Questions Which environmental variables are most important in determining plant species composition in subarctic springs? Do observed patterns differ between typical wetland and general matrix‐derived species? Location Helocrenic (seepage) springs, Northern Norway. Methods We sampled 49 helocrenic spring sites, measuring environmental variables (water temperature, water pH, electrical conductivity, discharge volume, geographic position) and recording all species present. We performed a partial canonical correspondence analysis (pCCA) to determine the relative importance of water quality, spatial, and climatic variables for patterns in species composition and to compare the differences in these patterns between wetland and matrix‐derived species. Results We found that climatic and water quality variables were almost equally important in determining species composition in subarctic springs, with climatic variables explaining 26.62% of variation in species composition and water quality variables explaining 26.14%. Spatial variables explained the least variation (21.53%). When looking at the variables individually, altitude (10.93%) and mean summer temperature (9.25%) explained the most variation. The trend was the same for matrix‐derived species and wetland species, with climatic variables explaining the most variation (matrix‐derived: 27.26%; wetland: 24.42%), followed by water quality (matrix‐derived: 26.40%; wetland: 24.13%) and spatial variables (matrix‐derived: 24.87%; wetland: 16.27%). The main difference between matrix‐derived species and typical wetland species was that the spatial variables explained less variation for wetland species. Conclusions The close relationship of species composition (total vegetation as well as separated into wetland and matrix‐derived species) with climatic and water quality conditions indicates a sensitivity of subarctic springs to future climate change. In combination with altitude, which was found to be the most important individual variable, it is likely that the future distribution of spring species tracking climate change will be limited by the occurrence of suitable spring habitats, especially at high altitudes.

Beiting og slått har skapt noen av de mest artsrike økosystemene i Nord-Europa, men slike tradisjonelle driftsformer har blitt mindre vanlige i det 20. århundre. Denne endringen er en viktig drivkraft for påfølgende gjengroing som kan ha dramatiske konsekvenser for det biologiske mangfoldet, kanskje spesielt i kombinasjon med klimaendringer.

In this educational tool kit, your pupils will learn about the amazing and sometimes odd ways animals have adapted to living, especially in polar extreme environments. This is part 1 of a series of three tool kits on the topic. Part 1 gives an introduction and explains principles of evolutionary adaptations in view of climate change. Part 2 is about animals in the taiga, while part 3 is about animals on the tundra.

In this educational tool kit, your pupils will learn about why and where there is a region called Fennoscandia. We explore cultures for the outdoors that are shared between all the countries of the region. In role play, pupils will explore how one, by learning about another’s culture, one can more easily accept it even when one does not like it.

Do you know what happens when an exotic species comes to a new place, where it does not belong? Can the planet be completely invaded by exotic species? What exactly is an exotic species? In this learning package, we look at how invasive species are a growing problem and how they can affect the environment, other species and even the entire global bioeconomy.

I denne læringspakka vil elevene lære om hvorfor og hvor det finnes en region vi kaller Fennoskandia. Vi forteller om kulturer for utendørsliv, som man finner på tvers av landegrensene her. I en egen utforsker-lab vil elevene utforske livsmestring: at ved å lære om andres kultur, kan vi lettere akseptere den selv om vi ikke liker den.

Vet du hva som skjer når en fremmed art kommer til et nytt sted, hvor den ikke hører hjemme? Kan kloden invaderes fullstendig av fremmede arter? Hva er egentlig en fremmed art? I denne læringspakka ser vi på hvordan invaderende arter er et økende problem og hvordan de kan påvirke miljøet, andre arter og til og med hele den globale bioøkonomien.

I denne læringspakka vil du lære om de fantastiske (og noen ganger rare) tilpasningene som dyr har til det å leve i sitt miljø, spesielt under polare ekstreme forhold. Du vil få innblikk i hvordan forskerne tror disse dyrene vil takle et varmere klima. Dette er del 1 av 3 i en serie. Den er introduksjon til faget, mens del 2 og del 3 er om dyrene i taiga og på tundra.
