Relationships Between Persistent Organic Pollutants (POPs) and Plasma Clinical-Chemical Parameters in Polar Bears (Ursus maritimus) from Svalbard, Norway.
(Master thesis, 2012)In the present study, clinical-chemical parameters in relationship to persistent organic pollutants (POPs) were investigated in plasma samples from polar bears (Ursus maritimus) captured at Svalbard in 2007. The clinical-chemical ... -
Relationships between POPs, biometrics and circulating steroids in male polar bears (Ursus maritimus) from Svalbard
(Journal article; Peer reviewed, 2017)The aim of this study was to determine the effects of persistent organic pollutants (POPs) and biometric variables on circulating levels of steroid hormones (androgens, estrogens and progestagens) in male polar bears (Ursus ... -
Relative performance of salmonid phenotypes across environments and competitive intensities
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:132, Doctoral thesis, 2011) -
Relevance of nano- and microplastics for freshwater ecosystems: a critical review
(Journal article; Peer reviewed, 2018)The current paper critically reviews the state-of-the-science on (1) microplastics (MP) types and particle concentrations in freshwater ecosystems, (2) MP and nanoplastics (NP) uptake and tissue translocation, (3) MP/NP-induced ... -
Remote sensing of marine environment: Applied surveillance with focus on optical properties of phytoplankton, coloured organic matter and suspended matter
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:178, Doctoral thesis, 2009)Light from the Sun reaching the Earth and sea surface contains the entire wavelength band from ultraviolet (180-400 nm), visible (400-700 nm) and far into the infrared and radio wave region (>700 nm). The light penetrates ... -
Remote Sensing of the Tautra Ridge: An Overview of the World’s Shallowest Cold-Water Coral Reefs
(Peer reviewed; Journal article, 2022)On the Tautra Ridge – a 39-100 m deep morainic sill located in the middle of the Trondheimsfjord, Norway – some of the world’s shallowest known occurrences of the scleractinian cold-water coral (CWC) Desmophyllum pertusum ... -
Repeatability and Flexibility in the Migration Strategies of an Arctic Seabird
(Master thesis, 2016)The strategy of migration has evolved independently in many animal groups, but it is most widely and well developed in birds. Migrating species are expected to be severely affected by human induces climate change, and the ... -
Repeatability in isotopic signatures is linked to consistent individual migration strategies and individual specialization in a long-distance migratory seabird
(Master thesis, 2018)Animal populations can consist of specialized individuals with different foraging strategies. There could be several advantages for specialized individuals, such as higher foraging efficiency, breeding success and survival. ... -
Repeatable individual variation in migration timing in two anadromous salmonids and ecological consequences
(Journal article; Peer reviewed, 2020)Consistent individual differences in behavior have been demonstrated for many animals, but there are few studies of consequences of such repeated behavior in the wild. We tested consistency in migration timing to and from ... -
Repeatable Territorial Aggression in a Neotropical Poison Frog
(Peer reviewed; Journal article, 2022)Intra-specific aggressive interactions play a prominent role in the life of many animals. While studies have found evidence for repeatability in boldness, activity, and exploration in amphibians, we know relatively little ... -
Representation of pheromones, interspecific signals, and plant odors in higher olfactory centers; mapping physiologically identified antennal-lobe projection neurons in the male heliothine moth
(Journal article; Peer reviewed, 2014)The arrangement of anatomically separated systems for information about general and pheromone odorants is well documented at the initial levels of the olfactory pathway both in vertebrates and insects. In the primary ... -
Reproductive and migratory challenges inflicted on migrant brown trout ( Salmo trutta L. ) in a heavily modified river
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:136, Doctoral thesis, 2012) -
Reproductive strategies in Scandinavian brown bears
(Doctoral thesis, 2003)Denne avhandlingen tar for seg noen sentrale aspekt ved reproduktive strategier hos brunbjørn. Første del tar for seg strategier for foreldreomsorg og hvordan disse påvirker størrelsen og overlevelsen på avkommet. Deretter ... -
Requirements Elicitation On Integrating Clinical Guidelines To Electronic Patient Record: An Empirical Study
(Master thesis, 2012)There is little research on the requirements elicitation of integrating of clinical guidelines and electronic patient record while in this master project I managed to use different methods to collect and elicit requirements ... -
Research on sablefish (Anoplopoma fimbria) suggests that limited capacity to increase heart function leaves hypoxic fish susceptible to heat waves
(Peer reviewed; Journal article, 2021)Studies of heart function and metabolism have been used to predict the impact of global warming on fish survival and distribution, and their susceptibility to acute and chronic temperature increases. Yet, despite the fact ... -
Research progress on gut health of farmers teleost fish: a viewpoint concerning the intestinal mucosal barrier and the impact of its damage
(Journal article; Peer reviewed, 2020) -
Resident bird species track inter-annual variation in spring phenology better than long-distance migrants in a subalpine habitat
(Journal article; Peer reviewed, 2022) -
Resource allocation under stress: mechanisms and strategies in a long-lived bird
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:25, Doctoral thesis, 2014)The marine environment is currently undergoing critical modification in the wake of global climate change. Marine animals are, consequently, expected to experience increasing periods of nutritionally stressful conditions. ... -
