Population and distribution of European beavers (Castor fiber)
(Journal article; Peer reviewed, 2003)After being reduced to about 1,200 animals in eight isolated populations by the beginning of the 20th century, European beavers (Castor fiber) have powerfully recovered in both range and population, through relaxation of ... -
Population connectivity: dam migration mitigations and contemporary site fidelity in arctic char
(Journal article; Peer reviewed, 2011-07-14)BACKGROUND: Animal feeding and spawning migrations may be limited by physical barriers and behavioral interactions. Dam constructions (e.g. hydropower) commonly include gateways for fish migrations to sustain ecological ... -
Potential risks of olfactory signaling : the effect of predators on scent marking by beavers
(Journal article; Peer reviewed, 2006)Mammals scent mark their territories to advertise occupancy and ownership. However, signaling with scent for territorial defense can have a negative effect by advertising an individual’s presence and location to predators. ... -
Predicting Habitat Properties Using Remote Sensing Data: Soil pH and Moisture, and Ground Vegetation Cover
(Peer reviewed; Journal article, 2022)Remote sensing data comprise a valuable information source for many ecological landscape studies that may be under-utilized because of an overwhelming amount of processing methods and derived variables. These complexities, ... -

Prevalence of Anaplasma phagocytophilum and Babesia divergens in Ixodes ricinus ticks from Lithuania and Norway
(Journal article; Peer reviewed, 2008)We detected Anaplasma phagocytophilum and Babesia divergens in Ixodes ricinus ticks collected from different locations in Lithuania and Norway by using the Taq Man based real-time PCR method. The msp2 gene of A. phagocytophilum ... -
Prevalence of Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum in questing Ixodes ricinus ticks in relation to the density of wild cervids
(Journal article; Peer reviewed, 2009-11-27)BACKGROUND: Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum have been considered as pathogens in animals and humans. The role of wild cervids in the epidemiology is not clear. We analyzed questing Ixodes ... -
Prevalence of tick-borne encephalitis virus in questing Ixodes ricinus nymphs in southern Scandinavia and the possible influence of meteorological factors
(Peer reviewed; Journal article, 2023)Ixodes ricinus ticks are Scandinavia's main vector for tick-borne encephalitis virus (TBEV), which infects many people annually. The aims of the present study were (i) to obtain information on the TBEV prevalence in ... -

Proteolysis inhibition by hibernating bear serum leads to increased protein content in human muscle cells
(Journal article; Peer reviewed, 2018)Muscle atrophy is one of the main characteristics of human ageing and physical inactivity, with resulting adverse health outcomes. To date, there are still no efficient therapeutic strategies for its prevention and/or ... -
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 ... -
Quantifying long-term stress in brown bears with the hair cortisol concentration: a biomarker that may be confounded by rapid changes in response to capture and handling
(Journal article; Peer reviewed, 2014)The measurement of cortisol in hair is becoming important in studying the role of stress in the life history, health and ecology of wild mammals. The hair cortisol concentration (HCC) is generally believed to be a reliable ... -

Red fox, Vulpes vulpes, kills a European beaver, Castor fiber, kit
(Journal article; Peer reviewed, 1996)We observed an adult Red Fox (Vulpes vulpes) attack, kill and partially consume a 2-month-old female kit European Beaver (Castor fiber) near its lodge in Norway. The inner organs were consumed first. One adult beaver ... -
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 ... -
Reinsdyrstammen på Hardangervidda for stor
(Journal article, 1981)Hardangervidda, in Southern Norway, is the largest mountain plateau in Europe (Fig. 1). It is approximately 10000 km2 in area and lies mostly between 1100 and 1300 m a.s.l. The topography and vegetational cover produce a ... -

Repeated five-day administration of L-BMAA, microcystin-LR, or as mixture, in adult C57BL/6 mice - lack of adverse cognitive effects
(Journal article; Peer reviewed, 2018)The cyanobacterial toxins β-methylamino-L-alanine (L-BMAA) and microcystin-LR (MC-LR; a potent liver toxin) are suspected to cause neurological disorders. Adult male C57BL/6JOlaHsd mice aged approximately 11 months were ... -
Resident beavers (Castor canadensis) do not discriminate between castoreum scent marks from simulated adult and subadult male intruders
(Journal article; Peer reviewed, 2006)Subadult intruding beavers (Castor spp.) could be expected to pose a higher threat than adults to territory holders because, unlike adults who usually own a territory, subadults need to acquire a territory and a mate to ... -
