Abstract. Purnama MF, Sirza LOMJ, Sari SF, Salwiyah, Haslianti, Abdullah, Suwarjoyowirayatno, Findra MN, Nurhikma, Agriansyah A, Hidayat H, Syukur, Anwar K. 2022. Diversity report of freshwater gastropods in Buton Island, Indonesia. Biodiversitas 23: 1938-1949. This study was located in Buton Island consisted of 5 administrative districts/cities (Baubau City, Buton District, South Buton District, Muna District and North Buton District) and was conducted for 1 year (August 2019-August 2020). The output is to reveal the potential richness of the biodiversity of freshwater gastropods as a first step to optimize the utilization of freshwater gastropod resources in the Buton Islands. Determination of sampling location for gastropods was carried out by purposive sampling method and the selection of gastropod samples using simple random sampling method at a predetermined location based on the presence of gastropods. Gastropod samples (epifauna/infauna) were collected manually without special fishing gear with gloves, paralone pipes (3.5 inches), and filter (1 mm). The gastropods found in Buton Island consist of 18 genera and 40 species. Freshwater gastropods spread over 8 families, namely Cyclophoridae, Planorbidae, Lymnaeidae and Thiaridae. Among the species, there are several invasive alien species (IAS) such as Tarebia granifera, Melanoides tuberculata and Achatina fulica. These three species always dominate the habitat space where they are found. Most gastropod communities in 5 districts/cities live in fast-flowing rivers with rock, gravel and sand substrates. Only a few of them are found in artificial inland waters such as rice fields, embankments, dams and drainage. This study became a first step to optimize the utilization of gastropod resources and sustainable management, especially related to the conservation of native species from the threat of IAS.

Abstract. Salwiyah, Purnama MF, Syukur. 2022. Ecological index of freshwater gastropods in Kolaka District, Southeast Sulawesi, Indonesia. Biodiversitas 23: 3031-3041. Kolaka District is one of the existing centers of high freshwater gastropod diversity in Southeast Sulawesi Province, Indonesia. more than 30 species of inland gastropods occupy this area and some of them (species) are used by local communities as food (daily consumption). This research was conducted for 4 months, namely January-April 2021 in Kolaka District, Southeast Sulawesi, Indonesia. The purpose of this study was to determine the ecological index (abundance, diversity, evenness, species richness, dominance, and distribution pattern) of the inland gastropod community in Kolaka. The sampling location of gastropods was determined qualitatively using the purposive sampling method and sampling using a simple random sampling technique (Quantitative based). Gastropod samples were collected manually (hand picking) using a paralone pipe (3.5 inches), Sieve (1 mm), and Gloves. The total gastropod sample obtained during the study was 1929 individuals consisting of 9 families, 19 genera, and 33 species. The average abundance of the gastropod population reached 96.45 ind./m2 and the abundance of gastropod species ranged from 0.75-15.05 ind./m2. Overall, the results of the gastropod ecological index analysis showed a stable condition, where the diversity of gastropod species was categorized as high (H': 3.20), moderate evenness (E: 0.90), and high species richness (R: 4.23), dominant dominance. showed that there were no dominant species (C: 0.1) and the distribution of gastropods showed a clumped pattern (Ip: 0.01). Empirically the ecological index data is a scientific justification related to the sustainability of inland water ecosystems or a description of the current freshwater homeostasis system in Kolaka.
