    • 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 ...
    • Spatial consistency in drivers of population dynamics of a declining migratory bird
