      Summary report from VKM’s scientific opinions for 2016 - 2017<br>The goal of this report is to highlight research needs and data gaps that are of future importance for food safety and protection of the environment and thereby improve the national knowledge base. This report is the latest in a series of reports on research needs and data gaps published periodically by the Norwegian Scientific Committee ...

    • Risk assessment of radioactivity in Food. Opinion of the Scientific Committee of the Norwegian Scientific Committee for Food Safety, VKM report 2017:25

      Since 1986, the management of radioactive contamination in food and feed in Norway has been driven mainly by the Chernobyl Disaster follow-up. Monitoring and countermeasures are still in place to reduce the exposure to the population. The Norwegian Food Safety Authority is in the process of revising the maximum levels (MLs) for radioactive substances in drinking water and food and establishing ...

    • Stay or go – how topographic complexity influences alpine plant population and community responses to climate change 

      Graae, Bente Jessen; Vandvik, Vigdis; Armbruster, W. Scott; Eiserhardt, Wolf L.; Svenning, Jens-Christian; Hylander, Kristoffer; Ehrlén, Johan; Speed, James D.M.; Klanderud, Kari; Bråthen, Kari Anne; Milbau, Ann; Opedal, Øystein Hjorthol; Alsos, Inger G.; Ejrnæs, Rasmus; Bruun, Hans Henrik; Birks, H. John B.; Westergaard, Kristine Bakke; Birks, Hilary H; Lenoir, Jonathan (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-11)
      In the face of climate change, populations have two survival options − they can remain in situ and tolerate the new climatic conditions (“stay”), or they can move to track their climatic niches (“go”). For sessile and small-stature organisms like alpine plants, staying requires broad climatic tolerances, realized niche shifts due to changing biotic interactions, acclimation through plasticity, or ...

      Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions and moisture availability during winter. It also affects the growing season’s start and end, and plant access to moisture and nutrients. Here, we review the current knowledge of the snow cover’s role for vegetation, plant-animal interactions, permafrost conditions, ...
