A vigor-structured model for mountain pine beetle outbreak dy- namics within a forest stand is proposed and analyzed. This model explicitly tracks the changing vigor structure in the stand. All model parameters, other than beetle vigor preference, were determined by tting model components to...

Mountain pine beetle (MPB; Dendroctonus ponderosae) disturbances, amplified by climate change, have led to extensive tree mortality and ecosystem succession in boreal forests across western Canada. Often following attack, former ectomycorrhizal (EM) pine stands in Alberta are replaced by...

Simard, S. W., Cahill Jr, J. F., Erbilgin, N., RolTreu, J., Karst, M., Pec, J., Cigan, P. W., Cooke, J. E. K., Gregory, R.

Forest die-off caused by mountain pine beetle (MPB; Dendroctonus ponderosa) is rapidly transforming western North American landscapes. The rapid and widespread death of lodgepole pine (Pinus contorta) will likely have cascading effects on biodiversity. One group particularly prone to such...

As climate changes and disturbance regimes shift, there is a need to better understand and anticipate potential impacts of both natural and anthropogenic disturbance agents on forest ecosystems. Lodgepole pine forests in western Canada are experiencing an unprecedented mountain pine beetle (MPB)...

The mountain pine beetle (Dendroctonus ponderosae, MPB) has killed millions of lodgepole pine (Pinus contorta) trees in Western Canada and recent range expansion has resulted in attack of jack pine (Pinus banksiana) in Alberta. Establishment of MPB in the Boreal forest will require use of jack...

The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae) is the most damaging pest of mature pine (Pinaceae) in western North America. Although mountain pine beetles have an obligate dispersal phase during which adults must locate a new host for brood...

Client sexual advances may be a common occurrence in therapy, yet there is little information available with strategies for managing them. In hope of initiating a dialogue, five female therapists’ experiences were examined for possible insights. Informal semi-structured interviews provided data...

Background Mountain pine beetles, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae), are native to western North America, but have recently begun to expand their range across the Canadian Rocky Mountains. The requirement for larvae to withstand extremely cold winter temperatures and...

Effective forest management requires reliable growth and yield models and adequate information on changes in the forest resulting from climate change, insect outbreak and competition from neighboring trees. Growth responses of white spruce (Picea glauca (Moench) Voss) and black spruce (Picea...
