Insights in the regulation of trimetylamine N-oxide production using a comparative biomimetic approach suggest a metabolic switch in hibernating bears
(Peer reviewed; Journal article, 2020)Experimental studies suggest involvement of trimethylamine N-oxide (TMAO) in the aetiology of cardiometabolic diseases and chronic kidney disease (CKD), in part via metabolism of ingested food. Using a comparative biomimetic ... -
Molecular characterisation of TP53 mutated squamous cell carcinomas of the lung to identify putative targets for therapy
(Peer reviewed; Journal article, 2020)Personalised cancer treatment depends on identification of therapeutically relevant biological subgroups of patients for assessing effect of treatment and to discover new therapeutic options. By analyses in heterogeneous ... -
The last glaciation of the Arctic volcanic island Jan Mayen
(Peer reviewed; Journal article, 2020)The volcanic island of Jan Mayen, remotely located in the Norwegian‐Greenland Sea, was covered by a contiguous ice cap during the Late Weichselian. Until now, it has been disputed whether parts of the island south of the ... -
The impact of hydropeaking on juvenile brown trout (Salmo trutta) in a Norwegian regulated river
(Peer reviewed; Journal article, 2020)The Norwegian electrical energy supply system is based on hydropower. The now deregulated energy market has led to increased use of hydropeaking production, leading to greater fluctuations in discharge and water levels ... -
Harvest is associated with the disruption of social and finescale genetic structure among matrilines of a solitary large carnivore
(Peer reviewed; Journal article, 2020)Harvest can disrupt wildlife populations by removing adults with naturally high survival. This can reshape sociospatial structure, genetic composition, fitness, and potentially affect evolution. Genetic tools can detect ... -
Low prevalence of tick-borne encephalitis virus antibodies in Norwegian blood donors
(Peer reviewed; Journal article, 2020)Background: Tick-borne encephalitis (TBE) constitutes a public health concern in Europe. Certain coastal municipalities in southern Norway are considered TBE risk areas and in the last two years, there have been increasing ... -
Fear the reaper: ungulate carcasses may generate an ephemeral landscape of fear for rodents
(Journal article; Peer reviewed, 2020)Animal carcasses provide an ephemeral pulse of nutrients for scavengers that use them. Carcass sites can increase species interactions and/or ephemeral, localized landscapes of fear for prey within the vicinity. Few studies ... -
Beaver (Castor fiber) activity and spatial movement in response to light and weather conditions
(Peer reviewed; Journal article, 2020)Animal behaviour can affect individual fitness and is influenced by exogenous and endogenous factors. Here, we investigated how light (daylight length and moonlight), weather (precipitation and temperature), age, sex and ... -
Atmospheric circulation over Europe during the Younger Dryas
(Peer reviewed; Journal article, 2020)The Younger Dryas (YD) was a period of rapid climate cooling that occurred at the end of the last glaciation. Here, we present the first palaeoglacier-derived reconstruction of YD precipitation across Europe, determined ... -
Tick-borne pathogens in Ixodes ricinus ticks collected from migratory birds in southern Norway
(Peer reviewed; Journal article, 2020)Birds are important hosts for the first life stages of the Ixodes ricinus tick and they can transport their parasites over long distances. The aim of this study was to investigate the prevalence of Borrelia burgdorferi ... -
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 ...
