• Can aquaculture impact the surrounding biodiversity? A metabarcoding assessment 

      Guri, Gledis (Master thesis; Mastergradsoppgave, 2020-06-01)
      World’s population growth and rise in food consumption per capita have led to increased food demand and overexploitation of natural resources in recent decades. Such increase has threatened the global feeding schemes to maintain a balance between food supply and demand. Although “The Blue Revolution” promised to fill such gap and simultaneously alleviate the overexploitation of the oceans, deterioration ...
    • Fine-scale differences in eukaryotic communities inside and outside salmon aquaculture cages revealed by eDNA metabarcoding 

      Turon, Marta; Nygaard, Markus; Guri, Gledis; Wangensteen, Owen S.; Præbel, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-26)
      Aquaculture impacts on marine benthic ecosystems are widely recognized and monitored. However, little is known about the community changes occurring in the water masses surrounding aquaculture sites. In the present study, we studied the eukaryotic communities inside and outside salmonid aquaculture cages through time to assess the community changes in the neighbouring waters of the farm. Water ...
    • Integrating environmental DNA into marine management 

      Guri, Gledis (Doctoral thesis; Doktorgradsavhandling, 2024-05-14)
      Human-induced factors such as pollution, overfishing, habitat destruction and climate change, have precipitated a concerning decline in marine biodiversity, challenging the health and sustainability of marine ecosystems. While international conservation efforts have been initiated to address this crisis, they have frequently fallen short of achieving their objectives, mainly due to the lack of ...
    • Maximizing sampling efficiency to detect differences in fish community composition using environmental DNA metabarcoding in subarctic fjords 

      Guri, Gledis; Westgaard, Jon-Ivar; Yoccoz, Nigel; Wangensteen, Owen S.; Præbel, Kim; Ray, Jessica Louise; Kelly, Ryan P.; Shelton, Andrew Olaf; Hanebrekke, Tanja Lexau; Johansen, Torild (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-14)
      Environmental DNA (eDNA) has gained popularity as a tool for ecosystem biomonitoring and biodiversity assessment. Although much progress has been made regarding laboratory and fieldwork protocols, the issue of sampling efficiency requires further investigation, particularly in three-dimensional marine systems. This study focuses on fish community composition in marine ecosystems and aims to analyze ...
