    Differential expression of the aryl hydrocarbon receptor pathway associates with craniofacial polymorphism in sympatric Arctic charr 
    Pashay Ahi, Ehsan; Steinhäuser, Sophie S.; Palsson, Arnar; Franzdottir, Sigridur Rut; Snorrason, Sigurður S.; Maier, Valerie H.; Jónsson, Zophonías Oddur (Springer Nature, 2015-09-16)
    Background The developmental basis of craniofacial morphology hinges on interactions of numerous signalling systems. Extensive craniofacial variation in the polymorphic Arctic charr, a member of the salmonid family, from Lake Thingvallavatn (Iceland), ...

    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 ...

    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 ...

    Gene expression in the phenotypically plastic Arctic charr (Salvelinus alpinus): A focus on growth and ossification at early stages of development 
    Beck, Samantha V.; Räsänen, Katja; Ahi, Ehsan P.; Kristjánsson, Bjarni K.; Skúlason, Skúli; Jónsson, Zophonías Oddur; Leblanc, Camille (Wiley, 2018-11-26)
    Gene expression during development shapes the phenotypes of individuals. Although embryonic gene expression can have lasting effects on developmental trajectories, few studies consider the role of maternal effects, such as egg size, on gene expression. ...

    The mitochondrial genome of common whelk Buccinum undatum (Neogastropoda: Buccinidae) 
    Jónsson, Zophonías Oddur; Palsson, Snaebjorn; Westfall, Kristen M.; Magnúsdóttir, Hildur; Goodall, Jake; Örnólfsdóttir, Erla Björk (Informa UK Limited, 2019-01-08)
    The complete mitogenome of Buccinum undatum obtained from transcriptome analysis is presented here. The mitogenome is 15,265 bp in length and comprises 13 protein-coding genes, 2 ribosomal subunit genes, and 22 transfer RNAs. The complete genome was ...

    Shell morphology and color of the subtidal whelk Buccinum undatum exhibit fine-scaled spatial patterns 
    Magnúsdóttir, Hildur; Palsson, Snaebjorn; Westfall, Kristen M.; Jónsson, Zophonías Oddur; Örnólfsdóttir, Erla Björk (Wiley, 2018-04-10)
    Geographical patterns in morphology can be the result of divergence among populations due to neutral or selective changes and/or phenotypic plasticity in response to different environments. Marine gastropods are ideal subjects on which to explore these ...

    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 ...

    A way forward with eco evo devo: an extended theory of resource polymorphism with postglacial fishes as model systems 
    Skúlason, Skúli; Parsons, Kevin J.; Svanbäck, Richard; Räsänen, Katja; Ferguson, Moira M.; Adams, Colin E.; Amundsen, Per‐Arne; Bartels, Pia; Bean, Colin W.; Boughman, Janette W.; Englund, Göran; Guðbrandsson, Jóhannes; Hooker, Oliver E.; Hudson, Alan G.; Kahilainen, Kimmo K.; Knudsen, Rune; Kristjánsson, Bjarni K.; Leblanc, Camille; Jónsson, Zophonías Oddur; Öhlund, Gunnar; Smith, Carl; Snorrason, Sigurður S. (Wiley, 2019-06-19)
    A major goal of evolutionary science is to understand how biological diversity is generated and altered. Despite considerable advances, we still have limited insight into how phenotypic variation arises and is sorted by natural selection. Here we argue ...
