This paper shows that Bivalve assemblages could serve as excellent indicators of disturbance and ecosystem instability. The goal of this study was to compare two sets of data in order to determine the differences between two different periods belonging to Bivalve assemblage in the muddy detritic bottom of the northern Adriatic Sea in the post-anoxic period during December 1989, 1990, 1991 and quite a while later, during 2003, 2004 and 2005. Abundances of some indicator species such as Corbula gibba, Modiolarca subpicta, and Timoclea ovata were detected during the post-anoxic period. Recruitment in the quality of Bivalve assemblages was proved by the ecologic and biotic indexes during 2003, 2004 and 2005, during a period of relatively stable ecological conditions. Fluctuation in Bivalve diversity due to the ecological quality of the marine ecosystem in the eastern part of the northern Adriatic Sea is also discussed. Key words: hypoxia; Bivalve assemblages; indicator species; soft bottoms; northern Adriatic Sea Introduction Recent reviews and summaries have provided good introductions on how hypoxia and anoxia came to be such a large and serious problem in the aquatic ecosystem (Gray et al. -

For this purpose, the material collected from the area between the years 2005 and 2009, within the framework of different projects, was investigated. The investigation of the material taken from various biotopes ranging at depths between 0 and 100 m resulted in identification of 286 mollusc species and 27542 specimens belonging to them. Among the encountered species, Vitreolina cf. perminima (Jeffreys, 1883) is new record for the Turkish molluscan fauna and 18 species are being new records for the Turkish Levantine coast. A checklist of Iskenderun mollusc fauna is given based on the present study and the studies carried out beforehand, and a total of 424 moluscan species are known to be distributed in Iskenderun Bay.

Biodiversity and Spatial Distribution of Molluscs in Tangerang Coastal Waters, Indonesia 1,2Asep Sahidin, 3Yusli Wardiatno, 3Isdradjad Setyobudiandi
Biodiversity and spatial distribution of molluscs in Tangerang coastal waters, Indonesia 1,2Asep Sahidin, 3Yusli Wardiatno, 3Isdradjad Setyobudiandi 1 Laboratory of Aquatic Resources, Faculty of Fisheries and Marine Science, Universitas Padjadjaran, Bandung, Indonesia; 2 Department of Fisheries, Faculty of Fisheries and Marine Science, Universitas Padjadjaran, Bandung, Indonesia; 3 Department of Aquatic Resources Management, Faculty of Fisheries and Marine Science, IPB University, Bogor, Indonesia. Corresponding author: A. Sahidin, [email protected] Abstract. Tangerang coastal water is considered as a degraded marine ecosystem due to anthropogenic activities such as mangrove conversion, industrial and agriculture waste, and land reclamation. Those activities may affect the marine biodiversity including molluscs which have ecological role as decomposer in bottom waters. The purpose of this study was to describe the biodiversity and distribution of molluscs in coastal waters of Tangerang, Banten Province- Indonesia. Samples were taken from 52 stations from April to August 2014. Sample identification was conducted following the website of World Register of Marine Species and their distribution was analyzed by Canonical Correspondence Analysis (CCA) to elucidate the significant environmental factors affecting the distribution. The research showed 2194 individual of molluscs found divided into 15 species of bivalves and 8 species of gastropods. In terms of number, Lembulus bicuspidatus (Gould, 1845) showed the highest abundance with density of 1100-1517 indv m-2, probably due to its ability to live in extreme conditions such as DO < 0.5 mg L-1. The turbidity and sediment texture seemed to be key parameters in spatial distribution of molluscs. Key Words: bivalve, ecosystem, gastropod, sediment, turbidity. Introduction. Coastal waters are a habitat for various aquatic organisms including macroinvertebrates such as molluscs, crustaceans, polychaeta, olygochaeta and echinodermata. -

HARTLEY (http://zoobank.org/urn:lsid:zoobank.org:author:5C51172A-E84D-426C-918B-8DE2EAD48986) Hartley Anderson Limited, Blackstone, Dudwick, Ellon, Aberdeenshire AB41 8ER, UK ([email protected]) Abstract Hartley, J.P. 2014. A review of the occurrence and ecology of dense populations of Ditrupa arietina (Polychaeta: Serpulidae). Memoirs of Museum Victoria 71: 85–95. Dense populations of the free-living serpulid Ditrupa arietina were first recorded to the west and north of the Shetland Isles in the 1920s and have since been reported from the Celtic and North Seas, the Armorican shelf, the Mediterranean and the Azores. These dense populations (of many thousands per square metre) numerically dominate the benthic fauna, and the tubes provide sites of attachment for a range of other species. Vacated tubes are also occupied by other animals, and tube fragments can contribute significantly to biogenic carbonate sediments, both Recent and fossil. Dense Ditrupa populations have been the subject of detailed autecological research over the last 15 years, but in spite of the apparent ecological importance of the species, it is not reflected in the European Nature Information System (EUNIS) or other North-east (NE) Atlantic habitat classifications. This paper provides a synthesis of the environmental conditions where high densities of Ditrupa have been found, with new data from seabed samples and photos. -

An Illustrated Key for the Western European Solenidae and Pharidae
127 Gloria Maris 46 (6) 127-141 Antwerpen, maart 2008 An illustrated key for the western European Solenidae and Pharidae Nathal SEVERIJNS Buizegemlei 111, B-2650 Edegem, Belgium n. severij [email protected] The identification of the different species of the Pharidae and Solenidae is often not easy. This is especially true for the five species of the genus Ensis. Previously, two tables with a key for identification and extensive descriptions of the western European Pharidae and Solenidae were already published (van Urk, I 964a, l 964b; Moerdijk, 2000). Recently, the species of the genus Ensis in Europe were compared to each other in a paper reviewing the occurrence and spreading of Ensis directus in Europe (Severijns, 2002). To complement these works a key is presented here for the identification of the different species which uses only a minimum oftruly characteristic features, complemented with figures that show these key features as well as pictures ofreal specimens of the different species. The intemal features such as adductor scars, the pallia) scar and pallial sinus are indicated by black outlines on pictures of real specimens. The species that are treated here are listed on the next page. Dutch summary: De determinatie van de verschillende in West-Europa voorkomende soorten zwaard scheden (Pharidae) en mesheften (Solenidae) is niet eenvoudig. Dit is vooral het geval voor de niet minder dan vijf verschillende soorten van het geslacht Ens is. Vroeger werden voor de soorten die in West-Europa voorkomen reeds uitvoerige beschrijvingen gepubliceerd in de vorm van twee tabellen met determineersleutel (van Urk, l 964a, l 964b; Moerdijk, 2000).
