  1. 6. Safeguarding a Safeguard: Assessing the Status of Global Ex-Situ Crop Conservation and the Svalbard Global Seed Vault’s Role in its Protection

    Magister-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Christopher Keegan; [2022]
    Nyckelord :Svalbard Global Seed Vault; Genebanks; Genetic Resources; Genetic Erosion; Passport Data Completeness; Agriculture and Food Sciences;

    Sammanfattning : The Svalbard Seed Vault serves as a backup against accidental loss of genetic crop diversity within the existing global conservation system. Addressing this objective, this thesis repeats the 2013 assessment of the Seed Vault’s completeness relative to the global conservation system as performed by Westengen et al (2013, 1). LÄS MER

  3. 7. Estimating the effective population size of Swedish native cattle : understanding the demographic trajectories of indigenous Swedish cattle breeds

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Dolapo Adepoju; [2022]
    Nyckelord :Swedish native cattle; effective population size; genetic drift; cattle demographic trajectories; native cattle conservation;

    Sammanfattning : The indigenous cattle populations are on the decline globally with the continuous improvement of genetic gains in commercial breeds. Due to their unique adaptive features to the local ecosystem, traditional cattle breeds are pools of valuable genetic resources that could help combat the impact of climate change in the near future.

  4. 8. Genbanksmaterial av ärt och åkerböna : en inventering av tillgängliga växtgenetiska resurser för förädling för svenska förhållanden

    Kandidat-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Linnea Svensson; [2022]
    Nyckelord :Pisum sativum; Vicia faba; växtgenetiska resurser; genbanker; växtförädling; svenska förhållanden; inhemskt producerat protein;

    Sammanfattning : För att kunna trygga livsmedelsförsörjningen i världen krävs grödor som är anpassade för odling i olika klimatregioner. Genom växtförädling kan nya sorter av grödor, som är bättre anpassade, tas fram. LÄS MER

  5. 9. Active Learning for Solving Expensive Optimization Problems

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Siwei Fu; [2022]
    Nyckelord :;

    Sammanfattning : Many practical engineering and computer science problems can be translated into a global otimization problem where the task is to find the best (optimal) vector 𝒙𝒙∗ that gives the smallest possible function value 𝑓𝑓 = 𝑓𝑓(𝒙𝒙∗) for some function 𝑓𝑓() of interest. Often the function 𝑓𝑓() is expensive in the sense that it cannot be easily evaluated computationally or experimentally in terms of time and/or resources required. LÄS MER

  7. 10. Controls of the partitioning of nitrate between DNRA and denitrifiers

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Frida Lindvall; [2022]
    Nyckelord :DNRA; denitrification; microcosm; experiment; arable soil;

    Sammanfattning : In arable soils, the importance of denitrification, a respiratory process where nitrate (NO3-) is stepwisely reduced to nitrogen gas and nitrous oxide (N2O) is well established. More recently has dissimilatory nitrate reduction to ammonium (DNRA) gained interest as its importance in agricultural soils might have been largely overlooked. LÄS MER
