    Pleistocene climate changes have imposed extreme conditions to intertidal rocky marine communities, forcing many species to significant range shifts in their geographical distributions. Phylogeographic analyses based on ...
  • Moe, Therese Fosholt (Doctoral thesis / Doktoravhandling, 2012)
    Nuisance growth of the aquatic macrophyte Juncus bulbosus has been observed since the 1980s in an increasing number of rivers and lakes in northern Europe. What causes such massive growth is not well understood, however, ...
  • Håland, Julie Tesdal (Master thesis / Hovedoppgave, 2005)
    SAMMENDRAG Celler er kontinuerlig utsatt for påvirkninger som kan skade dets DNA. Dette inkluderer oksidative DNA-skader, som oppstår via normal oksidativ metabolisme, og fra forbindelser i miljøet. Slike DNA-skader kan ...
  • Ergon, Torbjørn; Speakman, John R.; Scantlebury, Michael; Cavanagh, Rachel; Lambin, Xavier (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2004)
    Winter is energetically challenging for small herbivores because of greater energy requirements for thermogenesis at a time when little energy is available. We formulated a model predicting optimal wintering body size, ...
  • Sabarros, Philippe Sunil (Doctoral thesis / Doktoravhandling, 2010)
    The interactions between seabirds and their environment, notably their prey, include complex spatial patterns and mechanisms that span over different scales of processes (e.g. physiology, behaviour, population). To understand ...
  • Veiberg, Vebjørn (Doctoral thesis / Doktoravhandling, 2007)
    Foraging ecology and environmental conditions have represented important driving forces in the evolution of both dental morphology as well as the digestive system. Teeth are essential for digestive processes in ruminants, ...
  • Le Rouzic, Arnaud; Siegel, Paul B; Carlborg, Örjan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2007)
    Background The genetic architecture of a quantitative trait influences the phenotypic response to natural or artificial selection. One of the main objectives of genetic mapping studies is to identify the ...
  • Awas, Tesfaye (Doctoral thesis / Doktoravhandling, 2007)
    The aim of this thesis is to investigate the ecology and ethnobotany of vegetation in Benishangul Gumuz Regional State (BGRS), western Ethiopia. The studies reported in this thesis have confirmed the existence of 1102 ...
  • Grindeland, John Magne (Doctoral thesis / Doktoravhandling, 2008)
    In this thesis I report on several aspects of the reproductive ecology of the short-lived, monocarpic plant Digitalis purpurea L. (Plantaginaceae). Observational field studies are combined with controlled crosses and ...
  • 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 ...
  • Andersen, Øivind; De Rosa, Maria C; Pirolli, Davide; Tooming-Klunderud, Ave; Petersen, Petra E; André, Carl (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)
    Background The two homologous iron-binding lobes of transferrins are thought to have evolved by gene duplication of an ancestral monolobal form, but any conserved synteny between bilobal and monolobal ...
  • Hannelius, Ulf; Salmela, Elina; Lappalainen, Tuuli; Guillot, Gilles; Lindgren, Cecilia M; von Döbeln, Ulrika; Lahermo, Päivi; Kere, Juha (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2008)
    Background Despite several thousands of years of close contacts, there are genetic differences between the neighbouring countries of Finland and Sweden. Within Finland, signs of an east-west duality have ...
