Prevalence of antibodies against Brucella spp. in West Greenland polar bears (Ursus maritimus) and East Greenland muskoxen (Ovibos moschatus)
(Journal article; Peer reviewed, 2018)Zoonotic infections transmitted from terrestrial and marine mammals to humans in European Arctic are of unknown significance, despite considerable potential for transmission due to local hunt and a rapidly changing ... -
Prevalence of Chlamydia pecorum in Juvenile Koalas ( Phascolarctos cinereus ) and Evidence for Protection from Infection via Maternal Immunization
(Journal article; Peer reviewed, 2018)Chlamydia pecorum in koalas (Phascolarctos cinereus) is considered a sexually transmitted infection. Analysis of samples from koala joeys (<1 yr) suggested that mother-to-young direct transmission was also occurring. ... -
Prevalence of fin erosion, shortened operculum and lesions in farmed Atlantic Salmon (Salmo salar)
(Master thesis, 2014)The aim of the study was to study the ocurrence of fin erosion, opercular deformities and body lesions in a smolt Production cycle of Atlantic salmon (Salmo salar), in relation to environmental parameters and features. -
Prey predictability and preparation versus recovery breathing strategies in European shags Gulosus aristotelis (L.) diving in different habitats
(Peer reviewed; Journal article, 2023)A recent study on the diving behaviour of European shags (Gulosus aristotelis (L.)) foraging in kelp forests off rocky coasts of Norway suggests surface durations are related only to the duration of the preceding dive, and ... -
Principles and Methods of Counteracting Harmful Salmon–Arthropod Interactions in Salmon Farming: Addressing Possibilities, Limitations, and Future Options
(Peer reviewed; Journal article, 2021)The arthropod salmon louse (Lepeophtheirus salmonis) is a major threat to Atlantic salmon aquaculture and wild salmonids. Essentially like in monoculture, very high concentrations of susceptible hosts may result in high ... -
Prioritization of cell cycle regulated genes
(Master thesis, 2013)The cell cycle is an important biological process in which a set of events occurs in a sequential manner progressing to the cell division. Cell cycle is regulated by periodic fluctuations in the expression levels of several ... -
Proceedings of the International Conference on Biodiversity – Present State, Problems and Prospects of its Conservation, January 8-10, 2011 University of Chittgaong, Chittagong 4331, Bangladesh

Processing of Gustatory Information by Protocerebral Neurons in the Moth Heliothis virescens
(Master thesis, 2012)Insects are guided to potential host plants by visual and olfactory signals. Upon arrival they encounter various taste stimuli, ultimately deciding whether the plant is a proper food or oviposition source. The detection ... -
Produced water components: uptake kinetics and effects on the metabolism of the Arctic copepod Calanus glacialis
(Master thesis, 2016)The oil exploration and search for new oil production fields is expanding further north and has reached the Arctic. Oil drilling activities release large amounts of produced water (PW) to the marine environment and sub-lethal ... -
Produced water from North Sea offshore oil platforms causes a suite of biological effects on developing lumpfish (Cyclopterus lumpus) eggs.
(Master thesis, 2020)This study investigated the impacts of several produced waters (PWs) from the North Sea on developing Cyclopterus lumpus larvae. Larvae were exposed for 96 hours early in development to 3 concentrations of 5 different PW ... -
Production and nutritional adaptation of the brine shrimpArtemia sp. as live food organism for larvae of marine cold water fish species
(Doctoral thesis, 2001)High nutritional value of Artemia sp. refers to high content of highly unsaturated fatty acids (n-3 HUFA) and in particular the content of DHA. In the enrichment experiments presented in this thesis new diets and one new ... -
Promoting bird conservation in wetland-associated landscapes: Factors influencing avian crop damage and farmers’ attitudes
(Peer reviewed; Journal article, 2022)Integrating agroecosystems as bird habitats are very important for long-term conservation planning because intensified agricultural land use has been a global threat to avifauna. To make agriculture compatible with ... -
Propionate induces intestinal oxidative stress via Sod2 propionylation in zebrafish
(Peer reviewed; Journal article, 2021)Propionate and propionyl-CoA accumulation have been associated with the development of mitochondrial dysfunction. In this study, we show that propionate induces intestinal damage in zebrafish when fed a high-fat diet (HFD). ... -
PROTAX-Sound: A probabilistic framework for automated animal sound identification
(Journal article; Peer reviewed, 2017)Autonomous audio recording is stimulating new field in bioacoustics, with a great promise for conducting cost-effective species surveys. One major current challenge is the lack of reliable classifiers capable of multi-species ... -
Proteininnhold og vekst for Saccharina latissima dyrket ved varierende tilførsel av nitrat og lys
(Master thesis, 2015)Det trengs en økning av matproduksjonen i verden, og en løsning er økning av akvakultur. For at en økning i akvakultur av fôrede arter skal være mulig og bærekraftig trengs det en ny kilde til proteiner som kan supplere ... -
Proteome and Growth Responses of the Key Species Calanus finmarchicus to future Ocean Acidification and Warming
(Master thesis, 2015)The zooplankton Calanus finmarchicus is a key species in the North Atlantic, by linking the primary production with upper trophic levels and by contributing to vertical export of carbon. Copepod eggs were cultured to a ... -
Proteomic study of low temperature responses in strawberry cultivars (Fragaria x ananassa Duchesne) that differ in cold tolerance
