Minutes of the kick-off meeting of the RMP MARPLAN Stazione Zoologica “A. Dohrn” Naples, Italy, September 23rd, 2005 Written by Raffaella Casotti Present: Gianfranco NOVARINO Jeremy YOUNG Wiebe KOOISTRA Marina MONTRESOR Raffaella CASOTTI Uwe JOHN Wenche EIKREM Bente EDVARDSEN Marta ESTRADA Nathalie SIMON Maria-Luiza PEDROTTI Alina TUNIN Valentina TURK Janja FRANCE Jens HARDER Richard K PIPE Maria JUTSON Costas TSIGENOPOULOS Philippe LEBARON NHM, London NHM, London SZN, Naples SZN, Naples SZN, Naples AWI, Bremerhaven UIO, Oslo UIO, Oslo ICM, Barcelona SBR, Roscoff LOV, Villefranche LOV, Villefranche MBS, Piran MBS, Piran MPI-MM, Bremen MBA, Plymouth MBA, Plymouth HCMR, Heraklion LOBB, Banyuls-sur-Mer During the morning session, several members of the staff and PhD-students of SZN were present to take note of the presentations but the afternoon meeting was restricted to the abovementioned delegates. Wiebe Kooistra of the Stazione Zoologica Anton Dohrn in Naples opened the meeting welcoming the MarPLAN delegates. After a short introduction of the history of the host institute, he briefly recapitulated the origin and objectives of the Responsive Mode Project MarPLAN within MarBEF. The project sprouted from plans for a research and training network (NOMADS) written by Jeremy Young. MarPLAN focuses on research in marine plankton in European waters by means of exchange of knowledge and expertise, by mutual support and by integration of already existing research efforts. To achieve these goals, the 13 partners in MarPLAN have agreed upon a) An exchange program comprising short sabbaticals, b) Provision of specialist training, c) Creation of interdisciplinary collaborations in plankton biodiversity research, d) Calibration of instruments, and e) Exchange of samples and strains. Then he gave the floor to the delegates of the 13 institutes participating in MarPLAN to present facilities and on-going programs of their groups. 1. Gian-Franco Novarino of the Natural History Museum of London highlighted the existing competences in taxonomy and systematics of different groups of nano and microplankton, with an emphasis on haptophytes. Ongoing projects include also the study of feeding and prey recognition of heterotrophic flagellates as well as eco-physiomorpho-molecular diversity of heterotrophic chrysomonads in relation to biogeography. Jeremy Young from the same institute presented additional projects on high quality imaging of coccolithophores, dinoflagellates (live and fossil), and diatoms. 2. Marina Montresor from Stazione Zoologica presented the participants from the institute and their respective competences. She then presented research projects, including an on-going long-term series (30 years) of phytoplankton records at a coastal station in the Gulf of Naples. Genetic and morphological diversity of diatom species (Skeletonema spp. and Pseudo-nitzschia spp.) is also studied, coupled with life cycle investigation to deeper understanding and refining species definition. Also cryptic and pseudocryptic diversity of Pseudo-nitzschia is investigated by means of life cycle and mating experiments. The working group also focuses on diatom phylogeny and taxonomy, and participates in the Marine Genomic Network of Excellence. Flow cytometric competence is available for the project, and can support quantification of species in natural samples and support taxonomical investigations (Casotti). An ancillary project on microzooplankton biodiversity has also been incorporated in MARPLAN (Modigh). 3. Bente Edvardsen, from the University of Oslo, presented the activities of the Biology Department, which holds 8 research programs, including the management of the CEES center for evolutionary and ecological synthesis, experimental, behavioural and population biology, molecular ecology and biosystematics, marine biodiversity, plankton biology and toxicology and ecophysiology, the last three are the more concerned with MARPLAN. She then described the participants within the Plankton Biology Group and the infrastructure, equipment and facilities available to MARPLAN, which include flow cytometry, LSC, EM, DNA sequencing, culture collection, a research vessel, access to coastal sites and laboratories. Research activities include phylogeny, taxonomy and biology, biodiversity and genetic diversity, Harmful algae and toxin production, plankton dynamics and ecological stoichiometry and planktonic food webs. The laboratory focuses on harmful algae among which Chrysochromulina, Prymnesium, Planktothrix (freshwater), Verrucophora, and Dinophysis species. Pico and nanoplankton diversity is also investigated, so is biodiversity and distribution of flagellates. Statistical niche modelling (Generalized Additive Models - GAM) is achieved and cross-validated using thin-plate spline models. These methods aim at calculating the probability of occurrence of one species or gene in certain conditions (applied to long-term series). 4. Uwe John, from the Alfred Wegener Institute of Bremerhaven, Germany stated that the AWI can contribute with its expertise in molecular methods, for examples for phylogenetic and population genetics analysis: from DNA extraction, PCR, sequencing up to analysis for the whole range of planktonic species. There is taxonomic and phylogenetic expertise in diatoms (Linda Medlin and Richard Crawford) and in dinoflagellate phylogeny (Uwe John) Urban Tillmann offer expertise in heterotrophic protist handling and would be interested in sample and experience exchange. A very strong field at the AWI is the long time series on Helgoland, with data for bacteria (Wichels, Gerds), phytoplankton (Wiltshire), and for zooplankton (Boersma). These groups are interested in data exchange, in cooperation, with other long time series and offer to deliver samples of certain isolates. Kraberg is developing a taxonomic platform, which includes taxonomic relevant description and pictures, which are for public use. The group of Linda Medlin (Medlin, Töbe, Metfies) offers tools for diversity identification based on molecular probes. Hierarchical probes are developed for use in whole cell in situ hybridisation and on arrays. Knowledge and data transfer is possible. For testing the diagnostic diversity microarrays, field samples from different European sample sites would be appreciated. Within the group of chemical ecology of Allan Cembella (Cembella, John, Tillmann, Krock), the allelochemical interaction among protists (microbial eukaryotes) are the major focus of research. Therefore they can offer expertise in genetically and phenotypically characterisation of isolates, including phycotoxin measurements with HPLC or LC MS/MS. Phillip Assmy, Joachim Henjes and Victor Smetacek, have a strong focus on off-shore biodiversity and factors influencing bloom formation. Beside their own taxonomic expertise they do have interest in cooperation with taxonomist for data- and knowledge exchange. The AWI groups are interested in short-term sabatticles for learning methods in the field of diversity identification and quantification. 5. Marcel Veldhuis from the Netherlands Institute for Sea Research (NIOZ) at Texel, the Netherlands, could not attend the meeting but Wiebe Kooistra gave the presentation on his behalf. He presented the location and the infrastructure on Texel, its structure and history. He then presented the phytoplankton research team, whose focus is on the structure and functioning of marine pelagic food-web, and the role of low food-web in biogeochemical cycles. The research topic directly related to MARPLAN mainly concerns the seasonality of the polymorphic HAB (Harmful Algal Bloom) Phaeocystis globosa in the coastal waters of the North Sea (intraspecific variability of single cells and colonies, the role of viruses (specific affecting single cells), and the link between small scale differences to functional responses). The approach used involves both in situ and culture work, it uses flow cytometry as main tool of research, coupled with molecular tools. Main goals are to trace the genetic similarities/differences of single cells and two colony cells types over a season, differentiating between haploid/diploid stages, investigating the role of viruses in controlling Phaeocystis populations, and to investigate variations in physiology (viability/photosynthetic activity) among strains. 6. Marta Estrada from Institut de Ciències del Mar, CMIMA (CSIC), Spain, outlined the administrative organization of the institute and presented its main research lines, highlighting the most pertinent to MARPLAN, namely, a) Biology of marine species and populations. Investigation of the structure and function of marine organisms from unicellular microbes to vertebrates, in relation with their environment. b) Biodiversity and dynamics of marine ecosystems. Study of the taxonomical, morphological and functional variability of species, populations, communities and ecosystems. c) Integrated study of littoral systems. Anthropogenic impacts at all levels: modification of the coastline, fishing, contaminants and eutrophication. She then highlighted major results of some projects within these research lines, such as the identification of new species and life cycle phases of coccolithophores, the occurrence and taxonomical diversity of Alexandrium spp., and the study of picoplankton populations at a coastal site along the Catalan coast, achieved using flow cytometry, microscopy, and molecular tools. This last integrated project focuses on the identification and phylogeny of Stramenopiles as well as on their functional role in the marine ecosystem. 7. Nathalie Simon, from the Station Biologique de Roscoff, France, outlined the infrastructure of the institute in terms of equipment and facilities, and then described the structure and the organization of the “Ocean Plankton” research group, which is directly involved in MARPLAN. Within the approaches and tools, she enumerated: Microscopy (TEM, SEM, LM, Confocal, epifluoresence), flow cytometry, molecular tools (sequencing, FISH, qPCR, DGGE), biochemical tools (HPLC, protein analysis) and genomics and bioinformatics. She then gave examples of major results obtained on marine picoeukaryote diversity, the discovery of presumed heterotrophic protists, and the detection and biogeography of novel Alveolates. Another project concerns the occurrence and dominance of Micromonas pusilla in coastal waters. She then presented the participants to the project and the scientific plan of her group during MARPLAN, which concerns a) Ceratium infra-specific phylogeny, in collaboration with the Laboratoire Océanographique de Villefranche b) Micromonas infra-specific diversity (samples for FISH, TEM) and the FISH calibration exercise. The "oceanic plankton team" holds a culture collection (RCC : http://www.sb-roscoff.fr/Phyto/RCC/). The collection holds 651 strains and can provide cultures to partners in the frame of MARPLAN, or also accept the deposit of strains. 8. Valentina Turk, from the Marine Biological Station of the National Institut of Biology in Piran, Slovenia, presented the institute organization and the infrastructure. Among current projects are the investigations of the mucus occurrence in the Adriatic Sea and the possible role of microbial interactions in its generation and maintainance. Available to MARPLAN are the laboratories with basic equipment and a research vessel for coastal studies. In addition, small mesocosms are present. Expectation from MARPLAN include collaboration at different levels, training and exchange, sabaticals, participation to intercalibrations, and exchange of biological material. 9. Maria Luiza Pedrotti from the Laboratoire Océanologique de Villefranche, France, presented the institute organization and dimension, with the facilities available. The research topics include a) marine optics and remote sensing, focusing on the coupling of elements (C, N, P, Si, Fe) in the subtropical gyre in the South Pacific, b) geochemistry, focusing on the effect of nutrients and metals on pelagic systems and the evolution of primary production and pigment diversity in NW Mediterranean Sea (monitoring at DYFAMED site), c) plankton dynamics, focusing on plankton diversity and structure of pelagic food web in relation to trophic transfers and the environment as well as on the role of key species in energy transfer, mainly concerning phytoplankton ecophysiology and modeling (chemostat). Within the institute, the Marine Microbial Ecology group, directly involved in MARPLAN, develops three major topics: a) Factors regulating activities and structure of microbial populations (external forcings, top-down, bottom-up controls), b) Functional and taxonomic diversity in microbial populations: variation in timespace scale, c) Roles of microbes in biogeochemical processes (dynamics of DOM, TEP and CO2). Expertise includes: Specific diversity of ciliates and microphytoplankton, Grazing experiments (predation in microbial community), Effect of nutrients on marines microbes, Diversity and activities of marine bacteria, Roles of viruses, Particulate and dissolved primary production, Particulate and dissolved matter (DOC, TEP), Respiration of microbial communities. She also presented the participants to the program and the equipment available. Participation to the programs includes short-term visits at different sites to investigate the long-term changes in Ceratium (planktonic dinoflagellate) diversity in the Ligurian and Tyrrhenian Sea. Expectations from MARPLAN include exchange of old and recent net samples of microphytoplankton from partners, data mining of hidden literature or data concerning distribution and annual variations of Ceratium. Phylogenetics at specific and subspecific levels in genus Ceratium. The group foresees collaboration with the phytoplankton group of Roscoff on single cell PCR technique to acquire expertise and use equipment. In addition, exchange of samples and participation to calibration exercises on FISH and CARD-FISH are expected focused on two topics: a) the relationship between morphological and taxonomic diversity in tintinnid cilates and b) the bacterioplankton diversity and role in the biogeochemical cycles. 10. Jens Harder from the Max-Planck Institute for Microbiology of Bremen, Germany described the structure of the institute and the facilities present. Ongoing research projects in general aim at studying bacteria of anoxic environments, with three departments involved. The department of Biogeochemistry focuses on Cycling of the elements, regulation and interaction of microbial and geochemical processes, Carbon, nitrogen, sulfur and iron cycles in the sediments and Ecology and physiology of nitrate accumulating bacteria. The department of Microbiology focuses on Cultivation and physiology of bacteria involved in the turnover of carbon, nitrogen, sulfur and iron. The department of Molecular Ecology focuses on Diversity, structure and function of microbial populations by, among others, high resolution localization (FISH techniques) and genome analysis. The institute is also managing the marMIC, an International Max Planck Research School for the Master of Science in Marine Microbiology. The involvement in MARPLAN foresees: a) Short term sabbaticals from and to the institute, b) Partial funding of a PhD student, including 2 short sabbaticals at CSIC, Mallorca, Spain and NHM, London, Great Britain, c) Organization of a workshop on fingerprinting techniques suggested for July 2007 in Bremen. 11. Richard Pipe from the Marine Biological Association of Plymouth, UK, presented the Plymouth Algal Culture Collection, which is one of the oldest algal collections in the world with approximately 300 strains, including 40 Type cultures, in addition to ca. 150 Emiliania huxleyi strains. The cultures are maintained in liquid culture with regular subculturing and the collection distributes approximately 300 culture strains per year. Specific aims of the collection are to: a) Provide strains for other researchers, b) Isolate new strains of microalgae, c) Provide repository for strains, d) Develop training workshops, e) Raise awareness of marine microalgae. Research projects ongoing at the MBA include; the study of carbon & nutrient acquisition pathways across the plasma membrane, calcification in coccolithophores, the responses of diatoms to natural light gradients, calcium transport and homeostasis in coccolithophores, redox processes and iron acquisition in marine phytoplankton, diatom membrane physiology and signaling, functional characterisation of diatom membrane transporters, novel techniques applied to algal cell biology, characterisation of the infection process of E. huxleyi viruses, cloning diatom membrane transporters and trace metal cycling in coastal phytoplankton. The role of the Plymouth Algal Collection within MarPLAN is threefold: a) Repository for strains, b) Offer help & advice on culturing techniques, c) Supply of culture strains. 12. Costas Tsigenopoulos, from the Hellenic Centre for Marine Research, Institute of Marine Biology and Genetics of Crete, Greece, after outlining the history of the institute, highlighted the research objectives, which are the analysis of the diversity of marine life at all levels of biological organisation, from the gene to the ecosystem. This multiparametric approach besides having a basic research interest has important implications for applied sectors, such as environmental protection, fisheries management, genetic improvement in aquaculture, and prediction of the responses of the ecosystem to anthropogenic and natural changes. Main research lines are genetics and molecular biotechnology and biodiversity and ecosystem functioning. After providing insights of the research projects and their objectives, he listed the deliverables to be provided within MARBEF: a) Identification and assignment of species to functional categories; genetic attributes of populations and communities, b) Optimised protocols for Real Time Quantitative PCR diagnosis of species - use as bioindicators for monitoring environmental change, c) Develop environmental genomic libraries as a resource for further characterisation of structural and functional aspects of biodiversity, d) Use the Bioinformatic platform of IMBG towards educational goals in bacterial molecular ecology and genomics. These will give a contribution to low cost and reliable assessment of the marine ecosystems, which will render environmental management and decision making more effective. In addition will provide high-level education on bacterial marine genomics and diversity and allow for applications of biotechnological products to the exploration of extreme environments. 13. Philippe Lebaron, from the Laboratoire Arago at the Observatoire Océanologique de Banyuls, France, presented the location, the current activities and the facilities present at the Institute. He then highlighted the activities of the Microbial Ecology Group, which include a microbial observatory in the Mediterranean Sea and focuses on the role of heterotrophic bacteria in the oceans. The overall philosophy of the group is to link diversity and function. Diversity is approached using four main approaches: Fingerprinting methods: SSCP, Cloning/sequencing/phylogeny/probes, Fluorescent in situ hybridization and Isolation, charaterization, collection and database. Examples have been given of the different approaches with results. Additional tools consist in Cell sorting using FCM, MicroFish and Metaproteomic, the latter relatively recent in the lab. The laboratory has an original and very well equipped cytometric platform, with Transmission electronic microscope (TEM), Confocal laser microscope (CLM), two Flow cytometers and sorters (FCM), Epifluorescence microscope and image analysis system, Solid-phase cytometer (SPC). It is involved in the development of new cytometers. The solid state cytometer principle and examples of applications to marine ecology have been presented. The interest of the institute in MARPLAN include: a) Single cell analysis (FISH / MICROFISH : training, improve protocols, inter-comparison of results between different groups, Cell sorting techniques : training, development of new protocols to improve PCR amplification of sorted cells, to share protocols between groups, Review of techniques and/or applications : different partners could be involved), b) Collection of isolates (mainly bacteria, but also other organisms), aimed at creating environmental collections and databases, c) training, offering to organize in Banyuls a workshop and/or a practical course on FISH/MICROFISH (depending on funding) OR on cytometry techniques using the platform. After the presentations, Jens Harder gave an overview of the training activities within MARBEF, and issues of budget allocation and breakdown. He recommended contacting our institute representatives in MARBEF to know the budget breakdown and financial situation of the institute. As for the local research budget, he made clear that the money should be used mainly for exchanges of personnel, up to three months, including students, but not only, so to facilitate integration within the consortium. The host institute can use up to 500 euros per month for consumables related to the sabbatical. Training courses will be offered via RMPs and the workpackage training. There is an open call for training courses each year and a small central budget to support the courses. Participants can use their MARBEF money for travel and subsidence, and a fee will also be demanded. The three team leaders have already received the money from the central budget to provide training within their respective schemes. If additional funding may become available, the final decision on budget allocation and distribution will be suggested by the SSC and finalized likely at the next General Assembly. The assembly broke from 12:30 to 14:30 for lunch at the SZN cafeteria, and then for short excursions into the Marine Botany department and the SZN Aquarium. At reunion Wiebe Kooistra gave some practical recommendations. Avoid overlap with the Marine Genomics NoE activities, mainly considering that 6 out of 14 MARPLAN participants are also part of Marine Genomics. Also, he recommended giving special emphasis to sabbatical exchanges within MARPLAN. He then proceeded to specific examination of the list of Tasks indicated in the approved MARPLAN project and to people assignments. Task 1: the kick-off meeting We will send the report and one task is already accomplished. Task 2: Short term sabbatical visits to partner institutes within MARPLAN to gain experience in techniques or to use equipment unavailable at the home institutes, and to teach expertise unavailable at the host institute Wiebe Kooistra distributed tables showing the expertise available and in demand in the partner groups. He asked everybody to update the information ASAP. The possibility of organizing training courses on microscopy at NHM is investigated. Raffaella Casotti proposed to include HPLC pigment analysis in the list of expertise needed in biodiversity studies of marine algae. However, although this facility is present in the majority of the institutes participating to MARPLAN, no participant could offer this expertise directly. Wiebe Kooistra advised the delegates to actively pursue the exchange program and show results ASAP since active RMP’s may be rewarded in the future if budget re-allocations occur from inactive members in MarBEF to active ones. Task 3: Calibration of tools to permit comparison of results among groups Philippe Lebaron and Nathalie Simon accepted to lead the calibration exercises on FISH and possibly to organize a course on this technique. Raffaella Casotti proposed to replace the calibration exercise on flow cytometry with a coordinated help on-line to users, so to offer information on available facilities and expertise within MARPLAN and to provide help on specific issues. Participants agreed to collaborate on this issue. Raffaella will take the initiative to install such a network. Uwe John accepted to provide calibration help for Real Time PCR. A discussion developed on the need for calibration for taxonomy and also the presentation of data. Task 4: Exchange of samples and strains Task 5: Donation of strains to culture collections Richard Pipe offered to provide support for culture isolation. Issues on authorship were discussed with regard to providing strains. Delegates accepted to acknowledge the origin of the material used, for example, in papers. It has made clear that such issues must be discussed before the exchange of cultures or other material takes place. After the coffee break, Wiebe Kooistra pointed out that the exchange of material is a thing of bilateral agreements among participants. Richard Pipe accepted to receive and maintain strains, as long as certain prerequisites are met: scientific relevance and taxonomic diversity. As an example, a proposed donation of a hundred cultures of unknown things might meet little enthusiasm. Also, donators must accept that the culture is redistributed to other users upon request. Wiebe Kooistra raised the point of the suggested connection with the CCAP in Oban, which has been the only recommendation made by the MarBEF external reviewers of the project. Jeremy Young mentioned that also AlgoBank-Caen should be contacted because they were active in the project NOMADS. Richard Pipe pointed out that CCAP is already a sister collection of the MBA, and that it has a more commercial focus with respect to the MBA. The origin of strains must be mentioned in the acknowledgement section of the papers, and a pdf file of the paper should be sent to the provider. Nathalie Simon mentioned in her presentation the Roscoff Culture Collection (RCC), which can provide cultures to partners in the frame of MARPLAN, or also accept the deposit of strains. Task 6: Integration and outreach through peer-reviewed papers The proposition waits for further development. Wiebe Kooistra handed out a table listing the taxonomic expertise with various taxonomic groups, as present among the partners. The table also lists lead persons responsible for initializing, and possibly, organizing and coordinating integrating activities, such as writing reviews. He asked to check and adjust the list. Participants accepted the main reference persons for specific taxonomical groups, as listed in the table. Doubts arose for Wichels, whose involvement needs to be confirmed. Marta Estrada pointed out that Ramon Massana’s expertise in heterotrophic flagellates focuses on molecular aspects. Task 7: Presentation of results obtained during MARPLAN exchanges among institutes at conferences Task 8: Writing in collaboration of research proposals Task 9: Organization of workshops and symposia on plankton diversity at conferences Wiebe Kooistra recommends the participants to work to spread the knowledge of MarBEF in general, and of MarPLAN, for example by participating to conferences, use the MarBEF logo, and to acknowledge participation to MarBEF and the RMP MarPLAN in papers. Examples of endorsements are provided on the MarBEF website. Wiebe Kooistra pointed out that MarPLAN institute funds can be used for organizing or finalizing writing of proposals if the team includes several MarPLAN partners, for examples, the Marie Curie Actions. He encourages the participants to do so. Costas Tsigenopoulos stated that HCMR has offered to organize the final workshop in Crete. All participants accepted his proposition. Wiebe Kooistra also advised to explore the possibilities to organize small symposia on MARPLAN outputs within major conferences, as for example meetings of the various Phycological Societies, or ASLO. Jeremy Young, as co-ordinator of haptophyte research within MARPLAN, noted that the haptophyte specialists within the project hoped to organize a workshop on haptophyte life-cycles, provisionally to be held in Barcelona in May 2006 (local hosts Marta Estrada and Lluisa Cros).. Task 10: Writing of activity report Wiebe Kooistra accepted to provide the Steering Committee with one Activity Report every year. He expects a high input from the participants. Wiebe Kooistra announces that coordination will be mainly realized using e-mail, and that the minutes and the presentations of the day will be put on the MARBEF webpage. MARPLAN will also have its own webpage but within the general MARBEF website. Task 11: The daughter project, Planctomycetes in European waters Jens Harder calls for contributions in terms of samples and integration by students’ exchanges. Wiebe Kooistra asked if there were any other issues that needed discussion. None were raised. He then thanked everybody for the enthusiasm and constructive participation in the planning phase of the project and collaborative atmosphere during the meeting. Italia Canettieri is acknowledged for having taken care of organizational matters, Raffaella Casotti for writing the minutes, and the SZN for providing coffee, lunch, tea and technical support. Spot-on at 17:00 Wiebe Kooistra closed the meeting, wished everybody success, a safe trip home and announced that all who stayed were invited to join for dinner in a typical Neapolitan restaurant. The next day, several delegates enjoyed an excursion to Pompeii, not exactly a MarPLAN activity but it certainly served integration.
