  1. 21. Effects of landscape context on populations of bumblebees

    Författare :Anna Persson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apoidea; Bombus; Campanula; agriculture; land-use intensity; complexity; garden; grassland; field border; MFC; pollination; Factor Analysis;

    Sammanfattning : To investigate recent declines in bumblebee populations, I carried out landscape analyses, made field studies of bumblebees, flowering plants and pollination in an agricultural region in southernmost Sweden. Studies were carried out in landscapes of contrasting agricultural intensity and land-cover configuration; "simple" landscapes highly dominated by large crop fields, and "complex" with mixed farming, grasslands and smaller fields.

  3. 22. Computational Modelling of Gene Regulation in Cancer : Coding the noncoding genome

    Författare :Husen Muhammad Umer; Jan Komorowski; Claes Wadelius; Jan Korbel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Regulatory elements; gene regulation; cancer; motif; integrative database; software solutions for cancer data; Bioinformatics; Bioinformatik;

    Sammanfattning : Technological advancements have enabled quantification of processes within and around us. The information stored within our body converts into petabytes of data. Processing and learning from such data requires comprehensive computational programs and software systems. LÄS MER

  4. 23. Cross-scale monitoring, landscape trajectories, and feedback in forest management : Examples from southern and middle boreal ecosystems in Sweden

    Författare :Sofia Eriksson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physical geography; Naturgeografi; Terrestrial ecology; Terrestisk ekologi;

    Sammanfattning : To manage for sustainability in a complex and changing world requires understanding of the coupled human-environmental system. The two case studies in this licentiate thesis are linked by what we can learn from past and current management in the form of feedback and how it can be incorporated into practical forest management within the boreal region.
