A life course and intergenerational approach to the study of musculoskeletal pain: The HUNT Study
Lier, Ragnhild (Doctoral thesis at NTNU;2016:272, Doctoral thesis, 2016)Sammendrag på norsk Livsløps- og generasjonsstudier av muskel- og skjelettsmerter i HUNT-studien Kroniske muskel- og skjelettsmerter er blant de fremste årsakene til redusert livskvalitet, sykefravær og uførhet i den ... -
Coming soon to a fjord near you: future jellyfish scenarios in a changing climate
Tiller, Rachel Gjelsvik; Borgersen, Åshild Løvås; Knutsen, Øyvind; Bailey, Jennifer L.; Bjelland, Hans Vanhauwaert; Mork, Jarle; Eisenhauer, Lionel; Liu, Yajie (Journal article; Peer reviewed, 2016)Over the last decades, a dense population of the deep-sea/oceanic scyphozoan jellyfish Periphylla periphylla has established itself as top predator in the Trondheimsfjord in Norway, which has caused the traditional fisheries ... -
Conservation of genetic diversity in populations of stellate sturgeon (Acipenser stellatus) of the NW Black Sea and Lower Danube River
Holostenco, Daniela Nicoleta (Master thesis, 2011)The stellate sturgeons as well as the other sturgeon populations inhabiting the Lower Danube River system (LDR) and the NW part of the Black Sea have experienced a severe decline due to heavy fishery, river regulation and ... -
Extent and ecological importance of escape through spawning in sea-cages for Atlantic cod
Uglem, Ingebrigt; Knutsen, Øyvind; Kjesbu, Olav Sigurd; Hansen, Øyvind J; Mork, Jarle; Bjørn, Pål Arne; Varne, Rebekka; Nilsen, Rune; Ellingsen, Ingrid H.; Dempster, Timothy David (Journal article; Peer reviewed, 2012)The culture of certain fish species to sizes at which they can reproduce has led to the escape of fertilised eggs or ‘escape through spawning’. To investigate the extent and ecological importance of spawning in sea-cages ... -
Farmed cod escapees and net-pen spawning left no clear genetic footprint in the local wild cod population.
Varne, Rebekka; Kunz, Kristina Lore; Johansen, Torild; Westgaard, Jon-Ivar; Uglem, Ingebrigt; Mork, Jarle (Journal article; Peer reviewed, 2015-11-18)This study investigated a potential genetic introgression from farmed to wild cod Gadus morhua L. in the Trondheimsfjord, Norway. During the first 2 yr of operation of a cod farm in the inner part of the fjord, 2 large ... -
Genetic variability at isozyme loci in two gadoid species; whiting (Merlangus merlangus L.) and saithe (Pollachius virens L.) from the Norwegian coast

Population trend of Periphylla periphylla in inner Trondheimsfjord
Solheim, Hilde (Master thesis, 2012)Periphylla periphylla (Scyphozoa, Coronatae) is a deep sea jellyfish first described by Péron & Lesueur in 1809. It is distributed in all of the world s oceans except for the Arctic. P. periphylla avoids light and is well ... -
Recruitment dynamics of Periphylla periphylla in the Trondheimsfjord
Borgersen, Åshild Løvås (Master thesis, 2013)Periphylla periphylla (Péron and Lesueur 1809) is a deep sea coronate scyphomedusa distributed in all oceans of the world, where it is normally found in low abundances. Over the last decades, however, it has established ... -
The Energy Budget of a Local Jellyfish Proliferation: Periphylla periphylla in The Trondheimsfjord, Norway
Jøssang, Ida (Master thesis, 2015)Trondheimsfjorden is one of approximately one dozen Norwegian fjords where the crown jellyfish, Periphylla periphylla (Scyphozoa, Coronatae) has had massive blooms. It has established large local populations during the ... -
The haemoglobin polymorphism of whiting (Merlangius merlangus L.) in the northeast Atlantic
Gjengedal, Håkon (Master thesis, 2011)The HbI* polymorphism in cod (Gadus morhua L.) has been thoroughly investigated during 50 years. It has two common alleles, and several studies have indicated that allele frequencies are influenced by environmental factors, ... -
To Adapt or Not Adapt: Assessing the Adaptive Capacity of Artisanal Fishers in the Trondheimsfjord (Norway) to Jellyfish (Periphylla periphylla) Bloom and Purse Seiners
Tiller, Rachel Gjelsvik; Mork, Jarle; Liu, Yajie; Borgersen, Åshild Løvås; Richards, Russell (Journal article; Peer reviewed, 2015)Worldwide increases of jellyfish has occurred during the last several decades. A dense population of a large scyphozoan jellyfish, Periphylla periphylla, has established itself as top predator in the Trondheimsfjord in ... -
Tracing the fate of escaped farmed cod (Gadus morhua L.) in a Norwegian fjord system
Varne, Rebekka (Doctoral thesis at NTNU;2016:116, Doctoral thesis, 2016)Summary of thesis: The aim of this thesis was to investigate the fate of escaped farmed cod and detect any introgression in the local stock. Phenotypic discrimination of wild and farmed cod, and genetic baseline values ...
