“…Some of the crabs and gastropods were taken for identification. The obtained benthic samples (gastropods and crabs) were preserved with 70% alcohol solution in labeled plastic containers for further analysis (Hastuti et al 2018;Rahman et al 2021). Samples were observed using a stereo microscope with a magnification of 40-100x and identified using a guide from books (Dharma 2005;Murniati and Pratiwi 2015;Bowling 2019).…”

Abstract. Retnaningdyah C, Febriansyah SC, Hakim L. 2022. Evaluation of the quality of mangrove ecosystems using macrozoobenthos as bioindicators in the Southern Coast of East Java, Indonesia. Biodiversitas 23: 6480-6491. The mangrove ecosystem in East Java has been degraded due to land use change. Some of these mangrove ecosystems have been restored. However, the success of these restoration activities has never been evaluated. This study aimed to evaluate the quality of some mangrove ecosystems on the Southern Coast of East Java by observing the physical and chemical quality of water and macrozoobenthos that live in mangroves, especially crustaceans and gastropods, as bioindicators. Samplings were carried out on seven mangrove ecosystems, namely restored ecosystems (Cengkrong, Sine, Getem, Kondang Merak, Clungup Mangrove Conservation/CMC) and natural ecosystems as reference sites (Alas Purwo National Park/TNAP and Sempu island). The water quality parameters observed were pH, conductivity, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), nitrate, orthophosphate, Total Suspended Solid (TSS), salinity, sulfide content (H2S), oil and fat content, and dissolved lead (Pb) content. The macrozoobenthos communities observed were gastropods and crabs, while the mangrove communities monitored were only trees, using plots, each measuring 10x10 m. The results showed that some water quality parameters did not meet the sea water quality standards for marine life, namely DO and nitrate levels for all locations, H2S, and oil/fat in some locations. The quality of the restored mangrove ecosystem in the Cengkrong and CMC areas was better than that of other sites, with a Shannon-Wiener species diversity index (H') for mangrove trees of 2.796 and 2.235 and was close to the quality at the reference sites, namely Alas Purwo and Sempu island (H' 2.953 and 2.356). The H' value of macrozoobenthos in the Cengkrong and CMC mangrove ecosystem was also high (4.37 and 3.47) and almost the same as the H' value of Sempu Island and Alas Purwo (3.45 and 3.88), while in other mangrove ecosystems it ranged from 1.33 to 2.60. The species diversity of mangrove vegetation had a significant (? 0.05-0.1) to very significant (? <0.05) positive correlation with the diversity of crabs and gastropods, so the diversity of macrozoobenthos (crabs and gastropods) can be used as a bioindicator of the quality of the mangrove ecosystem.

“…Various types of environments in the coastal area of Liki Island provide suitable conditions and habitat types for many species of gastropods. Gastropod habitats are generally in the littoral zone, including tidal areas (Nurhayati et al 2021), where they can attach to seagrass and mangroves' roots, stems, and leaves (Rahman et al 2021). Most gastropods are also immersed in sandy mud substrates (Dharma 1988;Bula et al 2017;Saleky et al 2019).…”

Abstract. Sujarta P, Mailissa MG, Keiluhu HJ, Hadisusanto S, Yuliana S. 2022. Community distribution and utilization of gastropods in the Coastal Area of Liki Island, Sarmi District, Papua, Indonesia. Biodiversitas 23: 5001-5011. Gastropods and snails are mollusk phylum animals with diverse species that inhabit and spread in various marine ecosystems. The main objective of this study was to determine the structure of gastropod communities and their utilization in the coastal area of Liki Island, Sarmi District, Papua, Indonesia. Samples of gastropods were collected through descriptive-quantitative surveys using the line-transects technique. In addition, information on the utilization of gastropods was collected from surveys with semi-structural interviews with selected respondents from Liki Island, the outermost island in East Indonesia, with a total area of 1318.54 ha. The result showed a total of 1812 living specimens from 63 species of gastropods from 23 families, collected from six sampling stations, with 182-603 specimens on average. There were five species of gastropods encountered in all sampling stations, namely Conus litteratus (family of Conidae), Monetaria moneta, Monetaria annulus (Cypraeidae), Oxymeris crenulata (Terebridae), and Polinices flemingianus (Naticidae). The highest Importance Value Index (IVI) belonged to Nerita albicilla (Neritidae) from Station 1 (IVI 58.45). In contrast, the lowest belonged to the species of Nassarius limnaeiformis (Nassariidae), Oliva caerulea, and Oliva oliva (Olividae) from Station 4 (each IVI 2.56), with the moderate value of Shannon-Wiener Diversity Index and low value of Dominance Index. People in the coastal area of Liki Island use 12 species of gastropod as wall ornaments and consume 12 species of gastropod, as well. In general, the people of Liki Island use gastropods wisely based on the socio-cultural characteristics of the local community.

“…High gastropod species richness is related to primary productivity rates as most gastropods are herbivorous, although some are predatory (Pribadi et al 2009). Thus, niche diversification drives a high species richness community (Béguinot 2021;Rahman et al 2021). Gastropods are ecosystem engineers and keystone species; losing certain species may cause ecological phase shifts.…”

Abstract. Isroni W, Sari PDW, Sari LA, Daniel K, South J, Islamy RA, Wirabuana PYAP, Hasan V. 2023. Checklist of mangrove snails (Gastropoda: Mollusca) on the coast of Lamongan District, East Java, Indonesia. Biodiversitas 24: 1676-1685. Mangroves are crucial transition zone ecosystems providing sheltered nursery zones and abundant marine and terrestrial biota resources. Mangrove snails (Gastropoda: Mollusca) are ecologically important ecosystem engineers, trophic links for higher predators, and a source of human food and livelihoods. Mangrove snails are also ideal bioindicators to monitor environmental pollution. A strong baseline understanding of current richness and distribution is therefore important. Thus, this study provides data on the species composition of mangrove snails on the north coast of Lamongan District, East Java, Indonesia. Sampling was conducted during low tide at four stations from September to November 2022 using square transects. Ten families consisted of Cerithiidae, Cypraeidae, Fasciolariidae, Muricidae, Naticadae, Neritidae, Plaxidae, Potamididae, Trochidae, and Turbinidae comprising 20 genera and 24 species. The most dominant family found is Muricidae, with six genera and eight species. Most mangrove snails were found in rocky, sandy substrates, around trees, and mangrove roots. Gastropods observed in this study were alive and dead (i.e., empty shells). We suspect that there is still much-hidden diversity of Gastropoda in this region. Therefore, we suggest that future work addresses differences in microhabitat and snail morphology with quantitative and semi-quantitative methods to understand distribution drivers and ecological roles better.
