Population and distribution of beavers Castor fiber and Castor canadensis in Eurasia
(Peer reviewed; Journal article, 2020)1. A century ago, overhunting had reduced Eurasian beaver Castor fiber populations to c. 1200 animals in scattered refugia from France to Mongolia. Reintroductions and natural spread have since restored the species to large ... -
Scent-sniffing dogs can discriminate between native Eurasian and invasive North American beavers
(Peer reviewed; Journal article, 2019)The invasion of a species can cause population reduction or extinction of a similar native species due to replacement competition. There is a potential risk that the native Eurasian beaver (Castor fiber) may eventually be ... -
A stochastic event-based approach for flood estimation in catchments with mixed rainfall and snowmelt flood regimes
(Peer reviewed; Journal article, 2019)The estimation of extreme floods is associated with high uncertainty, in part due to the limited length of streamflow records. Traditionally, statistical flood frequency analysis and an event-based model (PQRUT) using a ... -
Island biogeography theory explains the genetic diversity of a fragmented rock ptarmigan (Lagopus muta) population
(Peer reviewed; Journal article, 2019)The island biogeography theory is one of the major theories in ecology, and its applicability to natural systems is well documented. The core model of the theory, the equilibrium model of island biogeography, predicts that ... -
Phylogeography, genetic diversity, and connectivity of brown bear populations in Central Asia
(Peer reviewed; Journal article, 2019)Knowledge of genetic diversity and population structure is critical for conservation and management planning at the population level within a species’ range. Many brown bear populations in Central Asia are small and ... -
Water body type and group size affect the flight initiation distance of European waterbirds
(Peer reviewed; Journal article, 2019)Human encroachment on nature grows constantly, increasing human-wildlife interactions. Flight initiation distance (FID, the distance at which animals flee from an approaching threat) is often used to measure antipredator ... -
Formalin treatments before eyeing and hand-picking of Arctic charr (Salvelinus alpinus) eggs; re-evaluating the timing of antifungal treatments
(Peer reviewed; Journal article, 2019)Arctic charr (Salvelinus alpinus) eggs in hatcheries are treated for fungal infections using formalin before, and hand-picking during the eyed stage. The relative effectiveness of these two treatments was evaluated using ... -
Glacial history and palaeo-environmental change of southern Taimyr Peninsula, Arctic Russia, during the Middle and Late Pleistocene
(Peer reviewed; Journal article, 2019)We here reconstruct a glacial and climate history of arctic NW Siberia for the last ~600,000 years, based on the stratigraphy and chronology of 35 studied river sections on the southern Taimyr Peninsula. From this stratigraphic ... -
Data set on sedimentology, palaeoecology and chronology of Middle to Late Pleistocene deposits on the Taimyr Peninsula, Arctic Russia
(Peer reviewed; Journal article, 2019)This Data in Brief paper contains data (including images) from Quaternary sedimentary successions investigated along the Bol'shaya Balakhnya River and the Luktakh–Upper Taimyra–Logata river system on southern Taimyr ... -
Strutseving (Matteúccia struthiópteris (L.) Tod.) - en vanlig bregneart som kan bli en gourmetgrønnsak også i Norge. Litteraturoversikt
(Bioforsk TEMA;, Research report, 2007)Det finnes et landbruksprodukt som er sterkt etterspurt i deler av USA og Canada, men som synes å være nesten ukjent i Europa. Produktet har blitt beskrevet som ”en smakfull og næringsrik grønnsak”. Råvaretilgangen og ... -
Mikronisert Solaritt (Ca-silikat) for bruk i vassdragskalking
(NIVA-rapport;, Research report, 2019)To typer av mikronisert solaritt (Ca2SiO4); Sol.2 og Sol.3, ble undersøkt for egnethet til bruk i vassdragskalking. Solarittene ble sammenliknet med de tradisjonelle kalkingsmidlene CaCO3 og NaOH i labforsøk for å studere ... -
Total circulating cell-free DNA as a prognostic biomarker in metastatic colorectal cancer before first-line oxaliplatin-based chemotherapy
(Journal article; Peer reviewed, 2019)Background Metastatic colorectal cancer (mCRC) is a heterogeneous disease where prognosis is dependent both on tumor biology and host factors. Total circulating cell-free DNA (cfDNA) has shown to harbor prognostic ... -
Coupling of VAMPERS within iLOVECLIM: experiments during the LGM and Last Deglaciation
(Journal article; Peer reviewed, 2019)The VAMPERS (Vrije Universiteit Amsterdam Permafrost Snow Model) has been coupled within iLOVECLIM, an earth system model. This advancement allows the thermal coupling between permafrost and climate to be examined from a ... -
Cervids as sentinel-species for tick-borne encephalitis virus in Norway - A serological study
(Journal article; Peer reviewed, 2019)Tick‐borne encephalitis virus (TBEV) is the causative agent of tick‐borne encephalitis (TBE). TBEV is one of the most important neurological pathogens transmitted by tick bites in Europe. The objectives of this study were ... -
Agreement between reconstructed and modeled boreal precipitation of the Last Interglacial
(Journal article; Peer reviewed, 2019)The last extended time period when climate may have been warmer than today was during the Last Interglacial (LIG; ca. 129 to 120 thousand years ago). However, a global view of LIG precipitation is lacking. Here, seven new ... -
Distribution of allele frequencies for genes associated with physical activity and/or physical capacity in a homogenous Norwegian cohort- a cross-sectional study
(Journal article; Peer reviewed, 2020)Background There are large individual differences in physical activity (PA) behavior as well as trainability of physical capacity. Heritability studies have shown that genes may have as much impact on exercise participation ... -
Experimental infection of lambs with tick-borne encephalitis virus and co-infection with Anaplasma phagocytophilum.
(Journal article; Peer reviewed, 2019)Tick-borne encephalitis virus (TBEV) is a zoonotic pathogen which may cause tick-borne encephalitis (TBE) in humans and animals. More than 10,000 cases of TBE are reported annually in Europe and Asia. However, the knowledge ... -
Brood‐stock management and early hatchery rearing of Arctic charr (Salvelinus alpinus (Linnaeus))
(Journal article; Peer reviewed, 2019)Arctic charr (Salvelinus alpinus (Linnaeus)) is a stenothermic cold‐water fish, which has been cultured in Northern Europe and North America since the 1980s. The industry has remained relatively small with an annual ... -
Modelling the vegetation response to the 8.2 ka BP cooling event in Europe and Northern Africa
(Journal article; Peer reviewed, 2019)The 8.2 ka bp cooling event is assumed to be the most clearly marked abrupt climate event in the Holocene at northern mid‐ to high latitudes. In this study, we simulate the vegetation responses to the 8.2 ka bp climate ... -
Distribution of Neoehrlichia mikurensis in Ixodes ricinus ticks along the coast of Norway: The western seaboard is a low-prevalence region
(Journal article; Peer reviewed, 2019)Neoehrlichia mikurensis is a tick‐borne pathogen widespread among ticks and rodents in Europe and Asia. A previous study on Ixodes ricinus ticks in Norway suggested that N. mikurensis was scarce or absent on the south‐west ...
