The role of bioluminescent prey in the diet of two hatchetfish species and four lanternfish species in the North Atlantic Ocean in relation to eye-size
(Master thesis, 2023-06-16)The mesopelagic zone, often referred to as “the twilight zone” can be defined as the area of the ocean at 200-1000 m depth. Here, light levels vary greatly and provides a varying visual scene. At shallow depths, down-welling ... -
Microplastic in subsurface water in the South Pacific Ocean
(Master thesis, 2023-07-01)Microplastic (MP) in the world’s oceans is a global concern. Studies on MP are frequently published, but there is limited information on MP in the South Pacific Ocean. Here, a seawater filtration unit collected MPs down ... -
Palaeovegetation and environment during Weichselian stadials and interstadials at Mamontovaya Kurja and Sokolova in the Pechora basin, northern Russia
(Master thesis, 2000)The vegetation and climate history of the Pechora area of northwestern Russia during the Early- and Mid Weichselian have been studied. Sediments from two sites have been analysed in this study; from Sokolova and Mamontovaya ... -
The Abundance of PE 18:2 is Increased in Parkinson’s Disease Patient Brain Tissue and DJ-1 Knockout Zebrafish Disease Models
(Master thesis, 2023-06-02)Parkinson’s Disease (PD) is an age-related neurodegenerative disorder associated with both motor and non-motor symptoms. It is characterized by depletion of dopamine-producing neurons in the substantia nigra and the presence ... -
Effects of photoperiod regimes and salinity on Na+, K+-ATPase α-isoform expression in gills and kidney during smoltification in Atlantic salmon (Salmo salar) in recirculating aquaculture systems
(Master thesis, 2023-06-02)Understanding the molecular mechanisms of smoltification and seawater adaptation in Atlantic salmon (Salmo salar) is crucial for optimizing smolt production in aquaculture. This study investigated the expression patterns ... -

(Master thesis, 2023-06-02)Reproductive traits are a fundamental aspect of an organism's life history and play a critical role in shaping population dynamics, as these traits can significantly influence offspring survival rates and, thereby, ... -
Behavioral and depth preference for wrasse (Labridae) used as cleaner fish in salmon aquaculture
(Master thesis, 2023-06-02)Wild and farmed wrasse are used as cleaner fish in Norwegian salmon aquaculture as a biological remedy against the ectoparasite salmon lice. For wrasse to be a well-functioning cleaner fish, it is essential that the species ... -
Investigations of the CEL VNTR by cellular experiments and in silico analyses
(Master thesis, 2023-06-02)Carboxyl ester lipase (CEL) is a digestive enzyme which is secreted by acinar cells in the pancreas and released into the intestines. In addition to the globular domain responsible for lipase activity, CEL contains a ... -
