• From clear lakes to murky waters – tracing the functional response of high-latitude lake communities to concurrent ‘greening’ and ‘browning’ 

      Hayden, B.; Harrod, C.; Thomas, S.M.; Eloranta, Antti; Myllykangas, J.‐P.; Siwertsson, Anna; Præbel, Kim; Knudsen, Rune; Amundsen, Per-Arne; Kahilainen, Kimmo Kalevi (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-21)
      Climate change and the intensification of land use practices are causing widespread eutrophication of subarctic lakes. The implications of this rapid change for lake ecosystem function remain poorly understood. To assess how freshwater communities respond to such profound changes in their habitat and resource availability, we conducted a space‐for‐time analysis of food‐web structure in 30 lakes ...
    • Polyunsaturated fatty acids in freshwater fishes increase with total lipids irrespective of feeding sources and trophic position 

      Kainz, M.J.; Hager, H.H.; Rasconi, S.; Kahilainen, Kimmo K.; Amundsen, Per-Arne; Hayden, B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-03)
      Trophic transfer and retention of dietary compounds are vital for somatic development, reproduction, and survival of aquatic consumers. In this field study, stable carbon and nitrogen isotopes, and fatty acids (FA) contents in invertebrates and fishes of pre-alpine Lake Lunz, Austria, were used to (1) identify the resource use and trophic level of Arctic charr (Salvelinus alpinus), pike (Esox lucius), ...
