    Diel activity and foraging mode of juvenile Arctic charr in fluctuating water flow 
    Larranaga, Nicolas; Valdimarsson, S.K.; Linnansaari, T.; Steingrímsson, Stefán Óli (Wiley, 2018-02-28)
    Streams fluctuate in water flow because of natural (e.g., rain) and human‐induced events (e.g., hydropeaking). Magnitude, frequency, and predictability of these events can have drastic consequences for fish populations. We studied how rapid modifications ...

    Experimental challenges with Renibacterium salmoninarum in Arctic charr Salvelinus alpinus 
    Guðmundsdóttir, Sigríður; Kristmundsson, Árni; Árnason, Ívar Örn (Inter-Research Science Center, 2017-03-30)
    Arctic charr Salvelinus alpinus L. is an important species in Icelandic aquaculture and the most common wild salmonid in Iceland. A study on the course of infection with the bacterium Renibacterium salmoninarum was conducted using 3 different challenge ...

    Extensive genetic differentiation between recently evolved sympatric Arctic charr morphs 
    Guðbrandsson, Jóhannes; Kapralova, Kalina; Franzdottir, Sigridur Rut; Bergsveinsdóttir, Þóra Margrét; Hafstað, Völundur; Jónsson, Zophonías Oddur; Snorrason, Sigurður S.; Palsson, Arnar (Wiley, 2019-09-12)
    The availability of diverse ecological niches can promote adaptation of trophic specializations and related traits, as has been repeatedly observed in evolutionary radiations of freshwater fish. The role of genetics, environment, and history in ...

    Seasonal variation in the invertebrate community and diet of a top fish predator in a thermally stable spring 
    Kreiling, Agnes-Katharina; O’Gorman, Eoin J.; Pálsson, Snæbjörn; Benhaïm, David; Leblanc, Camille A.; Ólafsson, Jón S.; Kristjánsson, Bjarni K. (Springer Science and Business Media LLC, 2020-09-18)
    Many life-history events in aquatic invertebrates are triggered by seasonal changes in water temperature, but other ecological factors may be important as well. To rule out the confounding effects of changing water temperature, we studied the seasonal ...

    Transcriptional dynamics of a conserved gene expression network associated with craniofacial divergence in Arctic charr 
    Pashay Ahi, Ehsan; Kapralova, Kalina; Palsson, Arnar; Maier, Valerie; Guðbrandsson, Jóhannes; Snorrason, Sigurður S.; Jónsson, Zophonías Oddur; Franzdottir, Sigridur Rut (Springer Nature, 2014)
    Background Understanding the molecular basis of craniofacial variation can provide insights into key developmental mechanisms of adaptive changes and their role in trophic divergence and speciation. Arctic charr (Salvelinus alpinus) is a polymorphic ...
