A dynamical model for bark beetle outbreaks [PDF]

Journal of Theoretical Biology, 2016
Tree-killing bark beetles are major disturbance agents affecting coniferous forest ecosystems. The role of environmental conditions on driving beetle outbreaks is becoming increasingly important as global climatic change alters environmental factors, such as drought stress, that, in turn, govern tree resistance.
