  • 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 ...
  • Katrínardóttir, Borgný; Alves, Jose; Sigurjónsdóttir, Hrefna; Hersteinsson, Páll; Gunnarsson, Tomas Gretar (Public Library of Science (PLoS), 2015-07-10)
    Distinct preference of species for habitats is most often driven by long term differences in demographic rates between habitats. Estimating variation in those rates is key for developing successful conservation strategies. Stochastic events can interact ...

    Trypsins from Atlantic cod (Gadus morhua), consisting of several isoenzymes, are highly active cold-adapted serine proteases. These trypsins are isolated for biomedical use in an eco-friendly manner from underutilized seafood by-products. Our group has ...
  • Ludwig, Michael Z; Palsson, Arnar; Alekseeva, Elena; Bergman, Casey M; Nathan, Janaki; Kreitman, Martin (Public Library of Science (PLoS), 2005-03-15)
    Lack of knowledge about how regulatory regions evolve in relation to their structure–function may limit the utility of comparative sequence analysis in deciphering cis-regulatory sequences. To address this we applied reverse genetics to carry out a ...
  • Gargallo-Garriga, Albert; Ayala-Roque, Marta; Sardans, Jordi; Bartrons, Mireia; Granda, Victor; Sigurdsson, Bjarni D.; Leblans, Niki; Oravec, Michal; Urban, Otmar; Janssens, Ivan; Penuelas, Josep (MDPI AG, 2017-08-23)
    Climate change is stronger at high than at temperate and tropical latitudes. The natural geothermal conditions in southern Iceland provide an opportunity to study the impact of warming on plants, because of the geothermal bedrock channels that induce ...
  • Wesolowska, Natalia; Reynisdóttir, Sigrún; Ludwig, Michael Z.; Kreitman, Martin; Palsson, Arnar (Public Library of Science (PLoS), 2014-05-01)
    Changes in regulatory DNA contribute to phenotypic differences within and between taxa. Comparative studies show that many transcription factor binding sites (TFBS) are conserved between species whereas functional studies reveal that some mutations ...
  • Hjörleifsson, Jens G; Ásgeirsson, Bjarni (American Chemical Society (ACS), 2017-09-07)
    The effect of ionic strength on enzyme activity and stability varies considerably between enzymes. Ionic strength is known to affect the catalytic activity of some alkaline phosphatases (APs), such as Escherichia coli AP, but how ions affect APs is ...
  • Clark, Chase M.; Costa, Maria Sofia; Conley, Erin; Li, Emma; Sanchez, Laura M.; Murphy, Brian T. (MyJove Corporation, 2019-05-15)
    In order to visualize the relationship between bacterial phylogeny and specialized metabolite production of bacterial colonies growing on nutrient agar, we developed IDBac-a low-cost and high-throughput matrix-assisted laser desorption/ionization ...
