The impact of phloem nutrients on overwintering mountain pine beetles and their fungal symbionts
Download2012
Erbilgin, N., Goodsman, D. W., Lieffers, V. J.
In the low nutrient environment of conifer bark, subcortical beetles often carry symbiotic fungi that concentrate nutrients in host tissues. Although bark beetles are known to benefit from these symbioses, whether this is because they survive better in nutrient-rich phloem is unknown. After...

Abstract: We used the mast-seeding tree Picea glauca (white spruce) to examine whether the timing of mast years relative to fire had a lasting effect on the density and timing of regeneration. We studied 17 fires that occurred in mast years and in years with low cone production between 1941 and...

While local processes (e.g., competition, predation, and disturbance) presumably cause species exclusion and thus limit diversity in individual communities, regional processes (e.g., historical events, immigration, and speciation) are assumed to provide a source of species to colonize and thus...

The potential of aspen clonal forestry in Alberta: breeding regions and estimates of genetic gain from selection
Download2012
Brouard, J.S., Hamann, A., Gylander, T., Thomas, B.R.
Background: Aspen naturally grows in large, single-species, even-aged stands that regenerate clonally after fire disturbance. This offers an opportunity for an intensive clonal forestry system that closely emulates the natural life history of the species. In this paper, we assess the potential of...
