...Andrea Giorgi; Giulia Montebovi; Augusto Vitale; Enrico Alleva Our aim in this study was to analyse the effects of early social isolation on the behaviour of a white-handed gibbon ( Hylobates lar ) and at the same time to improve his level of welfare. The subject was a 6-year-old male, isolated...

Gibbons most frequently slept in Dipterocarpaceae and Fabaceae trees and preferentially chose trees taller than average, slept above the mean canopy height and showed a preference for liana-free...

...Dao-Ying Lan Feeding and vocal behaviours of wild black gibbons (Hylobates concolor) were observed from 1987 to 1989 in southwestern Yunnan, notably H. concolor jingdongensis at Mt. Wuliang (24° 18–42’ N, 100° 30–50’ E) in the early spring of 1989. 12 plant species were observed to have been eaten...

On the basis of principal components and discriminant analyses of size-corrected forelimb variables, this study confirms their morphological uniqueness and the more...

...Jeremy Raemaekers The monthly medians of the distances traveled daily by siamang and lar gibbons are negatively correlated with rainfall and positively correlated with the separate and combined abundance of different food categories. The latter correlations indicate that the apes follow a policy...

...R.L. Tilson This study describes how adults of Kloss’s gibbons (Hylobates klossii) inhabiting the central rain forest of Siberut Island, Indonesia, help their offspring achieve reproductive success. Adults of these monogamous apes exclude maturing offspring from the family and territory through...

...Anthony J. Whitten Kloss gibbons are the same size and live in the same type of habitat as several other gibbon species, and consequently its diet would be expected to be similar to its closely related congeners. The diet is described in terms of the weight of food items, faecal remains, and time...

...Jeremy J. Raemaekers; Patricia M. Raemaekers Groups of monogamous, territorial gibbon apes (Hylobates spp.) are thought to interact through their loud calls, but there is little evidence that they do. We present evidence from observation of spontaneous calling and from playback experiments...

...Jeremy Raemaekers Ecological compatibility of sympatric gibbons is achieved by a difference in diet resulting from the effect of differing body sizes on the efficiency of harvesting different foods. In addition, differences in feeding apparatus and body size between the large and small species...

...Julian O. Caldecott Sympatric gibbon species Hylobates lar and H. syndactylus were censused on a mountain in Malaya (West Malaysia). Habitat quality was assessed between 380- and 1,525-m altitudes. H. syndactylus was found to occur up to altitudes higher than does H. lar, and this is discussed...

Reproductive groups are monogamous families with a mean family size of 3.4 individuals (n = 11 families). Such families occupy territories averaging 6.7...

However, the authors find that the dichotomy is not as clear-cut as previous research suggests, since some monkey samples exhibit high LEH frequencies. The authors evaluate...
