[Hintergrund] Der aktuelle globale Bericht des Weltbiodiversitätsrats (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services; IPBES) (IPBES 2019) ist einer der hoch-rangigen internationalen Berichte zu wichtigen Erd- und Umweltfragen, die im UN-Kontext erstellt werden und einen konkreten Bezug zu den UN-Nachhaltigkeitszielen (Sustainable Development Goals, SDGs) haben. Er zeigt, wie stark der Rückgang von Ökosystemleistungen die Lebensgrundlage der Menschen auf der Erde gefährdet: So sind bis zu eine Million Tier- und Pflanzenarten vom Aussterben bedroht. Die IPBES Autor*innen lassen keinen Zweifel daran, dass es einer tiefgreifenden Veränderung unserer Lebens- und Wirtschaftsweise bedarf, um diesem Massensterben Einhalt zu gebieten. Nur durch eine nachhaltige Nutzung ökologischer Ressourcen können wir den Hauptursachen des Biodiversitätsverlusts, der Reduktion von Ökosystemleistungen und der Zerstörung von Lebensräumen, entgegenwirken (IPBES 2019). Die Schlussfolgerungen des globalen IPBES Berichts und anderer IPBES Berichte sind von großer politischer Relevanz. Dadurch, dass die Berichte von 131 nationalen Regierungen mit-getragen werden und die Staaten entlang des gesamten Erstellungsprozesses an den Berichten beteiligt sind (z.B. bei der Auswahl von Themen und Expert*innen, der Einbindung von Stakeholder*innen oder der Zusammenfassung für Entscheidungsträger*innen (IPBES 2012)), erhalten ihre Ergebnisse politisches Gewicht. Dabei ist das nationale Engagement für globale Umweltpolitik und Forschung im Umweltbereich nicht auf IPBES beschränkt. Zwischenstaatliche Organisationen wie der IPCC (Intergovermental Panel on Climate Change), ICES (International Council for the Exploration of the Seas) oder IPBES spielen eine immer größer werdende Rolle in der globalen Umweltpolitik; sie alle besitzen eine zunehmende Deutungs-hoheit sowie politische und gesellschaftliche Autorität (Beck et al. 2014). Die Verleihung des Friedensnobelpreises an den IPCC im Jahr 2007 ist dafür ein deutliches Zeichen (Beck et al. 2014). Während die Berichte dieser Organisationen in globalen Politikprozessen eine wichtige Rolle spielen (z.B. für die Konvention zur Biologischen Vielfalt - CBD), fließen ihre Ergebnisse trotz der Beteiligung nationaler Politikakteur*innen selten in nationale politische Diskurse ein und finden in vielen Bereichen, zum Beispiel der Wirtschaftspolitik, bislang wenig Beachtung. Ein möglicher Grund dafür kann eine unzureichende wissenschaftliche Kontextualisierung auf Basis des nationalen politischen Bedarfes sein. Wir gehen davon aus, dass internationale Umweltberichte und ihre wissenschaftlichen Ergebnisse durch einen partizipativen, dialogorientierten Beratungsansatz für die nationale Politik-beratung aufbereitet werden können, um die Relevanz und die Anwendbarkeit der Ergebnisse zu steigern. Idealerweise mündet ein solcher Beratungsansatz in einen standardisierten Prozess, der nicht nur für einen konkreten Umweltbericht, sondern für eine Vielzahl von Um-weltberichten und Themen angewendet werden kann. Im vorliegenden Diskussionspapier stellen wir zunächst das INTERNAS-Projekt vor, das einen solchen Beratungsansatz entwickelt hat. Der INTERNAS-Prozess wird im Folgenden erläutert und reflektiert. Zusätzlich werden verschiedene in INTERNAS angewandte Einzel-methoden, wie beispielsweise Stakeholderdialoge und digitale Wissens-Repräsentationen (Ontologien) vorgestellt.

During these events, heterotrophic bacterioplankton respond to successional releases of dissolved organic matter as algal cells are lysed. Annual seasonal shifts in the community composition of free-living bacterioplankton follow broadly predictable patterns, but whether similar communities respond each year to bloom disturbance events remains unknown owing to a lack of data sets, employing high-frequency sampling over multiple years. We capture the fine-scale microdiversity of these events with weekly sampling using a high-resolution method to discriminate 16S ribosomal RNA gene amplicons that are >99% identical. Furthermore, we used 2 complete years of data to facilitate identification of recurrent sub-networks of co-varying microbes. We demonstrate that despite inter-annual variation in phytoplankton blooms and despite the dynamism of a coastal–oceanic transition zone, patterns of microdiversity are recurrent during both bloom and non-bloom conditions. Sub-networks of co-occurring microbes identified reveal that correlation structures between community members appear quite stable in a seasonally driven response to oligotrophic and eutrophic conditions. ; PLB is supported by the European Research Council Advanced Investigator grant ABYSS 294757 to Antje Boetius.

"The Science We Need For The Ocean We Want." We are on the threshold of a new and exciting era of discovery in the oceans that will shape the development of human endeavours for decades to come. New insights on the significance of the microscopic scale of ocean life has shown this level affects almost every aspect of our lives (health, food, industry, ecosystems). For society's future, we need to investigate the science of marine microbiomes, integrate the novel technologies discovered and initiate policies that foster truly sustainable marine development. The United Nations will dedicate the next decade to Ocean Science for Sustainable Development. The Decade's vision and mission are consistent with the objective of the Atlantic Ocean Research Alliance (AORA) between the European Union, Canada and the United States, that is to "advance the shared vision of an Atlantic Ocean that is healthy, resilient, safe, productive, understood and treasured, to promote the well-being, prosperity and security of the Atlantic for present and future generations". Relevant to the missions of both AORA and the Decade, here, we outline how the marine microbiome is at the heart of the ocean as a living system, driving its nutrient and biogeochemical cycles, forming the basis of its food webs, performing essential and yet unknown functions in climate regulation, including buffering the effects of global change. Furthermore, the oceans are a largely untapped resource for biodiscovery and the bioeconomy, with a high potential for the development of new products and processes. To ensure early coordination and interoperability guided by a shared vision, we need to bring together science, industry and policy makers to advance the "Next Great Exploration of the Oceans". The following Roadmap is the result of an international cooperative effort between the United States, Canada, and the European Union produced within the AORA framework and consistent with the Galway Statement on Atlantic Ocean Cooperation.

AbstractOne of the biggest challenges in molecular biology is bridging the gap between the known and the unknown coding sequence space. This challenge is especially extreme in microbial systems, where between 40% and 60% of the predicted genes are of unknown function. Discarding this uncharacterized fraction should not be an option anymore. Here, we present a conceptual framework and a computational workflow that bridges this gap and provides a powerful strategy to contextualize the investigations of genes of unknown function. Our approach partitions the coding sequence space removing the known-unknown dichotomy, unifies genomic and metagenomic data and provides a framework to expand those investigations across environments and organisms. By analyzing 415,971,742 genes predicted from 1,749 metagenomes and 28,941 bacterial and archaeal genomes we showcase our approach and its application in ecological, evolutionary and biotechnological investigations. As a result, we put into perspective the extent of the unknown fraction, its diversity, and its relevance in genomic and environmental contexts. By identifying a target gene of unknown function for antibiotic resistance, we demonstrate how a contextualized unknown coding sequence space enables the generation of hypotheses that can be used to augment experimental data. ; The authors thankfully acknowledge the computer resources at MareNostrum and the technical support provided by Barcelona Supercomputing Center (RES-AECT-2014-2-0085), the BMBF795 funded de.NBI Cloud within the German Network for Bioinformatics Infrastructure (de.NBI) (031A537B, 031A533A, 031A538A, 031A533B, 031A535A, 031A537C, 031A534A, 031A532B), the University of Oxford Advanced Research Computing (http://dx.doi.org/10.5281/zenodo.22558) and the MARBITS bioinformatics core at ICM-CSIC.

In the next decade the pressures on ocean systems and the communities that rely on them will increase as multiple stressors of climate change, food security and human activities start to impact. Our ability to manage and sustain our oceans will depend on the data we collect and the information and knowledge generated. Much of the uptake of this knowledge will be outside the ocean domain, for example by policy makers, local Governments, custodians and other organizations, so it is imperative that we democratize or open the access and use of ocean data. This paper looks at how technologies, scoped by standards, best practice and communities of practice, can be deployed to change the way that ocean data is accessed, utilized, value added and transformed into information and knowledge. The current portal-download model which requires the user to know what data exists, where it is stored, in what format and with what processing, limits the uptake and use of ocean data. Using examples from a range of disciplines, a web services model of data and information flows is presented. A framework is described, including the systems, processes and human components, which delivers a radical rethink about the delivery of knowledge from ocean data. A series of vision statements describe parts of the future vision along with a series of recommendations about how this may be achieved. The paper recommends the development of virtual test-beds for end to end development of new data workflows and knowledge pathways. This supports the continued development, rationalization and uptake of standards, creates a platform around which a community of practice can be developed, promotes cross discipline engagement from ocean science through to ocean policy, allows for the commercial sector, including the informatics sector, to partner in delivering outcomes and provides a focus to leverage long term sustained funding. The next ten years will be �make or break� for many ocean systems. The decadal challenge is to develop the governance and co-operative mechanisms to harness emerging information technology to deliver on the goal of generating the information and knowledge required to sustain oceans into the future.

This report presents the outcome of the joint work of PhD students and senior researchers working with DNA-based biodiversity assessment approaches with the goal to facilitate others the access to definitions and explanations about novel DNA-based methods. The work was performed during a PhD course (SLU PNS0169) at the Swedish University of Agricultural Sciences (SLU) in Uppsala, Sweden. The course was co-organized by the EU COST research network DNAqua-Net and the SLU Research Schools Focus on Soils and Water (FoSW) and Ecology - basics and applications. DNAqua-Net (COST Action CA15219, 2016-2020) is a network connecting researchers, water managers, politicians and other stakeholders with the aim to develop new genetic tools for bioassessment of aquatic ecosystems in Europe and beyond. The PhD course offered a comprehensive overview of the paradigm shift from traditional morphology-based species identification to novel identification approaches based on molecular markers. We covered the use of molecular tools in both basic research and applied use with a focus on aquatic ecosystem assessment, from species collection to the use of diversity in environmental legislation. The focus of the course was on DNA (meta)barcoding and aquatic organisms. The knowledge gained was shared with the general public by creating Wikipedia pages and through this collaborative Open Access publication, co-authored by all course participants.
