  • Scully, Sean (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05-31)
    The protein and amino acid metabolism of thermophilic bacteria has been a neglected aspect of their physiology despite its biotechnological potential. Under anaerobic conditions, the metabolism of many proteogenic amino acids requires the presence of ...
  • Ong, Joyce J. L.; Meekan, Mark G.; Hsu, Hua Hsun; Fanning, L. Paul; Campana, Steven (Frontiers Media SA, 2020-04-06)
    Conservation and management strategies for endangered and threatened species require accurate estimates of demographic parameters such as age and growth. The whale shark, Rhincodon typus, is the largest fish in the world and is highly valued in the ...
  • Barry, Tom (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-01-28)
    The geo-political importance of the Arctic is growing while at the same time the onset of climate change has resulted in increasing environmental and social pressures both on Arctic states and the governance architecture through which Arctic issues ...

    Landslide mapping and analysis are essential aspects of hazard and risk analysis. Landslides can block rivers and create landslide-dammed lakes, which pose a significant risk for downstream areas. In this research, we used an object-based image analysis ...
  • Palsson, Arnar; Gibson, Greg (Genetics Society of America, 2004-07-01)
    As part of an effort to dissect quantitative trait locus effects to the nucleotide level, association was assessed between 238 single-nucleotide and 20 indel polymorphisms spread over 11 kb of the Drosophila melanogaster Egfr locus and nine relative ...

    As the world’s social-environmental problems increasingly extend across boundaries, both disciplinary and political, there is a growing need for interdisciplinarity, not only in research per se, but also in doctoral education. We present the common ...

    BACKGROUND: Azithromycin (Azm) is a macrolide recognized for its disease-modifying effects and reduction in exacerbation of chronic airway diseases. It is not clear whether the beneficial effects of Azm are due to its anti-microbial activity or other ...
  • 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 ...
  • Schmid, Magdalena Maria E; Zori, Davide; Erlendsson, Egill; Batt, Cathy; Damiata, Brian N; Byock, Jesse (SAGE Publications, 2017-06-22)
    Icelandic settlement (Landnám) period farmsteads offer opportunities to explore the nature and timing of anthropogenic activities and environmental impacts of the first Holocene farming communities. We employ Bayesian statistical modelling of archaeological, ...
  • Yi, Zhiqian (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2018-11-30)
    Diatoms are a major group of algae in the phytoplankton community and can be found in waters worldwide wherever sufficient nutrients and lights are present. Marine diatoms, such as Phaeodactylum tricornutum, can accumulate high levels of lipids and ...
  • Macdonald, Jed; Logemann, Kai; Krainski, Elias T.; Sigurðsson, Þorsteinn; Beale, Colin M.; Huse, Geir; Hjøllo, Solfrid S.; Marteinsdottir, Gudrun (Wiley, 2017-09-13)
    Social learning can be fundamental to cohesive group living, and schooling fishes have proven ideal test subjects for recent work in this field. For many species, both demographic factors, and inter‐ (and intra‐) generational information exchange are ...
  • Cook, David; Davidsdottir, Brynhildur; Malinauskaite, Laura (Elsevier BV, 2020-12)
    This paper presents the first study in the academic literature to explore the various stages in the formation of geothermal ES and their interactions between the biosphere and anthroposphere. This is achieved through the development of the first ES ...
  • Denechaud, Côme; Smoliński, Szymon; Geffen, Audrey J.; Godiksen, Jane A.; Campana, Steven (Wiley, 2020-08-20)
    Marine ecosystems, particularly in high-latitude regions such as the Arctic, have been significantly affected by human activities and contributions to climate change. Evaluating how fish populations responded to past changes in their environment is ...
