Ungulate population monitoring in an open tundra landscape:distance sampling versus total counts
(Journal article; Peer reviewed, 2017)Researchers and wildlife managers strive for low bias and high precision (i.e. high accuracy) when estimating animal population sizes. Distance sampling is currently one of the most widely used monitoring methods. However, ... -
Ungulates in a dynamic and increasingly human dominated landscape
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:28, Doctoral thesis, 2013) -
UniBioDicts: Unified access to biological dictionaries
(Peer reviewed; Journal article, 2020)We present a set of software packages that provide uniform access to diverse biological vocabulary resources that are instrumental for current biocuration efforts and tools. The Unified Biological Dictionaries (UniBioDicts ... -
Unique photosynthetic electron transport tuning and excitation distribution in heterokont algae
(Journal article; Peer reviewed, 2019)Heterokont algae are significant contributors to marine primary productivity. These algae have a photosynthetic machinery that shares many common features with that of Viridiplantae (green algae and land plants). Here we ... -
Universality of Torpor Expression in Bats
(Peer reviewed; Journal article, 2022)Although heterothermy is employed by species at a global level within the order of Chiroptera (bats), the possibility of torpor being expressed in bat species inhabiting warmer climate zones has been explored only in the ... -
Unmanned vehicle and hyperspectral imager for a more rapid microplastics sampling and analysis.
(Journal article, 2023)In this paper, we present a proof-of-concept study aiming to improve the sampling and analysis of microplastics (MPs) by implementing a novel methodology combining an autonomous surface vehicle and a near-infrared hyperspectral ... -
Unraveling Regulated Cell Death in Plants Challanges and Perspectives using Mass Spectrometry Imaging
(Master thesis, 2023)N ̊ar klimaendringene akselererer og den globale temperaturen øker, utsettes planter for sterkere miljøbelastninger. Planter reagerer p ̊a stress ved ̊a aktivere ulike typer fysiologiske en- dringer i rotmorfologi og ... -
Upcycling of carbon, nitrogen, and phosphorus from aquaculture sludge using the polychaete Hediste diversicolor (OF Müller, 1776) (Annelida: Nereididae)
(Peer reviewed; Journal article, 2023)Introduction: Focusing on circular bioeconomy and finding solutions for managing finite and scarce resources such as phosphorus are issues that need to be addressed across sectors to attain food security. Land-based ... -
Update on frequency decline of Northeast Pacific blue whale (Balaenoptera musculus) calls
(Peer reviewed; Journal article, 2022)Worldwide, the frequency (pitch) of blue whale (Balaenoptera musculus) calls has been decreasing since first recorded in the 1960s. This frequency decline occurs over annual and inter-annual timescales and has recently ... -
Update on GM canola crops as novel sources of omega‐3 fish oils
(Journal article; Peer reviewed, 2018)There is considerable interest in new sources of omega‐3 long‐chain (here defined as fatty acids ≥C20) polyunsaturated fatty acids (LC‐PUFA), specifically eicosapentaenoic acid (EPA; 20:5n‐3) and docosahexaenoic acid (DHA; ... -
Uptake and effects of microplastic particles in selected marine microalgae species; Oxyrrhis marina and Rhodomonas baltica
(Master thesis, 2017)It is estimated that large numbers of microplastics are present in the marine environment and their concentrations are expected to rise in a foreseeable future. Interactions, uptake, and excretion rates as well as effects ... -
Uptake and excretion of polystyrene microplastics in the marine copepod Calanus finmarchicus
(Master thesis, 2017)Studier av opptak og utskillelse av polystyren mikroplast i den marine kopepoden Calanus finmarchicus -
Uptake, organ distribution and physiological effects of an anti-diabetic II drug (metformin) in Atlantic salmon (Salmo salar)
(Master thesis, 2016)Pharmaceutical and personal care products (PPCPs) are recognized as emerging contaminants due to their high occurrence and persistence in the environment. Metformin is an anti-diabetic II drug and one of the most prescribed ... -
Urban aliens and threatened near-naturals: Land-cover affects the species richness of alien- and threatened species in an urban-rural setting
(Peer reviewed; Journal article, 2020)Urbanisation has strong effects on biodiversity patterns, but impacts vary among species groups and across spatial scales. From a local biodiversity management perspective, a more general understanding of species richness ... -
Urbanisation and land-cover change affect functional, but not compositional turnover of bird communities
(Peer reviewed; Journal article, 2023)Liver sinusoidal endothelial cells (LSECs) are fenestrated endothelial cells with a unique, high endocytic clearance capacity for blood-borne waste macromolecules and colloids. This LSEC scavenger function has been ... -
Urbanization erodes niche segregation in Darwin's finches
(Journal article; Peer reviewed, 2018)Urbanization is influencing patterns of biological evolution in ways that are only beginning to be explored. One potential effect of urbanization is in modifying ecological resource distributions that underlie niche ... -
Use of an Autonomous Surface Vehicle reveals small-scale diel vertical migrations of zooplankton and susceptibility to light pollution under low solar irradiance
(Journal article; Peer reviewed, 2018)Light is a major cue for nearly all life on Earth. However, most of our knowledge concerning the importance of light is based on organisms’ response to light during daytime, including the dusk and dawn phase. When it is ... -
Use of different imaging systems for ROV-based mapping of complex benthic habitats
(Master thesis, 2022)Denne studien bruker mini-ROV-er, små fjernstyrte kjøretøyer som bærer kameraer med forskjellige egenskaper som undervanns hyperspektral avbildning (UHI) og høy-definisjon (HD) rød, grønn og blå (RGB) kameraer for å kartlegge ... -
Use of fatty acid profiles to monitor the escapehistory of farmed Atlantic salmon
(Journal article; Peer reviewed, 2015)Farmed Atlantic salmon can escape from fish farms at various stages of their life, from juveniles to large mature fish. Escapees that enter rivers to spawn pose a threat to the genetic integrity of wild populations. ...
