The theoretical approach of ecoplexivity focusing on mass outbreaks of phytophagous insects and altering forest functions

December 2009

  Epidemics of forest insects can have deep impacts on ecosystem functioning and dynamics, with consequences for forest economics and forest carbon feedback to climate change. Despite the many roles that insects fulfil in terrestrial ecosystems, their importance in nutrient cycling is not well known (Kosola et al., 2001). The only instances where herbivores are recognized to have a large effect on ecosystem...
