    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 ...
  • 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 ...

    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 ...
  • 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 ...
  • Eydal, Matthías; Skirnisson, Karl (Agricultural University of Iceland, 2016)
    The aim of this paper is to report cases of the intestinal parasitic nematode Strongyloides stercoralis in dogs in Iceland. The nematode was diagnosed in 20 (0.6%) of imported dogs in quaratine in Iceland during 1989-2016. Household dogs: The first ...
  • 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. ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
