    The developmental transcriptome of contrasting Arctic charr (Salvelinus alpinus) morphs 
    Guðbrandsson, Jóhannes; Pashay Ahi, Ehsan; Franzdottir, Sigridur Rut; Kapralova, Kalina; Kristjansson, Bjarni K.; Steinhäuser, Sophie S.; Maier, Valerie H.; Johannesson, Isak M.; Snorrason, Sigurður S.; Jonsson, Zophonias O.; Palsson, Arnar (F1000 Research, Ltd., 2016-12-02)
    Species and populations with parallel evolution of specific traits can help illuminate how predictable adaptations and divergence are at the molecular and developmental level. Following the last glacial period, dwarfism and specialized bottom feeding ...

    Differential gene expression during early development in recently evolved and sympatric Arctic charr morphs 
    Guðbrandsson, Jóhannes; Franzdottir, Sigridur Rut; Kristjansson, Bjarni K.; Pashay Ahi, Ehsan; Maier, Valerie H.; Kapralova, Kalina; Snorrason, Sigurður S.; Jónsson, Zophonías Oddur; Palsson, Arnar (PeerJ, 2018-02-07)
    Phenotypic differences between closely related taxa or populations can arise through genetic variation or be environmentally induced, leading to altered transcription of genes during development. Comparative developmental studies of closely related ...

    Ecological correlates of diel activity in Arctic charr Salvelinus alpinus 
    Larranaga, Nicolas (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2016-11)
    Diel activity, the partitioning of time between periods of activity and rest, gives insights into how organisms compete for resources in time. Some species show plasticity in the rate and timing of their activity, which enables to study associations ...

    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 ...

    Life Cycle Assessment of Icelandic Arctic Char Fed Three Different Feed Types 
    Smárason, Birgir Örn; Ögmundarson, Ólafur; Arnason, Jon; Bjornsdottir, Rannveig; Davidsdottir, Brynhildur (Central Fisheries Research Institute, Trabzon, Turkey, 2017)
    This study utilized Life Cycle Assessment (LCA) to quantify the environmental impacts of 1 kg of live-weight Arctic char, cultivated in an Icelandic land-based aquaculture farm. The functional unit included assessments of three different feed types; ...

    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 ...
