Primate Ecology: Problem-Oriented Field Studies. Siamangs follow a daily pattern or routine. There now can be no doubt that only the lesser apes—gibbons (genus Hylobates) and siamangs (genus Symphalangus)—can be regarded as true brachiators (Stern and Oxnard 1973; Fleagle, 1974).

This difference might very well be caused by the difference in weight between adult chimpanzees (up to 60 kg in P. troglodytes and no more than 40 kg in P. paniscus). But we know better! Successful treatment for S. scabiei infestation in nonhuman primates has been accomplished with the administration of oral or subcutaneous injection of ivermectin at a dose level of 0.2 mg/kg, repeated in 3 weeks if necessary [318,902]. In known-infected animals, a triple therapeutic treatment, lasting 9–12 months, consists of the oral antibiotics, isoniazid (10 mg/Kg SID) and rifampin (10 mg/Kg SID), and prophylactic use of pyridoxine (vitamin B6) (50 mg SID) to lessen the risk of toxic neuritis and liver damage occurring. Gross lesions include thickening and scaling of the skin and severe alopecia. Chronic periodontitis is common in aged human and nonhuman primates (Page et al., 1975). Cohen and Goldman reviewed the early literature on nonhuman primate periodontal disease and described the periodontal lesions in animals dying of debilitation secondary to enteritis. The Siamang is a medium sized primate that will stand between 2 and 3 feet tall and may weigh as much as 25-30 pounds when grown to adulthood. Now more than ever, we need your support.

Gibbons are monogamous and territorial, and the song duets are assumed to function in territory maintenance and pair bonding. They are frugivorous and folivorous and travel by brachiation, or arm swinging. Therefore, genetic differences could be responsible. Five chimpanzees were successfully treated with 60 g/kg body weight lufenuron mixed in avocado and milk (Dubuis and Lucas, 2003). These very acrobatic primates live in southeast Asia. Cortisone-treated animals showed much less gingival inflammation than controls but much more extensive bone resorption.
