  Mesopelagic sound scattering layers of the high Arctic: Seasonal variations in biomass, species assemblage, and trophic relationships 

  Geoffroy, Maxime; Daase, Malin; Cusa, Marine Lure Joana; Darnis, Gérald; Graeve, Martin; Santana Hernadez, Nestor; Berge, Jørgen; Renaud, Paul Eric; Cottier, Finlo Robert; Falk-Petersen, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-12)

  Mesopelagic sound scattering layers (SSL) are ubiquitous in all oceans. Pelagic organisms within the SSL play important roles as prey for higher trophic levels and in climate regulation through the biological carbon pump. Yet, the biomass and species composition of SSL in the Arctic Ocean remain poorly documented, particularly in winter. A multifrequency echosounder detected a SSL north of Svalbard, ...

  Ambient temperature effects on stress-induced hyperthermia in Svalbard ptarmigan 

  Nord, Andreas; Folkow, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-20)

  Stress-induced hyperthermia (SIH) is commonly observed during handling in homeotherms. However, in birds, handling in cold environments typically elicits hypothermia. It is unclear whether this indicates that SIH is differently regulated in this taxon or if it is due to size, because body temperature changes during handling in low temperatures have only been measured in small birds <0.03 kg (that ...

  Seasonal shifts in feeding patterns: Individual and population realized specialization in a high Arctic fish 

  Cusa, Marine Lure Joana; Berge, Jørgen; Varpe, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-21)

  Species with a broad and flexible diet may be at an advantage in a rapidly changing environment such as in today's Arctic ecosystems. Polar cod (<i>Boreogadus saida</i>), an abundant and ecologically important circumpolar Arctic fish, is often described as a zooplankton generalist feeder, which suggests that it may cope successfully with changes in prey composition. This description is justified ...

  The PI3K and MAPK/p38 pathways control stress granule assembly in a hierarchical manner 

  Heberle, Alexander Martin; Razquin Navas, Patricia; Langelaar-Makkinje, Miriam; Kasack, Katharina; Sadik, Ahmed; Faessler, Erik; Hahn, Udo; Marx-Stoelting, Philip; Opitz, Christiane A.; Sers, Christine; Heiland, Ines; Schaeuble, Sascha; Thedieck, Kathrin (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-28)

  All cells and organisms exhibit stress-coping mechanisms to ensure survival. Cytoplasmic protein-RNA assemblies termed stress granules are increasingly recognized to promote cellular survival under stress. Thus, they might represent tumor vulnerabilities that are currently poorly explored. The translation-inhibitory eIF2α kinases are established as main drivers of stress granule assembly. Using a ...

  Avløp og oppdrettsanlegg som mulige forurensningskilder til mikroplast i blåskjell (Mytilus edulis) 

  Johnsen, Ingunn Solheim (Master thesis; Mastergradsoppgave, 2019-05-14)

  De siste 60 årene har masseproduksjonen av plast økt (Barnes et al., 2009) og lite tyder på at produksjonen av plast vil avta med det første på grunn av de samme egenskapene som gjør at plast er farlig på avveie; det er et slitesterkt materiale og vi kjenner ikke fullstendig til konsekvensene eller nedbrytningsforløpet av det. Mikroplast er små plastpartikler som kan komme fra mange ulike ...
