silvery gibbons has plummeted to fewer than 2, 000 and perhaps fewer than 400 from 20, 000.
• Like all gibbon species, the silvery gibbon lives in pairs and stakes out territory that the pair strongly defends; it has relatively small territories of about 42 acres.
• Andayani plans more detailed studies of the region to make sure no silvery gibbons live there and to try to determine when and why the area became a barrier.
• Although the reasons for the initial split between the two lineages are still unknown, the researchers suggest that silvery gibbons find the high montane forests around Gunung Salak inhospitable and refuse to enter them.
• Yet nearly all nine species of gibbon are imperiled through much of their range _ none more than the silvery gibbon, named for its distinctive color and found only on the Indonesian island of Java.
• Melnick and a team of researchers from the United States and Indonesia recently completed a genetic study of silvery gibbons and found that the species split around 100, 000 years ago into two groups, or lineages.
• Andayani, Melnick and three collaborators published their analysis of the silvery gibbons'mitochondrial DNA _ that is, DNA inherited through the mother _ and recommendations for saving the endangered apes in the June 2001 Journal of Conservation Biology.
• The genetic split in silvery gibbons is ancient enough, at 100, 000 years, that the scientists have recommended against a plan to mix the western and central populations unless there is no other way to preserve the species.
• While potentially significant for the long-term survival of silvery gibbons, the research also shows the way genetic, demographic, behavioral and ecological studies are increasingly being used to understand the relationships among groups of animals that have become fragmented and genetically isolated through habitat loss and other human activities.

• If sophisticated genetic studies are to become more than academic records of the path to extinction, scientists say, then officials and people concerned about conservation must commit themselves to preserving land and animals, and scientists and conservationists must find ways to increase legal protection and public support for imperiled animals like the acrobatic silvery gibbon.
