Abstract. Fauzi F, Suemarno, Afandhi A, Leksono AS. 2020. Nesting behavior of Bornean immature Orangutan (Pongo pygmaeus wurmbii) in Nyaru Menteng Arboretum School, Palangka Raya, Central Kalimantan, Indonesia. Biodiversitas 21: 2172-2179. This research aimed at analyzing the nesting behavior of Bornean Orangutan (Pongo pygmaeus wurmbii) in Nyaru Menteng Arboretum, Palangka Raya, Central Kalimantan, Indonesia. The objects of observation were the immature orangutan nest, and the type of nest tree. The purposive sampling technique was used because not all immature Orangutan could make a nest. The Focal animal sampling method was used to determine the daily behavior and nets building activity. It involved observing and recording the behavior of five young Orangutans over a certain period of time and analyzing the nest made. The results of the study established that the daily activity of immature Orangutan on an average sequentially ranges from feeding 17.18%, moving 23.92%, resting 26.34%, and social behavior 32.57%. The process of making a nest begins with finding a suitable branch, bending and breaking twigs, and then arranging the twigs and leaves as a mattress. The duration of building a nest was 5.00 to 6.44 minutes, the preferred nest tree was Palaquium xanthochymum and Shorea spp., and the direction of the nest more facing west.

Wildlife surveys were conducted in Usun Apau National Park (UANP), Sarawak from Oct 2017 to Oct 2020. This was the first attempt to document fauna diversity in Usun Apau National Park on the UANP plateau at 1200-1400 m a.s.l. On 17 September 2020, 10 AM, we observed an orangutan individual, Pongo pygmaeus, over a period of one minute at Libut Camp UANP (E: 114039’.546, N: 2052’36.44) at 1,020 m a.s.l. We also recorded four nests and orangutan vocalisation twice. This observation is important for Bornean orangutan conservation as this was the first orangutan sighting in UANP and well outside the species distribution range for in Sarawak.

Abstract. Sapari I, Perwitasari-Farajallah D, Utami Atmoko SS. 2019. The Bornean orangutan (Pongo pygmaeus wurmbii) density in a logging concession of Hulu Belantikan, Central Kalimantan, Indonesia. Biodiversitas 20: 878-883. The Bornean orangutan is currently categorized as a critically endangered species. It is found in natural forests in Borneo, where about 78% of the total population is found outside protected areas, of which 29% is in logging concessions. This study aimed to analyze the density of the orangutan population and the abundance of fruiting plants in a logging concession and Protection Forest (Hutan Lindung) in the Hulu Belantikan forests in Lamandau District, Central Kalimantan, Indonesia. Research and data collection was conducted between December 2013 to October 2014. Orangutan population density was calculated using line transect methodology based on nest counts. Abundance of fruit plants was calculated using the fruit trail method. The highest orangutan density, 4.8 individuals/km2, was found in Protection Forest; and the lowest density, 0.4 individuals/km2, was in [Sopanan] the 2013 logging block. Observations in the logging area indicated that selective logging could alter the structure and gap of the canopy and reduce the proportion of large trees. Changes in forest structure resulted in negative effects on the density of the orangutan population. The remaining degraded forests can still be a valuable resource for the orangutan. As long as the disturbance is not intensive, orangutans will retain access to the less disturbed forest nearby and to forests that are still connected to primary forests. The existence of Protection Forest and old logged-over forests around logging blocks are very important for conservation, providing refugia for orangutans and other species when logging occurs.

The Sebangau National Park is a major stronghold for Bornean Orangutan (Pongo pygmaeus wurmbii) ranging from 6000 – 9000 individuals. In comparison with Bornean Orangutans, very little ecological fieldwork has been conducted to investigate sun bear biology, and there have been no thorough surveys of distribution or population densities. Thus, this study aimed to investigate the basic information on niche overlap between these two endangered species, specifically to quantify their relationship within the small-scale habitat in Punggualas area, SNP. Data was collected and measured during 15 – 21 June 2019; using line transects methods. A total of 6580 m was walked along 8 consecutive transects. Bear and aging sign follow Augeri protocols. A total 18 printed mark-claw and 17 Orangutan nests was measured according to the mentioned methodology. The relationships between signs use binary logistic regressions (StatPlus for Mac) and PCA model (using R), while interspecific relationships use Co-Occurrence modeling, ESP for Windows. The results showed that there is no difference between bear sign and orangutan nest (c2: 26.249; df :1, p-value : 0.001); While the results on habitat selection between transects is failed to reject the null hypothesis (c2 = 0.29; df :1, p-value : 0.490). The Mann-Whitney U test, also confirmed no distinctive overlap between the Orangutan and the Sun Bear (Z: 0.84; p-value: 0.40). The co-occurrence simulations also revealed significant results (C-Score = 1.00), by means both target animals co-existed in the habitat. Obviously, the Orangutan and Sun Bear occupy the same habitat. There is no distinctive overlap between them in terms of tree species selection and having a close interrelationship in terms of feeding ground, whereas the fruiting is not available. The only distinctive difference is that the Bear sign was tend hindering waterlogged terrain.

In the animals in general and nonhuman primates in particular self-medication has been widely reported; however, little is still known about the pharmacological activity of the extracts present in their daily diet. Thein vitroantibacterial activity of the stem, root bark, and leaf extracts of three selected plants on which yellow baboons feed in an unusual manner in Mikumi National Park, Tanzania, was evaluated. Crude plant extracts were tested against Gram positive and Gram negative bacteria of medical and veterinary importance employing a modified agar well diffusion method and Minimum Inhibitory Concentration (MIC) technique. The lowest MIC value for Gram positive strains was 0.31 mg/ml demonstrated byCassia abbreviatassp.abbreviataagainstStaphylococcus aureus(ATCC 25923). The highest susceptibility to the ethanol plant extracts was exhibited byPseudomonas aeruginosa,Escherichia coli,andStaphylococcus aureus,examples of microbes that affect both human and nonhuman primates. These findings demonstrate that the plant extracts fromSterculia africana,Acacia sieberiana,andCassia abbreviatassp.abbreviatahave antibacterial activity and may be used as feed for their prophylactic benefits. Remarkably, the lowest MIC of 0.16 mg/ml was only 16-fold weaker than Gentamicin, a standard drug.
