    • Environmental variation as a driver of predator-prey interactions 

      Tablado, Zulimo; Fauchald, Per; Mabille, Geraldine; Stien, Audun; Tveraa, Torkild (Peer reviewed; Journal article, 2014)
      Animals often face the trade-off of optimizing foraging while limiting predation. In variable and seasonal environments the availability of resources changes spatially and temporally, forcing animals to adapt their spatial ...

    • Foraging tactics in dynamic sea-ice habitats affect individual state in a long-ranging seabird
