Whole transcriptomic network analysis using Co-expression Differential Network Analysis (CoDiNA)
(Journal article; Peer reviewed, 2020) -
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 ... -
Wide field-of-view Fourier Ptychography microscopy based on Fresnel propagation scheme
(Peer reviewed; Journal article, 2022)Fourier ptychographic microscopy (FPM) is a computational imaging method that gives a significantly increased space-bandwidth product, in practice high resolution combined with a wide field of view. In this article, we ... -
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 ... -
Wildlife Conservation and People’s Livelihoods: Lessons Learnt and Considerations for Improvements. The Case of Serengeti Ecosystem, Tanzania
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:153, Doctoral thesis, 2010)Protected areas have long been recognized as the single most important method of conserving wildlife and preserving biodiversity. However, the protectionism model of management of protected areas has often displaced people ... -

Wind-driven upwelling of iron sustains dense blooms and food webs in the eastern Weddell Gyre
(Peer reviewed; Journal article, 2023)The Southern Ocean is a major sink of anthropogenic CO2 and an important foraging area for top trophic level consumers. However, iron limitation sets an upper limit to primary productivity. Here we report on a considerably ... -
Winds and tides in the mid-latitude southern hemisphere upper mesosphere recorded with the Falkland Islands SuperDARN radar
(Journal article; Peer reviewed, 2011)Meteor wind data from the first year of operation of the Falkland Islands SuperDARN radar (52 S, 59 W) are used to characterize the atmospheric tides and background winds in the upper mesosphere above the South Atlantic. ... -
Winter gardening at 78° North: measuring extreme warm spell impacts on above- and below-ground biomass of vascular plant communities
(Master thesis, 2022)Global oppvarming gjer dei arktiske vintrane varmare og våtare, noko som fører til ei auke i ekstreme vêrfenomen på vinteren. Døme på slike vêr-hendingar er regn som frys på og dannar eit islag som «kapslar inn» tundraen ... -
Wire and Arc Additive Manufacturing with TiC-Nanoparticle Reinforced AA5183 Alloy
(Peer reviewed; Journal article, 2020)Wire and arc additive manufacturing of aluminium-ceramic composites shows great potential to produce high strength materials. By incorporation of nanoparticles in the feedstock wire, fine-grained material with low ... -
Wire arc additive manufacturing of AA5183 with TiC nanoparticles
(Peer reviewed; Journal article, 2021)Aluminium alloys processed by wire arc additive manufacturing (WAAM) exhibit a relatively coarse microstructure with a columnar morphology. A powerful measure to refine the microstructure and to enhance mechanical properties ... -
Wire Arc Additive Manufacturing of Aluminium Alloys
(Doctoral theses at NTNU;2021:263, Doctoral thesis, 2021)Summary Additive manufacturing of metals has gained considerable attention from the industry and academia in the last decade. The attributes to create stand-alone components with novel designs and enhanced properties ... -
Wire Arc Additive Manufacturing of an Al-Mg Aluminium Matrix Nanocompsite
(Master thesis, 2020)Målet med denne studien var å benytte 10 mm ekstrudatprofiler fra kontinuerlig skrueekstrusjon av metaller (Metal Continuous Scew Extrusion, MCSE), en ny metode for fast tilstandsproduksjons av metalltråd for additiv ... -
Within-colony segregation of foraging areas: from patterns to processes
(Journal article, 2023-02-27)Spatial segregation of foraging areas among conspecifics breeding in neighbouring colonies has been observed in several colonial vertebrates and is assumed to originate from competition and information use. Segregation ... -
Wolverine foraging strategies in a multiple-use landscape
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:43, Doctoral thesis, 2008)The principal objective of the research project Wolverines in a Changing World was to gain better insights into the role wolverines have in ecosystem dynamics, their adaptation to ecosystem change, and its implications for ...
