Ultra-small bacteria and archaea exhibit genetic flexibility towards groundwater oxygen content, and adaptations for attached or planktonic lifestyles
(Journal article, 2023)Aquifers are populated by highly diverse microbial communities, including unusually small bacteria and archaea. The recently described Patescibacteria (or Candidate Phyla Radiation) and DPANN radiation are characterized ... -
Under the sea: How can we use heart rate and accelerometers to remotely assess fish welfare in salmon aquaculture?
(Peer reviewed; Journal article, 2023)Recent advances in bio-sensing technologies open for new possibilities to monitor and safeguard the welfare of fishes in aquaculture. Yet before taken into practice, the applicability of all novel biosensors must be ... -
Undersökning av fjädrar från båtgravar i Valsgärde gravbacke

Understanding and overcoming obstacles in adaptive management
(Peer reviewed; Journal article, 2022)Adaptive management (AM) is widely promoted to improve management of natural resources, yet its implementation is challenging. We show that obstacles to the im- plementation of AM are related not only to the AM process per ... -
Understanding the drivers of extensive plant damage in boreal and Arctic ecosystems: Insights from field surveys in the aftermath of damage
(Peer reviewed; Journal article, 2017)The exact cause of population dieback in nature is often challenging to identify retrospectively. Plant research in northern regions has in recent decades been largely focussed on the opposite trend, namely increasing ... -
Unleaded hunting: Are copper bullets and lead-based bullets equally effective for killing big game?
(Journal article; Peer reviewed, 2019)Semi-jacketed lead-cored or copper-based homogenous rifle bullets are commonly used for hunting big game. Ever since their introduction in the 1990’s, copper-based bullets have not been widely accepted by hunters due ... -
Unraveling heterogeneity in the importance of ecosystem services: individual views of smallholders
(Journal article; Peer reviewed, 2018)Stakeholder groups are not homogeneous across individuals and through time, especially in relation to the importance of ecosystem services. However, the approaches commonly used to characterize the average importance and ... -
Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range
(Peer reviewed; Journal article, 2021)Qvenild T, Fjeld E, Fjellheim A, Hammar J, Hesthagen T and Lakka H-K. 2021. Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range. Fauna norvegica ... -
Upstream fishway performance by Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) spawners at complex hydropower dams – is prior experience a success criterion?
(Peer reviewed; Journal article, 2020)Passage of hydropower plants by upstream-migrating salmonid spawners is associated with reduced migration success, and the need for knowledge of fish behavior downstream of dams is widely recognized. In this study, we ... -
Upstream passage of Potamodromous Cyprinids over small weirs: the influence of key-hydraulic parameters
(Peer reviewed; Journal article, 2016)The presence of small weirs, far more numerous than dams, has increased habitat fragmentation on rivers worldwide. This study aims to evaluate the upstream passage performance of a potamodromous cyprinid, the Iberian barbel ... -
Urban cemeteries' potential as sites for cultural encounters
(Journal article; Peer reviewed, 2018)Swensen, Grete; Skår, Margrete. Urban cemeteries' potential as sites for cultural encounters. Mortality 2018 Population increase has drawn attention to the need in cities for easily accessible and attractive public spaces ... -
Urban green. Integrating ecosystem extent and condition data in urban ecosystem accounts. Examples from the Oslo region
(Peer reviewed; Journal article, 2021)The article enhances the knowledge base for the assessment of urban ecosystem services, within the United Nations System of Environmental-Economic Accounting Ecosystem Accounting (SEEA EA), recently adopted as an international ... -
Urban nature in a time of crisis: recreational use of green space increases during the COVID-19 outbreak in Oslo, Norway
(Peer reviewed; Journal article, 2020)The global response to the COVID-19 pandemic has brought with it significant changes to human mobility patterns and working environments. We aimed to explore how social distancing measures affected recreational use of urban ... -
Use of environmental DNA to detect the myxozoan endoparasite Tetracapsuloides bryosalmonae in large Norwegian lakes
(Peer reviewed; Journal article, 2022)Understanding the underlying causes behind human–elephant conflict (HEC)-driven mortality of humans and Environmental DNA (eDNA) is an increasingly used noninvasive and cost-effective method for species detections in ... -
Use of simulation approaches to evaluate the consequences of catch-and-release angling on the migration behaviour of adult Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2016)Given most Atlantic salmon (Salmo salar) released by anglers survive (proportion = 0.97 in this study), eco-nomically and culturally important recreational Atlantic salmon fisheries are increasingly incorporatingcatch-and-release. ... -
Use of Supplementary Feeding Dispensers by Arctic Foxes in Norway
(Peer reviewed; Journal article, 2020)Supplementary feeding is often used as a conservation tool to reverse the decline of food‐limited populations. The arctic fox (Vulpes lagopus) is one of the most endangered mammals in Norway and has been the target of ... -
Using by-catch data from wildlife surveys to quantify climatic parameters and the timing of phenology for plants and animals using camera traps
(Journal article, 2019)Gaining a better understanding of global environmental change is an important challenge for conserving biodiversity. Shifts in phenology are an important consequence of environmental change. Measuring phenology of different ... -
Using genomics to guide seed-sourcing at the right taxonomical level for ecological restoration projects: The complex case of Carex bigelowii s.lat. in Norway
