    • Effect of tower base painting on willow ptarmigan collision rates with wind turbines 

      Stokke, Bård Gunnar; Nygård, Torgeir; Falkdalen, Ulla; Pedersen, Hans Christian; May, Roelof Frans (Peer reviewed; Journal article, 2020)
      1. Birds colliding with turbine rotor blades is a well-known negative consequence of wind-power plants. However, there has been far less attention to the risk of birds colliding with the turbine towers, and how to mitigate ...

    • Estimating spatially variable and density-dependent survival using open-population spatial capture–recapturemodels 

      Milleret, Cyril Pierre; Dey, Soumen; Dupont, Pierre; Brøseth, Henrik; Turek, Daniel; Bischof, Richard (Peer reviewed; Journal article, 2022)
      Open-population spatial capture–recapture (OPSCR) models use the spatialinformation contained in individual detections collected over multiple consec-utive occasions to estimate not only occasion-specific density, but ...

    • Impacts of a weir and power station on downstream migrating Atlantic salmon smolts in a German river 

      Havn, Torgeir Børresen; Thorstad, Eva Bonsak; Borcherding, Jost; Heermann, Lisa; Teichert, Maxim A. K.; Ingendahl, Detlev; Tambets, Meelis; Sæther, Stein Are; Økland, Finn (Peer reviewed; Journal article, 2020)
      Weirs are barriers built across rivers for a wide range of other purposes than hydropower production. Like hydropower installations, weirs can negatively impact fish migrations. Downstream migration and mortality of Atlantic ...

    • Influences of migration phenology on survival are size-dependent in juvenile Atlantic salmon (Salmo salar) 

      Jonsson, Bror; Jonsson, Marius; Jonsson, Nina (Journal article; Peer reviewed, 2017)
      Long-distance migratory species can reduce mortality risks by synchronizing the migration event and create confusion by swamping predators with high densities. To reduce confusion, predators are known to primarily select ...

    • Raptor Interactions with Wind Energy: Case Studies from Around the World 

      Watson, Richard T.; Kolar, Patrick S; Ferrer, Miguel; Nygård, Torgeir; Johnston, Naira; Hunt, W; Smit-Robinson, Hanneline A; Farmer, Christopher J; Huso, Manuela; Katzner, Todd E (Peer reviewed; Journal article, 2018)
      The global potential for wind power generation is vast, and the number of installations is increasing rapidly. We review case studies from around the world of the effects on raptors of wind-energy development. Collision ...

    • Sociodemographic factors modulate the spatial response of brown bears to vacancies created by hunting 

      Frank, Shane C.; Leclerc, Martin; Pelletier, Fanie; Rosell, Frank Narve; Swenson, Jon; Bischof, Richard; Kindberg, Jonas; Eiken, Hans Geir; Hagen, Snorre; Zedrosser, Andreas (Journal article; Peer reviewed, 2017)
      1. There is a growing recognition of the importance of indirect effects from hunting on wildlife populations, e.g., social and behavioral changes due to harvest, which occur after the initial offtake. Nonetheless, little ...
