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 ... -
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 ... -
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 ... -
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 ... -
World checklist of hornworts and liverworts
(Journal article; Peer reviewed, 2016)A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here present the first-ever ... -
Xandarovula patula (Gastropoda: Ovulidae) new to Scandinavia
(Journal article; Peer reviewed, 2011)In August 2009 six specimens of the ovulid gastropod Xandarovula patula (Pennant, 1777) (formerly known as Simnia patula Pennant, 1777), were found in dredge samples from a locality west of Smögen in western Sweden (58°22′N ... -
Zebrafish (Danio rerio) behaviour is largely unaffected by elevated pCO2
(Peer reviewed; Journal article, 2016)Ocean acidification, the decrease in ocean pH caused by anthropogenic emission of carbon dioxide, can cause behavioural disturbances in marine teleost species. We investigated whether AB-strain zebrafish (Danio rerio) show ... -
Zooplankton and sediment fluxes in two contrasting fjords reveal Atlantification of the Arctic
(Peer reviewed; Journal article, 2021)Svalbard fjords are facing a significant increase in Atlantic water inflow, which influences all ecosystem components, thus the objective of this study was to assess how recent Atlantification impacts the functioning of ... -
