  • Parts, Kaarin; Tedersoo, Leho; Schindlbacher, Andreas; Sigurdsson, Bjarni D.; Leblans, Niki; Oddsdóttir, Edda Sigurdís; Borken, Werner; Ostonen, Ivika (Springer Science and Business Media LLC, 2018-07-09)
    Global warming is predicted to impact high-latitude and high-altitude forests severely, jeopardizing their overall functioning and carbon storage, both of which depend on the warming response of tree fine root systems. This paper investigates the effect ...
  • Rosenstock, Nicholas; Ellström, Magnus; Oddsdóttir, Edda Sigurdís; Sigurdsson, Bjarni D.; Wallander, Håkan (Elsevier BV, 2019-08)
    Soil warming (0–5.5 °C above controls) effects on ectomycorrhizal growth, carbon sequestration and community composition were examined in a Picea sitchensis forest spanning a geothermal gradient in Iceland. Fungal communities were assayed with sand-filled ...
  • Alkalaj, Jovana; Hrafnsdottir, Thora; Ingimarsson, Finnur; Smith, Robin J; Kreiling, Agnes-Katharina; Mischke, Steffen (Oxford University Press (OUP), 2019-04-25)
    Ostracods in Icelandic freshwaters have seldom been researched, with the most comprehensive record from the 1930s. There is a need to update our knowledge of the distribution of ostracods in Iceland as they are an important link in these ecosystems as ...
  • Nyamweya, Chrispine (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-01)
    Lake Victoria is of immense ecological and socio-economic significance for the riparian communities. However, the lake is faced with human induced pressures such as overfishing, introduction of alien species, increased eutrophication and climate change ...
  • Silva, Teresa Sofia Giesta da (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2018-12-14)
    Krill are an important component of the Icelandic marine ecosystem. Given their important ecological niche, as conveyors of biological production between phytoplankton and higher trophic levels, fluctuations in krill abundance can have large impacts ...
  • Nilsson, Christer; Aradottir, Ása L.; Hagen, Dagmar; Halldórsson, Guðmundur; Høegh, Kenneth; Mitchell, Ruth J.; Raulund-Rasmussen, Karsten; Svavarsdóttir, Kristín; Tolvanen, Anne; Wilson, Scott D. (Resilience Alliance, Inc., 2016)
    We developed a conceptual framework for evaluating the process of ecological restoration and applied it to 10 examples of restoration projects in the northern hemisphere. We identified three major phases, planning, implementation, and monitoring, in ...
  • Oostdijk, Maartje (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-04-29)
    The management of marine resources pose a difficult commons problem as monitoring behavior is difficult and benefit flows from the resources are uncertain. Implementing individual transferable quota (ITQ) is a management regime in which quasi-property ...
  • Beck, Samantha V. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-01-30)
    Intraspecific variation in egg size and its effects on offspring fitness is well documented in fishes. Yet whether or not differential per propagule maternal investment (egg size) can influence phenotypic diversification is little understood. Arctic ...
  • Boulton, Andrew J.; Ekebom, Jan; Gislason, Gisli Mar (Wiley-Blackwell, 2016-09)
    Over the last two decades, there has been increasing public and political recognition of society's dependency upon natural habitat complexity and ecological processes to sustain provision of crucial ecosystem services, ranging from supplying potable ...
  • Strøm, John Fredrik; Rikardsen, Audun Håvard; Campana, Steven; Righton, David; Carr, Jonathan; Aarestrup, Kim; Stokesbury, Michael J. W.; Gargan, Patrick; Javierre, Pablo Caballero; Thorstad, Eva Bonsak (Springer Science and Business Media LLC, 2019-05-27)
    Predation and mortality are often difcult to estimate in the ocean, which hampers the management and conservation of marine fshes. We used data from pop-up satellite archival tags to investigate the ocean predation and mortality of adult Atlantic ...

    Drained organic forest soils in boreal and temperate climate zones are believed to be significant sources of the greenhouse gases (GHGs) carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), but the annual fluxes are still highly uncertain. ...
  • von Leesen, Gotje; Ninnemann, Ulysses S.; Campana, Steven (Oxford University Press (OUP), 2020-02-14)
    Increasing water temperatures are predicted around the globe, with high amplitudes of warming in Subarctic and Arctic regions where Atlantic cod (Gadus morhua) populations currently flourish. We reconstructed oxygen isotope and temperature chronologies ...
  • Demars, Benoît O. L.; Manson, J. R.; Ólafsson, Jón S.; Gislason, Gisli Mar; Friberg, N. (EDP Sciences, 2011)
    Stream ecosystem metabolism plays a critical role in planetary biogeochemical cycling. Stream benthic habitat complexity and the available surface area for microbes relative to the free-flowing water volume are thought to be important determinants ...
  • O'Gorman, Eoin J.; Ólafsson, Ólafur P.; Demars, Benoît O. L.; Friberg, Nikolai; Guðbergsson, Guðni; Hannesdóttir, Elísabet R.; Jackson, Michelle C.; Johansson, Liselotte S.; McLaughlin, Órla B.; Ólafsson, Jón S.; Woodward, Guy; Gislason, Gisli Mar (Wiley-Blackwell, 2016-03)
    Global warming is widely predicted to reduce the biomass production of top predators, or even result in species loss.Several exceptions to this expectation have been identified, however, and it is vital that we understand the underlyingmechanisms if we ...
