Trachypithecus geei

Abstract: Six, possibly seven, species of non-human primates occur in Bhutan: slow loris (Nycticebus bengalensis), Assamese macaque (Macaca assamensis), Rhesus macaque (Macaca mulatto), Hanuman langur (Semnopithecus entellus), golden langur (Trachypithecus geei), and capped langur (Trachypithecus pileatus). A variant of the Assamese macaque, named Macaca munzala, has also been recorded there. Natural hybrids between golden and capped langur occur in an area in south-central Bhutan. The Assamese macaque is the most abundant and widespread primate, while slow loris is the least abundant, with a small range in Bhutan. Primates are not hunted for food in Bhutan, there are large areas of contiguous habitats for primates, and there is, besides, a good network of protected areas in the country. Overall, it would appear that primates have a secure future in Bhutan. The main conservation issues come from development, such as the construction of road networks and hydroelectric projects, grazing by domestic stock in...

Abstract: The Golden Langur Conservation Project in Assam, India, was initiated to involve local NGOs and communities in protecting the Endangered golden langur Trachypithecus geei and its habitat on a regional basis within a complex political situation. Since langurs are leaf eaters they are dependent on forests. The Project area, once dominated by militant action and ethnic violence, is in a densely populated area and formerly suffered much illegal deforestation and accompanying reduction in the golden langur population. The Project began with two NGOs and evolved into the formation of a forum of five NGOs focusing on a large proportion of the golden langur range in Assam, and eventually included > 11 newly formed community-based organizations. Each NGO focused on nearby Reserve Forests and their resident langur populations and adjacent human communities. The community-conservation tools used included (1) initial local community awareness campaigns, (2) formation of local Forest Committees and Self Help Groups, (3) a major regional awareness campaign about the golden langur and its forested habitat in the Manas Biosphere Reserve, and (4) creation of a number of village-based Forest Protection Forces. The Golden Langur Conservation Project has resulted in an increase in the total Indian population of golden langurs, control of illegal logging and poaching in two isolated Reserve Forests by formation of a protection force of surrounding village groups, and curtailing illegal logging and increasing forest protection in the Reserve Forests of the Manas Biosphere Reserve by the formation of 10 tribal, government-sanctioned volunteer Forest Protection Forces. The Project created an atmosphere of community awareness of the golden langur and its forests and community interest within the region, with communities taking responsibility for protection of regional forests.

Abstract: The importance of the ecology of Japanese macaques lies in the fact that they are typical “temperate primates.” Temperate forest is a marginal habitat for primates, as the center of the primate distribution is tropical rainforest. If we define the border between temperate and tropical areas as the Tropics of Cancer and Capricorn, approximately 20 genera of eight families of primates are distributed in temperate areas, including East Asia (Japan and China), South Asia (Bhutan, Nepal, India, Afghanistan, Pakistan, and Bangladesh), South Africa, North Africa (Morocco and Algeria), Madagascar, and South America (Argentina). Among them, ten species are distributed more widely in temperate than in tropical regions, including five species of macaques (Macaca fuscata, Macaca cyclopis, Macaca mulatta, Macaca thibetana, and Macaca sinica), three species of golden monkeys (Rhinopithecus bieti, Rhinopithecus roxellana, and Rhinopithecus brelichi), and capped and golden langurs (Trachypithecus pileatus and Trachypithecus geei). Among them, five species (Japanese and Barbary macaques, Sichuan and Guizhou golden monkeys, and golden langurs) are distributed exclusively in temperate regions (Fleagle 1999). Japanese macaques are undoubtedly the best studied temperate primate species.

Abstract: Aim: The study was conducted to know the parasitic infestation in captive non human primates of Assam State Zoo. Materials and Methods: A total of twenty two faecal samples from non human primates of different species viz. Slow loris (Nycticebus coucang) (3), Pig tailed macaque (Macaca nemestrina) (3), Stump-tailed macaque (Macaca arctoides) (5), Assamese macaque (Macaca assamensis) (1), Bonnet macaque (Macaca radiata) (1), Golden langur (Trachypithecus geei) (6) and Hoolock gibbon (Hylobates hoolock) (3) were analysed from August, 2009 to December, 2009 by using routine sedimentation and floatation techniques as described by Georgi (1985). Identification of parasitic ova was carried out as described by Soulsby (1982) and Wallach and Boever (1983). Results: Out of 22 faecal samples examined, 1 (20%) in stump-tailed macaque was found positive for Oesophagostomum spp. and 1(16.67%) in golden langur and 1 (33.33%) in hoolock gibbon, were found positive for the presence of Trichuris spp. Conclusion: Incidence of parasitic infection was 13.63% in captive non human primates of Assam State Zoo.
