Synthesize the state of the science of modern planktic foraminifera, from pioneering to ongoing research including their spatial and temporal distribution in the world ocean their calcification mechanisms and shell chemistry and their eco-phenotypical and genotypical variability as a peer-reviewed publication in an open-access journal (deliverable 1). 2. Provide guidelines (cookbooks) in terms of species identification, experimental setup for culture studies, laboratory treatment prior to geochemical analysis (deliverable 2) by identifying existing gaps in the available knowledge in order to direct future research. 3. Establish an active Web-based network in cooperation with ongoing (inter)national research programmes and projects to guarantee an open-access world-wide dissemination of results, data and research plans (deliverable 3). 4. Document the work of the group in a special issue of an open-access journal (deliverable 5) in connection with a specialized symposium with special emphasis on modern ocean change i.e. thermohaline circulation and ocean acidification, during one of the AGU or EGU conferences, ideally held at the joint EGU/AGU meeting (envisaged for 2013 or 2014) and/or at the FORAMS 2014 meeting in Chile (deliverable 4). Co-chairs: Gerald Ganssen (Netherlands) and Michal Kucera (Germany) Other Full Members: Jelle Bijma (Germany), Jonathan Erez (Israel), Elena Ivanova (Russia), Margarita Marchant (Chile), Divakar Naidu (India), Daniela Schmidt (UK), Howard Spero (USA), and Richard Zeebe (USA) Associate Members: Caroline Cleroux (USA/France), Kate Darling ( UK), Lennart de Nooijer (Netherlands), Steve Eggins (Australia), Baerbel Hoenisch (USA), Sangmin Hyun (Korea), Zhimin Jian (China-Beijing), Thorsten Kiefer (Switzerland), Dirk Kroon (UK), Stefan Mulitza (Germany), Frank Peeters (Netherlands), Michael Schulz (Germany), Kazuyo Tachikawa (France), Rashieda Toefy (South Africa), and Jaroslaw Tyszka (Poland) Executive Committee Reporter: Corina Brussaard 2-3 2.1.3 SCOR WG 139 on Organic Ligands – A Key Control on Trace Metal Biogeochemistry in the Ocean Naqvi (2011) Terms of Reference: 1. To inform the Ocean Sciences community of this WG and related objectives via a widely distributed publication in EOS or analogous journal. 2. To summarize published results on all aspects of metal-binding ligands in the oceans (e.g., distributions, chemical structure, sources, sinks, stability constants), and to contribute to the organic ligand database for use in biogeochemical models and for those working in the field (including results from ongoing GEOTRACES, SOLAS and CLIVAR efforts). The summary will be included in a review paper published after year 2, as well as in the database on the proposed website. 3. To expand upon the ligand intercalibration programme, initiated by GEOTRACES, to evaluate key analytical issues with currently employed methodologies and determine how to best link ongoing efforts in trace metal and organic geochemistry to assess natural metal- binding ligand.In a recent intercalibration the preservation of samples for Fe and Cu- organic speciation by freezing at -20°C as been found suitable and will enable to make samples taken during GEOTRACES cruises available to interested scientists. A large intercalibration will thus be possible in the future without additional joint cruises or sampling exercises, but could be performed with samples from several ‘normal stations’ of a GEOTRACES leg. Results from intercalibration efforts will be presented in a manual available via download from the proposed WG website. 4. To identify how best to incorporate published and future data into biogeochemical models. 5. To debate the nature of sampling strategies and experimental approaches employed in laboratory and field efforts in workshops and meeting discussions that are needed to enhance our understanding of the links between the provenance, fate, distribution, and chemistry and biological functions of these organic metal-binding ligands in the oceans. 6. To recommend future approaches to ligand biogeochemistry in a designated symposium, including ongoing GEOTRACES field efforts (i.e., regional surveys and process studies), integration of CLE-ACSV and organic geochemistry techniques, and the need for rapid incorporation of this research in biogeochemical models. Such future recommendations will also be included in the aforementioned downloadable manual on the WG website. 7. To establish a webpage for this SCOR working group, to promote a forum for discussion of ideas and results in form of a blog, soliciting input from the trace metal biogeochemistry, organic geochemistry and modeling communities and provide a platform to propose special sessions on trace metal-binding ligands at international meetings

  • Nanoplankton Protists from the Western Mediterranean Sea. II. Cryptomonads (Cryptophyceae = Cryptomonadea)*
    sm69n1047 4/3/05 20:30 Página 47 SCI. MAR., 69 (1): 47-74 SCIENTIA MARINA 2005 Nanoplankton protists from the western Mediterranean Sea. II. Cryptomonads (Cryptophyceae = Cryptomonadea)* GIANFRANCO NOVARINO Department of Zoology, The Natural History Museum, Cromwell Road, London SW7 5BD, U.K. E-mail: [email protected] SUMMARY: This paper is an electron microscopical account of cryptomonad flagellates (Cryptophyceae = Cryptomon- adea) in the plankton of the western Mediterranean Sea. Bottle samples collected during the spring-summer of 1998 in the Sea of Alboran and Barcelona coastal waters contained a total of eleven photosynthetic species: Chroomonas (sensu aucto- rum) sp., Cryptochloris sp., 3 species of Hemiselmis, 3 species of Plagioselmis including Plagioselmis nordica stat. nov/sp. nov., Rhinomonas reticulata (Lucas) Novarino, Teleaulax acuta (Butcher) Hill, and Teleaulax amphioxeia (Conrad) Hill. Identification was based largely on cell surface features, as revealed by scanning electron microscopy (SEM). Cells were either dispersed in the water-column or associated with suspended particulate matter (SPM). Plagioselmis prolonga was the most common species both in the water-column and in association with SPM, suggesting that it might be a key primary pro- ducer of carbon. Taxonomic keys are given based on SEM. Key words: Cryptomonadea, cryptomonads, Cryptophyceae, flagellates, nanoplankton, taxonomy, ultrastructure.

Without his support, it would not have been possible to complete my disserataion research successfully. I must offer my heartfelt thanks to committee members, Dr. Tao Yan, Dr. Winston Su, and Dr. Yong Li for their willingness to share their space, resource, criticism and recommendations. Dr. Yan provided me lab bench, materials, instruments and his lab notes. During my comprehensive examination, Dr. Su guided me an idea regarding the experiment on the behavior of algal transition. Dr. Li allowed me to use his instruments when I have problems in my lab. Many thanks are also extended to all of members for their assistance in the HOLME 286 lab. I express my gratitude to Bunnie and Joe for helping in lab works and Krispin and Card in field data collection. iii ABSTRACT To address the lake eutrophication problem, a research framework integrating molecular biotechnology with environmental engineering was developed. Initially, the lake-like microcosms (Trophic State-Classified Algal Reactors, TSCARs) were designed and constructed for using scenario assessment. As the results, several patterns of algal growth were observed under many replication experiments performed.

  • High and Specific Diversity of Protists in the Deep-Sea Basins Dominated
    ARTICLE https://doi.org/10.1038/s42003-021-02012-5 OPEN High and specific diversity of protists in the deep-sea basins dominated by diplonemids, kinetoplastids, ciliates and foraminiferans ✉ Alexandra Schoenle 1 , Manon Hohlfeld1, Karoline Hermanns1, Frédéric Mahé 2,3, Colomban de Vargas4,5, ✉ Frank Nitsche1 & Hartmut Arndt 1 Heterotrophic protists (unicellular eukaryotes) form a major link from bacteria and algae to higher trophic levels in the sunlit ocean. Their role on the deep seafloor, however, is only fragmentarily understood, despite their potential key function for global carbon cycling. Using 1234567890():,; the approach of combined DNA metabarcoding and cultivation-based surveys of 11 deep-sea regions, we show that protist communities, mostly overlooked in current deep-sea foodweb models, are highly specific, locally diverse and have little overlap to pelagic communities. Besides traditionally considered foraminiferans, tiny protists including diplonemids, kineto- plastids and ciliates were genetically highly diverse considerably exceeding the diversity of metazoans. Deep-sea protists, including many parasitic species, represent thus one of the most diverse biodiversity compartments of the Earth system, forming an essential link to metazoans. 1 University of Cologne, Institute of Zoology, General Ecology, Cologne, Germany. 2 CIRAD, UMR BGPI, Montpellier, France. 3 BGPI, Univ Montpellier, CIRAD, IRD, Montpellier SupAgro, Montpellier, France. 4 CNRS, Sorbonne Université, Station Biologique de Roscoff, UMR7144, ECOMAP—Ecology of
