    Substantive implementation of article 29 of directive 2008/98/EC : scientific-technical foundation for a national waste prevention programme (2013)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-02-18
    Description: Based on the European Waste Framework Directive and the German Recycling Management Act of 01.06.2012 the objectives for a national waste prevention programme were defined. As main objective, according to art. 1 WFD, the "prevention or reduction of the disadvantageous impacts of waste generation and management on the human health and the environment" is recommended. Indicators for a quantitative and qualitative monitoring are derived for both, the individual measures as well as for a waste prevention programme.

    Genome variations associated with viral susceptibility and calcification in Emiliania huxleyi (2013)
    PUBLIC LIBRARY SCIENCE
    In:  EPIC3PLoS ONE, PUBLIC LIBRARY SCIENCE, 8(11)(e80684), ISSN: 1932-6203

    Description: Emiliania huxleyi, a key player in the global carbon cycle is one of the best studied coccolithophores with respect to biogeochemical cycles, climatology, and host-virus interactions. Strains of E. huxleyi show phenotypic plasticity regarding growth behaviour, light-response, calcification, acidification, and virus susceptibility. This phenomenon is likely a consequence of genomic differences, or transcriptomic responses, to environmental conditions or threats such as viral infections. We used an E. huxleyi genome microarray based on the sequenced strain CCMP1516 (reference strain) to perform comparative genomic hybridizations (CGH) of 16 E. huxleyi strains of different geographic origin. We investigated the genomic diversity and plasticity and focused on the identification of genes related to virus susceptibility and coccolith production (calcification). Among the tested 31940 gene models a core genome of 14628 genes was identified by hybridization among 16 E. huxleyi strains. 224 probes were characterized as specific for the reference strain CCMP1516. Compared to the sequenced E. huxleyi strain CCMP1516 variation in gene content of up to 30 percent among strains was observed. Comparison of core and non-core transcripts sets in terms of annotated functions reveals a broad, almost equal functional coverage over all KOG-categories of both transcript sets within the whole annotated genome. Within the variable (non-core) genome we identified genes associated with virus susceptibility and calcification. Genes associated with virus susceptibility include a Bax inhibitor-1 protein, three LRR receptor-like protein kinases, and mitogen-activated protein kinase. Our list of transcripts associated with coccolith production will stimulate further research, e.g. by genetic manipulation. In particular, the V-type proton ATPase 16 kDa proteolipid subunit is proposed to be a plausible target gene for further calcification studies.

    Community infrastructure and repository for marine magnetic identifications (2014)
    Wiley

    Description: Magnetic anomaly identifications underpin plate tectonic reconstructions and form the primary dataset from which age of the oceanic lithosphere and seafloor spreading regimes in the ocean basins can be determined. Although these identifications are an invaluable resource, their usefulness to the wider scientific community has been limited due to the lack of a central community infrastructure to organize, host and update these interpretations. We have developed an open-source, community-driven online infrastructure as a repository for quality-checked magnetic anomaly identifications from all ocean basins. We provide a global sample dataset that comprises 96,733 individually picked magnetic anomaly identifications organized by ocean basin and publication reference, and provide accompanying Hellinger-format files, where available. Our infrastructure is designed to facilitate research in plate tectonic reconstructions or research that relies on an assessment of plate reconstructions, for both experts and non-experts alike. To further enhance the existing repository and strengthen its value, we encourage others in the community to contribute to this effort.

    The association of Antarctic krill Euphausia superba with the under-ice habitat (2012)
    PUBLIC LIBRARY SCIENCE
    In:  EPIC3PLoS ONE, PUBLIC LIBRARY SCIENCE, 7(2), pp. e31775, ISSN: 1932-6203

    Description: The association of Antarctic krill Euphausia superba with the under-ice habitat was investigated in the Lazarev Sea (Southern Ocean) during austral summer, autumn and winter. Data were obtained using novel Surface and Under Ice Trawls (SUIT), which sampled the 0–2 m surface layer both under sea ice and in open water. Average surface layer densities ranged between 0.8 individuals m−2 in summer and autumn, and 2.7 individuals m−2 in winter. In summer, under-ice densities of Antarctic krill were significantly higher than in open waters. In autumn, the opposite pattern was observed. Under winter sea ice, densities were often low, but repeatedly far exceeded summer and autumn maxima. Statistical models showed that during summer high densities of Antarctic krill in the 0–2 m layer were associated with high ice coverage and shallow mixed layer depths, among other factors. In autumn and winter, density was related to hydrographical parameters. Average under-ice densities from the 0–2 m layer were higher than corresponding values from the 0–200 m layer collected with Rectangular Midwater Trawls (RMT) in summer. In winter, under-ice densities far surpassed maximum 0–200 m densities on several occasions. This indicates that the importance of the ice-water interface layer may be under-estimated by the pelagic nets and sonars commonly used to estimate the population size of Antarctic krill for management purposes, due to their limited ability to sample this habitat. Our results provide evidence for an almost year-round association of Antarctic krill with the under-ice habitat, hundreds of kilometres into the ice-covered area of the Lazarev Sea. Local concentrations of postlarval Antarctic krill under winter sea ice suggest that sea ice biota are important for their winter survival. These findings emphasise the susceptibility of an ecological key species to changing sea ice habitats, suggesting potential ramifications on Antarctic ecosystems induced by climate change.

    Climate change mitigation in emerging economies : from potentials to actions (2013)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-02-18
    Description: This report provides an overview of current activities regarding climate change mitigation in six emerging economies: Brazil, China, India, Mexico, South Africa and South Korea. We cover the institutional set up, measurement, reporting and verification systems for greenhouse gases and mitigation policies and measures. The analysis also addresses existing barriers to mitigation and considers where the international community could provide support to remove these.

    Kosten- und Modellvergleich langfristiger Klimaschutzpfade (bis 2050) : Endbericht (2014)

    Details
    Publication Date: 2022-02-18
    Description: Zielsetzung des Forschungsprojektes war es, Klimaschutzszenarien für Deutschland zu entwickeln, die hinsichtlich ihres klimapolitischen Ziels, d.h. ihres langfristigen Emissionsminderungsbeitrags, im Wesentlichen gleich sind, die aber zum Teil auf unterschiedliche Optionen zur Reduktion der energiebedingten CO2-Emissionen setzen. Diese Klimaschutzszenarien wurden hinsichtlich sozioökonomischer und ökologischer Kriterien evaluiert und miteinander verglichen.
