BERGMANS Instituut voor Taxonomische Zoologie (Zoologisch Museum) Plantage Middenlaan 53, Amsterdam The Netherlands SUMMARY Taxonomy and distribution of 14 Recent Australian species of the family Nuculidae Gray, 1824 are described and discussed. Available data on biology and ecology are added. Illustrations and distribution maps of all species are given. The genera Pronucula Hedley, 1902, and Deminucula Iredale, 1931, are considered synonyms of Nucula Lamarck, 1799. Rumptunucula is proposed as a new genus for Pronucula vincentiana Cotton and Godfrey, 1938. Lectotypes are selected for Nucula pusilla Angas, 1877, Nucula micans Angas, 1878, Nucula torresi Smith, 1885, Nucula dilecta Smith, 1891, Nucula hedfeyi Pritchard and Gatliff, 1904, Deminucula praetenta Iredale, 1924, Pronucufa mayi Iredale, 1930, and Pronucula saltator Iredale, 1939. Nucula micans Angas, Nucula hedleyi Pritchard and Gatliff, and Pronucula concentrica Cotton, 1930 are considered synonyms of Nucula pusilla Angas. Pronucula voorwindei Bergmans, 1969 is synonymized with Nucula torresi Smith. Nucula diaphana Prashad, 1932 and Pronucula flindersi Cotton, 1930 are ranked as subspecies of Nucula dilecta Smith. -

Sea bottom was found muddy with high similarity in animal community between stations. Animal community found at Eyrarhlíð was predominantly made of common species found in fjord ecosystems in the Westfjords. Polychaetes were the predominant species with Levinsenia gracilis most abundant and good presence of species from the Maldanidae family (Euchone sp. and Galathowenia oculata). Shannon-Wiener diversity index (loge) resulted under 3 for all stations. AMBI classified the site as slightly disturbed. Considering farming was never done in proximity to this site we assume other natural conditions affect the diversity in this area. Visual and chemical parameters did not show any signs of organic impact. -

This process aims to achieve the Good Environmental Status (GES) through the elaborated 11 Ecological Objectives and their respective common indicators. Since 2008, Contracting Parties to the Barcelona Convention have adopted the EcAp and agreed on a roadmap for its implementation. First phases of the EcAp process led to the accomplishment of 5 steps of the scheduled 7-steps process such as: 1) Definition of an Ecological Vision for the Mediterranean; 2) Setting common Mediterranean strategic goals; 3) Identification of an important ecosystem properties and assessment of ecological status and pressures; 4) Development of a set of ecological objectives corresponding to the Vision and strategic goals; and 5) Derivation of operational objectives with indicators and target levels. -
List of Bivalve Molluscs from British Columbia, Canada
List of Bivalve Molluscs from British Columbia, Canada Compiled by Robert G. Forsyth Research Associate, Invertebrate Zoology, Royal BC Museum, 675 Belleville Street, Victoria, BC V8W 9W2; [email protected] Rick M. Harbo Research Associate, Invertebrate Zoology, Royal BC Museum, 675 Belleville Street, Victoria BC V8W 9W2; [email protected] Last revised: 11 October 2013 INTRODUCTION Classification rankings are constantly under debate and review. The higher classification utilized here follows Bieler et al. (2010). Another useful resource is the online World Register of Marine Species (WoRMS; Gofas 2013) where the traditional ranking of Pteriomorphia, Palaeoheterodonta and Heterodonta as subclasses is used. This list includes 237 bivalve species from marine and freshwater habitats of British Columbia, Canada. Marine species (206) are mostly derived from Coan et al. (2000) and Carlton (2007). Freshwater species (31) are from Clarke (1981). Common names of marine bivalves are from Coan et al. (2000), who adopted most names from Turgeon et al. (1998); common names of freshwater species are from Turgeon et al. (1998). Changes to names or additions to the fauna since these two publications are marked with footnotes. Marine groups are in black type, freshwater taxa are in blue. Introduced (non-indigenous) species are marked with an asterisk (*). Marine intertidal species (n=84) are noted with a dagger (†). Quayle (1960) published a BC Provincial Museum handbook, The Intertidal Bivalves of British Columbia. Harbo (1997; 2011) provided illustrations and descriptions of many of the bivalves found in British Columbia, including an identification guide for bivalve siphons and “shows”. Lamb & Hanby (2005) also illustrated many species. -

Molluscs: Bivalvia Laura A
I Molluscs: Bivalvia Laura A. Brink The bivalves (also known as lamellibranchs or pelecypods) include such groups as the clams, mussels, scallops, and oysters. The class Bivalvia is one of the largest groups of invertebrates on the Pacific Northwest coast, with well over 150 species encompassing nine orders and 42 families (Table 1).Despite the fact that this class of mollusc is well represented in the Pacific Northwest, the larvae of only a few species have been identified and described in the scientific literature. The larvae of only 15 of the more common bivalves are described in this chapter. Six of these are introductions from the East Coast. There has been quite a bit of work aimed at rearing West Coast bivalve larvae in the lab, but this has lead to few larval descriptions. Reproduction and Development Most marine bivalves, like many marine invertebrates, are broadcast spawners (e.g., Crassostrea gigas, Macoma balthica, and Mya arenaria,); the males expel sperm into the seawater while females expel their eggs (Fig. 1).Fertilization of an egg by a sperm occurs within the water column. In some species, fertilization occurs within the female, with the zygotes then text continues on page 134 Fig. I.

Review and Assessment of the Literature on Marine Benthic Molluscs (Amphineura, Bivalvia, Gastropoda) in Newfoundland and Labrador Waters
NAFO Sci. Coun. Studies, 10 93-108 Review and Assessment of the Literature on Marine Benthic Molluscs (Amphineura, Bivalvia, Gastropoda) in Newfoundland and Labrador Waters Kent D. Gilkinson Fudge, Lane and Associates Ltd., 607 Torbay Road P. O. Box 9370, Stn B, St. John's, Newfoundland, Canada A1A 2Y3 Abstract A review of the existing literature on marine benthic molluscs (Amphineura, Bivalvia, Gastropoda) in the Newfoundland-Labrador region indicated that at least 158 species, representing 69 fami lies, have been referenced in reports of scientific investigations. Less than one-third of these reports have appeared in the primary literature, while the remainder exist as manuscript reports and university theses. Several species (e.g. Mytilus edulis and Placopecten magellanicus) have been studied intensively, but most species have received only very cursory attention. Specific inventories of molluscs are rare. Most zoo benthic surveys which include molluscs fall into one of three categories: fisheries-related investigations, resource assessment studies, and environmental impact studies. Additionally, the literature contain numerous academic (university) studies. Analysis of the geographic distribution of research effort indicated that most of the work was concentrated in southeastern Newfoundland (Avalon Peninsula) in proximity to the major institutions at SI.

Abstract: The factors involved in promoting long life are extremely intriguing from a human perspective. In part by confronting our own mortality, we have a desire to understand why some organisms live for centuries and others only a matter of days or weeks. What are the factors involved in promoting long life? Not only are questions of lifespan significant from a human perspective, but they are also important from a paleontological one. Most studies of evolution in the fossil record examine changes in the size and the shape of organisms through time. Size and shape are in part a function of life history parameters like lifespan and growth rate, but so far little work has been done on either in the fossil record. The shells of bivavled mollusks may provide an avenue to do just that. Bivalves, much like trees, record their size at each year of life in their shells. In other words, bivalve shells record not only lifespan, but also growth rate. -

J. Mar. biol.Ass. U.K. (I954) 33, 457-472 457 Printed in Great Britain A COMPARATIVE STUDY OF THE BRITISH SPECIES OF NUCULA AND NUCULANA By J. A. Allen Zoology Department, The University, Glasgow, and the Marine Station, Millport (Plate I and Text-figs. 1-8) The survey of the sublittoral fauna of the Clyde Sea Area from 1949 onwards has shown that five species of the Protobranchiata are abundant throughout this region on a variety of substrata. Pelseneer (1891, 1899, 1911), Heath (1937), and Yonge (1939) have contributed much to the knowledge of the group as a whole, but little comparative work has been done at species level. Verrill & Bush (1897, 1898) studied the shell characters of the American Atlantic species. Moore (193Ia, b) worked on the faecal pellets of the British Nuculidae and attempted to distinguish the species by this means~ while Winckworth (1930,1931), mainly in the light of the latter work, attempted to clarify the nomenclature of these species. Winckworth (1932) lists six British species of the family Nuculidae: Nucula sulcata Bronn, N. nudeus (Linne), N. hanleyi Winckworth, N. turgida Leckenby & Marshall, N. moorei Winck- 'Worth and N. tenuis (Montagu); and four species of the family Nuculanidae: Nuculana minuta (Muller), Yoldiella lucida (Loven), Y. tomlini Winckworth !lD.dPhaseolus pusillus (Jeffreys). All species of Nucula, except N. hanleyi, were taken from the Clyde Sea Area, although the latter species is included in the Clyde fauna list (Scott Elliot, Laurie & Murdoch, 1901). Only Nuculana minuta of the Nuculanidae has been taken on the present survey. Yoldiella tomlini is included in the 19°1 list but is noted as being' insufficiently attested'.
