    • Climate change and the increasing impact of polar bears on bird populations 

      Prop, Jouke; Aars, Jon; Bårdsen, Bård-Jørgen; Hanssen, Sveinn Are; Bech, Claus; Bourgeon, Sophie; Fouw, Jimmy de; Gabrielsen, Geir W.; Lang, Johannes; Noreen, Elin; Oudman, Thomas; Sittler, Benoit; Tombre, Ingunn; Wolters, Eva; Moe, Børge; Stempniewicz, Lech (Peer reviewed; Journal article, 2015)
      The Arctic is becoming warmer at a high rate, and contractions in the extent of sea ice are currently changing the habitats of marine top-predators dependent on ice. Polar bears (Ursus maritimus) depend on sea ice for ...
    • Effects of salmon lice Lepeophtheirus salmonis on wild sea trout Salmo trutta—a literature review 

      Thorstad, Eva Bonsak; Todd, Christopher D.; Uglem, Ingebrigt; Bjørn, Pål Arne; Gargan, Patrick G.; Vollset, Knut Wiik; Halttunen, Elina; Kålås, Steinar; Berg, Marius; Finstad, Bengt (Peer reviewed; Journal article, 2015)
      Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, ...
    • Evaluating interactions of forestconservation policies on avoided deforestation 

      Roballino, Juan; Sandoval, Catalina; Barton, David Nicholas; Chacon, Adriana; Pfaff, Alexander (Journal article; Peer reviewed, 2015)
      We estimate the effects on deforestation that have resulted from policy interactions between parks and payments and between park buffers and payments in Costa Rica between 2000 and 2005. We show that the characteristics ...
    • Governance of ecosystem services: A framework for empirical analysis 

      Primmer, Eeva; Jokinen, Pekka; Blicharska, Malgorzata; Barton, David Nicholas; Bugter, Rob; Potschin, Marion (Journal article; Peer reviewed, 2015)
      Biodiversity conservation policies justified with science and intrinsic value arguments have produced disappointing outcomes, and the need for conservation is now being additionally justified with the concept of ecosystem ...
    • Late snow melt moderates herbivore disturbance of the Arctic tundra 

      Anderson, Helen B.; Speed, James David Mervyn; Madsen, Jesper; Pedersen, Åshild Ønvik; Tombre, Ingunn; van der Wal, René (Journal article; Peer reviewed, 2016)
      Resilience of tundra vegetation to disturbance by herbivores can be low and lead to ecosystem state shifts. Pink-footed geese Anser brachyrhynchus are the most numerous herbivore on Svalbard and disturb vegetation when ...
    • Long-distance plant dispersal to North Atlantic islands:colonization routes and founder effect 

      Alsos, Inger Greve; Ehrich, Dorothee; Eidesen, Pernille Bronken; Solstad, Heidi Merethe; Westergaard, Kristine Bakke; Schonswetter, Peter; Tribsch, Andreas; Birkeland, Siri; Elven, Reidar; Brochmann, Christian (Peer reviewed; Journal article, 2015)
      Long-distance dispersal (LDD) processes influence the founder effect on islands.We use genetic data for 25 Atlantic species and similarities among regional floras to analyse colonization, and test whether the genetic ...
    • Low impact of dry conditions on the CO2 exchange of aNorthern-Norwegian blanket bog. 

      Lund, Magnus; Bjerke, Jarle W.; Drake, Bert G.; Engelsen, Ola; Hansen, Georg Heinrich; Parmentier, Frans-Jan W.; Powell, Thomas; Silvennoinen, Hanna Marika; Sottocornola, Matteo; Tømmervik, Hans; Weldon, Simon Mark; Rasse, Daniel (Peer reviewed; Journal Article, 2015)
      Northern peatlands hold large amounts of organic carbon (C) in their soils and are as such important in a climate change context. Blanket bogs, i.e. nutrient-poor peatlands restricted to maritime climates, may be extra ...
    • Mismatch between fishway operation and timing of fish movements: a risk for cascading effects in partial migration systems 

      van Leeuwen, Casper; Museth, Jon; Sandlund, Odd Terje; Qvenild, Tore; Vøllestad, Leif Asbjørn (Peer reviewed; Journal article, 2016)
      Habitat fragmentation is a growing problem worldwide. Particularly in river systems, numerous dams and weirs hamper the movement of a wide variety of species. With the aim to preserve connectivity for fish, many barriers ...
    • Spatial genetic structure of the abundant and Widespread Peatmoss Sphagnum magellanicum Brid . 

      Kyrkjeeide, Magni Olsen; Hassel, Kristian; Flatberg, Kjell Ivar; Shaw, A. Jonathan; Yousefi, Narjes; Stenøien, Hans K. (PLoS ONE;, Journal article; Peer reviewed, 2016)
    • Statistical and ecological challenges of monitoring parasitic salmon lice infestations in wild salmonid fish stocks 

      Helland, Ingeborg Palm; Uglem, Ingebrigt; Jansen, Peder A; Diserud, Ola Håvard; Bjørn, Pål Arne; Finstad, Bengt (Peer reviewed; Journal article, 2015)
      Ecological monitoring programmes should provide precise data to inform management, but the data quality is often limited by methodological challenges and the need for cost-effective sampling. Parasite infestations are ...
    • There is more to climate than the North Atlantic Oscillation: a new perspective from climate dynamics to explain the variability in population growth rates of a long-lived seabird 

      Mesquita, Michel d. S.; Erikstad, Kjell E; Sandvik, Hanno; Reiertsen, Tone; Barrett, Robert; Anker-Nilssen, Tycho; Hodges, Kevin I.; Bader, Jürgen (Journal article; Peer reviewed, 2015)
