Combining biochemical methods to trace organic effluent from fish farms
Woodcock, Skye; Troedsson, Christofer; Strohmeier, Tore; Balseiro Vigo, Pablo; Skaar, Katrine Sandnes; Strand, Øivind (Peer reviewed; Journal article, 2017)The substitution of fish oils and fish meal with terrestrial components in the diets of farmed fin-fish offers a unique opportunity to trace organic effluents from fin-fish aquaculture into the marine environment. In this ... -
Molecular gut content analysis demonstrates that Calanus grazing on Phaeocystis pouchetii and Skeletonema marinoi is sensitive to bloom phase but not prey density
Ray, Jessica Louise; Skaar, Katrine Sandnes; Simonelli, Paolo; Larsen, Aud; Troedsson, Christofer (Peer reviewed; Journal article, 2016-01-19)Mesozooplankton grazing selection in complex marine microbial communities is a poorly understood yet critical structuring component of marine microbial food webs. We wished to quantitatively assess how relative grazing by ... -
The potential of sedimentary ancient DNA for reconstructingpast sea ice evolution
De Schepper, Stijn; Ray, Jessica Louise; Skaar, Katrine Sandnes; Sadatzki, Henrik; Ijaz, Umer Zeeshan; Stein, Ruediger; Larsen, Aud (Peer reviewed; Journal article, 2019-06-24)Sea ice is a crucial component of the Arctic climate system, yet the tools to document the evolution of sea ice conditions onhistorical and geological time scales are few and have limitations. Such records are essential ... -
Quantitative molecular detection of larval Atlantic herring (Clupea harengus) in stomach contents of Atlantic mackerel (Scomber scombrus) marks regions of predation pressure
Allen, Bridie; Ray, Jessica Louise; Tiedemann, Maik; Komyakova, Valeriya; Vikebø, Frode Bendiksen; Skaar, Katrine Sandnes; Stiasny, Martina H.; Folkvord, Arild; Nash, Richard David Marriott; Stenevik, Erling Kåre; Kjesbu, Olav Sigurd (Journal article; Peer reviewed, 2021)Mortality rates in the early life-history stages of fishes are generally high yet identifying the causes remain unclear. Faltering recruitment rates of Atlantic herring (Clupea harengus) in the Norwegian Sea indicate a ... -
Removal of large viruses and their dispersal through fecal pellets of the appendicularian Oikopleura dioica during Emiliania huxleyi bloom conditions
Mayers, Kyle; Lawrence, Janice; Skaar, Katrine Sandnes; Töpper, Joachim Paul; Petelenz-Kurdziel, Elzbieta Anna; Saltvedt, Marius Rydningen; Sandaa, Ruth-Anne; Larsen, Aud; Bratbak, Gunnar; Ray, Jessica Louise (Journal article; Peer reviewed, 2021)Despite their importance in shaping the structure and function of marine microbial food webs, little is known about factors regulating marine virus abundance. Previous work demonstrated clearance of laboratory-cultured ... -
Sex differentiation in Atlantic cod (Gadus morhua L.): morphological and gene expression studies
Haugen, Trine; Almeida, Fernanda F. L.; Andersson, Eva; Bogerd, Jan; Male, Rune; Skaar, Katrine Sandnes; Schulz, Rüdiger W.; Sørhus, Elin; Wijgerde, Tim; Taranger, Geir Lasse (Peer reviewed; Journal article, 2012-06-18)Background: In differentiated gonochoristic species, a bipotential gonad develops into an ovary or testis during sex differentiation. Knowledge about this process is necessary to improve methods for masculinizing genetically ...
