Proteome Analysis of Pancreatic Tumors Implicates Extracellular Matrix in Patient Outcome
(Peer reviewed; Journal article, 2022)Pancreatic cancer remains a disease with unmet clinical needs and inadequate diagnostic, prognostic, and predictive biomarkers. In-depth characterization of the disease proteome is limited. This study thus aims to define ... -
Use of environmental DNA to detect the myxozoan endoparasite Tetracapsuloides bryosalmonae in large Norwegian lakes
(Journal article; Peer reviewed, 2022)Environmental DNA (eDNA) is an increasingly used noninvasive and cost-effective method for species detections in surveillance studies. The myxozoan endoparasite Tetracapsuloides bryosalmonae is the causative agent of ... -
Inkoo and Sindbis viruses in blood sucking insects, and a serological study for Inkoo virus in semi-domesticated Eurasian tundra reindeer in Norway
(Peer reviewed; Journal article, 2022)Background: Mosquito-borne viruses pose a serious threat to humans worldwide. There has been an upsurge in the number of mosquito-borne viruses in Europe, mostly belonging to the families Togaviridae, genus Alphavirus ... -
Retention and loss of PIT tags and surgically implanted devices in the Eurasian beaver
(Peer reviewed; Journal article, 2022)Background: Passive integrated transponder devices (PIT tags) are a valuable tool for individual identification of animals. Similarly, the surgical implantation of transmitters and bio-loggers can provide useful data on ... -
Effect of aerobic exercise intensity on health-related quality of life in severe obesity: a randomized controlled trial
(Peer reviewed; Journal article, 2022)Background: Aerobic exercise is an important part of obesity treatment and may improve health-related quality of life (HRQOL). The objective of this study was to compare the effect of two different exercise programs on ... -
Host in reserve: The role of common shrews (Sorex araneus) as a supplementary source of tick hosts in small mammal communities influenced by rodent population cycles
(Peer reviewed; Journal article, 2022)Rodents often act as important hosts for ticks and as pathogen reservoirs. At north -ern latitudes, rodents often undergo multi- annual population cycles, and the peri -odic absence of certain hosts may inhibit the survival ... -
Size is not everything: differing activity and foraging patterns between the sexes in a monomorphic mammal
(Peer reviewed; Journal article, 2021)Animals balance foraging with other activities, and activity patterns may differ between sexes due to differing physical requirements and reproductive investments. Sex-specific behavioural differences are common in sexually ... -
Climate influence on plant–pollinator interactions in the keystone species Vaccinium myrtillus
(Journal article; Peer reviewed, 2022)Climate change is altering the world's ecosystems through direct effects of climate warming and precipitation changes but also indirectly through changes in biotic interactions. For instance, climate-driven changes in plant ... -
The impact of bio-logging on body weight change of the Eurasian beaver
(Peer reviewed; Journal article, 2021)Bio-logging is a common method to collect ecological data on wild animals, but might also induce stress, reduce body condition, and alter behavior. Eurasian beavers (Castor fiber) are a semi-aquatic and nocturnal species ... -
Spatial and temporal variability in summer diet of gray wolves (Canis lupus) in the Greater Yellowstone Ecosystem
(Peer reviewed; Journal article, 2021)The role of predation by large carnivores in suppressing prey populations and structuring ecosystems is highly debated, calling for a detailed understanding of carnivore diets. Wolves (Canis lupus) roam across three ... -
Fertilizing behavior of extract of organomineral-activated biochar: low-dose foliar application for promoting lettuce growth
(Peer reviewed; Journal article, 2021)Background: Fostering plant growth and improving agricultural yields by adding “macro”-sized biochar to soil has been extensively explored. However, the impact and mechanism of action of aqueous extracts of biochar applied ... -
Optimal foraging by a large ungulate in an extreme environment: Wild mountain reindeer select snow-free feeding habitats in winter
(Journal article; Peer reviewed, 2021)Optimal foraging models predict that individual animals will optimize net energy gain by intensifying forage activity and/or reducing forage energy cost. Then, the free distribution model predicts an animal's distribution ... -
Seasonal and diel movement patterns of brown bears in a population in southeastern Europe
(Peer reviewed; Journal article, 2021)Most animals concentrate their movement into certain hours of the day depending on drivers such as photoperiod, ambient temperature, inter- or intraspecific competition, and predation risk. The main activity periods of ... -
The interplay between hunting rate, hunting selectivity, and reproductive strategies shapes population dynamics of a large carnivore
(Peer reviewed; Journal article, 2021)Harvest, through its intensity and regulation, often results in selection on female reproductive traits. Changes in female traits can have demographic consequences, as they are fundamental in shaping population dynamics. ... -
Forests buffer the climate-induced decline of body mass in a mountain herbivore
(Peer reviewed; Journal article, 2021)Climate change is known to affect key life-history traits, such as body mass, reproduction, and survival in many species. Animal populations inhabiting mountain habitats are adapted to extreme seasonal environmental ... -
Correcting for enzyme immunoassay changes in long term monitoring studies
(Peer reviewed; Journal article, 2021)Enzyme immunoassays (EIAs) are a common tool for measuring steroid hormones in wildlife due to their low cost, commercial availability, and rapid results. Testing technologies improve continuously, sometimes requiring ... -
Cosmogenic exposure dating (36Cl) of landforms on Jan Mayen, North Atlantic, and the effects of bedrock formation age assumptions on 36Cl ages
(Peer reviewed; Journal article, 2021)Jan Mayen is a small volcanic island situated 550 km north of Iceland. Glacial sediments and landforms are relatively common on the island but, so far, only a few of them have been dated. In this study, we present and ... -
Aquatic habitat use in a semi-aquatic mammal: the Eurasian beaver
(Peer reviewed; Journal article, 2021)Background: Semi-aquatic mammals exploit resources both on land and in water and may require both to meet their habitat requirements including food- and building resources, refuges, and for social interactions with ... -
Contrasting Growth Response of Evergreen and Deciduous Arctic-Alpine Shrub Species to Climate Variability
(Journal article; Peer reviewed, 2021)Broad-scale changes in arctic-alpine vegetation and their global effects have long been recognized and labeled one of the clearest examples of the terrestrial impacts of climate change. Arctic-alpine dwarf shrubs are a key ... -
Dendrometer Measurements of Arctic-Alpine Dwarf Shrubs and Micro-Environmental Drivers of Plant Growth - Dataset from Long-Term Alpine Ecosystem Research in Central Norway (LTAER-NO)
(Journal article; Peer reviewed, 2021)Here, we present fine-scale measurements of stem diameter variation from three common arctic-alpine dwarf-shrub species monitored in two mountain regions of Central Norway. All three species (Betula nana, Empetrum nigrum ...
