    Comparative analysis of fish-farming and biological indicators of male Siberian sturgeon in the second stage of sexual maturity (2022)
    Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) | Moscow (Russia)
    Details
    Publication Date: 2022-12-20
    Description: The article presents the comparative results of two-year experimental works on obtaining sexual products from male Siberian sturgeons in conditions of a straight-flow basin industrial enterprise with annual total amount of 5500 degree-days are presented. The fish-farming, biological and morphological characteristics of the producers, their comparative indicators of the quality of sexual products, histological characteristics of the initial state of the gonads are given. It has been noted that the body weight and sperm movement time in Siberian sturgeon increase with age by 41.1 and 12.0 %, more ejaculate is produced by 21.8 %, the visual quality of sperm improves by 27.0 %, but the relative fecundity decreases by 11.6 %.
    Description: Представлены сравнительные результаты двухлетних экспериментальных работ по получению половых продуктов от самцов сибирского осетра в условиях прямоточного бассейнового индустриального предприятия с годовой суммой тепла 5500 градусо-дней. Приведена рыбоводно-биологическая и морфологическая характеристики производителей, их сравнительные показатели качества половых продуктов, гистологическая картина исходного состояния гонад. Отмечено, что с возрастом у сибирского осетра увеличивается масса тела и время движения сперматозоидов на 41,1 и 12,0 %, продуцируется больше эякулята на 21,8 %, улучшается визуальное качество спермы на 27,0 %, но уменьшается относительная плодовитость на 11,6 %.

    Structural change in coal regions as a process of economic and social-ecological transition : lessons learnt from structural change processes in Germany (2022)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-04-08
    Description: Effective policies to mitigate climate change need to be accompanied by a socially just transition. Based on experiences of past and ongoing transition policies in coal regions in Europe and with indications to the specificity of framework conditions and challenges and to the potential effectiveness and transferability of approaches, this paper presents lessons learnt which can be inspirational for similar transitions in other coal regions and for transitions in other sectors.

    Suitability and success factors of offsets post-2020 (2022)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-08-15
    Description: Offsetting enables countries and companies to meet part of their climate change mitigation obligations by using mitigation outcomes generated elsewhere - in lieu of own emission reductions. This report explores the future role of offset approaches and how they could be successfully integrated into a post-2020 climate regime by focusing both the supply and demand side. For this purpose, the report develops a conceptual approach that derives a normative vision of what should be considered a successful offset use in a top-down manner to then link this vision to specific factors on the ground in sectors and jurisdictions where offsets will be generated and used. It explores how these factors influence the successful operationalisation of the offset approach and how they can inform its design. In addition, the report also explores six conceptual design aspects to providing recommendations on how to take these factors into account during the design of the offset approach. Based on these findings, the authors derive overarching policy recommendations on the integration of offsets into carbon pricing schemes.

    Assessment of intraspecific composition of regional groups of juvenile chum salmon (Oncorhynchus keta) in the Sea of Okhotsk in the autumn of 2019 (2022)
    Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) | Moscow (Russia)
    Details
    Publication Date: 2022-12-20
    Description: The population and genetic structure of chum salmon in the main reproduction regions of the Russian Far East is presented based on the variability of eight microsatellite loci (Ssa20.19, One101, Oke3, Oki1b, Oki23, Ogo2G, Oke11, Ots102). Four main regional groups have been identified for the purposes of genetic identification. The accuracy of the estimates obtained is calculated for each of the four groups. The authors present the results of genetic identification according to the autumn trawl survey in the Sea of Okhotsk in 2019.
    Description: Представлена популяционно-генетическая структура кеты по основным регионам воспроизводства Дальнего Востока России на основе изменчивости восьми микросателлитных локусов (Ssa20.19, One101, Oke3, Oki1b, Oki23, Ogo2G, Oke11, Ots102). В целях генетической идентификации определены четыре основные региональные группы, для каждой из которых рассчитана точность получаемых оценок. Приведены результаты генетической идентификации по данным осенней траловой съемки в Охотском море в 2019 г.

    Analysis of the historical structural change in the German lignite mining area of Lusatia (case study) (2022)
    Dessau-Roßlau : Umweltbundesamt
    Details
    Publication Date: 2022-04-08
    Description: This case study examined the structural change in Lusatia caused by the system change from a centrally planned economy to a market economy in the period 1990-2015. It analysed the structural change process and the structural policies implemented as a reaction to this process with the objective to make this knowledge available for future structural change processes in other (coal) regions by deploying various qualitative and quantitative methods of empirical social and economic research. A discourse analysis helped to recognise who supported which structural policy approaches and why - and thus gives indications of the possible relevance of experiences for other regions.
