Abstract: In populations subject to positive density dependence, individuals can increase their fitness by synchronizing the timing of key life history events. However, phenological synchrony represents a perturbation from a population's stable stage structure and the ensuing transient dynamics create troughs of low abundance that can promote extinction. Using an ecophysiological model of a mass-attacking pest insect, we show that the effect of synchrony on local population persistence depends on population size and adu… Show more

“…Determining whether weak or strong Allee effects are more common in natural populations will rely on improved study design and analytical techniques. For example, Friedenberg et al (2007) present data on extinction probability vs. population density (Fig. 8a), which have the potential to differentiate between weak and strong Allee effects (Fig.…”

“…If less than 50% of populations replaced Fig. 8 a The probability of local extinction as a function of initial infestation size for southern pine beetles, Dendroctonus frontalis, across the south-eastern USA (Friedenberg et al 2007). It cannot be determined from the analysis whether the Allee effect is strong or weak.…”

“…However, the dynamics by which populations of some beetle species transition from noneruptive to eruptive conditions, and the extent to which these dynamics reflect withinstand versus migratory processes, are not well understood, and pose some fundamental questions about population dynamics and forest disturbance (Okland et al, 2005;Friedenberg et al, 2007). One approach to better understanding these dynamics, and the overall role of bark beetles in forest ecosystems, is through improved knowledge of tree-killing species that do not undergo Bark beetles are largely known for their ability to undergo intermittent population eruptions that transform entire landscapes and pose significant economic hardships.…”

“…Because disturbances can cause rapid changes in species abundances (Ostfeld & Keesing, ) and may lead to temporary synchrony among populations of different species in a community (Keitt, ; Vasseur & Gaedke, ), temporary bouts of synchrony, that is transient synchrony, might be a common occurrence in natural communities. Most of the literature investigating transient dynamics in insect populations investigate either the transition phases between different patterns of dynamics in populations of a single species (Friedenberg, Powell, & Ayres, ) following Hastings (), or transient dynamics among spatially structured populations of a single species (Hastings & Higgins, ; Ranta, Kaitala, & Lundberg, ; Saravia, Ruxton, & Coviella, ). Some studies explore transient synchrony in predator–prey interactions in spatially structured populations (Kidd & Amarasekare, ; Tobin & Bjornstad, ); they find that transient dynamics in the short term can affect the stability of predator–prey interactions.…”
