Benthos Supported by the Tunnel-Valleys of the Southern North Sea
Benthos supported by the tunnel-valleys of the southern North Sea Bryony Pearce1*, David, R.Tappin2, Dayton Dove3 & Jennifer Pinnion1 1. Marine Ecological Surveys Limited, 3 Palace Yard Mews, Bath BA1 2NH 2. British Geological Survey, Keyworth, Nottingham 3. British Geological Survey, Edinburgh * Corresponding Author; Email: [email protected], Telephone: +44(0) 1225 442211, Fax: +44 (0) 1225 444411 Abstract The tunnel-valleys of the southern North Sea are arcuate sub-linear seabed depressions. The origin of these features has been the subject of much discussion, but they are generally considered to have been formed by subglacial erosion and sediment backfill beneath the outer margins of a receding ice sheet. We present here a study of two southern North Sea tunnel-valleys, the Silver and Sole Pits. Extensive areas of Sabellaria spinulosa reefs have been identified on the western flanks of the Silver Pit which extend down to the valley floor. It is likely that this reef complex would qualify as an Annex I habitat. The seabed of the Sole Pit is characterised by much sandier deposits than that of the Silver Pit, and supports an abundant bivalve community, dominated by Abra alba. This bivalve assemblage also contained Coarcuta obliquata which has only been recorded once before in the UK. Key Words Tunnel Valley, Benthos, Habitat, Seabed Mapping, Sabellaria spinulosa, Annex I Habitat, North Sea, Mulitbeam Introduction Tunnel-valleys are prominent features of the southern North Sea, where they form arcuate sub-linear seabed depressions with a limited sediment infill (Fig. 1). In the outer Humber area the valleys attain water depths up to 100 m and radiate outward from the mapped palaeo-ice margin of the Devensian (Weischelian) glaciations. -
Response to Oxygen Deficiency (Depletion): Bivalve Assemblages As an Indicator of Ecosystem Instability in the Northern Adriatic Sea

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. -

Diversity of Echinostomes (Digenea: Echinostomatidae) in Their Snail Hosts at High Latitudes

Echinostome trematode parasites have complex, multiple-host life-cycles, often involving migratory bird definitive hosts, thus leading to widespread distributions. Here, we examined the echinostome diversity in freshwater ecosystems at high latitude locations in Iceland, Finland, Ireland and Alaska (USA). We report 14 echinostome species identified morphologically and molecularly from analyses of nad1 and 28S rDNA sequence data. We found echinostomes parasitising snails of 11 species from the families Lymnaeidae, Planorbidae, Physidae and Valvatidae. -
Silicified Eocene Molluscs from the Lower Murchison District, Southern Carnarvon Basin, Western Australia

Abstract - Silicified Middle to Late Eocene shallow water sandstones outcropping in the Lower Murchison District near Kalbarri township contain a silicified fossil fauna including foraminifera, sponges, bryozoans, solitary corals, brachiopods, echinoids and molluscs. The known molluscan fauna consists of 51 species, comprising 2 cephalopods, 14 bivalves, 1 scaphopod and 34 gastropods. Of these taxa three are newly described, Cerithium lvilya, Zeacolpus bartol1i, and Lyria lamellatoplicata. 25 of these molluscs are identical to or closely comparable with taxa from the southern Australian Eocene. The occurrence of this fauna extends the Southeast Australian Province during the Eocene from southwest Western Australia along the west coast north to at least 27° present day south latitude; consequently the province is here renamed the Southern Australian Province. Keywords: siliceous fossils, Eocene, Kalbarri, molluscs, new taxa, Carnarvon Basin, biogeography, Southern Australian Province. INTRODUCTION The source deposit, a pallid to ferruginous silicified Eocene marine molluscan assemblages from sandstone, forms a weakly defined, low breakaway coastal sedimentary basins in southern Australia trending N-S and sloping gently westward. -

Thus, to describe possible phenotypic diversity, a total of 90 venerid bivalves (30 specimens for each species) were photographed on their right valves. Canonical variate analysis (CVA), multivariate analysis of variance (MANOVA), principal component analysis (PCA) and Kruskal-Wallis tests showed significant difference between species based on the Fourier coefficients. This study showed significant variations in the shape of the right external valve of the shell. CVA plot generated show separation of populations examined indicating significant difference between groups. Observed differences in the external shell shapes of different venerid bivalve species were based in the umbo, anterior margin, shell width, length depth and anterior margin depression. Results suggest hypothesized variable factors behind the disparity of the external shell shape which include habitat differences, environment and genotype interactions. Herewith, the use of Elliptic Fourier (EF) analysis proved to be useful in effective quantification of inter-specific variation between species. -
