Spatial Synchrony in Forest Insect Outbreaks: Roles of Regional Stochasticity
Spatial synchrony, that is, correlated population fluctuation over wide geographical areas, has been detected in diverse taxa and over various geographical scales. The most commonly suggested mechanisms to explain spatial synchrony include dispersal and regional stochasticity (i.e., “the Moran effect”). We analyzed landscape-scale historical outbreak data for six forest insect species: spruce b...
متن کاملA resource-depletion model of forest insect outbreaks.
Detailed analyses of thresholded ecological interactions can improve our understanding of the transition from aperiodic to periodic dynamics. We develop a threshold model of the population dynamics of outbreaking bark beetle populations that alternate between non-epidemic and epidemic behavior. The model involves accumulation of resources during low-density periods and depletion during outbreak...
متن کاملInduced plant defenses, host-pathogen interactions, and forest insect outbreaks.
Cyclic outbreaks of defoliating insects devastate forests, but their causes are poorly understood. Outbreak cycles are often assumed to be driven by density-dependent mortality due to natural enemies, because pathogens and predators cause high mortality and because natural-enemy models reproduce fluctuations in defoliation data. The role of induced defenses is in contrast often dismissed, becau...

متن کاملImpacts of Forest-Based Activities on Woodland Characteristics
The purpose of this study was to investigate the impacts of forest-based activities on the conditions of the Ganaveh woodland in the southern Zagros, Iran, and to suggest strategies for improving the implementation of forest resource management plans. Woodland inventory data was gathered in 2003, accompanied with data from interviews in 2008, were used in this study. The results show that there...
