Local Consequences of a Global Model for Mountain Pine Beetle Mass Attack
نویسندگان
چکیده
A coupled partial diierential equation model for interaction between mountain pine beetles (MPB) and lodgepole pine is reviewed. An asymptoticòne-tree' solution is examined and time scale of the chemical response discussed. The equations are decoupled making an adiabatic assumption for MPB chemotaxis, and a `local' projection is made using the leading eigenfunction for the MPB density equation. This projection yields a system of ordinary diierential equations for the spatio-temporal response at a single tree. These equations are analyzed, and their behavior compared with observations.

Nitrogen Cycling Responses to Mountain Pine Beetle Disturbance in a High Elevation Whitebark Pine Ecosystem
Ecological disturbances can significantly affect biogeochemical cycles in terrestrial ecosystems, but the biogeochemical consequences of the extensive mountain pine beetle outbreak in high elevation whitebark pine (WbP) (Pinus albicaulis) ecosystems of western North America have not been previously investigated. Mountain pine beetle attack has driven widespread WbP mortality, which could drive ...

The antiaggregation pheromone verbenone was operationally tested for 5 yr to deter mass attack by the mountain pine beetle on lodgepole pine in campgrounds and administrative areas surrounding RedÞsh and Little RedÞsh Lakes at the Sawtooth National Recreation Area in central Idaho. Each year, Þve-gram verbenone pouches were evenly distributed ( 10 m apart) within seven of 14 0.2-ha plots. Durin...
متن کاملThe legacy of attack: implications of high phloem resin monoterpene levels in lodgepole pines following mass attack by mountain pine beetle, Dendroctonus ponderosae Hopkins.
The mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most serious pest of pines (Pinus) in western North America. Host pines protect themselves from attack by producing a complex mixture of terpenes in their resin. We sampled lodgepole pine (Pinus contorta variety latifolia) phloem resin at four widely separated locations in the interior of British Columbia, Canada, both just befo...
متن کاملSevere White Pine Blister Rust Infection in Whitebark Pine Alters Mountain Pine Beetle (Coleoptera: Curculionidae) Attack Density, Emergence Rate, and Body Size.
Exotic tree pathogens can cause devastating ecological effects on forests that can be exacerbated when infections increase the likelihood of attack by insects. Current high rates of mortality of whitebark pine (Pinus albicaulis Engelm.) are due to white pine blister rust caused by the exotic fungus, Cronartium ribicola J.C. Fisch, and the native mountain pine beetle (Dendroctonus ponderosae Hop...
متن کامل1H Nuclear Magnetic Resonance of Lodgepole Pine Wood Chips Affected by the Mountain Pine Beetle
In this study, wood-water interactions of mountain pine beetle affected lodgepole pine were found to vary with time since death. Based on an analysis of magnetization components and spin-spin relaxation times from 1H NMR, it was determined that the mountain pine beetle attack does not affect the crystalline structure of the wood. Both the amorphous structure and the water components vary with t...
