    Bacterial communities of lichens and mosses, and nitrogen fixation in a warming climate 
    Klarenberg, Ingeborg J. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-10)
    Climate warming in sub-Arctic regions leads to shifts in plant communities and retreating glaciers. Mosses and lichens contribute to important ecosystem processes in these environments, including nitrogen fixation via their microbiome. The first objective ...

    Beyond Chloride Brines: Variable Metabolomic Responses in the Anaerobic Organism Yersinia intermedia MASE-LG-1 to NaCl and MgSO4 at Identical Water Activity 
    Schwendner, Petra; Bohmeier, Maria; Rettberg, Petra; Beblo-Vranesevic, Kristina; Gaboyer, Frédéric; Moissl-Eichinger, Christine; Perras, Alexandra K.; Vannier, Pauline; Marteinsson, Viggó; Garcia-Descalzo, Laura; Gómez, Felipe; Malki, Moustafa; Amils, Ricardo; Westall, Frances; Riedo, Andreas; Monaghan, Euan P.; Ehrenfreund, Pascale; Cabezas, Patricia; Walter, Nicolas; Cockell, Charles (Frontiers Media SA, 2018-02-27)
    Growth in sodium chloride (NaCl) is known to induce stress in non-halophilic microorganisms leading to effects on the microbial metabolism and cell structure. Microorganisms have evolved a number of adaptations, both structural and metabolic, to ...

    Comparative Analysis of Microbial Diversity Across Temperature Gradients in Hot Springs From Yellowstone and Iceland 
    Podar, Peter T.; Yang, Zamin; Björnsdóttir, Snædís; Podar, Mircea (Frontiers Media SA, 2020-07-14)
    Geothermal hot springs are a natural setting to study microbial adaptation to a wide range of temperatures reaching up to boiling. Temperature gradients lead to distinct microbial communities that inhabit their optimum niches. We sampled three alkaline, ...

    Exploration of the Microbial Communities within the Basaltic Subsurface of the Volcanic Island Surtsey in Iceland 
    Bergsten, Pauline (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2022-09)
    Surtsey is a volcanic island located on the south-east offshore extension of the Icelandic rift zone. It was formed during successive eruptions from the seafloor in 1963-1967 and has been officially protected and studied ever since. It represents ...

    Host-microbe symbiosis in the marine sponge Halichondria panicea 
    Knobloch, Stephen (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05)
    Sponges (phylum Porifera) are considered one of the oldest extant lineages of the animal kingdom. Their close association with microorganism makes them suitable for studying early animal-microbe symbiosis and expanding our understanding of host-microbe ...

    Lack of correlation of desiccation and radiation tolerance in microorganisms from diverse extreme environments tested under anoxic conditions 
    Beblo-Vranesevic, Kristina; Bohmeier, Maria; Perras, Alexandra K; Schwendner, Petra; Rabbow, Elke; Moissl-Eichinger, Christine; Cockell, Charles S; Vannier, Pauline; Marteinsson, Viggó; Monaghan, Euan P; Ehrenfreund, Pascale; Garcia-Descalzo, Laura; Gómez, Felipe; Malki, Moustafa; Amils, Ricardo; Gaboyer, Frédéric; Westall, Frances; Cabezas, Patricia; Walter, Nicolas; Rettberg, Petra (Oxford University Press (OUP), 2018-02-21)
    Four facultative anaerobic and two obligate anaerobic bacteria were isolated from extreme environments (deep subsurface halite mine, sulfidic anoxic spring, mineral-rich river) in the frame MASE (Mars Analogues for Space Exploration) project. The ...

    Microbes and the groundwater amphipod Crangonyx islandicus in spring sources in Iceland 
    Gudmundsdottir, Ragnhildur (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)
    Crangonyx islandicus is a groundwater amphipod endemic to Iceland. Genetic analysis suggests that the species has been diverging in Iceland for at least 4.8 Myrs indicating it has survived in a subglacial refugia as Iceland was repeatedly covered by ...

    The responses of an anaerobic microorganism, Yersinia intermedia MASE-LG-1 to individual and combined simulated Martian stresses 
    Beblo-Vranesevic, Kristina; Bohmeier, Maria; Perras, Alexandra K.; Schwendner, Petra; Rabbow, Elke; Moissl-Eichinger, Christine; Cockell, Charles S.; Pukall, Rüdiger; Vannier, Pauline; Marteinsson, Viggó; Monaghan, Euan P.; Ehrenfreund, Pascale; Garcia-Descalzo, Laura; Gómez, Felipe; Malki, Moustafa; Amils, Ricardo; Gaboyer, Frédéric; Westall, Frances; Cabezas, Patricia; Walter, Nicolas; Rettberg, Petra (Public Library of Science (PLoS), 2017-10-25)
    The limits of life of aerobic microorganisms are well understood, but the responses of anaerobic microorganisms to individual and combined extreme stressors are less well known. Motivated by an interest in understanding the survivability of anaerobic ...
