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 ... -
When do ungulates override the climate? Defining the interplay of two key drivers of northern vegetation dynamics
(Doctoral theses at NTNU;2021:119, Doctoral thesis, 2021) -
When Fluorescence Is not a Particle: The Tissue Translocation of Microplastics in Daphnia magna Seems an Artifact
(Journal article; Peer reviewed, 2019)Previous research reported the translocation of nano‐ and microplastics from the gastrointestinal tract to tissues in Daphnia magna, most prominently of fluorescent polystyrene beads to lipid droplets. For particles >300 ... -
When things go wrong: intra-season dynamics of breeding failure in a seabird
(Journal article; Peer reviewed, 2014)During breeding, long-lived species face important time and energy constraints that can lead to breeding failure when food becomes scarce. Despite the potential implications of intra-season dynamics in breeding failure for ... -
Where to live and how to get there - Insights from the secret lives of cnidarians
(Master thesis, 2023)Koraller og anemoner er anthozoer og medlemmer av phylumet nesledyr (cnidaria) med en kompleks livssyklus, som inkluderer pelagiske larve- og sessile voksenstadier. Under utviklingen omdannes embryoet til en planulalarve, ... -
White-tailed eagle (Haliaeetus albicilla) feathers from Norway are suitable for monitoring of legacy, but not emerging contaminants
(Journal article, 2018)While feathers have been successfully validated for monitoring of internal concentrations of heavy metals and legacy persistent organic pollutants (POPs), less is known about their suitability for monitoring ofemerging ... -
Whole genome data reveals possible speciation in the common peatmoss Sphagnum compactum
(Master thesis, 2023)Et langvarig syn innenfor mosebiogeografi er at moser har svært store utbredelsesområder og lave artsdannelse. Her studerer jeg den genetiske strukturen til den vanlige og utbredte torvmosen Sphagnum compactum Lam. & DC. ... -
Whole-cell response to nitrogen depletion in the diatom Phaeodactylum tricornutum
(Journal article; Peer reviewed, 2015)Algal growth is strongly affected by nitrogen (N) availability. Diatoms, an ecologically important group of unicellular algae, have evolved several acclimation mechanisms to cope with N deprivation. In this study, we ... -
Whole-genome resequencing of extreme phenotypes in collared flycatchers highlights the difficulty of detecting quantitative trait loci in natural populations
(Journal article, 2016)Dissecting the genetic basis of phenotypic variation in natural populations is a long-standing goal in evolutionary biology. One open question is whether quantitative traits are determined only by large numbers of genes ... -
Why do brood parasitic birds lay strong-shelled eggs?
(Journal article, 2012)Brood parasitic birds constitute a model system for the study of coevolution. Such parasites are unique by having evolved unusually thick eggshells for their body size. Thick eggshells have been hypothesized to evolve as ... -
Why do cuckoos lay strong-shelled eggs? Tests of the puncture resistance hypothesis
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:156, Doctoral thesis, 2010)Coevolution occurs when two or more interacting species have a reciprocal effect on each other. Avian obligate brood parasites and their hosts represent a classical example of coevolution and studies of such interactions ... -
Why Do Some Areas Have Higher Density of Forest Grouse Than Others?
(Master thesis, 2011)Landscape and vegetation data were extracted from digital maps by use of GIS. These data together with predator and management related data collected from landowners and hunter's associations in Norway, were used as ... -
Why do we find dead bumblebees under linden trees?
(Peer reviewed; Journal article, 2022)1. Linden trees (Tilia spp.) have for a long time been associated with bumblebee (Bombus spp.) mortality in Europe and North America. Several explanations have been suggested for this phenomenon. This study aimed to explore ... -
Wildlife conservation and local land use conflicts in Western Serengeti, Tanzania
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:221, Doctoral thesis, 2006)The pre-colonial traditional societies in Western Serengeti were physically and spiritually connected to animal species and plants in their surrounding environments. This link contributed to sustainable use and harmonious ...
