    Biotic interactions mediate patterns of herbivore diversity in the Arctic 
    Barrio, Isabel C; Bueno, C. Guillermo; Gartzia, M; Soininen, E.M.; Christie, K.S.; Speed, J.D.M.; Ravolainen, V.T.; Forbes, B.C.; Gauthier, G.; Horstkotte, T.; Hoset, K.S.; Hoye, T.T.; Jónsdóttir, Ingibjörg Svala; Lévesque, E.; Mörsdorf, M.A.; Olofsson, J.; Wookey, P.A.; Hik, D.S. (John Wiley & Sons Ltd, 2016)
    Aim. Understanding the forces shaping biodiversity patterns, particularly for groups of organisms with key functional roles, will help predict ecosystem responses to environmental changes. Our aim was to evaluate the relative role of different drivers ...

    Evidence of effects of herbivory on Arctic vegetation: a systematic map protocol 
    Soininen, E.M.; Barrio, Isabel C; Jepsen, J.U.; Ehrich, D.; Ravolainen, V.T.; Speed, J.D.M. (Springer Nature, 2018-09-27)
    Along with climate change, herbivory is considered a main driver of ecosystem change in terrestrial Arctic environments. Understanding how herbivory influences the resilience of Arctic ecosystems to ongoing environmental changes is essential to inform ...

    Foraging behaviour and plant selection in a herd of Icelandic goats 
    Ævarsdóttir, Hrafnhildur; Thorhallsdottir, Anna Gudrun; Sigurjónsdottir, Hrefna (Agricultural University of Iceland, 2016-06)
    The Icelandic goat is an indigenous breed, descendant of goats brought to Iceland by Nordic and Celtic settlers in the 9th century (Adalsteinsson 1981). The population is estimated to have been below 1000 individuals for centuries and critically ...

    Geothermal ecosystems as natural climate change experiments: The ForHot research site in Iceland as a case study 
    Sigurdsson, Bjarni D.; Leblans, Niki; Dauwe, Steven; Guðmundsdóttir, Elín; Gundersen, Per; G. Gunnarsdóttir, Gunnhildur Eva; Holmstrup, Martin; Ilieva-Makulec, Krassimira; Kätterer, Thomas; Marteinsdóttir, Bryndís; Maljanen, Marja; Oddsdóttir, Edda Sigurdís; Ostonen, Ivika; Penuelas, Josep; Poeplau, Christopher; Richter, Andreas; Sigurðsson, Páll; van Bodegom, Peter; Wallander, Håkan; Weedon, James; Janssens, Ivan (Agricultural University of Iceland, 2016)
    This article describes how natural geothermal soil temperature gradients in Iceland have been used to study terrestrial ecosystem responses to soil warming. The experimental approach was evaluated at three study sites in southern Iceland; one grassland ...

    The Icelandic volcanic aeolian environment: Processes and impacts — A review 
    Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Olafsson, Haraldur (International Society for Aeolian Research, 2016-02-15)
    Iceland has the largest area of volcaniclastic sandy desert on Earth or 22,000 km2. The sand has been mostly produced by glacio-fluvial processes, leaving behind fine-grained unstable sediments which are later re-distributed by repeated aeolian events. ...

    Impact of dust deposition on the albedo of Vatnajökull ice cap, Iceland 
    Wittmann, Monika; Groot Zwaaftink, Christine; Steffensen Schmidt, Louise; Guðmundsson, Sverrir; Pálsson, Finnur; Arnalds, Olafur; Björnsson, Helgi; Thorsteinsson, Throstur; Stohl, Andreas (Copernicus GmbH, 2017-03-23)
    Deposition of small amounts of airborne dust on glaciers causes positive radiative forcing and enhanced melting due to the reduction of surface albedo. To study the effects of dust deposition on the mass balance of Brúarjökull, an outlet glacier of the ...

    The sheep in wolf‘s clothing? Recognizing threats for land degradation in Iceland using state-and-transition models 
    Barrio, Isabel C; Hik, D.S.; Þórrsson, Jóhann; Svavarsdóttir, Kristín; Marteinsdóttir, Bryndís; Jónsdóttir, Ingibjörg Svala (John Wiley & Sons, Ltd., 2018)
    Land degradation and extensive soil erosion are serious environmental concerns in Iceland. Natural processes associated with a harsh climate and frequent volcanic activity have shaped Icelandic landscapes. However, following human settlement and the ...

    The Spatial Variation of Dust Particulate Matter Concentrations during Two Icelandic Dust Storms in 2015 
    Olafsson, Haraldur; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Magnúsdóttir, Agnes Ösp (MDPI AG, 2016-06-03)
    Particulate matter mass concentrations and size fractions of PM1, PM2.5, PM4, PM10, and PM15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. Images from a camera network were used to estimate the ...

    Temporal and spatial variability of Icelandic dust emissions and atmospheric transport 
    Groot Zwaaftink, Christine; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Eckhardt, Sabine; Prospero, Joseph M.; Stohl, Andreas (Copernicus GmbH, 2017-09-14)
    Icelandic dust sources are known to be highly active, yet there exist few model simulations of Icelandic dust that could be used to assess its impacts on the environment. We here present estimates of dust emission and transport in Iceland over 27 years ...
