Seasonal Variation in the Occurrence of Planktic Bivalve Larvae in the Schleswig-Holstein Wadden Sea
HELGOLdkNDER MEERESUNTERSUCHUNGEN Helgolander Meeresunters. 51, 23-39 {1997} Seasonal variation in the occurrence of planktic bivalve larvae in the Schleswig-Holstein Wadden Sea Andrea Pulfrich* Institut ffir Meereskunde; Dfisternbrooker Weg 20, 24105 Kiel, Germany ABSTRACT: In the late 1980s, recruitment failures of the mussel Mytilus edulis led to economic pro- blems in the mussel fishing and cultivation industries of northwestern Europe. As part of a collabo- rative study to gain a better understanding of the mechanisms affecting recruitment processes of mussels, plankton samples were collected regularly over a four-year period (t990-I993) from three stations in the Schleswig-Holstein Wadden Sea. The bivalve component of the plankton was domi- nated by the Solenidae, which was almost exclusively represented by Ensis americanus [= directus). NI. eduhs was the second most abundant species. Abundances of mussel larvae peaked 2 to 4 weeks after spawning maxima in the adult populations. Although variations in timing and amplitude of the tota~ [arvaL densities occurred, annua[ abuadances o[M. edulis larvae remained stable during the study period, and regional abundance differences were insignificant. A close relaUonsh~p was found between peaks in larval abundance and phytoplankton blooms. Differences in larval concentrations in the ebb and the flow currents were insignificant. Planktic mussel larvae measured between 200 }am and 300 ~tm, and successive cohorts were recognizable in the majority of samples. Most lar- vae were found to originate from local stocks, although imports from outside the area do occur. INTRODUCTION Successive years of failing spatfall and recruitment of the edible mussel Mytilus edu- lis L. (Bivalvia) on the northwestern European coast during the late 1980s caused sub- stantial production Losses in the mussel fishing and cultivation industries. -
Processing of 13C-Labelled Phytoplankton in a Fine-Grained Sandy-Shelf Sediment (North Sea): Relative Importance of Different Macrofauna Species
MARINE ECOLOGY PROGRESS SERIES Vol. 297: 61–70, 2005 Published August 1 Mar Ecol Prog Ser Processing of 13C-labelled phytoplankton in a fine-grained sandy-shelf sediment (North Sea): relative importance of different macrofauna species Anja Kamp1, 2,*, Ursula Witte1, 3 1Max Planck Institute for Marine Microbiology, Celsiusstr. 1, 28359 Bremen, Germany 2Present address: Institute for Microbiology, University of Hannover, Schneiderberg 50, 30167 Hannover, Germany 3Present address: Oceanlab, University of Aberdeen, Newburgh, Aberdeen AB41 6AA, UK ABSTRACT: On-board and in situ experiments with 13C-labelled diatoms were carried out to inves- tigate the processing of algal carbon by the macrofauna community of a fine sandy-shelf site in the southern German Bight (North Sea). The time series (12, 30, 32 and 132 h incubations) was supple- mented by additional laboratory experiments on the role of the dominant macrofauna organism, the bivalve Fabulina fabula (Bivalvia: Tellinidae), for particulate organic matter subduction to deeper sediment layers. The specific uptake of algal 13C by macrofauna organisms was visible after 12 h and constantly increased during the incubation periods. F. fabula, a facultative (surface) deposit- and suspension-feeder, Lanice conchilega (Polychaeta: Terebellidae), a suspension-feeder and the (sur- face) deposit-feeder Echinocardium cordatum (Echinodermata: Spatangidae) were responsible for the majority of macrofaunal carbon processing. Predatory macrofauna organisms like Nephtys spp. (Polychaeta: Nephtyidae) also quickly became labelled. The rapid subduction of fresh organic matter by F. fabula down to ca. 4 to 7 cm sediment depth could be demonstrated, and it is suggested that entrainment by macrofauna in this fine-grained sand is much more efficient than advective transport. -

Jewett Institute of Marine Science University of Alaska Fairbanks, Alaska 99701 Final Report Outer Continental Shelf Environmental Assessment Program Research Unit 517 October 1977 279 We thank the following for assistance during this study: the crew of the MV Big Valley; Pete Jackson and James Blackburn of the Alaska Department of Fish and Game, Kodiak, for their assistance in a cooperative benthic trawl study; and University of Alaska Institute of Marine Science personnel Rosemary Hobson for assistance in data processing, Max Hoberg for shipboard assistance, and Nora Foster for taxonomic assistance. This study was funded by the Bureau of Land Management, Department of the Interior, through an interagency agreement with the National Oceanic and Atmospheric Administration, Department of Commerce, as part of the Alaska Outer Continental Shelf Environment Assessment Program (OCSEAP). SUMMARY OF OBJECTIVES, CONCLUSIONS, AND IMPLICATIONS WITH RESPECT TO OCS OIL AND GAS DEVELOPMENT Little is known about the biology of the invertebrate components of the shallow, nearshore benthos of the bays of Kodiak Island, and yet these components may be the ones most significantly affected by the impact of oil derived from offshore petroleum operations. Baseline information on species composition is essential before industrial activities take place in waters adjacent to Kodiak Island. It was the intent of this investigation to collect information on the composition, distribution, and biology of the epifaunal invertebrate components of two bays of Kodiak Island. The specific objectives of this study were: 1) A qualitative inventory of dominant benthic invertebrate epifaunal species within two study sites (Alitak and Ugak bays). -

Sample Size Effects on the Assessment of Eukaryotic Diversity

A. Nascimento 1,4, Delphine Lallias2, Holly M. Bik 3 & Simon Creer 4 Understanding how biodiversity changes in time and space is vital to assess the efects of environmental change on benthic ecosystems. Due to the limitations of morphological methods, there has been a rapid expansion in the application of high-throughput sequencing methods to study benthic eukaryotic communities. However, the efect of sample size and small-scale spatial variation on the assessment of benthic eukaryotic diversity is still not well understood. Here, we investigate the efect of diferent sample volumes in the genetic assessment of benthic metazoan and non-metazoan eukaryotic community composition. Accordingly, DNA was extracted from fve diferent cumulative sediment volumes comprising 100% of the top 2 cm of fve benthic sampling cores, and used as template for Ilumina MiSeq sequencing of 18 S rRNA amplicons. Sample volumes strongly impacted diversity metrics for both metazoans and non-metazoan eukaryotes. Beta-diversity of treatments using smaller sample volumes was signifcantly diferent from the beta-diversity of the 100% sampled area. Overall our fndings indicate that sample volumes of 0.2 g (1% of the sampled area) are insufcient to account for spatial heterogeneity at small spatial scales, and that relatively large percentages of sediment core samples are needed for obtaining robust diversity measurement of both metazoan and non-metazoan eukaryotes. -

Project Summary relative to deliverables and scope of work [Note: Figures are in Appendix 1, Tables in Appendix 2.] Preface Due to the information generated by this project funded by the Chesapeake Bay Trust (CBT), we were successful in competing for two subsequent grants, one for $40,000 from the Chesapeake Research Consortium (CRC) and a second for $1,000,000 from the Department of Defense’s Readiness and Environmental Protection Integration (REPI) Challenge Grant program. In addition, we submitted an additional proposal for $140,000 to the Chesapeake Bay Cooperative Ecosystem Studies Unit. All three of these are to conduct shoreline and habitat restoration at the Naval Weapons Station Yorktown as part of a comprehensive restoration program that also involves the shoreline of the National Park Service’s Colonial National Historical Park. Objective 1: Develop a shovel-ready living shoreline restoration plan and monitoring protocols.
