    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 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 ...

    Differentiation at the MHCIIα and Cath2 Loci in Sympatric Salvelinus alpinus Resource Morphs in Lake Thingvallavatn 
    Kapralova, Kalina; Guðbrandsson, Jóhannes; Reynisdottir, Sigrun; Santos, Cristina B.; Baltanás, Vanessa C; Maier, Valerie H. untranslated; Snorrason, Sigurður S.; Palsson, Arnar (Public Library of Science (PLoS), 2013-07-24)
    Northern freshwater fish may be suitable for the genetic dissection of ecological traits because they invaded new habitats after the last ice age (∼10.000 years ago). Arctic charr (Salvelinus alpinus) colonizing streams and lakes in Iceland gave rise ...

    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 ...

    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 ...
