  • Optimal body size and energy expenditure during winter: Why are voles smaller in declining populations? 
    Ergon, Torbjørn; Speakman, John R.; Scantlebury, Michael; Cavanagh, Rachel; Lambin, Xavier (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2004)

  • A poly approach to ploidy : polyploid evolution and taxonomic implications 
    Jørgensen, Marte Holten (Doctoral thesis / Doktoravhandling, 2011)
    Polyploidy, i.e., the duplication of entire nuclear genomes, has shaped the evolution of major lineages of eukaryotes, and is particularly important in the Plant Kingdom. Molecular analyses suggest that the genomes of most ...
