    • Junipers enable heavily browsed rowan saplings to escape ungulates in boreal forest 

      Hegland, Stein Joar; Rydgren, Knut; Lilleeng, Marte Synnøve; Moe, Stein Ragnar; Gillespie, Mark Andrew Kusk (Peer reviewed; Journal article, 2021)
      Recent increases in ungulate herbivore populations have intensified browsing pressure in northern forest ecosystems. High browsing pressure affects recruitment into tree populations and saplings are among the most impacted ...

    • Molecular and ecological plant defense responses along an elevational gradient in a boreal ecosystem 

      Benevenuto, Rafael Fonseca; Seldal, Tarald; Polashock, James; Moe, Stein Ragnar; Rodriguez-Saona, Cesar; Gillespie, Mark Andrew Kusk; Hegland, Stein Joar (Peer reviewed; Journal article, 2020)
      Plants have the capacity to alter their phenotype in response to environmental factors, such as herbivory, a phenomenon called phenotypic plasticity. However, little is known on how plant responses to herbivory are modulated ...

    • Multiannual effects of induced plant defenses: Are defended plants good or bad neighbors? 

      Benevenuto, Rafael Fonseca; Hegland, Stein Joar; Töpper, Joachim Paul; Rydgren, Knut; Moe, Stein Ragnar; Rodriguez-Saona, Cesar; Seldal, Tarald (Journal article; Peer reviewed, 2018)
      Defenses induced by herbivore feeding or phytohormones such as methyl jasmonate (MeJA) can affect growth, reproduction, and herbivory, not only on the affected individual but also in its neighboring plants. Here, we report ...

    • Neighborhood effects of herbivore-induced plant resistance vary along an elevational gradient 

      Fonseca Benevenuto, Rafael; Seldal, Tarald; Moe, Stein Ragnar; Rodriguez-Saona, Cesar; Hegland, Stein Joar (Peer reviewed; Journal article, 2020)
      The activation of plant defense systems in response to herbivory or experimentally applied methyl jasmonate (MeJA) involves the production of chemical defense substances functioning as warning signals to repel herbivores ...

    • Old-growth forest floor richness increases with red deer herbivory intensity 

      Hegland, Stein Joar; Lilleeng, Marte Synnøve; Moe, Stein Ragnar (Journal article; Peer reviewed, 2013)
      Herbivory is one of the most important biotic disturbance types globally and is important for community structure and composition through species filtering. In northern forest ecosystems the population densities of ...

    • Red deer mediate spatial and temporal plant heterogeneity in boreal forests 

      Lilleeng, Marte Synnøve; Hegland, Stein Joar; Rydgren, Knut; Moe, Stein Ragnar (Journal article; Peer reviewed, 2016)
      Selective herbivory can influence both spatial and temporal vegetation heterogeneity. For example, many northern European populations of free-ranging ungulates have reached unprecedented levels, which can influence plant ...
