We sow or plant vascular plant species on a large scale in revegetation and restoration projects in Norway today. Some of the species used are already found in Norway, but many of the species, subspecies or populations used though native are not local, that is, they are <i>regionally alien</i>. A regionally alien species is a species that is native to Norway (has been in Norway since 1800) somewhere ...

Det er nå om lag 20 år siden begrepet «open access» ble lansert og definert. Den gang så nok mange for seg at all forskning skulle bli publisert åpent og fritt tilgjengelig innen få år. Men etter 20 år er det fortsatt (i de fleste land) færre enn 50% av publikasjonene som blir gjort åpent tilgjengelige. Samtidig har oppmerksomheten blitt utvidet til å handle om mer enn åpne artikler. Åpne forskningsdata, ...

From June 2020 to February 2021, a consortium of 10 organisations undertook a large-scale study on open access journals across the world that are free for readers and authors, usually referred to as “OA diamond journals”. This study was commissioned by cOAlition S in order to gain a better understanding of the OA diamond landscape.

In permafrost areas, the active layer undergoes seasonal frost heave and thaw subsidence caused by ice formation and melting. The amplitude and timing of the ground displacement cycles depend on the climatic and ground conditions. Here we used Sentinel-1 Synthetic Aperture Radar Interferometry (InSAR) to document the seasonal displacement progression in three regions of Svalbard. We retrieved ...

Background: In Europe, the COVID-19 pandemic triggered a range of restrictive measures, which may have impacted alcohol consumption. <p> <p>Objectives: We explored perceived changes in alcohol consumption, their association with so-ciodemographic characteristics and past year alcohol con-sumption, and self-reported reasons for change after CO-VID-19 restrictions in Norway. <p> <p>Method: A ...

Radars used to observe meteor trails in the mesosphere deliver information on winds and temperature. Use of these radars is becoming a standard method for determining mesospheric dynamics and temperatures worldwide due to relatively low costs and ease of deployment. However, recent studies have revealed that temperatures may be overestimated in conditions such as high geomagnetic activity. The effect ...

The Norwegian Scientific Committee for Food and Environment (VKM) was requested by the Norwegian Environment Agency to assess the risk of negative impacts to biodiversity in Norway resulting from import of crustacean decapods for keeping in freshwater aquariums.<p> <p>VKM was asked to 1) list species of crayfish, crabs and shrimps that are currently kept in freshwater aquaria in Norway, and ...

Polar cod (<i>Boreogadus saida</i>) is a key species in the arctic marine ecosystem vulnerable to effects of pollution, particularly from petroleum related activities. To facilitate studying the effects of those pollutants, we adapted a precision-cut liver slice culture protocol for this species. Using this system on board a research vessel, we studied gene expression in liver slice after exposure ...
