(Copernicus GmbH, 2019-08-06)Afforestation is a strategy to sequester atmospheric carbon in the terrestrial system and to enhance ecosystem services. Iceland's large areas of formerly vegetated and now degraded ecosystems therefore have a high potential to act as carbon sinks. ... -
(Wiley, 2018-02-28)1. Human activities have caused global changes of atmospheric chemistry resulting in increased temperature especially in the colder regions of the northern hemisphere. Since warming of the environment can have drastic effects on terrestrial ecosys-tems ...
-
(Frontiers Media SA, 2018-12-03)Several important ice-free areas (e.g., Seymour Island, Cape Lamb on Vega Island, Terrapin Hill) are located in the Eastern Antarctic Peninsula region. The largest of these ice-free areas can be found on the Ulu Peninsula, James Ross Island, where this ...
-
(Elsevier BV, 2018-07)Managed northern peatlands are an important source of the strong greenhouse gas nitrous oxide (N2O). However, N2O emissions from these managed peatlands display a high spatial variability, and processes governing N2O production and emissions from these ...
-
(Springer Nature, 2018-04-17)Increasing temperatures can accelerate soil organic matter decomposition and release large amounts of CO2 to the atmosphere, potentially inducing positive warming feedbacks. Alterations to the temperature sensitivity and physiological functioning of ...
-
(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 ...
-
(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 ...
-
(Oxford University Press (OUP), 2017-12-08)Global change is expected to affect soil microbial communities through their responsiveness to temperature. It has been proposed that prolonged exposure to elevated temperatures may lead to progressively larger effects on soil microbial community ...
-
(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 ...
-
(IOP Publishing, 2018-12-07)A wide range of research shows that nutrient availability strongly influences terrestrial carbon (C) cycling and shapes ecosystem responses to environmental changes and hence terrestrial feedbacks to climate. Nonetheless, our understanding of nutrient ...
-
(Frontiers Media SA, 2018-04-10)Reproduction is an important trait in sheep breeding as well as in other livestock. However, despite its importance the genetic mechanisms of litter size in domestic sheep (Ovis aries) are still poorly understood. To explore genetic mechanisms underlying ...
-
(Agricultural University of Iceland, 2018)In Iceland, mountain birch dominates indigenous woodlands and scrub communities. For use in inventories of the natural birch population, we derived single parameter aboveground biomass functions from a stratified random sample encompassing the entire ...
-
(Agricultural University of Iceland, 2018)Importing dogs into Iceland was prohibited or restricted from 1909 until 1989, when the ban was lifted and importing dogs and cats permitted, with the proviso of an enforced period of quarantine and the requirement of specific medical treatments and ...
-
(Agricultural University of Iceland, 2018)Maedi-visna virus (MVV) is a lentivirus of sheep causing inflammation in many organs, primarily the lungs and CNS. HIV and SIV also belong to the lentivirus genus of retroviruses. MVV and HIV have many features in common, including genome organization, ...
-
(Agricultural University of Iceland, 2018)Geothermal areas can be local sources of greenhouse gases, both directly from the geothermal system or because of soil warming effects on biological sources. In this study we repeated field measurements methane (CH4) and nitrous oxide (N2O) fluxes along ...
-
(Agricultural University of Iceland, 2018)Afforestation in southwest Iceland is hindered by eroded, infertile soils and salt deposition from strong oceanic winds. A trial plot of 25 provenances of native downy birch collected throughout Iceland was established in 1998 near Keflavik International ...
-
(Frontiers Media SA, 2018-11-05)This work aims to identify the geochemical and mineralogical markers of Icelandic dust and to differentiate it from the dust of local origin deposited at the Ny-Ålesund station. We characterized representative sediment samples from Iceland and Svalbard ...
-
(Springer Nature America, Inc, 2018-11-19)Genetic isolation of breeds may result in a significant loss of diversity and have consequences on health and performance. In this study, we examined the effect of geographic isolation on caprine genetic diversity patterns by genotyping 480 individuals ...
-
(Elsevier BV, 2019-01)Horses are the most common grave goods found in Icelandic Viking Age graves. Horse skeletons have previously been sexed based on pelvis shape and the presence of canine teeth in male horses over 4–5 years of age. Morphological data has shown that all ...
-
(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 ...
