(Agricultural University of Iceland, 2025-05-30)High-latitude plant growth processes involve a range of physiological and biochemical mechanisms that allow plants to progress during relatively short growing seasons from unmature to fully developed organisms capable of reproducing. During the past ... -
(2025-01)Abstract: The Icelandic horse is celebrated for its unique gaits and versatility as a riding horse, yet the genetic basis of these characteristics is not fully understood. Its diverse gait range, the availability of extensive phenotypic records, and ...
-
(2024-12)Rapid environmental changes in the Arctic tundra are driving shifts in herbivore populations, distribution, and phenology, affecting the structure of herbivore community. These changes will have consequences to ecosystem structure and function through ...
-
(2024-03-14)As the global climate is changing dramatically, Northern communities are facing a multitude of challenges including changing weather patterns, sea level rise and invasive species. To cope with the recent climatic changes - many of which present great ...
-
(2022)Rangelands are currently facing increasing threats from climate change, overgrazing and land conversion and rangeland degradation is a growing concern worldwide. The ability of degraded rangelands to provide the natural resources needed to sustain ...
-
(Agricultural University of Iceland, 2020)Thirty-seven dairy cows of the Icelandic breed were used in a change-over design experiment. The aim was to analyse the effects of moderate addition of high-palmitic acid (C16:0) fat supplement to a grass silage-based diet. There were three experimental ...
-
(2020-06)Every summer, free-roaming sheep graze large parts of Icelandic rangeland ecosystems, even though some of these rangeland areas are estimated to be in a severely eroded or even collapsed ecological condition. Improved rangeland management and ecosystem ...
-
(2020-06)Climate warming has had significant effects on insect herbivores in Iceland, including an increased rate of establishment of new species as well as changes in outbreak patterns and distribution of insect herbivores. Many of these herbivores live on ...
-
(Copernicus GmbH, 2019-12-10)Drained organic forest soils in boreal and temperate climate zones are believed to be significant sources of the greenhouse gases (GHGs) carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), but the annual fluxes are still highly uncertain. ...
-
(Elsevier BV, 2019-11)In April and May 2010 the Icelandic volcano Eyjafjallajökull experienced an explosive eruption that led to substantial ashfall across the central-southern parts of the island. The resulting ash deposits covered Eyjafjallajökull, Mýrdalsjökull and parts ...
-
(Elsevier BV, 2019-11)V-dust (v-dust) is a highly variable source of natural particles in the atmosphere, and during the period of high volcanic activity it can provide a large surface for heterogeneous interactions with other atmospheric compounds. Icelandic v-dust was ...
-
(Copernicus GmbH, 2019-02-14)The Nordic Centre of Excellence CRAICC (Cryosphere–Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011–2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research ...
-
(Springer Science and Business Media LLC, 2019-11-06)High Latitude Dust (HLD) contributes 5% to the global dust budget, but HLD measurements are sparse. Dust observations from Iceland provide dust aerosol distributions during the Arctic winter for the first time, profiling dust storms as well as clean ...
-
(Agricultural University of Iceland, 2019)Predicted genetic progress in production traits was compared using three different models for genetic evaluation of Icelandic dairy cows. The models were: a random regression (RR) test-day model, model using lactation yields until day 305 from calving ...
-
(Agricultural University of Iceland, 2019)The only native tree species in Iceland forming woodland is the mountain birch. Since human settlement in the 9th century AD, natural birch woodlands have decreased from around 28% to 1.5% of the terrestrial area. In this paper we estimated and compared ...
-
(Agricultural University of Iceland, 2019)The incidence of horticultural pests in combination with increased frequency of extreme weather events, like summer drought, can compromise crop production in Nordic agricultural systems during the already short summer growing season. In particular, ...
-
(Agricultural University of Iceland, 2019)A total of 480,495 test-day yield records of 33,052 cows were used to estimate the genetic parameters for daily milk yield (MY), fat yield (FY), protein yield (PY) and somatic cell score (SCS) of Icelandic dairy cows in the first three lactations with ...
-
(Wiley, 2019-03-06)Molecular serum markers that can identify early reversible osteoarthritis (OA) in horses are lacking. Objectives: We studied serum concentrations of a novel cartilage oligomeric matrix protein (COMP) neo-epitope in horses subjected to short-term exercise ...
-
(Frontiers Media SA, 2019-01-09)High latitude dust is an important contributor to the global dust cycle, which affects the radiative balance of the atmosphere. The frequency and severity of dust events are driven by variables such as wind speed, precipitation, temperature, surface ...
