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 ... -
Virus infection of Haptolina ericina and Phaeocystis pouchetii implicates evolutionary conservation of programmed cell death induction in marine haptophyte-virus interactions
Ray, Jessica Louise; Haramaty, Liti; Thyrhaug, Runar; Fredricks, Helen F.; Van Mooy, Benjamin A.S.; Larsen, Aud; Bidle, Kay D.; Sandaa, Ruth-Anne (Peer reviewed; Journal article, 2014-05-05)The mechanisms by which phytoplankton cope with stressors in the marine environment are neither fully characterized nor understood. As viruses are the most abundant entities in the global ocean and represent a strong ...
