Abstract

Lutung kelabu (Trachypithecus cristatus) merupakan salah satu primata dalam famili Cercopithecidae yang tersebar di Kalimantan dan Sumatera. Habitatnya yaitu daerah pesisir mangrove, tepi pantai dan riparian. Saat ini, penelitian lutung kelabu banyak dilakukan di pulau Sumatera, namun masih kurang informasi di pulau Kalimantan. Salah satu habitat yang menarik adalah hutan mangrove hasil restorasi. Penelitian ini bertujuan untuk mengetahui distribusi dan kepadatan populasi lutung kelabu, serta mengindentifikasi jenis pakannya di Kelurahan Handil Baru, Kecaamatan Samboja, Kabupaten Kutai Kertanegara, Kalimantan Timur. Informasi awal yang dapat digali adalah berupa kajian ekologi. Kepadatan populasi diketahui melalui pengamatan langsung dengan metode Concentration Count, sedangkan distribusi lutung dianalisis menggunakan software ArcGIS ver. 10.4. Penelitian ini menemukan tiga kelompok lutung kelabu pada kawasan mangrove Kelurahan Handil Baru, yang tersebar di wilayah Handil Baru Muara, Sungai Raden dan Sungai Mantri. Kepadatan populasi rata-rata yaitu sebesar 6,63 individu/ha di Handil Baru Muara 2,65 individu/ha di Sungai Raden dan 0,72 individu/ha di Sungai Mantri, dengan jumlah individu per kelompok antara 17-24 individu. Terdapat 22 jenis tumbuhan sebagai sumber pakan lutung kelabu. Kepadatan populasi dipengaruhi oleh luas penggunaan habitat, jumlah individu pada lokasi tersebut, serta ketersediaan pakan. Penelitian ini dapat digunakan sebagai referensi pengelolaan habitat maupun pengembangan kawasan yang berkontribusi bagi kelestarian lutung kelabu.

Abstract

Tonkean macaques are one of seven endemic macaque species on Sulawesi Island. Feeding management in captivity should pay attention to the quality, palatability, and feeding behavior patterns of animals. The goal of this study was to compare the feeding behavior of two social groups of Tonkean macaques at Schmutzer Primates Center (SPC) and Ragunan Zoo (RZ) with different captive management, which was expected to affect feeding behavior. Ad libitum sampling was used to observe daily behavior and hierarchy, while focal animal sampling was used to observe feeding behavior and feed preference. Data were collected from September 2013 until March 2014 with a total of 495 hours of observations. There were significant differences between the daily behavior of two groups of Tonkean macaques. Resting behavior was dominant in RZ group with non-enrichment feed cage, while feeding behavior was more common in the SPC group with an enrichment feed cage. The SPC group spent most of their feeding time in searching for feed, while choosing, carrying and refusing were greater in the RZ group. Both Tonkean macaque groups showed individual dominance in their feeding behavior. Provisioned feed in both locations had different diversity and preference values. The selection of feed required was based on preference values with attention to Tonkean macaques’ feed in nature. Cage construction, such as the SPC cage, was able to reduce abnormal behavior exhibited by individuals.

Abstract

The Sulawesi black-crested macaque (Macaca nigra) is an endemic primate of North Sulawesi that is categorized as critically endangered (IUCN 2015). Endoparasite contributes to the decline of M.nigra. Therefore, this study aims to determine the prevalence of endoparasites in the Sulawesi black-crested macaque (M. nigra). We collected 80 fresh fecal samples representing all sex from the two habituated groups. We analyzed them using the direct examination technique (0.9% NaCl, iodine, methylene blue) and flotation technique with the modified McMaster test. A total of 15 endoparasite taxa were recorded and 78 of 80 samples were infected with at least one or several endoparasite taxa. Around 93.75% (75/80) samples were positive for protozoa (Balantidium sp., Entamoeba sp., Giardia sp., and Isospora sp.) and 88.75% (71/80) samples were positive for helminths (Ancylostoma sp., Strongyloides sp., Haemonchus sp., Trichuris sp., Trichostrongylus sp., Ascarid sp., Diphyllobothrium sp., Echinococcus sp., Hymenolepis sp., Schistosoma japonicum and Schistosoma mekongi). The abundance of protozoa was higher than helminth, although the number of helminth taxon (11) was higher. The average temperature and monthly rainfall did not affect the number of endoparasites (EPG). The prevalence was higher in females than males due to different social styles; female crested macaques are more tolerant than males. The group with a larger number of individuals had a higher prevalence of endoparasites. These results confirm the presence and high diversity of gastrointestinal endoparasites in M. nigra, which can help to understand transmission dynamics and zoonotic potential, as well as to consider conservation policies.

Abstract

Pregnancy and lactation are reproductive phases that require large amounts of energy. Females in the reproductive period need good quality and quantity of food to provide nutrition for the fetus, milk production and child care. The mother will adapt to changes in behavior patterns and food type to meet these needs. The influence of parity and environmental conditions can affect the behavior patterns of females. During pregnancy, the Macaca nigra is known to have different proportion of activities in each period, while the behavior during the lactation phase in each mester is unknown. Therefore, this study aimed to analyze the behavior patterns in each mester and the food selection of Macaca nigra during the pregnancy and lactation phases, as well as the influence of female parity and environmental toward the behavior patterns. There were 39 females Macaca nigra observed from two groups from August 2018 to July 2019. An instantaneous focal sampling method was performed to observe females’ daily activities, continuous focal sampling to monitor food types and a selectivity index to analyze food type preferences. The results showed that the female Macaca nigra pattern was influenced by the reproductive phase, female parity and environmental conditions. Females at the end of the pregnancy and lactation phases had a high proportion of feeding and eat more arthropods. Primiparous females mostly performed resting activities. Food preference was influenced by reproductive factors and food availability. The choice of fruit could be affected by fruit availability, and their favorite food was D. mangiferum and Euginia sp.

Abstract

Tinjil Island was established as a Natural Habitat Breeding Facility for long-tailed macaques (Macaca fascicularis) in 1997. Between February 1998 and January 2007, 603 (61 males and 542 females) simian retrovirus (SRV) free long-tailed macaques were introduced to the island on the south coast of West Java and function as a primate resource and conservation program. To date, 3256 progenies have been harvested and used as the animal model. Therefore, it is necessary to survey the current population of the long-tailed macaques to evaluate whether the population is still under the island’s carrying capacity. This research aims to identify the population estimate of long-tailed macaques currently occupying the island. The observation was conducted in July 2021 using line transect sampling starting from 07.00 AM and 01.00 PM. Twelve observations were conducted during the study using CD and ES transects. CD (Chuck Darsono) and ES (Emil Salim) are the two longest trails on the island and represent the names of the people who initiated the captive breeding of Tinjil Island. The estimated group density of the long-tailed macaques on Tinjil Island is 13.46 groups/km2, while the estimated population density is 111.04 individuals/km2. The population estimated on the island is 627.38±23.53 individuals. The number indicates that the population is still under carrying capacity.

Abstract

Indonesia is one of a country with high biodiversity and genetic resources. One of them is Madura cattle that derived from crossing between exotic cattle, namely zebu cattle with local Indonesian cattle, namely Bali cattle. Branched-chain alpha-keto acid dehydrogenase is an enzyme complex that metabolizes branched chain amino acids, namely valine, leucine and isoleucine. This study aimed to analyze exons 2-3 variation of the BCKDHA gene and its flanking region in Madura cattle. The sequences of it were obtained using DNA sequencing techniques. A total of seven variations were found, one variation located in the flanking region adjacent to the 5' end of exon 2 of the BCKDHA gene. The A392G variation found in exon 3 does not cause any amino acid changes. There is no variation found in exon 2, it indicates that the exon regions of BCKDHA gene are more conserved than introns in the Madura cattle.

Abstract

The Bornean orang-utan (Pongo pygmaeus wurmbii) release process at Lamandau Wildlife Reserve applies the soft-release method. In this method, there is still provisioning additional food on the feeding site by human. The existence of camp release and feeding sites in the vicinity of release forests is assumed to have an impact on orang-utans’ activity patterns. This assumption is related to the principle of releasing them into their natural forest habitat, namely by reducing direct interaction between humans and orang-utans. The aims of this research were: (i) to measure the intensities of orang-utan presence on camp and feeding site, (ii) to analyze the correlation between phenology and orang-utan’s presence on camp and feeding site, and (iii) to assess orang-utan’s activity budgets, diet composition, and vertical used on camp, feeding site, and forest. Activity budgets of five group orang-utans with different categories based on age and sex were compared using the focal animal sampling method and instantaneous records. The analysis showed no correlation between the intensities of orang-utan presence and phenology. However, there were significant differences in activity patterns between adult and adolescent orang-utans. The findings revealed that adult orang-utans activity pattern tended to be high in resting at all observation locations while adolescents spending more their activity for feeding. Orang-utans at 0-10 m of height classes tend to do more activity. Almost all orang-utans feed on a non-forest diet (45-67%) in the camp release, feeding site, and surrounding. We assumed that the existence of a camp release and feeding site near the release point are affecting factors in a successful reintroduction of ex-rehabilitate orang-utans.

Abstract

Tinjil Island is a semi-natural breeding facility for long-tailed macaques (Macaca fascicularis) managed by Primate Research Center, IPB University, located at the southern of Java Island and surrounded by the Indian Ocean. Long-tailed macaques are considered frugivorous even though they are well-known for their flexible diet. This study aims to analyse the vegetation supporting the population of long-tailed macaques. Data were collected from six tracks using square sampling plots with the size of 20 m x 20 m for trees as the main plot, inside the main plot were square subplots consisting of 10 m x 10 m for poles, 5 m x 5 m for saplings, and 2 m x 2 m for seedlings. The Important Value Index (IVI) was calculated for each level of vegetation. Hanjuang (Dracaena elliptica) dominated the seedlings with 29.35%, followed by Kampis (Hernandia peltata) with 18.73%, and Kalapari (Pongamia pinnata) with 13.73%. Hanjuang (Dracaena elliptica) also dominated the saplings with 26.83%, followed by Pancal (Syzygium antisepticum) with 19.19%, and Laban (Vitex pubescens) with 12.30%. The poles were dominated by Ki Cau (Dolichandrone spathacea) as high as 59.28%, while Waru (Thespesia populnea) and Ki Ciat (Ficus septica) dominated at 40.47% and 36.15%, respectively. Kampis (Hernandia peltata) dominated the trees with 39.28%, followed by Ki Ara (Ficus glomerata) with 35.56%, and Ki Langir (Dysoxylum amooroides) with 28.70%. Species found on Tinjil Island are mostly Moraceae (9.84%) and Fabaceae (9.84%), followed by Malvaceae (8.20%), Euphorbiaceae (4.92%), Myrtaceae (4.92%), and Anacardiaceae (4.92%). The vegetation in Tinjil Island supports the livelihood of long-tailed macaques on the island because they have an abundance of food and staple food such as figs to help them fulfil the energy needed to survive and reproduce.

Abstract

Mosquito fish (Gambusia affinis) is a species often used as a bioindicator because it has high adaptability to water quality changes. Linear alkylbenzene sulfonate (LAS) is a surfactant often found in waters and can cause death for the biota that lives in it. This study aimed to analyze the impact of LAS surfactant on the survival of mosquito fish and to determine the minimum concentration of LAS surfactant that can cause death and tissue damage. Research conducted during April 2022 using 500 mosquito fishes. We did several tests, including a lethal toxicity test to find out the concentration of LAS surfactant that can cause death and tissue damage. The results showed that the LC50 values of LAS surfactants at exposure times of 24, 48, 72, and 96 hours were 7.64, 7.43, 7.29, and 6.83 mg/L, respectively. Mosquito fish blood glucose levels at LAS concentrations of 0, 2.65, 4.30, 6.97, and 11.3 were 56, 75, 79.6, 95, and 95.6 mg/dl. Exposure to LAS surfactant in mosquito fish can cause gill damage in the form of edema, lamella fusion, hyperplasia, lamellae epithelium swelling, and gill filaments necrosis. Another damage occurs to the liver in the form of blockage of blood vessels and sinusoids, hyperplasia, widening of the hepatic sinusoid gap, fat accumulation, and necrosis of hepatocytes.

Abstract

The endangered javan gibbon (Hylobates moloch) has been threaten by massive habitat loss and fragmentation in Java. The survival of the second largest population which inhabited unprotected Dieng mountains faced greater risk to habitat conversion and fragmentation. The landscape-level habitat monitoring using spatiotemporal quantification is crucial as a baseline data for javan gibbon conservation. Here, the land-use and land-cover (LULC) change of the Javan gibbon habitat during 1994–2009–2021 and its fragmentation in the Dieng mountains were quantified. This study revealed there were no significant decline in the total of forest. However, its quality was degraded in the interior of forest block. The forest has more fragmented from large patches into smaller patches and increased forest edge. The higher fragmentation happened in the areas that traversed by road. Six suitable forest blocks were identified with varying level of connectivity. Protection and restoration both in the forest and in the interior forest is immediate need, especially in the main forest block. The extra effort is also crucial in the connected forest but traversed by road. The blocks which closely isolated by road could be potentially reconnected by artificial canopy bridge, while the other distantly isolated block might need habitat restoration for corridor.
