    • Forage quality in tundra grasslands under herbivory: Silicon-based defences, nutrients and their ratios in grasses 

      Petit Bon, Matteo; Inga, Katarina Gunnarsdotter; Utsi, Tove Aagnes; Jonsdottir, Ingibjørg; Bråthen, Kari Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-08)
      1. Herbivore-induced changes in both leaf silicon-based defence and nutrient levels are potential mechanisms through which grazers alter the quality of their own grass supply. In tundra grasslands, herbivores have been shown to increase nutrient contents of grasses; yet, it is an open question whether they also increase grass silicon-based defence levels. Here, we asked if, and to what extent, ...

    • Interactions between winter and summer herbivory affect spatial and temporal plant nutrient dynamics in tundra grassland communities 

      Petit Bon, Matteo; Inga, Katarina Gunnarsdotter; Jónsdóttir, Ingibjörg Svala; Utsi, Tove Aagnes; Soininen, Eeva Marjatta; Bråthen, Kari Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-27)
      In the long‐term, herbivores can alter nutrient dynamics in terrestrial ecosystems by changing the functional composition of plant communities. Here, we ask to what extent herbivores can affect plant‐community nutrient dynamics in the short‐term. We provide theoretical expectations for immediate effects of herbivores on tundra‐grassland plant‐community nutrient levels throughout a single growing ...
