A time series analysis was performed on 32 dendrochronological chronologies using Dutilleul's multi frequential periodo gram. Our aim was to estimate the periodicities of spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks in the province of Quebec. Our analysis estimated a signal of 25-38 years corresponding to spruce budworm outbreaks. Analyses conducted in the 20th century indicated the existence of true periodicities in half of the series suggesting local population dynamics. These periodicities were estimated to be 29-34 years. For the other series, outbreaks were explained by the addition of a second periodic component to the fundamental periodicity. These combined periodicities (pseudoperiodicities or complex periodicities) described most of the 130-year series analysed. The lack of several outbreaks explained part of the combined periodicity. The results suggest a migration effect and complex local population dynamics. A third periodic component explains the double epidemic waves. These es...

- Disturbance dynamics of old-growth Picea rubens forests of northern Maine (2005, background): “While spruce budworm outbreaks may recur somewhat cyclically (Blais 1983; Royama 1984; Jardon et al. 2003), other disturbances occur quite sporadically.”
- Spruce budworm outbreaks in eastern Quebec over the last 450 years (2004, background): “…complex dynamics of outbreak initiation and propagation as influenced by internal and external factors at the local and regional scales (Candau et al. 1998; Jardon et al. 2003), they do not support the idea that outbreak frequency and synchrony increased during the 20th century (Blais 1965, 1983).”
