  • 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 ...
  • 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 ...
  • Wutke, Saskia; Benecke, Norbert; Sandoval-Castellanos, Edson; Döhle, Hans-Jürgen; Friederich, Susanne; Gonzalez, Javier; Hofreiter, Michael; Lõugas, Lembi; Magnell, Ola; Morales-Muniz, Arturo; Orlando, Ludovic; Reissmann, Monika; Ruttkay, Matej; Trinks, Alexandra; Ludwig, Arne; Palsdottir, Albina Hulda; Hallsson, Jon (Springer Nature, 2016-12-07)
    Horses have been valued for their diversity of coat colour since prehistoric times; this is especially the case since their domestication in the Caspian steppe in ~3,500 BC. Although we can assume that human preferences were not constant, we have only ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • 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 ...
