JOHN'S NEWFOUNDLAND ABSTRACT: The structure and species diversity of benthic communities were examined fromsamples collected by SCUBA and Shipek grab from sand bottoms on the Labrador coast and in Conception Bay Newfoundland. The effects of the uhysic~l environment on the benthic community were studied using the factors of depth, distance offshore, substrate type, substrate diversity and exposure to open water. Two communities were found in the areas surveyed; one on finer sands in protected environments characterized by Prionospio steenstrupi and Pectinaria granulata and one on coarser sands in more exposed environments characterized by Diastylis sp. and Nephtys longosetosa. Three species found in Labrador, Laonome kroyeri~ Amphiophiura convexa and Onisimus affinis were new records for the Labrador coast. Species diversity was found to be greatest at medium exposures, where heterogeneity of the environment was greatest and on substrates with the greatest diversity of grain sizes. Variations in numbers of species between Newfoundland and Labrador and between sites with similar physical conditions was found to be due to non-burrowing species. Attempts were made to explain differences in number of species for sites on the Labrador coast and between Newfoundland and Labrador sites on the basis of differences in exposure, substrate conditions and predation. lll ACKNOWLEDGEMENTS: I would like to thank my supervisor Dr. D.H.

  • Examining Patterns of Genetic Variation in Canadian Marine Molluscs Through DNA Barcodes
    Examining patterns of genetic variation in Canadian marine molluscs through DNA barcodes by Kara Layton A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Integrative Biology Guelph, Ontario, Canada © Kara Layton, January, 2012 ABSTRACT Examining patterns of genetic variation in Canadian marine molluscs through DNA barcodes Kara Layton Advisor: University of Guelph, 2013 Professor P.D.N Hebert In this thesis I investigate patterns of sequence variation at the COI gene in Canadian marine molluscs. The research presented begins the construction of a DNA barcode reference library for this phylum, presenting records for nearly 25% of the Canadian fauna. This work confirms that the COI gene region is an effective tool for delineating species of marine molluscs and for revealing overlooked species. This study also discovered a link between GC content and sequence divergence between congeneric species. I also provide a detailed analysis of population structure in two bivalves with similar larval development and dispersal potential, exploring how Canada’s extensive glacial history has shaped genetic structure. Both bivalve species show evidence for cryptic taxa and particularly high genetic diversity in populations from the northeast Pacific. These results have implications for the utility of DNA barcoding both for documenting biodiversity and broadening our understanding of biogeographic patterns in Holarctic species. Acknowledgements Firstly, I would like to thank my advisor Dr. Paul Hebert for providing endless guidance and support during my program and for greatly improving my research. You always encouraged my participation in field collections and conferences, allowing many opportunities to connect with colleagues and present my research to the scientific community.

    American Fisheries Society Symposium 41:439–460, 2005 © 2005 by the American Fisheries Society Effects of Commercial Otter Trawling on Benthic Communities in the Southeastern Bering Sea ELOISE J. BROWN,1 BRUCE FINNEY, AND SUE HILLS Institute of Marine Science, University of Alaska Fairbanks, 245 O’Neill Building, Post Office Box 757220, Fairbanks, Alaska 99775, USA MICHAELA DOMMISSE Monash University, Department of Geography and Environmental Science, Post Office Box 11A, Clayton 3168, Australia Abstract. The effects of commercial bottom trawling for yellowfin sole Limanda aspera on benthic communities were investigated in a sandy habitat exposed to high wave and tidal disturbance at 20–30 m depth in the southeastern Bering Sea. We compared an area that has been closed to commercial trawling for 10 years with an adjacent area that is now open to commercial trawling. In addition, we examined the immediate effects of experimental trawling on benthic community structure in the area closed to trawling. The fished area was characterized by reduced macrofauna density, biomass, and richness relative to the closed (unfished) area, but diversity was not different. Interannual variability of macrofauna assemblages was high in the system, yet assemblages in the two areas were distinguished using multivariate analyses and dominant taxa. After 10 years, sessile taxa (e.g., Maldanidae polychaetes) were prevalent in the closed area, and mobile scavengers (e.g., Lysianassidae amphipods) were more common in the fished area. Immediate responses of macrofauna to experimental trawling were subtle (i.e., reduced richness, absence of rare taxa, and patchy changes in assemblage biomass), but no differences were detected relative to controls for density, diversity, or total biomass.

E-mail: [email protected] 2 The Australian Museum, Marine Invertebrates, 6 College Street, NSW 2010, Sydney, Australia 3Corresponding author: Abstract During taxonomic studies on the Trichobranchidae housed at the Australian Museum, Sydney morphological characters of specimens were found to serve taxonomists on four taxonomic levels – family, genus, species and specimen level. The number of neuropodial uncini per torus and abdominal segments, long considered holding information for species determination, proved to be highly variable within species. Characters found to be consistent within species were e.g., the position of nephridial papillae, shape of branchiae and chaetae, and the development of anterior segments and lateral lappets. Also, staining in methyl green resulted in a clear pattern without intraspecific variability in most cases and is since considered a helpful tool for identification of Trichobranchidae. In this study an overview of morphological characters of Trichobranchidae and their information for taxonomy is given based on the trichobranchid collection of the Australian Museum. Additionally, description of a new species Terebellides jitu sp. nov., formerly treated as a variation of Terebellides narribri, is given. The description of T. narribri is revised. Key words: Southern hemisphere, Annelida, Terebellida, Terebellides jitu sp. nov., Terebellides narribri Introduction Trichobranchidae are common polychaetes in shallow and deep waters (Hutchings 2000).

  • Review and Assessment of the Literature on Marine Benthic Molluscs (Amphineura, Bivalvia, Gastropoda) in Newfoundland and Labrador Waters

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.

Mittelhauser Specimens cataloged by: Darrin Kelly Glen Mittelhauser Kit Sheehan Taxonomy assistance: Glen Mittelhauser, Maine Natural History Observatory Anne Favolise, Humboldt Field Research Institute Thomas Trott, Gerhard Pohle P.G. Ross 2 William Procter started work on the survey of the marine fauna of the Mount Desert Island region in the spring of 1926 after a summer’s spotting of the territory with a hand dredge. This work was continued from the last week in June until the first week of September through 1932. The specimens from this collection effort were brought back to Mount Desert Island recently. Although Procter noted that this inventorywas not intended to generate a complete list of all species recorded from the Mount Desert Island area, this inventory is the foundation on which all future work on the marine fauna in the region will build. An inven- tory of this magnitude has not been replicated in the region to date. This publication is the result of a major recovery effort for the collection initiated and funded by Acadia National Park. Many of the specimens in this collection were loosing preservative or were already dried out. Over a two year effort, Maine Natural History Observatory worked closely with Acadia National Park to re-house the collection in archival containers, re-hydrate specimens (through stepped concentrations of ethyl alcohol) that had dried, fully catalog the collection, and update the synonymy of specimens.
