  • Davíðsdóttir, Brynja; Gunnarsson, Tomas Gretar; Halldórsson, Guðmundur; Sigurdsson, Bjarni D. (Agricultural University of Iceland, 2016)
    Degradation of ecosystems and introductions of invasive species pose a threat to global biodiversity. Ecosystem restoration and revegetation actions are important for amending habitat loss and for the protection of species of plants and animals. Iceland ...
  • Willow, Jonathan (Agricultural University of Iceland, 2017)
    Bumblebees (Bombus spp.) are pollinators of especially high conservation interest. They have behaviours (pollen-gathering, buzz pollination), morphological structures (branched body hairs well-adapted for retaining pollen), and endothermic capabilities, ...
  • Šiaudinis, Gintaras; Liaudanskiene, Inga; Slepetiene, Alvyra (Agricultural University of Iceland, 2017)
    An experiment with three perennial energy crops – common mugwort (Artemisia vulgaris L.), cup plant (Silphium perfoliatum L.) and virginia mallow (Sida hermaphrodita Rusby) has been carried out in Lithuania (55°43′N, 21°28′E) in order to evaluate the ...
  • Granquist, Sandra; Hauksson, Erlingur (Agricultural University of Iceland, 2016)
    The effect of harbour seal predation on salmonids has been frequently debated, although interactions between these species have never been thoroughly investigated in Icelandic waters prior to this study. We investigated the diet of harbour seals in a ...
  • Maljanen, Marja; Liimatainen, Maarit; Sigurdsson, Bjarni D. (Landbúnaðarháskóli Íslands, 2015-02)
    Past volcanic eruptions in Iceland have sometimes led to long-distance distribution of fine volcanic tephra (volcanic ash). Evidence for volcanic ash from, for example, the ca. 4250 BP eruption in Hekla (H4) and the 1783-1784 AD Laki eruption in southern ...
  • 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 ...
  • Hejcman, M.; Hejcmanová, P.; Pavlů, V.; Thorhallsdottir, Anna Gudrun (Wiley-Blackwell, 2016-04-27)
    Woody species played, and in many Nordic regions still play, a very important role in livestock feeding. However, forage quality (contents of macroelements and fibre fractions) of the leaves of common woody species is often inadequate. The aim of our ...
  • Ævarsdóttir, Hrafnhildur; Þórhallsdottir, Anna Gudrún; 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 ...
  • 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 S.; 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 ...
  • Mandáková, Terezie; Thorbjörnsson, Hjörtur; Pisupati, Rahul; Reichardt, Ilka; Lysak, Martin A; Anamthawat-Jónsson, Kesara (Agricultural University of Iceland, 2017)
    In this paper, we report the first discovery of Arabidopsis thaliana in Iceland. In May 2015, the plants were located growing on warm geothermal soil around the hot spring Deildartunguhver in Reykholt, West Iceland. Flower buds and leaves were collected ...
  • Gudmundsson, Jon; Brink, Sigmundur H.; Arnalds, Olafur; Gisladottir, Fanney O.; Oskarsson, Hlynur (Society of Wetland Scientists, 2016-06-09)
    Iceland has inland wetland areas with soils exhibiting both Andosol and Histosol properties which are uncommon elsewhere on Earth. They are generally fertile, with higher bird-nest densities than in similar wetlands in the neighboring countries, with ...
  • 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. ...
  • 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 ...

    Climate change is stronger at high than at temperate and tropical latitudes. The natural geothermal conditions in southern Iceland provide an opportunity to study the impact of warming on plants, because of the geothermal bedrock channels that induce ...
  • Lenstra, J.A.; Tigchelaar, J.; Biebach, I.; Kantanen, J.; Nielsen, V.H.; Pompanon, F.; Naderi, S.; Rezaei, H.R.; Saether, N.; Ertugrul, O.; Grossen, C.; Camenisch, G.; Vos-Loohuis, M.; van Straten, M.; de Poel, E.A.; Windig, J.; Oldenbroek, K.; Hallsson, Jon (Wiley-Blackwell, 2016-06)
    In the last decades, several endangered breeds of livestock species have been re-established effectively. However, the successful revival of the Dutch and Danish Landrace goats involved crossing with exotic breeds and the ancestry of the current ...
