  • 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, ...
  • Guðbrandsson, Jóhannes; Pashay Ahi, Ehsan; Franzdottir, Sigridur Rut; Kapralova, Kalina; Kristjansson, Bjarni K.; Steinhäuser, Sophie S.; Maier, Valerie H.; Johannesson, Isak M.; Snorrason, Sigurdur 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 ...
  • 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 ...
  • Guðbrandsson, Jóhannes; Franzdottir, Sigridur Rut; Kristjansson, Bjarni K.; Pashay Ahi, Ehsan; Maier, Valerie H.; Kapralova, Kalina; Snorrason, Sigurdur 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 ...
  • 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 ...
  • Beck, Samantha V.; Carvalho, Gary R.; Barlow, Axel; Rüber, Lukas; Hui Tan, Heok; Nugroho, Estu; Wowor, Daisy; Mohd Nor, Siti Azizah; Herder, Fabian; Muchlisin, Zainal A.; de Bruyn, Mark (Public Library of Science (PLoS), 2017-07-25)
    The complex climatic and geological history of Southeast Asia has shaped this region’s high biodiversity. In particular, sea level fluctuations associated with repeated glacial cycles during the Pleistocene both facilitated, and limited, connectivity ...
  • 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 ...
  • Bjarnason, Thoroddur; Edvardsson, Ingi Runar; Arnarson, Ingólfur; Skúlason, Skúli; Baldursdóttir, Kolbrún Ósk (Háskóli Íslands, 2016-12-16)
    Mikill munur er á menntunarstigi þjóðarinnar eftir landshlutum. Árið 2011 höfðu þannig 38% íbúa höfuðborgarsvæðisins á aldrinum 25–64 ára lokið háskólaprófi en 21–23% í flestum öðrum landshlutum. Þessi munur skýrist að hluta af takmörkuðu framboði ...
  • 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; Kristjansson, Bjarni K.; Leblanc, Camille A‐L.; 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 ...
