Abstract. Salis VM, Tjong DH, Syaifullah, Dahelmi, Aadrean, Roesma DI. 2025. Morphology and molecular studies to reveal the taxonomic status of endemic fish Barbonymus belinka of Lake Singkarak, West Sumatra, Indonesia. Biodiversitas 26: 536-550. Species identification is very important in taxonomy and conservation. There are some cases where the distinctive morphological characters of a species show minor differences; for example, the Balingka fish (Barbonymus belinka), endemic to Lake Singkarak, West Sumatra, Indonesia and the Kapiek fish (Barbonymus schwanefeldii). The local community around Lake Singkarak gives two names to the Balingka fish based on size (the larger ones are called Balingka, and the smaller ones are called Kapiek), it can affect the taxonomy and validity of biodiversity data. The lack of comprehensive information on B. belinka has led to the species being classified as Data Deficient (DD) on the IUCN Red List. Additionally, the presence of a DNA barcode for Balingka fish in the BOLD system, listed under a different species name than in GenBank (NCBI), raises concerns about potential species misidentification and data inconsistencies. A thorough taxonomy review of Balingka fish (B. belinka) is necessary, utilizing both morphological and molecular approaches. This study aims to clarify the taxonomy and investigate the phylogenetic relationships of the two fish species through morphological and molecular analyses, utilizing Cytochrome Oxidase-I and Cytochrome b gene sequences. Individual samples were used for morphological identification, while liver tissue was used for molecular analysis. The results showed morphometric variations, but meristic traits confirmed that both fishes belong to the same species, B. schwanefeldii. Molecular analysis shows a genetic distance of 0-1.4% for Cytochrome Oxidase-I gene and 0-2.3% for Cytochrome b gene, indicating the same species. Two specific bases at 585 bp of the Cytochrome Oxidase-I gene and four specific bases at 599 bp of the Cytochrome b gene are also found unique to B. schwanefeldii from Lake Singkarak, suggesting that these two fishes may represent the same species.

Abstract. Syamsi F, Novarino W, Dahelmi, Chairul. 2025. The study of diversity and distribution of bats in several fragmented forests and small adjacent islands in Batam City, Riau Island, Indonesia. Biodiversitas 26: 223-232. Bats are ecologically and taxonomically diverse and crucial in tropical ecosystems, including on islands. This study compares bat diversity in fragmented forests on urban islands and adjacent islands connected by bridges to assess the impact of urbanization on bat populations, providing insights for conservation and habitat management. We sampled bats across four sites in Batam City, Indonesia, including two secondary forests (SF1 and SF2) and two small islands (SI1 and SI2). Using 120 harp trap nights and 120 net nights, we captured 429 bats representing 15 species and 4 families. Our findings revealed moderate bat diversity (H' 1.02 to 1.66), with SF1 being the most stable habitat, showing balanced species richness, evenness (0.72), and low dominance (0.24), indicating an evenly distributed community. The Bray-Curtis Similarity index indicated that SF1 had a distinct bat community with only 58% similarity to other habitats. Notably, two near-threatened species were found in SF1, emphasizing its ecological significance. The study suggests that fragmented forests with healthy vegetation and habitat complexity surrounding urban areas are more supportive of bat populations than small islands with limited resources. These results highlight the need for targeted conservation efforts in forest fragments surrounding urban areas to preserve bat diversity in Batam City, Riau Island, Indonesia.
