Sympatric Arctic charr, <i>Salvelinus alpinus</i> (L. 1758), morphs have flexible but repeated life history strategies tested across five Norwegian lakes. In several Scandinavian polymorphic Arctic charr populations differentiated by their diet and habitat use, a large littoral omnivorous (LO) morph commonly cooccurs with a smaller profundal spawning (PB/PZ) morph. A third, large piscivorous (PP) ...

<p>1. Increasing populations of mesopredators are suspected to cause declines in vulnerable wildlife to the extent that mesopredator decimation actions (culling) have become commonplace. Design constraints, especially a lack of spatial replication, often hamper the assessment of the impact of such actions. However, extensive temporal replication (i.e. time series) and accounting for potentially ...

The cryosphere encompasses the seasonally and perennially frozen parts of the earth and its extent is both sensitive to and impacts upon the global climate through surface energy and moisture fluxes and feedbacks. The dynamics of ice and frozen ground also impact directly on, e.g., construction and maintenance of roads in cold regions or transportation across floating ice sheets. The aim of this ...

We propose the photonic-chip as a multimodal imaging platform for histopathological assessment, allowing large fields-of-view across diverse microscopy methods including total internal reflection fluorescence and single-molecule localization.

<i><p>Background</i> Vitamin D has been linked to sleep health in observational studies. Data from randomized controlled trials (RCTs) with vitamin D is scarce. <i><p>Methods</i> This study presents the results of a secondary analysis of 189 vitamin D insufficient participants (47.1% women) in a previously performed RCT, of which 92 were randomized to vitamin D (100,000 IU (2500 μg) as a ...

<p><b>BAKGRUNN</b> Pasienter utsatt for strøm henvises ofte til akuttmottaket, men det er ulike retningslinjer for hvordan disse bør håndteres. Vi beskriver her pasienter med strømgjennomgang fra lavspenning i akuttmottaket ved St. Olavs hospital. <p><b>METODE OG MATERIALE</b> Retrospektive data fra pasienter henvist til akuttmottaket etter strømgjennomgang fra lavspenning (< 1 000 volt) i ...

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic ...

Olweus spørreskjema om mobbing for elever ble utviklet på 1980-tallet og brukes til å kartlegge mobbing i skolen basert på elevers selvrapportering. I Norge brukes skjemaet først og fremst i grunnskolen på 4. til 10. trinn. Skjemaet ble utviklet på norsk, men er senere oversatt til flere språk, inkludert engelsk: The Olweus Bully/Victim Questionnaire (OBVQ; Olweus, 1986) og The Revised Olweus ...

<p><i>Background - </i>Most disabling strokes are due to a blockage of a large artery in the brain by a blood clot. Prompt removal of the clot with intra‐arterial thrombolytic drugs or mechanical devices, or both, can restore blood flow before major brain damage has occurred, leading to improved recovery. However, these so‐called endovascular interventions can cause bleeding in the brain. This is a ...

Dietary advanced glycation end-products (dAGEs) have been hypothesized to be associated with a higher risk of colorectal cancer (CRC) by promoting inflammation, metabolic dysfunction, and oxidative stress in the colonic epithelium. However, evidence from prospective cohort studies is scarce and inconclusive. We evaluated CRC risk associated with the intake of dAGEs in the European Prospective ...
