    • The quick and the slow: Competitive ability of two silica-rich grasses influenced by large and small herbivores 

      Lægreid, Eiliv Jenssen (Master thesis; Mastergradsoppgave, 2013-05)
      Silicate-rich grasses often dominate in heavily grazed areas, presumably because high amounts of silica deter herbivores. Activity of large herbivores and small rodent herbivores increase competitive ability of silicate-rich grasses, possibly through apparent competition. Both types of herbivores often co-exist in grassland ecosystems. Their potential additive effect on competitive ability of ...
