    Acclimation of Fine Root Systems to Soil Warming: Comparison of an Experimental Setup and a Natural Soil Temperature Gradient 
    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 ...

    Carbon sequestration and community composition of ectomycorrhizal fungi across a geothermal warming gradient in an Icelandic spruce forest 
    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 ...

    Evaluating the process of ecological restoration 
    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 ...

    Reviews and syntheses: Greenhouse gas exchange data from drained organic forest soils: A review of current approaches and recommendations for future research 
    Jauhiainen, Jyrki; Alm, Jukka; Bjarnadóttir, Brynhildur; Callesen, Ingeborg; Christiansen, Jesper R.; Clarke, Nicholas; Dalsgaard, Lise; He, Hongxing; Jordan, Sabine; Kazanavičiūtė, Vaiva; Klemedtsson, Leif; Lauren, Ari; Lazdins, Andis; Lehtonen, Aleksi; Lohila, Annalea; Lupikis, Ainars; Mander, Ülo; Minkkinen, Kari; Kasimir, Åsa; Olsson, Mats; Ojanen, Paavo; Óskarsson, Hlynur; Sigurdsson, Bjarni D.; Søgaard, Gunnhild; Soosaar, Kaido; Vesterdal, Lars; Laiho, Raija (Copernicus GmbH, 2019-12-10)
    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. ...

    Soil nematode communities on Surtsey, 50 years after the formation of the volcanic island 
    Ilieva-Makulec, Krassimira; Bjarnadóttir, Brynhildur; Sigurdsson, Bjarni D. (Agricultural University of Iceland, 2015)
    Soil nematodes are a key group that can both influence and reflect changes in the soil ecosystem. We investigated the generic composition, abundance and community structure of soil nematodes in two contrasting vegetation successional seres now found ...
