      Global warming is a nonlinear process, and temperature may increase in a stepwise manner. Periods of abrupt warming can trigger persistent changes in the state of ecosystems, also called regime shifts. The responses of organisms to abrupt warming and associated regime shifts can be unlike responses to periods of slow or moderate change. Understanding of nonlinearity in the biological responses to ...
    • Climate change, non-indigenous species and shipping: assessing the risk of species introduction to a high-Arctic archipelago 

      Ware, Christopher; Berge, Jørgen; Sundet, Jan Henry; Kirkpatrick, JB; Coutts, A.D.M.; Jelmert, Anders; Olsen, SM; Floerl, O; Wisz, Mary S.; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Aim: Anticipated changes in the global ocean climate will affect the vulnerability of marine ecosystems to the negative effects of non-indigenous species (NIS). In the Arctic, there is a need to better characterize present and future marine biological introduction patterns and processes. We use a vector-based assessment to estimate changes in the vulnerability of a high-Arctic archipelago to marine ...

    • The dependence of long-distance migration to North Norway on environmental conditions in the wintering area and en route 

      Barrett, Robert T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      The onset of bird migration may be under partial endogenous control whereas the timing of movement is flexible with weather and conditions faced by the moving birds being the ultimate cause of variability of arrival dates. This study shows that the early arrival dates of two of three long-distance passerine spring migrants (Willow Warblers Phylloscopus trochilus and Chiffchaffs P. collybita) in North ...
    • Det er for seint å snyte seg når nesa er borte - Om betydningen av å utvikle lokale kompetanseutviklingstrategier i distriktssamfunn. 

      Danielsen, Ådne; Grepperud, Gunnar (Chronicle; Kronikk, 2013)
      Kronikken tar for seg hvordan kommuner i distriktene kan møte kompetansebehov i egen organisasjon og lokalsamfunn. Det handler om å utvikle strategier som gjør at man satser på å utvikle kompetansen hos egne innbyggere for på den måten å sikre seg tilgang på kompetent arbeidskraft.
    • DNA barcoding a taxonomically complex hemiparasitic genus reveals deep divergence between ploidy levels but lack of species-level resolution 

      Wang, Xumei; Gusarova, Galina; Ruhsam, Markus; de Vere, Natasha; Metherell, Chris; Hollingsworth, Peter M.; Twyford, Alex D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-24)
      DNA barcoding is emerging as a useful tool not only for species identification but also for studying evolutionary and ecological processes. Although plant DNA barcodes do not always provide species-level resolution, the generation of large DNA barcode data sets can provide insights into the mechanisms underlying the generation of species diversity. Here, we study evolutionary processes in taxonomically ...
