Abstract. Nasution A, Perwitasari-Farajallah D, Utami-Atmoko SS. 2020. The distribution and density of Tapanuli orangutans (Pongo tapanuliensis) at potential corridor locations between forest fragments in Batang Toru, North Sumatra, Indonesia. Biodiversitas 21: 5382-5388. The newly discovered Tapanuli orangutan (Pongo tapanuliensis) is in danger of being lost in a few decades due to their small population number in fragmented forest of Batang Toru. The major threats faced by this critically endangered ape, including: hunting, habitat loss, and fragmentation due to large infrastructure development and other developments in the key corridor area. The establishment of corridor and buffer zone is one such effort to maintain their population and bring them from the brink of extinction. Data on the population and distribution are needed to assess and provide baseline information for investigating the habitat condition of potential corridors and buffer zones. This study aimed to analyze population and distribution of Tapanui orangutan (Pongo tapanuliensis) in buffer zone and potential corridor of Batang Toru. Our study provides an initial dataset prior to the development of the hydrodam, which is important to understand the future post-development impact. The study was carried out in disturbed (Hutaimbaru and Bulu Mario) and undisturbed forest (Sitandiang and Hopong) of Batang Toru from June 2015 until February 2016. Orangutan nest, fig (Ficus spp.), and trees bearing fruit were recorded using a line transect method. This research showed that population and distribution of orangutan were influenced by forest conditions, threat level, and fruit availability. There were fewer nests per km2 in disturbed forest than in undisturbed forest, resulting in an orangutan density estimation to be 0.24 ind/km2, 0.14 ind/ km2 (Hutaimbaru and Bulu Mario) and 0.74 ind/km2, 0.36 ind/km2 (Sitandiang and Hopong). Number of nest in transects was influenced by the availability of fig class I and class II, but not fruit tree. The APL forest of Sitandiang is key area to connect the three populations of Tapanuli orangutan: east Batang Toru, west Batang Toru, and Sibualbuali. Furthermore, orangutan’s nests were encountered both in protected and non-protected forest, thus protection of such areas, especially areas including primary forest that harbor orangutan is essential for their long term survival. The conservation measures and action Tapanuli orangutan is alarming, thus we recommend all remaining habitat should be officially and strictly protected and collaboration work with multi-stakeholder is essential to establish the corridor as well as the strategic management plan of Tapanuli orangutan.

Abstract. Qomariyah IN, Perwitasari-Farajallah D, Iskandar E, Berthier JM. 2023. Characteristics of sleeping sites and sleeping trees selected by Celebes crested macaques (Macaca nigra) in Tangkoko, North Sulawesi, Indonesia. Biodiversitas 24: 6200-6208. Research on the selection of sleeping sites is imperative in providing information on the fitness and survival of a species. We investigated the characteristics of the sleeping sites and the sleeping trees selected by wild Celebes crested macaques (Macaca nigra Desmarest 1822) in North Sulawesi, Indonesia, as well as their spatial and temporal use. The study was conducted in two groups of macaques for nine months (187 study days) from September 2020 to June 2021. These macaques avoided using the same sleeping site on consecutive nights. Two predator encounters (Python reticulatus Schneider 1801) were recorded near the sleeping sites, but pythons caught no monkeys during the study period. The macaques used 58 trees from 13 species as sleeping trees, of which 79% of the sleeping trees were also food trees. M. nigra chose sleeping trees with higher diameter, height, and a bigger Important Value Index than the surroundings. The average distance between sleeping trees and feeding trees in the morning and evening were 203 m and 127 m, respectively. These results suggest that optimal foraging strategy and predator avoidance are important factors in selecting sleeping sites, providing a broader understanding of the habitat preferences of the Critically Endangered M. nigra.

Abstract. Miharja J, Atmowidi T, Priawandiputra W, Perwitasari D, Kahono S. 2024. Species richness and nest entrance characteristics of stingless bees (Hymenoptera: Apidae: Meliponini) in Ujung Kulon National Park, Banten, Indonesia. Biodiversitas 25: 4961-4970. Stingless bees (Hymenoptera, Apidae, Meliponinae) are distributed in tropical and subtropical regions. Ujung Kulon National Park (UKNP), a conservation area of flora and fauna in the western part of Java, was designated by UNESCO in 1992 as a Natural World Heritage site. This study measured the species richness, nesting site, and nest-entrance characteristics of stingless bees in UKNP. Samplings of stingless bees were conducted by road sampling and based on the information from officers of UKNP and the local communities from June to December 2023. Results showed that 163 colonies of stingless bees were found belonging to four species, i,e., Tetragonula laeviceps, Tetragonula fuscobalteata, Heterotrigona itama, and Lepidotrigona terminata. Based on the number of colonies, L. terminata was the most dominant (44%), followed by T. laeviceps (41%), T. fuscobalteata (12%), and H. itama (3%), respectively. The nest of T. laeviceps was found in residential house cavities, bamboo and tree holes, and old and abandoned ant nests, showcasing their adaptability and resourcefulness. Meanwhile, the nest of T. fuscobalteata was found in the rock holes and tree cavities; L. terminata and H. itama nests were found in tree cavities. The unique nest entrance characteristics of each species further highlight their fascinating adaptability. This study showed a new distribution record of stingless bees in Ujung Kulon National Park, Banten, Indonesia.

Abstract

Fish diversity is widely used as an indicator of freshwater ecosystem stability and environmental quality, particularly in semi-urban areas experiencing increasing anthropogenic pressure. This study assessed fish diversity in three artificial lakes on the IPB University Dramaga Campus: Lake LSI, Lake SDGs, and Telaga Inspirasi. Sampling was conducted in April 2025 using a combination of active and passive capture methods. Collected specimens were identified to species level, and diversity was evaluated using the Shannon, Simpson, and evenness indices. A total of 12 fish species from nine families were recorded. Five species were introduced, with Oreochromis niloticus and Poecilia reticulata identified as the dominant taxa. Telaga Inspirasi exhibited the highest Shannon index (1.390) and the lowest Simpson value (0.733), indicating relatively high diversity and low dominance. Lake LSI supported the greatest species richness (10 species) but showed relatively high dominance (Simpson index = 0.581). Lake SDGs displayed the highest evenness value (0.610), reflecting a more balanced distribution of individuals. Environmental parameters at all sites remained within suitable ranges for fish survival. These findings highlight differences in fish community structure among lakes and emphasise the importance of ecological monitoring for freshwater biodiversity management.
