Meta-Analysis of 1,200 Transcriptomic Profiles Identifies a Prognostic Model for Pancreatic Ductal Adenocarcinoma
(Peer reviewed; Journal article, 2019)PURPOSE: With a dismal 8% median 5-year overall survival, pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy. Only 10% to 20% of patients are eligible for surgery, and more than 50% of these patients ... -
Do bank voles (Myodes glareolus) trapped in live and lethal traps show differences in tick burden?
(Peer reviewed; Journal article, 2020)In studies assessing tick abundance, the use of live traps to capture and euthanize rodent hosts is a commonly used method to determine their burden. However, captive animals can experience debilitating or fatal capture ... -
The distribution limit of the common tick, Ixodes ricinus, and some associated pathogens in north-western Europe
(Peer reviewed; Journal article, 2020)In north-western Europe, the common tick, Ixodes ricinus, is widely established, its distribution appears to be increasing and the spread of tick-borne diseases is of increasing concern. The project ‘Flått i Nord’ (Ticks ... -
Reindeer carcasses provide foraging habitat for insectivorous birds of the alpine tundra
(Peer reviewed; Journal article, 2019)On August of 2016, almost an entire herd (n = 323) of wild tundra reindeer (Rangifer tarandus) was killed by lightning on Hardangervidda in southern Norway. While conducting fieldwork for another study in 2017, we ... -
Water chemistry, zooplankton and benthos in small lakes within the distribution area of the rare European pool frog Pelophylax lessonae (Camerano) in Norway
(Peer reviewed; Journal article, 2020)In June 2018, water chemistry, benthos and zooplankton were investigated in 7 small lakes/ponds within the key area of the European pool frog Pelophylax lessonae (Camerano) in Norway. The geographic distribution of the ... -
Landscape genetics of northern crested newt Triturus cristatus populations in a contrasting natural and human-impacted boreal forest
(Peer reviewed; Journal article, 2020)Among vertebrates, amphibians currently have the highest proportion of threatened species worldwide, mainly through loss of habitat, leading to increased population isolation. Smaller amphibian populations may lose more ... -
Factors determining parasite abundance in European perch, Perca fluviatilis, European whitefish, Coregonus lavaretus, and Arctic charr, Salvelinus alpinus, in an oligotrophic lake, southern Norway
(Peer reviewed; Journal article, 2020)Temporal and spatial variations in macroparasite status were investigated in European perch, Perca fluviatilis, European whitefish, Coregonus lavaretus, and Arctic charr, Salvelinus alpinus in Lake Norsjø (Southern Norway), ... -
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 ... -
