Vegetation response to climate warming across the forest–tundra ecotone: species-dependent upward movement
(Peer reviewed; Journal article, 2020)Questions Rising temperatures are predicted to cause upward shifts and reorganisation of mountain vegetation. This study analyses how field layer vegetation across the forest–tundra ecotone has responded over a 22‐year ... -
Verdien av miRNA som biomarkør for kreft i prostata: Optimalisering av metode for RNA-isolering av formalinfiksert parafininnstøpt vev, samt undersøkelse av miRNA-uttrykk i ulik grad av prostatakreft
(Master thesis, 2012)Prostatakreft er den kreftformen som hyppigst rammer norske menn og dødelighet på grunn av avansert kreft i prostata er et klinisk problem. For å forstå molekylære ulikheter som skiller progressiv sykdom fra ikke-progressiv ... -
Vigilance Behaviour of Wild Herbivores when Foraging With or Without Livestock.
(Journal article, 2019)In African savannas, and many other rangelands around the world, wildlife presently find themselves interacting with livestock. Many studies have been conducted on vigilance behaviour in response to presence of predators ... -
Virkningen av økte næringssaltutslipp fra akvakultur på strukturen i planteplanktonsamfunnet
(Master thesis, 2013)Et mesokosmeforsøk ble gjennomført over 20 dager i Hopavågen, Sør-Trøndelag. Forsøket ble startet under en typisk sensommer med resirkulerte næringsstoffer i et stratifisert vannlag (~10 m) og dominans av dinoflagellater ... -
A vision for safer food contact materials: Public health concerns as drivers for improved testing
(Peer reviewed; Journal article, 2023)Food contact materials (FCMs) and food contact articles are ubiquitous in today’s globalized food system. Chemicals migrate from FCMs into foodstuffs, so called food contact chemicals (FCCs), but current regulatory ... -
Visual Phenotype Matching: Cues to Paternity Are Present in Rhesus Macaque Faces
(Journal article; Peer reviewed, 2013-02-22)The ability to recognize kin and thus behaviourally discriminate between conspecifics based on genetic relatedness is of importance both in acquiring inclusive fitness benefits and to enable optimal inbreeding. In primates, ... -
Visualization of Nuclear Factor Kappa B (NF-κB) Translocation and Quantitative Processing of Confocal Microscopy Images in Synoviocytes
(Master thesis, 2016)Rheumatoid arthritis is a chronic, progressive, inflammatory autoimmune disease that can cause severe joint destruction and disability. There have been major strides in understanding how the inflammatory process leads to ... -
Volatile organic compound release across a permafrost-affected peatland
(Peer reviewed; Journal article, 2023)As the permafrost region experiences unprecedented climate warming, accelerated decomposition rates are potentially switching these cold landscapes to a hotspot of carbon emissions. In addition to the more widely studied ... -
Vurdering av GellyFeed metoden som hygienisering ved bruk av akvakulturdyr i fôr til akvakulturdyr. Uttalelse fra Faggruppe for fôr til terrestriske og akvatiske dyr i Vitenskapskomiteen for mattrygghet
(VKM Report;, Research report, 2008)Stiftelsen Rubin (senere GellyFeed AS) har siden 1991 jobbet med å utvikle fôr basert på avskjær fra villfisk til bruk i fôr til oppdrettsfisk. På grunn av fare for smitteoverføring, ble det utviklet et eget fôrkonsept ... -
Vurdering av smitterisiko ved fôring av oppdrettsfisk med ubehandlet villfanget fisk. Uttalelse fra Faggruppe for dyrehelse og dyrevelferd (dyrevern) i Vitenskapskomiteen for mattrygghet
(VKM Report;, Research report, 2007)Vurderingen er utarbeidet etter forespørsel fra Mattilsynet i brev av 28. mars 2007 der Vitenskapskomiteen for mattrygghet (VKM) ble bedt om å foreta en vurdering av smitterisiko knyttet til bruk av ... -
Warmer and wetter winters: characteristics and implications of an extreme weather event in the High Arctic
(Journal article; Peer reviewed, 2014)One predicted consequence of global warming is an increased frequency of extreme weather events, such as heat waves, droughts, or heavy rainfalls. In parts of the Arctic, extreme warm spells and heavy rain-on-snow (ROS) ... -
Water treatment as an approach to increase microbial control in the culture of cold water marine larvae
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:231, Doctoral thesis, 2011) -
Weather affects temporal niche partitioning between moose and livestock
(Journal article; Peer reviewed, 2017)Co-existing species at the same trophic level often segregate with respect to diet, habitat use, or spatial distribution, reducing their direct competition for resources. However, temporal patterns in species-specific ... -
Weighting of Celestial and Terrestrial Cues in the Monarch Butterfly Central Complex
(Peer reviewed; Journal article, 2022)Monarch butterflies rely on external cues for orientation during their annual long-distance migration from Northern US and Canada to Central Mexico. These external cues can be celestial cues, such as the sun or polarized ... -
What you extract is what you see: Optimising the preparation of water and wastewater samples for in vitro bioassays
(Journal article; Peer reviewed, 2019)The assessment of water quality is crucial for safeguarding drinking water resources and ecosystem integrity. To this end, sample preparation and extraction is critically important, especially when investigating emerging ... -
