Plant environmental memory: implications, mechanisms and opportunities for plant scientists and beyond
(Peer reviewed; Journal article, 2023)Plants are extremely plastic organisms. They continuously receive and integrate environmental information and adjust their growth and development to favour fitness and survival. When this integration of information affects ... -
Plant Species Responses to Moose (Alces alces) and Red Deer (Cervus elaphus) Herbivory in Successional Boreal Forests
(Master thesis, 2020)Store beitedyr er en viktig regulerende faktor for artssammensetningen i feltsjiktet i skogsøkosystemer. Hvordan de regulerer ulike økosystemegenskaper varierer blant ulike beitedyr og avhenger i stor grad av deres ... -
Plasma concentrations of organohalogenated contaminants in white-tailed eagle nestlings – The role of age and diet
(Journal article; Peer reviewed, 2019)Concentrations of organohalogenated contaminants (OHCs) can show significant temporal and spatial variation in the environment and wildlife. Most of the variation is due to changes in use and production, but environmental ... -
Plasma melatonin profiles in Common carp (Cyprinus carpio) exposed to indoor photoperiods
(Master thesis, 2011)An intervention against extreme poverty and hunger was introduced in year 2000, when all members of the United Nations agreed on the Millennium Development Goals (MDG). Today, 1.4 billion people live in poverty and hunger, ... -
Plasma melatonin profiles in copper mahseer (Neolissochilus hexagonolepis) kept under natural and manipulated photoperiods
(Master thesis, 2011)Abstract In many countries around the world, health problems related to food access are an increasing threat, and many people today still don?t have access to sufficient protein and energy in their diet. In poor countries ... -

Plasma melatonin profiles in mrigal carp (Cirrhinus mrigala) kept under natural and manipulated photoperiods
(Master thesis, 2012)One major challenge in Asian aquaculture is the limited availability of carp fries. In order to establish out of season supply of fries, knowledge about the pineal melatonin clock and calendar function, and its influence ... -
Plasma melatonin profiles in silver carp (Hypophthalmichthys molitrix) during natural and manipulated photoperiods
(Master thesis, 2012)Photoperiodic manipulation of reproductive events in fish is suggested to secure all-year supply of fish fry in the Nepalese aquaculture. This could significantly improve food security and decrease poverty in Nepal. In ... -
Plasma protein fractions in free-living white-tailed eagle (Haliaeetus albicilla) nestlings from Norway
(Journal article; Peer reviewed, 2019)Background Capillary electrophoresis of plasma proteins has shown great potential as a complementary diagnostic tool for avian species. However, reference intervals for plasma proteins are sparse or lacking for several ... -
Plastic and Associated Chemicals in Cinereous Vulture (Aegypius Monachus): Exposure and Effects
(Master thesis, 2022)Abstract will be available on 2023-07-01 -
Plasticity and adaptive evolution in the body size and shape of Trinidadian guppies
(Master thesis, 2023)Fenotypisk plastisitet beskriver forutsigbare endringer i en fenotype for en gitt genotype som respons på forskjellige miljøer. Plastisitet kan påvirke evolusjonære baner ved å flytte populasjoner enten nærmere (adaptiv ... -
Pollutant exposure and oxidative stress responses in the blue mussel (Mytilus edulis)
(Master thesis, 2020)In the present study, I intended to investigate the pollutant exposure to metals, bisphenols and UV filters, and oxidative stress in blue mussels (Mytilus edulis) with different sizes in two suspected polluted locations ... -
Pollutant Levels, Antioxidants and Potential Genotoxic Effects in Incubating Female Common Eiders (Somateria mollissima)
(Doctoral thesis at NTNU;2016:189, Doctoral thesis, 2016)In the present thesis, environmental exposure to 18 persistent organic pollutants (POPs) and 8 elements, as well as potential antioxidant responses and genotoxic effects in incubating female common eiders (Somateria ... -
Polygalacturonase-inhibiting protein (PGIP) in cultivatedstrawberry (Fragaria x ananassa) : characterisation and induction of the gene following fruit infection by Botrytis cinerea
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:153, Doctoral thesis, 2004)Polygalacturonase-inhibiting proteins (PGIPs) have been demonstrated to play a role in host defense in several plants. The PGIP now cloned from strawberry (Fragaria × ananassa) showed a high degree of homology to other ... -
Population analysis and structure and RNA interference to understand salmon lice biology and a review of the principles of controlling infestation in aquaculture facilities
(Doctoral theses at NTNU;2022:232, Doctoral thesis, 2022)The arthropod salmon louse (Lepeophtheirus salmonis) is a significant hazard to aquaculture and to the wild Atlantic salmon. In a monoculture environment, very high host densities may result in rapid reproduction and in ... -
Population characteristics and estimates of effective population size in a house sparrow metapopulation
(Master thesis, 2011)Effective population size (Ne) is a fundamental concept within biology and can be defined as the size of an ideal Wright-Fisher population in which the rate of genetic drift is the same as in the observed population. Natural ... -
Population dynamics and resting egg production in Daphnia: Interactive effects of mercury, population density and temperature
(Peer reviewed; Journal article, 2021)Toxicity studies on freshwater organisms are commonly conducted by quantifying effects on asexual (clonal) reproductive rates in Daphnia, whereas studies of effects on sexual reproductive rates remain relatively rare. ... -
Population dynamics in white-tailed eagle at an on-shore wind farm area in coastal Norway
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:231, Doctoral thesis, 2014)Collision with turbines and disturbance leading to loss of or reduced habitat quality are the two main impacts from wind energy development on birds. In addition, wind farms can act as barriers to birds. The conflict between ... -
