Medan, Agustus 2020 UNIVERSITAS SUMATERA UTARA ABSTRAK HERDIANA RUKMANA. Hubungan Karakteristik Habitat Terhadap Kepadatan Siput Bulan (Natica tigrina) di Perairan Tanjung Tiram Kabupaten Batu Bara Provinsi Sumatera Utara. Dibimbing oleh IPANNA ENGGAR SUSETYA. Siput Bulan (Natica tigrina) termasuk ke dalam salah satu jenis biota Gastropoda yang banyak dijumpai di Perairan Tanjung Tiram Kabupaten Batu Bara. Sejauh ini data mengenai kepadatan, distribusi dan analisis Komponen Utama di Perairan Tanjung Tiram Kabupaten Batu Bara belum pernah ditemukan sehingga perlu dilakukan penelitian. Penelitian ini bertujuan untuk mengetahui kepadatan dan hubungan karakteristik habitat Siput Bulan terhadap kepadatan Siput Bulan. Pengambilan sampel Siput Bulan dilakukan pada bulan Juni–Juli 2019 di Perairan Tanjung Tiram pada 3 stasiun yang berbeda. Siput Bulan yang diperoleh di setiap stasiun dihitung jumlah individunya, selanjutnya dilakukan analisis yang meliputi Kepadatan, distribusi dan Analisis Komponen Utama. Pengukuran parameter fisika-kimia perairan dilakukan secara insitu dan exsitu. Hasil penelitian menunjukkan bahwa kepadatan Siput Bulan paling banyak pada stasiun II dengan nilai 213ind/m2. Distribusi yang di peroleh pada setiap stasiun di Perairan Tanjung Tiram bersifat berkelompok yaiutu Id> 1 pola sebaran berkelompok, serta hubungan Principal Component Analysis (PCA) antara kepadatan Siput Bulan terhadap DO, kedalaman, kecerahan, c-organik, nitrogen total dan fosfat tergolong berkorelasi positif.

Relationship of Habitat Characteristics to the density of the Moon Snail ( Natica tigrina ) in Tanjung Tiram Waters, Batu Bara Regency, North Sumatra Province. Supervised by IPANNA ENGGAR SUSETYA . The Moon Snail ( Natica tigrina ) is one of the Gastropod biota types often found in the waters of Tanjung Tiram, Batu Bara Regency. So far the data on the density, distribution and analysis of the Main Components in the Tanjung Tiram Waters of Batu Bara Regency have never been found so research needs to be done. This study aims to determine the density and relationship characteristics of the Moon Snail habitat to the density of the Moon Snail . Samples of the Moon Snail were conducted in June-July 2019 in Tanjung Tiram waters at 3 different stations. Moon snails obtained at each station are counted individually , then performed an analysis which includes Density , Distribution and Analysis of Main Components . The measurement of the physico-chemical parameters of the waters is done in situ and exsitu . The results showed that the density of the Moon Snails was most at Station II with a value of 213 ind / m 2 . The distribution obtained at each station in Tanjung Tiram waters is in groups of Id> 1 group distribution pattern , as well as the Principal Component Analysis (PCA) relationship between Moon Snail density to DO, depth, brightness, c-organic, total nitrogen and phosphate classified as correlated positive. While the relationship between the density of the Moon Snail against temperature, salinity and pH is negatively correlated.

    BIOTROPIA Vol. 17 No. 2, 2010: 62 - 76 THE STATUS OF MOLLUSK DIVERSITY AND PHYSICAL SETTING OF THE MANGROVE ZONES IN CATANDUANES ISLAND, LUZON, PHILIPPINES JIMMY T. MASAGCA1,2 ANGELICA V. MENDOZA² and ESTRELLA T. TRIBIANA² ¹Pacific Island Institute for Pedagogy, Technology, Arts & Sciences, Inc. De La Salle University-Dasmarinas,~ Philippines ²Catanduanes State Colleges, Calatagan, Virac 4800, Catanduanes, Philippines Received 06 August 2010 / Accepted 13 September 2010 ABSTRACT The status of mollusk diversity and physical setting of mangrove areas in Catanduanes island, Luzon (Philippines) are described. A total of 57 species of mollusks, consisting of 27 gastropods and 30 bivalves were recorded in the island. Registering higher values of species diversity indices (Margalef) and species richness (Menhinick) are the prosobranch, Terebralia sulcata; corbiculid bivalve, Geloina coaxans; potamidiids, Cerithidea cingulata and Cerithidea rhizophorarum; and two other species of the genus Littorina (Littorinopsis). Using the physiographic model, majority of the mangrove areas under study follow the composite river and wave-dominated setting with some few areas having the wave-dominated, tide-dominated allochthonous setting. Keywords: Mollusk diversity, mangrove areas, Philippines INTRODUCTION In recent years, there had been an increased interest on the status of mangrove areas in tropical coastal ecosystems for economic and ecologic reasons (McNeely et al. 1990, Maler 1997, Masagca 2006). These are the most biologically diverse of all marine ecosystems but are being degraded worldwide by human activities potentially leading to numerous extinctions (Rios-Jara 2009). Conservation efforts targeted toward these ecosystems could help in averting the loss of tropical biodiversity. The first step according to Hamilton and Snedaker (1984) towards the attainment of the goals of conservation and sustainable use of the mangrove ecosystem is to develop data base.

Present address: The Kyoto University Museum, Yoshida Honmachi, Sakyo-ku, Kyoto 606-8501, Japan (email: [email protected]) Received December 19, 2005; Revised manuscript accepted May 26, 2006 Abstract. Cerithiform gastropods possess high-spired shells with small apertures, anterior canals or si- nuses, and usually one or more spiral rows of tubercles, spines or nodes. This shell morphology occurs mostly within the superfamily Cerithioidea. Several morphologic characters of cerithiform shells are adap- tive within five broad functional areas: (1) defence from shell-peeling predators (external sculpture, pre- adult internal barriers, preadult varices, adult aperture) (2) burrowing and infaunal life (burrowing sculp- tures, bent and elongated inhalant adult siphon, plough-like adult outer lip, flattened dorsal region of last whorl), (3) clamping of the aperture onto a solid substrate (broad tangential adult aperture), (4) stabilisa- tion of the shell when epifaunal (broad adult outer lip and at least three types of swellings located on the left ventrolateral side of the last whorl in the adult stage), and (5) righting after accidental overturning (pro- jecting dorsal tubercles or varix on the last or penultimate whorl, in one instance accompanied by hollow ventral tubercles that are removed by abrasion against the substrate in the adult stage). Most of these char- acters are made feasible by determinate growth and a countdown ontogenetic programme.

Tel./Fax. +0435-821752 e-mail: [email protected] ABSTRACT The aim of the current study is to calculate the value of the abundance, diversity, and the density of phyla mollusks in the Tutuwoto mangrove area of Anggrek District. The survey method is used in this study as a method, which means that it collects the data directly at the research area. The observations were carried out under mangrove stands. The area of the observation plot is 5m x 5m. Phylum mollusks collected at the study site were counted by the number of individuals, abundance, diversity, and density of the types of each species. Sanon-Wienner formula is used to calculate the species diversity, Brower formula is used to calculate the density, and Odum formula is used to calculate the abundance of the species. The findings show that it is found that the reasearch about phylum mollusks in Tutuwoto mangrove area consisted of 6 (six) types namely Terebralia sulcata, Terebralia palustris, Nerita articulate, Hexaplex trunculus, Anadara granosa, and Mactra grandis. Based on the calculation of the abundance, diversity, and density of the mollusks phylum at the research site, there are several types that have the highest value.

  • A Key to the Potamidid Snails (Longbums, Mudcreepers and Treecreepers) of Northern Australia
    Northern Territory Naturalist (2013) 24: 68–80 Species Profile A key to the potamidid snails (longbums, mudcreepers and treecreepers) of northern Australia Richard C. Willan Museum and Art Gallery of the Northern Territory, GPO Box 4646, Darwin, NT 0801, Australia. Email: [email protected] Abstract Longbums and the smaller mudcreepers and treecreepers (Mollusca: Gastropoda: Cerithioidea: Potamididae) are amphibious surface-dwellers of tidal wetlands intimately associated with mangrove forests, depending on the trees for shelter from heat and desiccation, as a substrate, for food, and for protection from predators. A dichotomous key is presented to identify the eight species of Potamididae that occur in tropical northern Australia, several of which have similar looking shells. These species represent 27.6% of the global biodiversity for the family. This contribution describes the most useful features for distinguishing between species, and provides comments on habitat, ecological niche and geographical range of each species, with notes on exploitation by Aborigines. One species of true creeper, Cerithium coralium (Cerithioidea: Cerithiidae), is also included because it lives with, and may be easily confused with, juvenile longbums and/or the smaller potamidid species. Introduction Since I came to the Northern Territory in 1992, I have fielded more questions about longbums than any other group of molluscs. This might seem strange because they have little commercial significance (though once I saw frozen Telescopium telescopium for sale at Casuarina Square Shopping Centre) and their shells lack intrinsic beauty. However, they have huge ecological importance in mangrove forests and in the diets of coastal Aboriginal peoples. I quickly found the taxonomy, anatomy, behaviour and habitats of longbums and other members of the family Potamididae were a source of great interest to a lot of people.

Corresponding author: M. A. Sarong, [email protected] Abstract. The objective of the present study was to evaluate the diversity of gastropods in mangrove ecosystems of the western coast of Aceh Besar District, Indonesia. The sampling was done during March to April 2014 at four sampling locations and covered four villages namely Alue Naga, Kajhu, Neuheun and Ujung Batee. Three transects were determined at every sampling location and each transect had three plots (1 m x 1 m) and the gastropods were collected at the plots randomly by filtering the sediment using two level sieve. The study showed that Terebralia sulcata was the predominant species and this species was found at all of sampling locations. The Shannon-Wiener diversity index of gastropods was ranged between of 1.549 to 2.036, with an average value of 1.834. It was concluded that the diversity index of gastropods in western coast of Aceh Besar District was at low category. Key Words: mollusk, Terebralia sulcata, sediment, Rhizophora, frequency of incidence. Introduction. Approximately 15,652 ha of mangrove forest are located in Aceh Besar district, Indonesia (DKP Aceh Besar 2011).
