      Finne, Eirik Aasmo; Varpe, Øystein; Durant, Joël; Gabrielsen, Geir W.; Poste, Amanda (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-22)
      Seabirds are important vectors for nutrient transfer across ecosystem boundaries. In this seasonal study, we evaluate the impact of an Arctic colony (Alkhornet, Svalbard) of Black-legged Kittiwakes (Rissa tridactyla) and Brünnich’s Guillemots (Uria lomvia) on stream nutrient concentrations and fuxes, as well as utilization by coastal biota. Water samples from seabird-impacted and control streams ...
