The impact of volcanism on Scandinavian climate and human societies during the Holocene: Insights into the Fimbulwinter eruptions (536/540 AD)
(Peer reviewed; Journal article, 2024)Recent paleoclimatic research has revealed that volcanic events around 536–540 AD caused severe, short-term global cooling. For this same period, archeological research from various regions evidences significant cultural ... -
Impacts of human disturbance on flight response and habitat use of red deer
(Peer reviewed; Journal article, 2022)Many wild animals perceive humans as predators, and human disturbance, especially in the form of hunting, triggers antipredatory behavior among prey. Yet, knowledge of how game species react to different types of human ... -
The importance of aquatic macrophytes in a eutrophic tropical shallow lake
(Journal article; Peer reviewed, 2021)Inlay Lake is the second largest natural lake in Myanmar. Located in Shan State, in the eastern part of the country, it is a known biodiversity hotspot. The lake is negatively affected by an increasing local human population ... -
Importance of mountain height and latitude for the altitudinal distribution limits of vascular plants in Scandinavia: are the mountains high enough?
(Journal article; Peer reviewed, 2010)The main aim of the present paper was to study regional differences in the altitudinal distribution limits of vascular plants in relation to mountain height and latitudinal position. Altitudinal limits from previously ... -
Improved Environmental Status: 50 Years of Declining Fish Mercury Levels in Boreal and Subarctic Fennoscandia
(Journal article; Peer reviewed, 2019)Temporally (1965–2015) and spatially (55°–70°N) extensive records of total mercury (Hg) in freshwater fish showed consistent declines in boreal and subarctic Fennoscandia. The database contains 54 560 fish entries (n: pike ... -
Improving biome and climate modelling for a set of past climate conditions: evaluating bias correction using the CDF-t approach
(Journal article, 2023)Climate model simulations are inherently biased. It is a notably difficult problem when dealing with climate impact assessments and model-data integration. This is especially true when looking at derived quantities such ... -
Improving Utilization of Maximal Oxygen Uptake and Work Economy in Recreational Cross-Country Skiers With High-Intensity Double-Poling Intervals
(Journal article; Peer reviewed, 2020)Purpose: To investigate the effect of a double-poling (DP) high-intensity aerobic interval-training (HIT) intervention performed without increasing total HIT volume. This means that regular HIT training (eg, running) was ... -
Increased mRNA expression levels of ERCC1, OGG1 and RAI in colorectal adenomas and carcinomas
(Journal article; Peer reviewed, 2006-08-16)BACKGROUND: The majority of colorectal cancer (CRC) cases develop through the adenoma-carcinoma pathway. If an increase in DNA repair expression is detected in both early adenomas and carcinomas it may indicate that low ... -
Individual recognition of Eurasian beavers (Castor fiber) by their tail patterns using a computer-assisted pattern-identification algorithm
(Peer reviewed; Journal article, 2024)Individual recognition of animals is an important aspect of ecological sciences. Photograph-based individual recognition options are of particular importance since these represent a non-invasive method to distinguish and ... -
Infanticide as a male reproductive strategy has a nutritive risk effect in brown bears
(Journal article; Peer reviewed, 2013-10-02)Behavioural strategies to reduce predation risk can incur costs, which are often referred to as risk effects. A common strategy to avoid predation is spatio-temporal avoidance of predators, in which prey typically trade ... -
Infestation of mice and voles with Ixodes ricinus ticks in Lithuania and Norway
(Journal article; Peer reviewed, 2009)A total of 693 small rodents were live-trapped in Lithuania and Norway. In Lithuania, the mice Apodemus flavicollis and A. agrarius were more frequently infested with ticks than the voles Microtus arvalis and Myodes ... -
Infestation with Ixodes ricinus ticks on migrating passerine birds in Lithuania and Norway
(Journal article; Peer reviewed, 2009)Ticks are known to carry several pathogenic agents of human diseases. To define the role of migrating birds as host and disseminators of ticks in Lithuania and Norway we analysed immature stage of ticks feeding on different ... -

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 ... -
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 ... -
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. ... -
Invasive North American beaver Castor canadensis in Eurasia: a review of potential consequences and a strategy for eradication
(Journal article; Peer reviewed, 2012-12)Seven North American beavers Castor canadensis (Cc) were introduced into Finland in 1937 to supplement an ongoing reintroduction of the nearly extinct Eurasian beaver C. fiber (Cf). At that time, many zoologists recognised ... -
Investigating and analysing the summer season soil temperature conditions on the extensive green roofs in Oslo, Norway
(Peer reviewed; Journal article, 2020)Recently, green roofs have been investigated in-creasingly to improve the quality of municipal environment particularly to reduce the urban heat island effect and storm water runoff. Soil temperature is one of the most ...
