Fine-scale genetic diversity and relatedness in fungi associated with the mountain pine beetle
Download2019-01-01
Tsui, Clement K. M., Beauseigle, Stephanie, Ojeda Alayon, Dario I., Rice, Adrianne V., Cooke, Janice E. K., Sperling, Felix A. H., Roe, Amanda D., Hamelin, Richard C.
The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins, 1902) forms beneficial symbiotic associations with fungi. Here we explored the fine-scale spatial genetic structure of three of those fungi using single nucleotide polymorphism. We found that single mated pairs of beetles carry not...

St. Clair, C. C., Beyer, H. L., Gillies, C. S.
The persistence of forest-dependent species in fragmented landscapes is fundamentally linked to the movement of individuals among subpopulations. The paths taken by dispersing individuals can be considered a series of steps built from individual route choices. Despite the importance of these...

Finite element modeling of nonlinear dispersive field line resonances: Trapped shear Alfvén waves inside field‐aligned density structures
Download2003-01-01
Marchand, Richard, Rankin, Robert, Wanliss, J. , Tikhonchuk, V. T., Lu, J. Y.
Using a new two- dimensional nonlinear finite element model, we investigate the interaction of dispersive shear Alfven wave ( SAW) field line resonances ( FLRs) and ion acoustic waves in Earth's magnetosphere. We solve the full set of nonlinear reduced MHD equations self- consistently in...

Finite Larmor radius effects in stimulated Raman scattering
1985
Boyd, T. J. M., Rankin, Robert. , Gardner, G. A.
Stimulated Raman scattering from a magnetized plasma has been examined using the set of Vlasov–Maxwell equations. The incident laser light, propagating in the form of an extraordinary mode, decays into a scattered extraordinary mode together with electron‐Bernstein waves. For sufficiently strong...

Finite plane deformations of elastic solids reinforced with fibers resistant to flexure: complete solution
Download2018-01-12
A model for the deformation of an elastic solid reinforced by embedded fibers is presented in which elastic resistance of the fibers to bending is incorporated. Within the framework of strain-gradient elasticity, we formulated the equilibrium equations and necessary boundary conditions which...

McCarthy, G., Crichton, N.J., Linck, T., Seers, K., Titchen, A., Kitson, A., Edwards, R.T., Wallin, L., Hawkes, C., Estabrooks, C.A., Mockford, C., Cox, K., Harvey, G., Eldh, A.C., McCormack, B., Rycroft-Malone, G.
Background: Research evidence underpins best practice, but is not always used in healthcare. The Promoting Action on Research Implementation in Health Services (PARIHS) framework suggests that the nature of evidence, the context in which it is used, and whether those trying to use evidence are...

Fire Drives Transcontinental Variation in Tree Birch Defense against Browsing by Snowshoe Hares
Download2009
Cleland, D. T., Clausen, T. P., Hawkins, C. D. B., Picone, P. M., Moore, J. E., Bryant, J. P., Stevens, M. T., Kirilenko, A. P., Malone, T., Swihart, R. K., Landhausser, S. M., Cebrian, M., Veitch, A. M., Paragi, T. F., Jakubas, W. J., Packee, E. C., Carriere, S., Bodony, K. L., Williams, J. H., Popko, R. A., Carlson, M. R.
Abstract: Fire has been the dominant disturbance in boreal America since the Pleistocene, resulting in a spatial mosaic in which the most fire occurs in the continental northwest. Spatial variation in snowshoe hare ( Lepus americanus) density reflects the fire mosaic. Because fire initiates...

Fire regimes at the transition between mixedwood and coniferous boreal forest in northwestern Quebec.
Download2004
Flannigan, M., Kafka, V., Gauthier, S., Bergeron, Y.
Fire history was reconstructed for an area of 15 000 km2 located in the transition zone between the mixed and coniferous forests in Quebec's southern boreal forest. We used aerial photographs, archives, and dendroecological data (315 sites) to reconstruct a stand initiation map for the area. The...

First Nations students’ perceptions of school nutrition policy implementation: A mixed methods study
Download2018-01-01
Gillies, C., Alexander Research Committee, Farmer, A., Maximova, K., Willows, N.D.
Aim: School nutrition policies can improve healthy food access for Indigenous First Nations children in Canada. This study explored First Nations students’ perceptions of a school nutrition policy. Methods: The research was a process evaluation of school nutrition policy implementation using a...
