Abstract

This research was conducted in Gunung Gede Pangrango National Park and aimed to study javan gibbon population  and analyzing problems affecting the existence of the species. The total number of individuals were founded in this research were 42 individuals of 13 groups. The densities of javan gibbon at core zone were 7.14 individuals/km2 and 2.30 groups/km2, whereas at utilization zone were 5.69 individuals/km2 and 1.54 groups/km2. Estimated total individual density were 6.43 individu/km2 whereas group density were 1.93 groups/km2. The estimation of javan gibbon in Gunung Gede Pangrango National Park were 347 individuals in 105 groups. Several problems occured to the habitat and the population of javan gibbon in Gunung Gede Pangrango National Park were: (1) illegal logging; (2) agricultural lan dclearing; (3) tourists and other human activities; (4) illegal hunting; (5) firewoods gathering; (6) non-wood forest product extraction. There were three recommendations to ensure the conservation of javan gibbons in Gunung Gede Pangrango National Park: (1) enhancing the management of Gunung Gede Pangrango National Park areas; (2) managing the activities of local people; and (3) managing tourist program of Gunung Gede Pangrango National Park. Keywords: javan gibbon, population, National Park

Abstract

Long-tailed macaques (Macaca fascicularis: LTMs) are widely distributed, adaptable primates commonly used as animal models in biomedical research. At primate facilities such as the Dramaga Captive Breeding Facility and the Tinjil Island Natural Habitat Breeding Facility at the Primate Research Center, IPB University, LTMs experience varying diets depending on their captive or semi-wild environments. At Dramaga Captive Breeding Facility, LTMs housed in individual and group cages are provided with different feeding regimens, whereas the semi-wild LTMs on Tinjil Island feed primarily on natural food sources with occasional, very modest provisioning of bananas. Our study's objective is to evaluate these diets' influence on the gut microbiota and overall health of LTMs. Through comparative analysis of fecal microbiomes using 16S rRNA sequencing, we identified distinct gut microbiota profiles between captive and semi-wild LTMs. Semi-wild LTMs displayed a predominance of Proteobacteria, notably Succinivibrio, associated with a high-fiber diet derived from wild plant consumption. In contrast, captive LTMs housed in individual and group cages exhibited dominance of Firmicutes and Bacteroidota, respectively. These findings suggest that diet is pivotal in shaping gut bacterial profiles, potentially impacting metabolic functions. Our study provides insight into the relationship between certain diets and gut bacterial composition in LTMs across different breeding facilities at the Primate Research Center, IPB University, thereby offering valuable implications for LTMs' welfare and management strategies.
