Abstract

Abstract. Islamy RA, Hasan V. 2020. Checklist of mangrove snails (Mollusca: Gastropoda) in South Coast of Pamekasan, Madura Island, East Java, Indonesia. Biodiversitas 21: 3127-3134. Mangrove forests are crucial to gastropods providing breeding and nursery grounds, food sources, and shelter from predators. They are useful bioindicators of environmental pollution. Consequently, it is crucial to understand the species richness of gastropods mangrove environments. This study aims to provide information about the species composition of mangrove snails in the South Coast of Pamekasan (Madura Island), East Java, Indonesia. Samplings were performed at low tide from 4 stations in December 2019 using a transect (10m x 10m). All samples were identified using reference books and published journal. We found a total of 10 family consist of Assimineidae, Cerithiidae, Ellobiidae, Littorinidae, Muricidae, Neritidae, Olividae, Planaxidae, Potamididae, and Trochidae with consist of 15 Genus, i.e., Assiminea, Clypeomorus, Cerithium, Rhinoclavis, Laemodonta, Littorarina, Tenguella, Semiricinula, Nerita, Clithon, Oliva, Planaxis, Pirenella, Telescopium, and Monodonta. The most common substrate where mangrove snails were found was rocks, sandy, and around the tree and roots of mangrove. All gastropods in this study found alive during our surveys and predominantly mangrove associated. We assume that there are still many snails that have not been surveyed at the location. We suggest to the future researcher to survey through different sampling efforts and sampling methods such as quantitative or semi-quantitative methods.

Short Communication: Presence of the vulnerable freshwater goby Sicyopus auxilimentus (Gobiidae, Sicydiinae) on Sangihe Island, Indonesia

“…Estuarine, freshwaters, and bays have been considered important habitats for different life cycle stages of Sicydiinae. These areas often have high productivity, serving as a potential spawning ground and migration route (Taillebois et al 2012;Iida et al 2015;Cloern 2018;Islamy and Hasan 2020). Adult Sicydiinae goby can be found in tropical freshwaters in the Indo-Pacific, where they greatly contribute to the diversity of the freshwater fish communities (Lord et al 2010;Teichert et al 2013;Ellien et al 2014).…”

Biodiversity and community assemblages of freshwater and marine macrozoobenthos in Gorontalo Waters, Indonesia

“…The presence of certain types of taxa is thought to be closely related to the flexibility of each species to the surrounding environments (Gosling 2008;Miltner and McLaughlin 2019). Gastropods are one of the most common groups of mollusks found in various substrates due to their high malleability compared to other classes on rigid and smooth substrates (Turra and Denadai 2006;Baharuddin et al 2018;Islamy and Hasan 2020). Wildan et al 2021 report that Gastropod becomes the most abundant taxa in Batang Toru River because of its wide adaptability and tolerance to environmental conditions.…”

Catatan Biodiversitas Gastropoda pada Ekosistem Mangrove Desa Kramat Kecamatan Mananggu Kabupaten Boalemo, Provinsi Gorontalo

“…Untuk kebutuhan dokumentasi dan identifikasi tiap spesies, representasi sampel dibuatkan spesimen, dikoleksi ke dalam kantung sampel, diawetkan menggunakan larutan alkohol 70%, dan diberi label. Identifikasi gastropoda berdasarkan morfologi dan cangkang merujuk pada FAO Volume 1 (1998), Abbott & Dance (1982), Tapilatu & Pelasula (2012), dan Islamy & Hasan (2020). Adapun identifikasi mangrove mengacu pada Noor et al (1999); Kasim et al (2018Kasim et al ( , 2019.…”

“…Di beberapa kawasan Indonesia, misalnya pesisir Suramadu, Kecamatan Bulak, Surabaya-Indonesia, Laily et al (2022) mencatat sebanyak 12 spesies gastropoda mangrove. Adapun, kekayaan spesies gastropoda mangrove tertinggi di Indonesia dilaporkan oleh Islamy & Hasan (2020), yang menemukan 16 genera anggota dari 10 famili gastropoda mangrove di pesisir Selatan Pulau Madura, Jawa Timur.…”
