Mountain pine beetle host-range expansion threatens the boreal forest
The current epidemic of the mountain pine beetle (MPB), an indigenous pest of western North American pine, has resulted in significant losses of lodgepole pine. The leading edge has reached Alberta where forest composition shifts from lodgepole to jack pine through a hybrid zone. The susceptibility of jack pine to MPB is a major concern, but there has been no evidence of host-range expansion, i...
متن کاملLodgepole pine, jack pine, and their hybrids: molecular markers reveal mountain pine beetle host-range expansion into jack pine of the boreal forest
Background Lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) is found in western North America, extending from the Yukon into British Columbia and Washington, and along the Rocky Mountains and eastern slopes to Colorado [1]. Jack pine (Pinus banksiana Lamb.) is a closely related species found east of the Rockies, mainly in Canada’s boreal forest from the Northwest Territories to Qu...
متن کاملBreach of the northern Rocky Mountain geoclimatic barrier: initiation of range expansion by the mountain pine beetle
Examining the spatio-temporal attributes of populations of invasive organisms can provide insights into their rates and patterns of spread, which in turn can suggest mechanisms driving their establishment and persistence (Peterson & Vieglais, 2001). Climate plays a central role in many invasion events, by impacting host distribution (Iverson & Prasad, Natural Resources and Environmental Science...
متن کاملForest Development and Carbon Dynamics after Mountain Pine Beetle Outbreaks
Mountain pine beetles periodically infest pine forests in western North America, killing many or most overstory pine stems. The surviving secondary stand structure, along with recruited seedlings, will form the future canopy. Thus, even-aged pine stands become multiaged and multistoried. The species composition of affected stands will depend on the presence of nonpines and outbreak severity, am...
متن کاملMountain Pine Beetle Epidemiology in Lodgepole Pine
The following brief synthesis of mountain pine beetle epidemiology is based on host-beetle interaction. In the first part I briefly describe the relationship between the dynamics of lodgepole pine and mountain pine beetle. The second part describes the phases in the infestation cycle and their main characteristics. This synthesis is based on published information on infestation behaviour in wes...
