Abstract

Indonesia has two of the three amphibian orders, Gymnophiona and Anura. Frogs in Indonesia have ten families. In West Java, there are 28 Anura species from six families. In general, frog habitats are very diverse and can be found in urban areas. However, the distribution in the IPB Dramaga campus, especially in the lake ecosystem is still unknown. Therefore, this research aims to determine the diversity and distribution of the Anura order in the Lake Ecosystem of IPB Dramaga. The method used is the Visual Encounter Survey (VES). The research locations are the three lakes ecosystem at IPB Dramaga (SDGs, Inspirasi Lake, LSI). This research recorded eight species, including Duttaphrynus melanostictus, Ingerophrynus biporcatus, Fejervarya cancrivora, Limnonectes macrodon, Hylarana erythraea, Amnirana nicobariensis, Microhyla achatina, and Polypedates leucomystax. Species D. melanostictus and F. cancrivora are distributed throughout the lake. This study recorded that the Shannon-Wiener diversity in the IPB Dramaga Lake ecosystem (SDGs, Telaga Inspirasi, LSI) was in the medium category (1.28–1.71). Brillouin Diversity Index is in the high category (1.18– 1.50). The evenness index (0.82–0.92) was close to even. Simpson's Dominance Index (0.21–0.30) and Margalef's Species Richness (1.17–1.91) were low.

Abstract

Gibbon (Hylobates funereus) is one of the endemic primates of Borneo Island. H. funereus is declared as endangered species in the IUCN Red List 2020. One of the threats is the loss of habitat caused by deforestation for palm oil plantations. The aim of the research is to assess population density and to estimate population of gibbons at Long Ayap Forest, Berau Regency, East Kalimantan Province. Observation is conducted using strip transect sampling method, carried out at three forest blocks at palm oil plantation of PT Mulia Inti Perkasa (MIP) from September to December 2022 with the total of 27 repetitions. The total gibbon population density is 11-11,96 individuals/km2. Estimation of gibbon population at Long Ayap Forest, Berau Regency, East Kalimantan Province is 17.82 individuals.

Abstract

Identifying floral resources used by honey bees and stingless bees is essential for sustainable beekeeping and understanding pollination ecology. This study compared the diversity of floral resources utilized by the honey bee Apis cerana and stingless bees Geniotrigona thoracica and Heterotrigona itama based on pollen in honey. Bee colonies were in the same Flora Nauli Beekeeping area, Pematang Siantar, North Sumatra, Indonesia, ensuring equal access to similar surrounding floral resources. Honey samples were collected, and pollen grains were extracted, acetolysed, and analyzed by counting 1,200 grains to determine frequency classes. Pollen diversity was calculated using the Shannon–Wiener index (H′). Stingless bee honey contained more diverse pollen than A. cerana, which only contained pollen from the Arecaceae family. Heterotrigona itama and G. thoracica honey contained pollen from 20 and 11 plant families, respectively. Each species had a distinct predominant pollen type (>45%): Cocos nucifera (A. cerana), Sapotaceae type (G. thoracica), and Casuarinaceae type (H. itama). A higher pollen diversity index was also observed in H. itama (1.05-1.83) than in G. thoracica (0.34–1.64) and A. cerana (0.66). These results indicate that stingless bees are more generalist than honey bees, highlighting their ecological role in supporting pollination networks in tropical agroecosystems.

Abstract

Owa jawa merupakan primata endemik Pulau Jawa dengan status konservasi genting (endangered). Perilaku afiliatif merupakan perilaku sosial yang bersifat positif berupa bersentuhan, duduk berdekatan, saling menelisik, berpelukan, dan perilaku seksual. Penelitian ini bertujuan untuk mengidentifikasi perilaku afiliatif serta kecenderungan perilaku kawin yang dilakukan pasangan owa Jawa dewasa di Pusat Rehabilitasi Primata Jawa (PRPJ) Patuha, Ciwidey, Jawa Barat. Data perilaku afiliatif diambil dengan menggunakan metode focal-animal sampling selama 104 jam. Perilaku afiliatif yang teramati pada pasangan owa jawa Acoy (♀) – Iwan (♂) dan Kimba (♀) – Douglas (♂), yaitu mendekati, duduk berdekatan, bergelantungan berdekatan, dan saling menelisik. Perilaku duduk berdekatan paling banyak dilakukan oleh kedua pasangan, sedangkan perilaku saling menelisik hanya dilakukan oleh pasangan Kimba (♀) – Douglas (♂). Perilaku duduk berdekatan dilakukan dalam durasi yang paling tinggi dibandingkan perilaku afiliatif lainnya. Kedua pasangan tidak memiliki kecenderungan melakukan perilaku kawin selama pengamatan dilakukan.

Abstract

     Currently orangutans exist in increasingly fragmented and isolated populations. While Sumatran orangutan is primarily found in northern Sumatra, the Bornean is distributed in Central, West, and East Kalimantan, Sarawak and Sabah.  The determination of intra- and inter-species variation between Bornean and Sumatran orangutans has been stated to be essential for both the management of orangutan reintroduction projects and the planning of conservation strategies to preserve the remaining wild populations.  This study aimed to identify two species of Orangutans (Pongo sp.) by means of RFLP (Restriction Fragment Length Polymorphisms) analyses of mitochondrial DNA (mtDNA).  An approximately 540 bp single fragment of the ND5 gene near the 5’-region was PCR amplified for all samples tested.  Digestion pattern for both AluI and MseI were different between two groups of ND5 fragments in this study.  Present result showed a rapid protocol to identify these two species by means of RFLP (Restriction Fragment Length Polymorphism) analyses of mtDNA (mitochondrial DNA).  This technique can be applied easily to rehabilitation centres and zoos to resolve species discrimination problem.  Keywords: Orangutans, Pongo sp., Sumatra, Borneo, discrimination

Abstract

The serum realibility was tested in captive breeding conditions on the long-tailed macaques (Macaca fascicularis). Serum and buffy coat were applied to standard protocol of DNA extration following the amplification of microsatellite DNA locus of D2S1777 by PCR and visualized PCR products by means of PAGE with silver staining.  The amount of genomic DNA extracted from serum was sufficient for genotyping individuals at DNA microsatellite locus of D2S1777 with the allele size is approximately 160 bp.  We show that serum can provide a reliable alternative for obtaining DNA where taking blood using anticoagulant is impracticable

Abstract

Southern Cassowary (Casuarius casuarius) is  a seed disperser of North Australia and Southern Papua lowland forest ecosystem. Despite its dominant distribution in Southern Papua, there is a lack of information regarding its population and habitat characteristics. Due to its high sensitivity, the southern cassowary is rarely seen across the forest, yet the signs of its presence (feces and footprints) are abundant. This study analyzed the distributions, population, and habitat characteristics of the southern cassowary’s in Sota and Wanggo Resort, Wasur National Park, Southern Papua. Maximum Entropy results showed that its distribution focused on the northeastern area of Wanggo Resort and several points north of Sota Resort. Using fecal distance sampling, this study found that the southern cassowary population density in Wasur National Park areas was 0.8 ind/km2, primarily in lowland forests. The area corresponds to the variables that most influence the southern cassowary, which are NDVI, annual precipitation, and distance to the road. These findings underscore the urgency of local stakeholders to pay specific attention to lowland forests in Wasur National Park.
