Tree-killing bark beetles are major disturbance agents affecting coniferous forest ecosystems. The role of environmental conditions on driving beetle outbreaks is becoming increasingly important as global climatic change alters environmental factors, such as drought stress, that, in turn, govern...

Carbon and Nitrogen Mineralization and Microbial Succession in Oil Sands Reclamation Soils Amended with Pyrogenic Carbon
Download2014-12-31
Mackenzie, M.D., Lanoil, B., Hofstetter, S., Hatam, I.
Land reclamation of oil sands disturbed boreal forests in Alberta is a challenging task facing companies with surface mine leases. The government requires reclamation to equivalent land capability, which is a vague statement at best. Agronomic theories and methodologies have been applied in the...

Western North American landscapes are rapidly being transformed by forest die- off caused by mountain pine beetle with implications for plant and soil communities. The mechanisms that drive changes in plant and soil community structure and function, particularly for understory vegetation and the...

Characterizing the changes in host tree chemistry after cutting and revisiting the nutritional role of fungi in the novel mountain pine beetle host jack pine
DownloadFall 2018
Studies with conifer-infesting bark beetles commonly use tree bolts to evaluate the effects of host tree quality on various aspects of insect biology. Yet, whether host quality changes between live trees and bolts cut from these trees has not been assessed. Particularly, changes in concentrations...

Chemotypic variations of lodgepole pine affect mountain pine beetle behaviour and growth of its symbiotic fungus
DownloadSpring 2020
Plants generally show large chemotypic variations in susceptibility to phytophagous insects and pathogens. Plant chemical defenses, or secondary compounds, are important components of plant resistance to pest organisms. Among plants, coniferous trees produce complex oleoresins that contain toxic...

Alamouti, Sepideh Massoumi, Haridas, Sajeet, Feau, Nicolas, Robertson, Gordon, Bohlmann, Jorg, Breuil, Colette
Studies on beetle/tree fungal symbionts typically characterize the ecological and geographic distributions of the fungal populations. There is limited understanding of the genome-wide evolutionary processes that act within and between species as such fungi adapt to different environments, leading...

Comparative phylogeography, genetic differentiation, and contrasting reproductive modes in three fungal symbionts of a multipartite bark beetle symbiosis

Roe, Amanda, Rice, Adrianne, Coltman, David, Cooke, Janice, Sperling, Felix
Grosmannia clavigera is a fungal pathogen of pine forests in western North America and a symbiotic associate of two sister bark beetles: Dendroctonus ponderosae and D. jeffreyi. This fungus and its beetle associate D. ponderosae are expanding in large epidemics in western North America. Using the...

Provided that infectious prions (PrPTSE) are inactivated, composting of specified risk material (SRM) may be a viable alternative to rendering and land filling. The overall objective of this research was to utilize laboratory-scale composters to assess the degradation of SRM and PrPTSE during...

Coupling mountain pine beetle and forest population dynamics predicts transient outbreaks that are likely to increase in number with climate change
Download2023-09-27
Mountain pine beetle (MPB) in Canada have spread well beyond their historical range. Accurate modelling of the long-term dynamics of MPB is critical for assessing the risk of further expansion and informing management strategies, particularly in the context of climate change and variable forest...

Effect of Environmental Conditions on Flight Capacity in Mountain Pine Beetle (Coleoptera: Curculionidae: Scolytinae)
Download2020-10-01
Wijeranthna, Asha, Evenden, Maya
Mountain pine beetle (Dendroctonus ponderosae Coleoptera: Curculionidae: Scolytinae) is a major pest of pine (Pinaceae) in western North America. Mountain pine beetle has an obligatory dispersal phase during which beetles fly in search of new hosts to colonize. Climatic factors may influence...
