    • Arctic greening and bird nest predation risk across tundra ecotones 

      Ims, Rolf Anker; Henden, John-André; Strømeng, Marita Anti; Thingnes, Anders Voss; Garmo, Mari; Jepsen, Jane Uhd (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-01)
      Alarming global-scale declines of bird numbers are occurring under the changing climate, and species belonging to alpine and Arctic tundra are particularly affected. Increased nest predation appears to be involved4, but the mechanisms linking predation to climate change remain to be shown. Here we test the prediction from food web theory that increased primary productivity (greening of tundra) in a ...

    • An assessment of survey methods to estimate spring density of two ptarmigan species in arctic Norway 

      Delaye, Aurélie; Strømeng, Marita Anti (Master thesis; Mastergradsoppgave, 2016-05-17)
      Both Willow ptarmigan (Lagopus lagopus) and Rock ptarmigan (Lagopus muta) are important game species in mainland Norway, but were recently added to the Norwegian Red List due to long-term population declines. Yet the knowledge about the population dynamics and the underlying drivers of both species is limited, especially for L. muta. Developing robust methods for long-term monitoring of population ...
