    Targeted Isolation of Tsitsikammamines from the Antarctic Deep-Sea Sponge Latrunculia biformis by Molecular Networking and Anticancer Activity (2018)
    MDPI
    Details
    Publication Date: 2023-05-04
    Description: The Antarctic deep-sea sponge Latrunculia (Latrunculia) biformis Kirkpatrick, 1908 (Class Demospongiae Sollas, Order Poecilosclerida Topsent, Latrunculiidae Topsent) was selected for chemical analyses due to its potent anticancer activity. Metabolomic analysis of its crude extract by HRMS/MS-based molecular networking showed the presence of several clusters of pyrroloiminoquinone alkaloids, i.e., discorhabdin and epinardin-type brominated pyridopyrroloquinolines and tsitsikammamines, the non-brominated bis-pyrroloiminoquinones. Molecular networking approach combined with a bioactivity-guided isolation led to the targeted isolation of the known pyrroloiminoquinone tsitsikammamine A (1) and its new analog 16,17-dehydrotsitsikammamine A (2). The chemical structures of the compounds 1 and 2 were elucidated by spectroscopic analysis (one-dimensional (1D) and two-dimensional (2D) NMR, HR-ESIMS). Due to minute amounts, molecular modeling and docking was used to assess potential affinities to potential targets of the isolated compounds, including DNA intercalation, topoisomerase I-II, and indoleamine 2,3-dioxygenase enzymes. Tsitsikammamines represent a small class of pyrroloiminoquinone alkaloids that have only previously been reported from the South African sponge genus Tsitsikamma Samaai & Kelly and an Australian species of the sponge genus Zyzzya de Laubenfels. This is the first report of tsitsikammamines from the genus Latrunculia du Bocage and the successful application of molecular networking in the identification of comprehensive chemical inventory of L.biformis followed by targeted isolation of new molecules. This study highlights the high productivity of secondary metabolites of Latrunculia sponges and may shed new light on their biosynthetic origin and chemotaxonomy

    Sentinel-1 InSAR Measurements of Elevation Changes over Yedoma Uplands on Sobo-Sise Island, Lena Delta (2018)
    MDPI
    In:  EPIC3Remote Sensing, MDPI, 10(7), pp. 1152, ISSN: 2072-4292
    Details
    Publication Date: 2018-10-15
    Description: Yedoma—extremely ice-rich permafrost with massive ice wedges formed during the Late Pleistocene—is vulnerable to thawing and degradation under climate warming. Thawing of ice-rich Yedoma results in lowering of surface elevations. Quantitative knowledge about surface elevation changes helps us to understand the freeze-thaw processes of the active layer and the potential degradation of Yedoma deposits. In this study, we use C-band Sentinel-1 InSAR measurements to map the elevation changes over ice-rich Yedoma uplands on Sobo-Sise Island, Lena Delta with frequent revisit observations (as short as six or 12 days). We observe significant seasonal thaw subsidence during summer months and heterogeneous inter-annual elevation changes from 2016–17. We also observe interesting patterns of stronger seasonal thaw subsidence on elevated flat Yedoma uplands by comparing to the surrounding Yedoma slopes. Inter-annual analyses from 2016–17 suggest that our observed positive surface elevation changes are likely caused by the delayed progression of the thaw season in 2017, associated with mean annual air temperature fluctuations.

    YOUMARES 8 – Oceans Across Boundaries: Learning from each other: Proceedings of the 2017 conference for YOUng MARine RESearchers in Kiel, Germany (2018)
    Springer
    In:  , ed. by Jungblut, S., Lieblich, V. and Bode, M. Springer, Cham, Switzerland, 251 pp. ISBN 978-3-319-93284-2

    Publication Date: 2021-02-08
    Description: This open access book presents the proceedings volume of the YOUMARES 8 conference, which took place in Kiel, Germany, in September 2017, supported by the German Association for Marine Sciences (DGM). The YOUMARES conference series is entirely bottom-up organized by and for YOUng MARine RESearchers. Qualified early career scientists moderated the scientific sessions during the conference and provided literature reviews on aspects of their research field. These reviews and the presenters’ conference abstracts are compiled here. Thus, this book discusses highly topical fields of marine research and aims to act as a source of knowledge and inspiration for further reading and research.

    Climate Change: Warming Impacts on Marine Biodiversity (2018)
    Springer

    Description: In this chapter, the effects of temperature change—as a main aspect of climate change—on marine biodiversity are assessed. Starting from a general discussion of species responses to temperature, the chapter presents how species respond to warming. These responses comprise adaptation and phenotypic plasticity as well as range shifts. The observed range shifts show more rapid shifts at the poleward range edge than at the equator-near edge, which probably reflects more rapid immigration than extinction in a warming world. A third avenue of changing biodiversity is change in species interactions, which can be altered by temporal and spatial shifts in interacting species. We then compare the potential changes in biodiversity to actual trends recently addressed in empirical synthesis work on local marine biodiversity, which lead to conceptual issues in quantifying the degree of biodiversity change. Finally we assess how climate change impacts the protection of marine environments.

    Description: Bereits zum zweiten Mal wird im Rahmen des KlimaCampus Hamburg der aktuelle Forschungsstand zum Klimawandel in der Hamburger Metropolregion und Norddeutschland systematisch dokumentiert. Erfahren Sie auf Basis der Fachliteratur, in welchem Maße Konsens hinsichtlich des Klimawandels in Norddeutschland besteht. Inwieweit sind Entwicklungen bereits messbar, welche Auswirkungen zeigen sich bereits heute und wie kann sich die Region vor negativen Folgen des Klimawandels schützen? Die über 70 Autoren haben die Forschungsergebnisse zu diesen Fragen systematisch zusammengetragen. Die Übereinstimmung bzw. Widersprüchlichkeit des derzeitigen Wissens wurde dabei herausgearbeitet, Erkenntnisgewinne gegenüber dem ersten Hamburger Klimabericht lokalisiert und weiterhin bestehender Forschungsbedarf aufgezeigt. Alle Beiträge wurden einem wissenschaftlichen Begutachtungsprozess unterzogen, der von einem Lenkungsausschuss überwacht wurde. Die Dokumentation belegt umfassend eine bereits stattfindende Erwärmung in der Metropolregion Hamburg und in Norddeutschland sowie einen Meeresspiegelanstieg an Nord- und Ostsee. Mit der Erwärmung zeichnen sich deutliche Änderungen im Ökosystem ab. Diese bereits eingetretenen Entwicklungen können sich künftig weiter verstärken. Erfahren Sie, welche Auswirkungen dies für Politik, Wirtschaft und Gesellschaft hat.
