Droughts drive outbreak dynamics of an invasive forest insect on an exotic host
Forest Ecology and Management(2019)
摘要
•Sirex noctilio outbreaks are synchronized at a regional scale.•Occurrence of S. noctilio outbreaks are triggered by an abrupt increase in drought.•Tree mortality decrease due to negative density-dependence in S. noctilio populations.•The damage caused by the outbreaks is determined by stand management variables.
