    • Consequences of barriers and changing seasonality on population dynamics and harvest of migratory ungulates 

      Van Moorter, Bram; Engen, Steinar; Fryxell, John M.; Panzacchi, Manuela; Nilsen, Erlend Birkeland; Mysterud, Atle (Peer reviewed; Journal article, 2020)
      Many animal populations providing ecosystem services, including harvest, live in seasonal environments and migrate between seasonally distinct ranges. Unfortunately, two major sources of human-induced global change threaten ...
    • Continuous and discontinuous variation in ecosystem carbon stocks with elevation across a treeline ecotone 

      Speed, James David Mervyn; Martinsen, Vegard; Hester, Alison J.; Holand, Øystein; Mulder, Jan; Mysterud, Atle; Austrheim, Gunnar (Journal article; Peer reviewed, 2015)
      Treelines differentiate vastly contrasting ecosystems: open tundra from closed forest. Treeline advance has implications for the climate system due to the impact of the transition from tundra to forest ecosystem on ...
    • Effects of Sheep Grazing on Availability and Leaching of Soil Nitrogen in Low-Alpine Grasslands 

      Martinsen, Vegard; Mulder, Jan; Austrheim, Gunnar; Hessen, Dag Olav; Mysterud, Atle (Journal article; Peer reviewed, 2012)
      Alpine ecosystems are generally nitrogen (N) limited with low rates of N mineralization. Herbivory may affect N cycling and N losses and thus long-term productivity of ecosystems. Using a controlled grazing experiment in ...
    • Experimental effects of herbivore density on above-ground plant biomass in an alpine grassland ecosystem 

      Austrheim, Gunnar; Speed, James David Mervyn; Martinsen, Vegard; Mulder, Jan; Mysterud, Atle (Journal article; Peer reviewed, 2014)
      Herbivores may increase or decrease aboveground plant productivity depending on factors such as herbivore density and habitat productivity. The grazing optimization hypothesis predicts a peak in plant production at ...
    • Framdriftsrapport for Scandlynx Norge 2011 

      Odden, John; Mattisson, Jenny; Linnell, John Durrus; Mysterud, Atle; Melis, Claudia; Nilsen, Erlend Birkeland; Brøseth, Henrik; Teurlings, Ivonne; Samelius, Gustav; McNutt, Helen L.; Andren, Henrik; Persson, Jens; Arnemo, Jon Martin; Sjulstad, Kjartan; Ulvund, Kristine R.; Loe, Leif Egil; Segerström, Peter; Turtumøygard, Tea; Strømseth, Thomas Holm; Gervasi, Vincenzo; Bouyer, Yaëlle; Flagstad, Øystein (NINA rapport;842, Research report, 2012)
      Rapporten oppsummerer aktiviteten til det skandinaviske forskningsprosjektet på gaupe (Scandlynx) i Norge det siste året. Rapporten er i hovedsak ment som en kort oversikt over gjennomførte aktiviteter til oppdragsgivere ...
    • Long-Term Increase in Aboveground Carbon Stocks Following Exclusion of Grazers and Forest Establishment in an Alpine Ecosystem 

      Speed, James David Mervyn; Martinsen, Vegard; Mysterud, Atle; Mulder, Jan; Holand, Øystein; Austrheim, Gunnar (Journal article; Peer reviewed, 2014)
      Ecosystem stores of carbon are a key component in the global carbon cycle. Many studies have examined the impact of climate change on ecosystem carbon storage, but few have investigated the impact of land-use change and ...
    • The neglected season: Warmer autumns counteract harsher winters and promote population growth in Arctic reindeer 

      Loe, Leif Egil; Liston, Glen E.; Pigeon, Gabriel; Barker, Kristin; Horvitz, Nir; Stien, Audun; Forchhammer, Mads C.; Getz, Wayne M.; Irvine, Robert Justin; Lee, Aline Magdalena; Movik, Lars K.; Mysterud, Atle; Pedersen, Åshild Ønvik; Reinking, Adele K.; Ropstad, Erik; Trondrud, Liv Monica; Tveraa, Torkild; Veiberg, Vebjørn; Hansen, Brage Bremset; Albon, Steve D. (Peer reviewed; Journal article, 2020)
      Arctic ungulates are experiencing the most rapid climate warming on Earth. While concerns have been raised that more frequent icing events may cause die-offs, and earlier springs may generate a trophic mismatch in phenology, ...
    • Spatio-temporal variation in large herbivore pressure in Norway during 1949-1999: has decreased grazing by livestock been countered by increased browsing by cervids? 

      Austrheim, Gunnar; Solberg, Erling Johan; Mysterud, Atle (Journal article; Peer reviewed, 2011)
      During recent decades, rough livestock grazing has decreased markedly on unimproved land (i.e. natural and seminatural habitats) across most of Europe, whilst the number of wild cervids has increased. However, we still ...
    • Synergies and trade-offs between ecosystem services in analpine ecosystem grazed by sheep – An experimental approach 

      Austrheim, Gunnar; Speed, James David Mervyn; Evju, Marianne; Hester, Alison; Holand, Øystein; Loe, Leif Egil; Martinsen, Vegard; Mobæk, Ragnhild; Mulder, Jan; Steen, Harald; Thompson, Des B.A.; Mysterud, Atle (Journal article; Peer reviewed, 2016)
      Domestic livestock drives ecosystem changes in many of the world’s mountain regions, and can be the dominant influenceon soil, habitat and wildlife dynamics. Grazing impacts on ecosystem services (ES) vary according to ...
    • The Response of Alpine Salix Shrubs to Long-Term Browsing Varies with Elevation and Herbivore Density 

      Speed, James David Mervyn; Austrheim, Gunnar; Hester, Alison J.; Mysterud, Atle (Journal article; Peer reviewed, 2013)
      The widespread expansion of shrubs into arctic and alpine regions has frequently been linked to climatic warming, but herbivory can play a role in addition to, or in interaction with, climate. Willow (Salix spp.) shrubs ...
    • The Role of Individual Traits and Environmental Factors for Diet Composition of Sheep 

      Mysterud, Atle; Austrheim, Gunnar (Peer reviewed; Journal article, 2016)
      Large herbivore consumption of forage is known to affect vegetation composition and thereby ecosystem functions. It is thus important to understand how diet composition arises as a mixture of individual variation in ...
