    Helmholtz Open Science Briefing: Helmholtz in der Nationalen Forschungsdateninfrastruktur (NFDI): Report des Helmholtz Open Science Forums (2021)
    Helmholtz Open Science Office
    In:  Helmholtz Open Science Briefing
    Details
    Publication Date: 2022-01-19
    Description: Mit der Nationalen Forschungsdateninfrastruktur (NFDI) verfolgen Bund und Länder das Ziel, Datenbestände aus der Forschung für das deutsche Wissenschaftssystem nach den FAIR-Prinzipien systematisch zu erschließen, damit diese für Dritte besser zugänglich gemacht werden. Die NFDI wird als Netzwerk von Konsortien über einen Zeitraum von drei Jahren ab 2020 in drei aufeinanderfolgenden Förderphasen aufgebaut. Eine wichtige Rolle spielt dabei auch die Abdeckung disziplinübergreifender Querschnittsthemen. Zur Förderung des Dialogs zur NFDI in der Helmholtz-Gemeinschaft veranstaltete das Helmholtz Open Science Office am 4. Mai 2021 ein digitales Helmholtz Open Science Forum unter dem Motto „Helmholtz in der Nationalen Forschungsdateninfrastruktur (NFDI)“. Als Impuls für die weitere Diskussion lud das Helmholtz Open Science Office alle interessierten Mitarbeitenden der Helmholtz-Gemeinschaft zu diesem virtuellen Helmholtz Open Science Forum ein. Neben einer Einführung durch das NFDI-Direktorat stellten Vorträge die Bandbreite der NFDI-Beteiligung in Helmholtz dar (z. B. Praxisberichte bereits bewilligter Konsortien sowie Vorträge zum Umgang mit der NFDI aus Perspektive eines Zentrums, eines Forschungsbereichs und einer Plattform des Inkubators “Information & Data Science”); auch wurde das Zusammenspiel von NFDI und European Open Science Cloud (EOSC) vom Büro Brüssel der Gemeinschaft beleuchtet. Im Kern stand die Identifikation und Diskussion zu Helmholtz-spezifischen Aspekten bei der Realisierung der NFDI.

    Publication Date: 2022-03-23
    Description: Zum Austausch von Best Practices aus den Zentren und zur Förderung der FDM-Community in Helmholtz veranstaltete das Helmholtz Open Science Office am 3. Februar 2022 das erste „Helmholtz Open Science Praxisforum Forschungsdatenmanagement“. In dem Helmholtz-internen Forum wurden exemplarisch verschiedene Herangehensweisen aus Zentren zur Organisation des FDM vorgestellt. Darüber hinaus standen konkrete Service-Angebote zu FDM im Mittelpunkt. Außerdem wurde die Vernetzung mit externen Akteuren, z. B. im Rahmen der NFDI, EOSC oder der RDA, beleuchtet. Die regen Diskussionen verdeutlichten den hohen Bedarf nach übergreifendem Community-Building im Bereich des FDM innerhalb von Helmholtz und darüber hinaus.

    Hypoxia tolerance and exercise of an Arctic key stone species the Polar cod Boreogadus saida under global change scenarios (2021)
    University of Bremen
    In:  EPIC3University of Bremen, 95 p.
    Details
    Publication Date: 2022-01-07
    Description: The Arctic is the region on Earth expected to experience the highest rate of warming caused by climate change. Ocean warming is directly and indirectly decreasing oxygen concentration in the ocean, therewith confronting marine biota with a change of two crucial abiotic factors. Polar cod Boreogadus saida is an Arctic key stone species due to its central position in the food web. In order to contribute to a better understanding of its upper thermal limits and the synergistic effects of warming and decreasing oxygen availability on its metabolic and swimming capacity, Polar cod were acclimated to a temperature hypothesised to belong to its upper thermal limit (10°C) over 10 months. Using static and swim tunnel respirometry 10°C were found to clearly belong to the pejus temperature range of Polar cod although aerobic scope and swimming capacity were maintained at this temperature. No metabolic compensation was observed for standard metabolic rate that increased by a factor of five. A significant PO2 effect on maximum metabolic rate and aerobic scope was observed when measuring metabolic and swimming capacity at decreasing ambient oxygen levels. Polar cod displayed oxy regulation over the whole PO2 range tolerated. Critical velocity stayed stable until 40% ambient O2 saturation whereas gait transition velocity decreased non-significantly at 50% O2. Temperature had a strong negative effect on hypoxia tolerance by increasing Pcmax and Pcrit to 12.53 and 5.22 kPa O2, respectively. We observed that water masses of 10°C can be tolerated in short-term by Polar cod but do not allow for population survival. Hypoxia tolerance was found to be strongly decreased at the long-term incubation temperature but still remained high in inter-species comparison and with respect to 10°C as pejus temperature. Future research should address hypoxia tolerance of Polar cod during acute warming to understand the physiological impacts during marine heatwaves.

    Description: The proposed recommendations are seen as a logical development of research aimed at assessing the state of the resource base and catch forecasting for brine shrimp and brine shrimp at the stage of cysts for different timing. Their special feature is the use of a unified methodical approach which takes into account the qualitative composition of populations and the background conditions of their habitat.

    Assessment of the effect of absence of spawning on the fish-farming and biological characteristics of Siberian sturgeon Acipenser baerii (Brandt, 1869) offspring (2022)
    Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) | Moscow (Russia)
    Details
    Publication Date: 2022-12-20
    Description: The article presents the results of studies on the effect of spawning season absence of female Siberian sturgeon of the Lena population on the fish-biological characteristics of the experimental group, as well as the grown-up juveniles in the conditions of industrial farms. The offspring of experimental females that underwent the resorption process, despite the lowest weight of embryos at hatching, maintained a high growth rate throughout the entire rearing period, comparable with juveniles of control groups.
    Description: Представлены результаты исследований о влиянии пропуска нерестового сезона у самок сибирского осетра ленской популяции на рыбоводно-биологические характеристики экспериментальной группы, а также подрощенной молоди в условиях индустриальных хозяйств. Потомство опытной самки, прошедшей процесс резорбции, несмотря на самую низкую массу эмбрионов при вылуплении, на всём протяжении выращивания сохраняло высокий темп роста, сравнимый с молодью контрольных групп.

    Assessment of the influence of temperature on the formation of the Eastern and Western Kamchatka pink salmon population in different life periods (2022)
    Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) | Moscow (Russia)
    Details
    Publication Date: 2022-12-20
    Description: The article presents the results of a comparative analysis of some databases describing SST (sea surface temperature) along the coast of Western Kamchatka with data from domestic weather stations carried out in the villages of Bolsheretsk, Icha, Sobolevo and Ozernovsky. These weather stations monitored air temperature and, in some years, water temperature in adjacent coastal areas. Databases ("10-days-SST", "MGDSST", "HIMSST") that adequately describe the actual curves of water temperature in the coastal area and air temperature in the area of concentration of the main spawning water basins and watercourses (ECMWF V5) have been identified. The selected databases were used to develop long-term series of temperature characteristics in the Kamchatka mainland and some areas of the Bering and Okhotsk Seas used by Western and Northeastern Kamchatka pink salmon at different stages of its life cycle.
    Description: Проведен сравнительный анализ некоторых баз данных (БД) описывающих SST (температуру поверхности воды) вдоль побережья западной Камчатки с данными отечественных метеостанций поселков Большерецк, Ича, Соболево и Озерновский, осуществлявших мониторинг температуры воздуха и в отдельные годы температуры воды в прилегающих участках прибрежья. Выявлены БД («10-days-SST», «MGDSST», «HIMSST») адекватно описывающие фактический ход температуры воды в прибрежье и температуры воздуха в районе концентрации основных нерестовых водоемов и водотоков (ECMWF V5). Выбранные базы данных использовались для построения продолжительных рядов температурных характеристик в материковой части Камчатки и некоторых районов Берингова и Охотского морей, используемых горбушей западного и северо-восточного побережий Камчатки на разных этапах своего жизненного цикла.
