Description: The evolution of the Pontocaspian lakes and seas (Caspian Sea, Black Sea, Aral Sea) is characterised by major changes in water levels, which developed into a pulsating system of connected and isolated basins. During the late Quaternary (Late Pleistocene and Holocene), these basins have hosted a unique endemic biodiversity that experienced species turnover events. There are indications that the Pontocaspian species diversity is now in demise because of anthropogenic modifications of the ecosystem, such as habitat alteration, poaching, pollution and invasive species. Little data is available on faunal changes and resilience of Pontocaspian species to help discerning the effect of natural drivers and anthropogenic drivers on the endemic fauna, which is of direct relevance for conservation strategies. \nThis thesis aims to characterize species richness and abundance of fossil faunas to establish a baseline for comparison with the changing biodiversity of today. Mollusc species are used as the study group as they easily fossilize and are abundant in the geological record. They inform us about the composition of communities and how they change, and enable us to reconstruct environments (\xe2\x80\x98habitats\xe2\x80\x99). This is necessary in order to compare biodiversity through different time intervals and establish whether comparable habitats existed as those of today. A baseline of Pontocaspian mollusc faunas was achieved by analysing snapshots from the Caspian Sea basin and the Black Sea basin. Caspian mollusc assemblages are analysed from late Pleistocene (corresponding to the late Khazarian, Hyrcanian, early Khvalynian and late Khvalynian regional stages) and pre-20th century Holocene (Novocaspian) assemblages. Black Sea assemblages from the late Neoeuxinian and late Holocene are described. They are both compared with modern day assemblages. \nThis study shows clear indications of a Pontocaspian mollusc diversity crisis. Overall, in the 20th\xe2\x80\x9321st century, Pontocaspian molluscs have experienced a severe decline in species richness and abundance: a strong turnover towards invasive species in the Caspian basin, a strong habitat decline in parts of the Black Sea basin and a total obliteration in the Aral basin. The late Quaternary mollusc fauna snapshots demonstrate that endemic species dominated the Caspian communities with minor contributions of native species until the late Holocene. The Pontocaspian mollusc species richness in the Caspian Sea basin is higher than in the Pontocaspian habitats of the Black Sea basin, or the Aral Sea basin. Throughout the Late Quaternary, the strong natural fluctuations of Caspian Sea level affected shallow water bivalve species of the genus Didacna, but barely changed the overall composition of the mollusc faunas. Late Quaternary mollusc fauna snapshots of the Black Sea basin show very little change in the Pontocaspian species community since humans impacted the habitats. However, the Black Sea Pontocaspian mollusc communities are currently under severe threat of habitat deterioration and destruction. \nThis research indicates that the Caspian Sea could act as a source for Pontocaspian biota, hence conservation efforts are imperative there. The deeper parts (〉50 m water depth) possibly present a (partial) refuge, and urgent research is required to assess these habitats and their faunas. Future research should focus on improving the taxonomic framework to elucidate the identity of some Pontocaspian cryptic and sister species. We need more distribution and ecological data of current Pontocaspian species and more detailed biodiversity time series coupled with detailed environmental proxies to assess the nature of the Pontocaspian biodiversity crisis more comprehensively and plan conservation actions accordingly.

Description: DiSSCo, the Distributed System of Scientific Collections, is a pan-European Research \nInfrastructure (RI) mobilising, unifying bio- and geo-diversity information connected to the \nspecimens held in natural science collections and delivering it to scientific communities and \nbeyond. Bringing together 120 institutions across 21 countries and combining earlier \ninvestments in data interoperability practices with technological advancements in \ndigitisation, cloud services and semantic linking, DiSSCo makes the data from natural \nscience collections available as one virtual data cloud, connected with data emerging from \nnew techniques and not already linked to specimens. These new data include DNA \nbarcodes, whole genome sequences, proteomics and metabolomics data, chemical data, \ntrait data, and imaging data (Computer-assisted Tomography (CT), Synchrotron, etc.), to name but a few; and will lead to a wide range of end-user services that begins with finding, \naccessing, using and improving data. DiSSCo will deliver the diagnostic information \nrequired for novel approaches and new services that will transform the landscape of what \nis possible in ways that are hard to imagine today. \nWith approximately 1.5 billion objects to be digitised, bringing natural science collections to \nthe information age is expected to result in many tens of petabytes of new data over the \nnext decades, used on average by 5,000 \xe2\x80\x93 15,000 unique users every day. This requires \nnew skills, clear policies and robust procedures and new technologies to create, work with \nand manage large digital datasets over their entire research data lifecycle, including their \nlong-term storage and preservation and open access. Such processes and procedures \nmust match and be derived from the latest thinking in open science and data management, \nrealising the core principles of \'findable, accessible, interoperable and reusable\' (FAIR). \nSynthesised from results of the ICEDIG project ("Innovation and Consolidation for Large \nScale Digitisation of Natural Heritage", EU Horizon 2020 grant agreement No. 777483) the \nDiSSCo Conceptual Design Blueprint covers the organisational arrangements, processes \nand practices, the architecture, tools and technologies, culture, skills and capacity building \nand governance and business model proposals for constructing the digitisation \ninfrastructure of DiSSCo. In this context, the digitisation infrastructure of DiSSCo must be \ninterpreted as that infrastructure (machinery, processing, procedures, personnel, \norganisation) offering Europe-wide capabilities for mass digitisation and digitisation-ondemand, \nand for the subsequent management (i.e., curation, publication, processing) and \nuse of the resulting data. The blueprint constitutes the essential background needed to \ncontinue work to raise the overall maturity of the DiSSCo Programme across multiple \ndimensions (organisational, technical, scientific, data, financial) to achieve readiness to \nbegin construction. \nToday, collection digitisation efforts have reached most collection-holding institutions \nacross Europe. Much of the leadership and many of the people involved in digitisation and \nworking with digital collections wish to take steps forward and expand the efforts to benefit \nfurther from the already noticeable positive effects. The collective results of examining \ntechnical, financial, policy and governance aspects show the way forward to operating a \nlarge distributed initiative i.e., the Distributed System of Scientific Collections (DiSSCo) for \nnatural science collections across Europe. Ample examples, opportunities and need for \ninnovation and consolidation for large scale digitisation of natural heritage have been \ndescribed. The blueprint makes one hundred and four (104) recommendations to be \nconsidered by other elements of the DiSSCo Programme of linked projects (i.e., \nSYNTHESYS+, COST MOBILISE, DiSSCo Prepare, and others to follow) and the DiSSCo \nProgramme leadership as the journey towards organisational, technical, scientific, data and \nfinancial readiness continues. \nNevertheless, significant obstacles must be overcome as a matter of priority if DiSSCo is to \nmove beyond its Design and Preparatory Phases during 2024. Specifically, these include: \nOrganisational: \n\xe2\x80\xa2 Strengthen common purpose by adopting a common framework for policy \nharmonisation and capacity enhancement across broad areas, especially in respect \nof digitisation strategy and prioritisation, digitisation processes and techniques, data \nand digital media publication and open access, protection of and access to \nsensitive data, and administration of access and benefit sharing. \n\xe2\x80\xa2 Pursue the joint ventures and other relationships necessary to the successful \ndelivery of the DiSSCo mission, especially ventures with GBIF and other \ninternational and regional digitisation and data aggregation organisations, in the \ncontext of infrastructure policy frameworks, such as EOSC. Proceed with the \nexplicit aim of avoiding divergences of approach in global natural science \ncollections data management and research. \nTechnical: \n\xe2\x80\xa2 Adopt and enhance the DiSSCo Digital Specimen Architecture and, specifically as \na matter of urgency, establish the persistent identifier scheme to be used by \nDiSSCo and (ideally) other comparable regional initiatives. \n\xe2\x80\xa2 Establish (software) engineering development and (infrastructure) operations team \nand direction essential to the delivery of services and functionalities expected from \nDiSSCo such that earnest engineering can lead to an early start of DiSSCo \noperations. \nScientific: \n\xe2\x80\xa2 Establish a common digital research agenda leveraging Digital (extended) \nSpecimens as anchoring points for all specimen-associated and -derived \ninformation, demonstrating to research institutions and policy/decision-makers the \nnew possibilities, opportunities and value of participating in the DiSSCo research \ninfrastructure. \nData: \n\xe2\x80\xa2 Adopt the FAIR Digital Object Framework and the International Image \nInteroperability Framework as the low entropy means to achieving uniform access \nto rich data (image and non-image) that is findable, accessible, interoperable and \nreusable (FAIR). \n\xe2\x80\xa2 Develop and promote best practice approaches towards achieving the best \ndigitisation results in terms of quality (best, according to agreed minimum \ninformation and other specifications), time (highest throughput, fast), and cost \n(lowest, minimal per specimen). \nFinancial \n\xe2\x80\xa2 Broaden attractiveness (i.e., improve bankability) of DiSSCo as an infrastructure to \ninvest in. \n\xe2\x80\xa2 Plan for finding ways to bridge the funding gap to avoid disruptions in the critical \nfunding path that risks interrupting core operations; especially when the gap opens \nbetween the end of preparations and beginning of implementation due to unsolved \npolitical difficulties. \nStrategically, it is vital to balance the multiple factors addressed by the blueprint against \none another to achieve the desired goals of the DiSSCo programme. Decisions cannot be \ntaken on one aspect alone without considering other aspects, and here the various \ngovernance structures of DiSSCo (General Assembly, advisory boards, and stakeholder \nforums) play a critical role over the coming years.

Description: Die Grundstoffindustrie ist ein wichtiger Pfeiler des Wohlstands in Deutschland, sie garantiert Wertschöpfung und sorgt für über 550.000 hochwertige Arbeitsplätze. Um diese für die deutsche Wirtschaft wichtigen Branchen zu erhalten, müssen jetzt die Schlüsseltechnologien für eine CO2-arme Grundstoffproduktion entwickelt und für den großtechnischen Einsatz skaliert werden. Die vorliegende Analyse ist als Ergänzung zu der Studie "Klimaneutrale Industrie: Schlüsseltechnologien und Politikoptionen für Stahl, Chemie und Zement" gedacht. Die 13 in der erwähnten Studie vorgestellten Schlüsseltechnologien werden hier für die technisch interessierten Leserinnen und Leser eingehender beschrieben und diskutiert. Diese Publikation dient als Aufschlag für eine Diskussion über Technologieoptionen und Strategien für eine klimaneutrale Industrie. Alle Daten und Annahmen in dieser Analyse wurden mit Unternehmen und Branchenverbänden intensiv besprochen. Die quantitativen Aussagen sind trotzdem als vorläufig zu betrachten, da sich viele Technologien noch in einer frühen Entwicklungsphase befinden und Abschätzungen über Kosten mit großen Unsicherheiten verbunden sind.

Description: Die Grundstoffindustrie ist ein Pfeiler des Wohlstands in Deutschland, sie garantiert Wertschöpfung und sorgt für über 550.000 hochwertige Arbeitsplätze. Im Ausland steht Made in Germany für höchste Qualität und Innovationsdynamik. Aber: Trotz Effizienz­steigerungen sind die Emissionen der Industrie in den letzten Jahren nicht gefallen und durch die nationalen und internationalen Klimaschutzziele steigt der Druck. Die zentrale Frage lautet daher: Wie kann die Grundstoffindustrie in Deutschland bis spätestens 2050 klimaneutral werden - und gleichzeitig ihre starke Stellung im internationalen Wettbewerbs­umfeld behalten? Agora Energiewende und das Wuppertal Institut haben im Rahmen dieses Projekts in zahlreichen Workshops mit Industrie, Verbänden, Gewerkschaften, Ministerien und der Zivilgesellschaft die Zukunft für eine klimaneutrale Industrie diskutiert und einen Lösungsraum aus technologischen Optionen und politischen Rahmenbedingungen skizziert. In den Workshops wurde deutlich: Die Industrie steht in den Startlöchern, die Herausforderung Klimaschutz offensiv anzugehen. Die fehlenden Rahmenbedingungen und der bisher unzureichende Gestaltungswille der Politik, innovative Instrumente umzusetzen, hindern sie jedoch voranzugehen. Es ist höchste Zeit, dass sich das ändert. Denn jede neue Industrieanlage muss klimasicher sein - schließlich hat sie eine Laufzeit bis weit über das Jahr 2050 hinaus. Diese Publikation soll einen Beitrag dazu leisten, richtungssicher investieren zu können.
