    • The nestling diet of Svalbard snow buntings identified by DNA metabarcoding 

      Stolz, Christian (Master thesis; Mastergradsoppgave, 2019-05-15)
      Tundra arthropods have considerable ecological importance as a food source for several bird species that are reproducing in the Arctic. The actual arthropod taxa comprising the chick diet are however rarely known, complicating assessments of ecological interactions. In this study, I identified the nestling diet of Svalbard snow bunting (Plectrophenax nivalis) for the first time. Faecal samples of ...

    • Predator–prey interactions in the Arctic: DNA metabarcoding reveals that nestling diet of snow buntings reflects arthropod seasonality 

      Stolz, Christian; Varpe, Øystein; Ims, Rolf Anker; Sandercock, Brett Kevin; Stokke, Bård Gunnar; Fossøy, Frode (Journal article; Tidsskriftartikkel, 2023-07-06)
      Tundra arthropods are of considerable ecological importance as a seasonal food source for many arctic-breeding birds. Dietary composition and food preferences are rarely known, complicating assessments of ecological interactions in a changing environment. In our field study, we investigated the nestling diet of snow buntings (Plectrophenax nivalis (L., 1758)) breeding in Svalbard. We collected fecal ...
