Community-wide mesocarnivore response to partial ungulate migration
(Journal article, 2014)1. Mesocarnivores increase in number and geographic range in human-disturbed ecosystems with cascading negative impact on biodiversity. To mitigate such impacts, it is essential to identify the proximate causes of such ... -
Age-Related Mercury Contamination and Relationshipwith Luteinizing Hormone in a Long-Lived Antarctic Bird
(Journal article; Peer reviewed, 2014)Seabirds, as long-lived top predators, accumulate contaminants such as mercury (Hg), an established endocrine disruptor. In long lived species hormonal secretion varies with age; therefore, Hg-induced endocrine disruption ... -
The spatio-temporal distribution of wild and domestic ungulates modulates lynx kill rates in a multi-use landscape
(Journal article; Peer reviewed, 2014)Depredation on livestock and competition with hunters for game species are prominent among the conflicts that the return of large carnivores generates in multi-use landscapes. The relative magnitude of the conflict strongly ... -
Public beliefs about high-voltage powerlines in Norway, Sweden and the United Kingdom: A comparative survey
(Journal article; Peer reviewed, 2014)As countries worldwide, and particularly in Europe, move to increase deployment of low carbon energy sources, significant investments in new transmission networks are planned. However, past cases of public opposition – ... -
Low cardiac output as physiological phenomenon in hibernating, free-ranging Scandinavian brown bears (Ursus arctos) - an observational study
(Journal article; Peer reviewed, 2014)Background: Despite 5-7 months of physical inactivity during hibernation, brown bears (Ursus arctos) are able to cope with physiological conditions that would be detrimental to humans. During hibernation, the tissue ... -
Time and size at seaward migration influence the sea survival of Salmo salar
(Peer reviewed; Journal article, 2014)Whether time of seaward migration of young Atlantic salmon Salmo salar influences their subsequent survival and growth was investigated in the River Imsa, south-western Norway. Salmo salar were tagged when moving downstream ... -
Phenology and cover of plant growth forms predict herbivore habitat selection in a high latitude ecosystem
(Journal article; Peer reviewed, 2014)The spatial and temporal distribution of forage quality is among the most central factors affecting herbivore habitat selection. Yet, for high latitude areas, forage quantity has been found to be more important than quality. ... -
“Å, nå telte han deg også” – er det noe vits da?
(Journal article; Peer reviewed, 2014)Automatiske ferdselstellere benyttes i stadig flere naturområder. Vi får vite hvor mange mennesker som gikk her eller der. Vi sitter med et tall. Men hva sier tallene oss egentlig, og hvordan kan vi bruke dem i en adaptiv ... -
The relative importance of direct and indirect effects of hunting mortality on the population dynamics of brown bears
(Journal article; Peer reviewed, 2014)There is increasing evidence of indirect effects of hunting on populations. In species with sexually selected infanticide (SSI), hunting may decrease juvenile survival by increasing male turnover.We aimed to evaluate the ... -
Allelic Variation in a Willow Warbler Genomic Region Is Associated with Climate Clines
(Journal article, 2014)Local adaptation is an important process contributing to population differentiation which can occur in continuous or isolated populations connected by various amounts of gene flow. The willow warbler (Phylloscopus trochilus) ... -
Spatial variation in the relationship between performance and metabolic rate in wild juvenile Atlantic salmon
(Journal article; Peer reviewed, 2014) -
Community-wide mesocarnivore response to partial ungulate migration
(Journal article; Peer reviewed, 2014)1.Mesocarnivores increase in number and geographic range in human-disturbed ecosystems with cascading negative impact on biodiversity. To mitigate such impacts, it is essential to identify the proximate causes of such ... -
Lynx predation on semi-domestic reindeer: do age and sex matter?
(Journal article; Peer reviewed, 2014)The Eurasian lynx is an efficient stalking predator mainly selecting small-sized ungulates. In northern Scandinavia, semi-domestic reindeer are the only ungulate species available for Eurasian lynx year round and consequently ... -
Endocrine and Fitness Correlates of Long-Chain Perfluorinated Carboxylates Exposure in Arctic Breeding Black-Legged Kittiwakes
(Journal article; Peer reviewed, 2014)Increasing levels of poly- and perfluorinated alkyl substances (PFASs) have recently been described in Arctic biota. These emerging substances are of concern given their resistance to degradation and metabolization. Some ... -
The stress of being contaminated? Adrenocortical function and reproduction in relation to persistent organic pollutants in female black legged kittiwakes
(Journal article; Peer reviewed, 2014)High levels of environmental pollutants such as persistent organic pollutants (POPs) including PCB and DDT have been found in the Arctic and many of those pollutants may impair reproduction through endocrine disruption. ... -
Impacts of wild fishes attracted to open-cage salmonid farms in Norway
(Journal article; Peer reviewed, 2014)Salmonid farming affects both the environment and other industries, with impacts of wild fish attracted to fish farms being a major concern. Here, we summarized existing knowledge on the impacts of such aggregations around ... -
Effects of livestock on occurrence of the Vulnerable red panda Ailurus fulgens in Rara National Park, Nepal
(Journal article; Peer reviewed, 2014)The Vulnerable red panda Ailurus fulgens is endemic to the Himalayas. Anthropogenic activities, including deforestation, have degraded the species’ habitat but the effects of livestock have not been examined. We assessed ... -
Activity patterns of Eurasian lynx are modulated by light regime and individual traits over a wide latitudinal range
(Peer reviewed; Journal article, 2014)The activity patterns of most terrestrial animals are regarded as being primarily influenced by light, although other factors, such as sexual cycle and climatic conditions, can modify the underlying patterns. However, most ... -
Performance of hunting statistics as spatiotemporal density indices of moose (Alces alces) in Norway
(Peer reviewed; Journal article, 2014)Wildlife managers are often asking for reliable information of population density across larger spatial scales. In this study, we examined the spatiotemporal relationships between moose density as estimated by cohort ... -
Record-low primary productivity and highplant damage in the Nordic Arctic Region in2012 caused by multiple weather events andpest outbreaks
(Peer reviewed; Journal article, 2014)The release of cold temperature constraints on photosynthesis has led to increased productivity (greening) in significant parts (32–39%) of the Arctic, but much of the Arctic shows stable (57–64%) or reduced productivity ...
