Gibbons
What is a gibbon? Gibbons (Hylobatidae) are small arboreal apes that are predominantly found in tropical and sub-tropical forests of South East Asia, South China, Bangladesh and North-East India. True brachiators — animals that swing from tree to tree — these apes are often described as ‘acrobats of the forest’, leaping up to 8 metres between branches and reaching speeds of approximately 56 kil...
متن کاملGibbons-Hawking M-branes
We present new M2 and M5 brane solutions in M-theory based on transverse Gibbons-Hawking spaces. These solutions provide realizations of fully localized type IIA D2/D6 and NS5/D6 brane intersections. One novel feature of these solutions is that the metric function depend on more than two transverse coordinates (unlike all the other previous known solutions). All the solutions have eight preserv...
متن کاملTaxonomy and Evolution of Gibbons
Because the fossil history of gibbons is virtually unknown,1,2 gibbon evolution can only be reconstructed from a comparative analysis of evolutionarily informative characteristics of modern gibbons and, to some degree, of related primate taxa that can be used as outgroups. Several studies have tried to reconstruct gibbon phylogeny, using fur coloration, morphological, vocal, or molecular data.3...
متن کامل3 . Gibbons and hominoid ancestry
Gibbons form a monophyletic group that differs from other hominoid primates, both in behaviour and anatomy. They are found exclusively in eastern Asia, and although evidence from DNA suggests their lineages diverged close to the time of hominoid origins (Goodman et al., 1998), the species array seen today in Asia did not speciate until closer to 6 Mya (Hayashi et al., 1995; Groves, 2001). Their...
متن کاملCaptive Management and Conservation of Gibbons in China and Vietnam, with Special Reference to Crested Gibbons
This paper presents the first census of captive gibbons in selected zoos and other institutions of China and Vietnam. All institutions which were suspected to keep gibbons of the Hylobates concolor group were visited by the author in 1990 and/or 1993. In Chinese institutions, H. hoolock was relatively common, whereas in Vietnam, H. gabriellae was the species most frequently seen in captivity. S...
