Varegrinder foran turbininntak ved elvekraftverk; barrierer eller inngangsport for fisk?
(Journal article; Peer reviewed, 2013)Trash racks at hydropower turbine intakes; barriers or entry gates for fish? At all run-ofriver hydro power plants, water is diverted through turbines for power generation. Trash racks protect the turbines from harmful ... -
Variability in nomadism: environmental gradients modulate the movement behaviors of dryland ungulates
(Journal article; Peer reviewed, 2019)Studying nomadic animal movement across species and ecosystems is essential for better understanding variability in nomadism. In arid environments, unpredictable changes in water and forage resources are known drivers of ... -
Variations in coastal fish species composition captured by traps in Romsdalsfjord, Western Norway
(Peer reviewed, 2016)Fish traps are widely used in Norwegian fjords, especially those designed for monitoring salmonid populations in the marine environment, although many other marine fish species are also captured. The composition and ... -
The viability of the crustacean Eurycercus lamellatus (Branchiopoda, Cladocera) in a high mountain area in southern Norway
(Journal article, 2020)The branchiopod Eurycercus lamellatus is widely distributed in Norwegian lakes, ranging from coastal to alpine areas. On the Hardangervidda mountain plateau in southern Norway, E. lamellatus was searched for in 144 lakes ... -
Viruses on the menu: The appendicularian Oikopleura dioica efficiently removes viruses from seawater
(Journal article; Peer reviewed, 2017)Appendicularians are planktonic marine tunicates with elaborate filter-feeding houses that can efficiently trap particles as small as 0.2 lm. While marine viruses are seldom considered outside their role in disease ... -
Vole and lemming activity observed from space
(Journal article; Peer reviewed, 2012)Predicting the impacts of present global warming requires an understanding of the factors controlling plant biomass and production. The extent to which they are controlled by bottom-up drivers such as climate, nutrient and ... -
Vulnerability and resilience of the carbon exchange of a subarctic peatland to an extreme winter event
(Journal article; Peer reviewed, 2018)Extreme winter events that damage vegetation are considered an important climatic cause of arctic browning—a reversal of the greening trend of the region—and possibly reduce the carbon uptake of northern ecosystems. ... -
Walking as urban outdoor recreation: public health for everyone
(Journal article; Peer reviewed, 2017)This study aims to investigate whether the frequency of neighbourhood walks (both for recreation and for transport) is associated with various indicators of demographic and socio-economic position, indicators of selfreported ... -
What’s the catch with lumpsuckers? A North Atlantic study of seabird bycatch in lumpsucker gillnet fisheries
(Peer reviewed, 2019)Worldwide, incidental bycatch in fisheries is a conservation threat to many seabird species. Although knowledge on bycatch of seabirds has increased in the last decade, most stems from longline fisheries and the impacts ... -
When context matters: Spatial prediction models of environmental conditions can identify target areas for wild bee habitat management interventions
(Peer reviewed, 2019)Prioritizing where to implement management interventions is critical because managers have limited Budgets and the effect of habitat enhancement depends on site-specific environmental conditions. Field experiments can ... -
When is it acceptable to kill a strictly protected carnivore? Exploring the legal constraints on wildlife management within Europe’s Bern Convention
(Journal article; Peer reviewed, 2017)As wolf populations expand across Europe, many countries face challenges in finding ways to address the concerns of some elements among the rural stakeholders who are being asked to share their landscapes with wolves for ... -
When we cannot have it all: Ecosystem services trade-offs in the context of spatial planning
(Peer reviewed, 2017)Spatial planning have to deal with trade-offs between various stakeholders’ wishes and needs as part of planning and management of landscapes, natural resources and/or biodiversity. To make ecosystem services (ES) trade-off ... -
Where do the treeless tundra areas of northern highlands fit in the global biome system: toward an ecologically natural subdivision of the tundra biome
(Peer reviewed, 2015)According to some treatises, arctic and alpine sub-biomes are ecologically similar, whereas others find them highly dissimilar. Most peculiarly, large areas of northern tundra highlands fall outside of the two recent ... -
Who are legitimate stakeholders? National and local perceptions of environmental change in the Lofoten islands, Norway
(Journal article, 2019)Debates on future resource policy in northern regions raises the question of who are the legitimate stakeholders to include in policy deliberations? The Lofoten archipelago in Northern Norway is a world-class nature tourism ... -

Widespread genetic introgression of escaped farmed Atlantic salmon in wild salmon populations
(Peer reviewed, 2016)Farmed Atlantic salmon (Salmo salar) escape from net pens and enter rivers to spawn, potentially resulting in genetic introgression and reduced fitness of wild salmon. Here, we quantify genetic introgression of farmed to ... -
Wildlife in a Politically Divided World: Insularism Inflates Estimates of Brown Bear Abundance
(Peer reviewed, 2015)Political borders dictate how biological diversity is monitored and managed, yet wild animals often move freely between jurisdictions. We quantified bias in brown bear (Ursus arctos) abundance estimates introduced when ... -
Wind turbines cause functional habitat loss for migratory soaring birds
(Journal article; Peer reviewed, 2019)1 . Wind energy production has expanded to meet climate change mitigation goals, but negative impacts of wind turbines have been reported on wildlife. Soaring birds are among the most affected groups with alarming fatality ... -
Winter decrease of zooplankton abundance and biomass in subalpine oligotrophic Lake Atnsjøen (SE Norway)
