      Migration is a common trait among many animals allowing the exploitation of spatiotemporally variable resources. It often implies high energetic costs to cover large distances, for example between breeding and wintering ...
    • North Atlantic winter cyclones starve seabirds

      Each winter, the North Atlantic Ocean is the stage for numerous cyclones, the most severe ones leading to seabird mass-mortality events called ‘‘winter wrecks.’’ During these, thousands of emaciated seabird carcasses are ...
    • Offshore oil rigs – a breeding refuge for Norwegian Black-legged Kittiwakes Rissa tridactyla? 

      Christensen-Dalsgaard, Signe; Langset, Magdalene; Anker-Nilssen, Tycho (Peer reviewed; Journal article, 2020)
      In recent decades, the population of Black-legged Kittiwake Rissa tridactyla has declined substantially in most parts of the North Atlantic. Concurrently, there has been an increased urbanisation of the species, with ...
