    Bacterial diversity in Icelandic cold spring sources and in relation to the groundwater amphipod Crangonyx islandicus 
    Gudmundsdottir, Ragnhildur; Kreiling, Agnes-Katharina; Kristjánsson, Bjarni Kristófer; Marteinsson, Viggó; Palsson, Snaebjorn (Public Library of Science (PLoS), 2019-10-02)
    Crangonyx islandicus is a groundwater amphipod endemic to Iceland, considered to have survived the Ice Ages in subglacial refugia. Currently the species is found in spring sources in lava fields along the tectonic plate boundary of the country. The ...

    Chironomidae fauna of springs in Iceland – assessing the ecological relevance behind Tuxen’s spring classification 
    Kreiling, Agnes-Katharina; Olafsson, Jon S.; Palsson, Snaebjorn; Kristjansson, Bjarni K. (PAGEPress Publications, 2018-05-31)
    In 1937, S.L. Tuxen studied the animal community of hot springs in Iceland, and classified springs according to their relative temperature into cold, tepid, and hot. Eighty years after Tuxen’s study, we revisited some of the hot springs in Skagafjörður, ...

    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 ...

    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 ...

    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 ...
