• Functional traits of alpine plant communities show long-term resistance to changing herbivore densities 

      Vuorinen, Katariina Elsa Maria; Austrheim, Gunnar; Mysterud, Atle; Gya, Ragnhild; Vandvik, Vigdis; Grytnes, John Arvid; Speed, James David Mervyn (Peer reviewed; Journal article, 2021)
      Herbivores shape vegetation by suppressing certain plant species while benefitting others. By thus modifying plant species functional composition, herbivores affect carbon cycling, albedo, vegetation structure and species' ...
    • Impact of an invasive alien plant on litter decomposition along a latitudinal gradient 

      Helsen, Kenny; Smith, Stuart; Brunet, J; Cousins, Sara A.O.; De Frenne, Pieter; Kimberley, Adam; Kolb, Annette; Lenoir, Jonathan; Ma, Shiyu; Michaelis, Jana; Pule, Jan; Verheyen, Kris; Speed, James David Mervyn; Graae, Bente Jessen (Journal article; Peer reviewed, 2018)
      Invasive alien plant effects on ecosystem functions are often difficult to predict across environmental gradients due to the context-dependent interactions between the invader and the recipient communities. Adopting a ...
    • Moose effects on soil temperatures, tree canopies, and understory vegetation: a path analysis 

      Kolstad, Anders Lorentzen; Austrheim, Gunnar; Graae, Bente Jessen; Solberg, Erling Johan; Strimbeck, Richard; Speed, James David Mervyn (Journal article; Peer reviewed, 2018)
      Large vertebrate herbivores are ubiquitous and increasingly numerous in boreal forests where they are known to influence ecosystems in many ways. However, separating the direct effects of herbivores from their indirect ...
    • Pervasive moose browsing in boreal forests alters successional trajectories by severely suppressing keystone species 

      Kolstad, Anders Lorentzen; Austrheim, Gunnar; Solberg, Erling Johan; De Vriendt, Laurent; Speed, James David Mervyn (Journal article; Peer reviewed, 2018)
      Large herbivores can shape young forest stands and determine the successional trajectory of forested ecosystems by selectively browsing palatable species at the sapling stage. Moose (Alces alces) is the dominant vertebrate ...
