ZERO BRINE – Industrial Wastewater – Resource Recovery – Circular Economy 2 Executive summary Seawater desalination plants may potentially affect the aquatic biological communities in the coastal environment due to the brine discharge. “Benthic macroinvertebrates” is the key biological indicator examined in this investigation for the assessment of the influence of brine discharge on benthic fauna, supported by data about macroalgal indicators and physicochemical and hydromorphological conditions. Benthic macroinvertebrates have an important role in sediment processes and predator– prey relationships and they usually have well-defined responses to environmental changes, especially those stressors that influence the sediment structure and its chemistry and quality. They are officially included among biological quality elements in the European umbrella regulations for water systems, namely the Water Framework Directive 2000/60/EC (WFD) and the Marine Strategy Framework Directive 2008/56/EC (MSFD). The investigated area includes three sites, one in the vicinity of the EVIDES DWP1 in the Britanniehaven area, one in the vicinity of EVIDES DWP2 in the Hartelkanaal area, and one in Hartelkanaal in the Elbeweg area that is designated as reference site. In total, 4 seasonal sampling surveys were scheduled, namely in September 2019, January 2020, July 2020 and April 2021. The survey planned for April 2020 was cancelled due to the Covid-19 outbreak and postponed for April 2021. A total of 6 sampling stations have been established for benthic macroinvertebrates analysis. Biological quality descriptors (abundance A, species richness S, and Shannon’s diversity H), biological quality indices (AMBI, BOPA), and statistics analysis tools will be applied after the completion of the surveys to objectively assess the effect of brine release on benthic fauna and the ecological status of the investigated areas. The approach will be in line with the guidelines of the WFD and the MSFD.

  • Early Ontogeny of Jurassic Bakevelliids and Their Bearing on Bivalve Evolution
    Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution NIKOLAUS MALCHUS Malchus, N. 2004. Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution. Acta Palaeontologica Polonica 49 (1): 85–110. Larval and earliest postlarval shells of Jurassic Bakevelliidae are described for the first time and some complementary data are given concerning larval shells of oysters and pinnids. Two new larval shell characters, a posterodorsal outlet and shell septum are described. The outlet is homologous to the posterodorsal notch of oysters and posterodorsal ridge of arcoids. It probably reflects the presence of the soft anatomical character post−anal tuft, which, among Pteriomorphia, was only known from oysters. A shell septum was so far only known from Cassianellidae, Lithiotidae, and the bakevelliid Kobayashites. A review of early ontogenetic shell characters strongly suggests a basal dichotomy within the Pterio− morphia separating taxa with opisthogyrate larval shells, such as most (or all?) Praecardioida, Pinnoida, Pterioida (Bakevelliidae, Cassianellidae, all living Pterioidea), and Ostreoida from all other groups. The Pinnidae appear to be closely related to the Pterioida, and the Bakevelliidae belong to the stem line of the Cassianellidae, Lithiotidae, Pterioidea, and Ostreoidea. The latter two superfamilies comprise a well constrained clade. These interpretations are con− sistent with recent phylogenetic hypotheses based on palaeontological and genetic (18S and 28S mtDNA) data. A more detailed phylogeny is hampered by the fact that many larval shell characters are rather ancient plesiomorphies. Key words: Bivalvia, Pteriomorphia, Bakevelliidae, larval shell, ontogeny, phylogeny.

  • Structure and Distribution of Chalky Deposits in the Pacific Oyster Using
    www.nature.com/scientificreports OPEN Structure and distribution of chalky deposits in the Pacifc oyster using x‑ray computed tomography (CT) Roxanne M. W. Banker* & Dawn Y. Sumner Oysters are unusual among bivalves in that they possess chambers, often flled with soft, chalky calcite, that are irregularly scattered throughout the shell. Because the function of these so‑called chalky deposits is still unclear, evaluating the growth and distribution of chalk is important for elucidating the ecological function of this unique shell trait. Specimens of the Pacifc oyster Magallana gigas, an oyster well known for chalk expression, were grown in Bodega Harbor, Bodega Bay, CA. At the end of an 11 month growing period, specimens were culled and selected animals were submitted for x‑ray computed‑tomography imaging. Three‑dimensional reconstructions of oyster shells were used to assess the overall distribution of chalk, and also to better understand the relationship between chalk and other structures within the shell. Results indicate that chalky deposits underly sculptural features on the shell exterior, such as external ridges and changes in growth direction, and also that there is a relationship between chalk formation and oyster processes of cementation. Overall, chalk is useful for a cementing lifestyle because it enables morphological plasticity needed to conform to irregular substrates, but also acts as a cheap building material to facilitate rapid growth. Many researchers have used preserved remains of shells (molluscan or otherwise) to improve scientifc under- standing of paleoecosystems and organismal interactions in the fossil record1–3. Oysters (Bivalvia: Ostreidae) have utility in this setting because they are well preserved in the fossil record, and are widely geographically dis- tributed in paleo and modern ecosystems4.

  • Variation of Sperm Morphology in Pacific Oyster Precludes Its Use As a Species Marker but Enables Intraspecific Geo-Authentifica
    Reunov et al. Helgol Mar Res (2018) 72:8 https://doi.org/10.1186/s10152-018-0510-x Helgoland Marine Research ORIGINAL ARTICLE Open Access Variation of sperm morphology in Pacifc oyster precludes its use as a species marker but enables intraspecifc geo‑authentifcation and aquatic monitoring Arkadiy Reunov1,2*, Evgenia Vekhova2, Evgeny Zakharov3, Yulia Reunova2, Yana Alexandrova2, Svetlana Sharina2,4 and Andrey Adrianov2,4 Abstract According to recent reports, shell morphology is unreliable for the identifcation of oysters because of the high phe- notypic plasticity of these bivalves. Using COI DNA barcoding and sperm morphology, we reinvestigated the species validity of wild Pacifc oyster Crassostrea gigas habituating the Peter the Great Bay (Sea of Japan). DNA barcoding con- frmed the species validity of samples collected. Application of the single sperm pattern was not possible for species identifcation due to pronounced sperm plasticity being found. Six sperm morphs were discovered in the testes of each oyster collected. The amount of abundant sperm morphs and the type of the most dominant sperm pattern are particular to geographical localities that are individual depending on the environmental factors. Ecological monitor- ing of marine areas and commercially assigned intraspecifc geo-authentifcation of the Pacifc oyster seems possible based on the analysis of this species’ heterogenic sperm. Further work will be needed to test if sperm heterogeneity exists in other Ostreidae species and if heterogenic sperms could be used for interspecifc analysis.
