Gene discovery for enzymes involved in limonene modification or utilization by the mountain pine beetle-associated pathogen Grosmannia clavigera
Download2014-01-01
Lah, Ljerka, Wang, Ye, Breuil, Colette, Madilao, Lina, Bohlmann, Joerg, Lim, Lynette
To successfully colonize and eventually kill pine trees, Grosmannia clavigera (Gs cryptic species), the main fungal pathogen associated with the mountain pine beetle (Dendroctonus ponderosae), has developed multiple mechanisms to overcome host tree chemical defenses, of which terpenoids are a...

Growth of aspen and white spruce on naturally saline sites in northern Alberta: implications for development of boreal forest vegetation on reclaimed saline soils.
Download2012
Lilles, E.B., Purdy, B.G., Chang, S.X., Macdonald, S.E.
We examined height and basal area growth over time for trembling aspen and white spruce in plots along a salinity gradient at six naturally saline sites in northern Alberta, as a benchmark for forest productivity on reclaimed saline sites. We measured root distributions and analyzed foliage for...

Habitat and forage selection of moose in the aspen-dominated boreal forest, central Alberta
Download1992
Forage and habitat selection of tame moose (Alces alces) in a 65 ha enclosure were studied for an annual cycle. Although the staple winter foods were woody twigs, moose consumed large amounts of leaf litter and bark under some environmental conditions. Foliage dominated the diet following leaf...

The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

Identifying understory diversity and resilience patterns with the depth-to-water index in boreal mixedwood forests
DownloadFall 2017
For the purpose of informing biodiversity conservation efforts in managed landscapes, we explored whether and how understory plant communities (abundance, diversity, composition) were related to a topographic moisture index, called depth-to-water, in the boreal mixedwood forests of northwestern...

Impacts of aggregated retention harvesting on the diversity patterns of nocturnal moth species assemblages in the mixedwood boreal forest of northwestern Alberta
DownloadFall 2012
The loss of mature forest habitat from forest harvesting represents a substantial threat to the diversity of nocturnal boreal forest moth assemblages. In this study, I used spatial patterns of species diversity to quantify the effects of aggregated green tree retention harvesting on the diversity...

Lejoly, Justine Daniele Marthe
Exotic species of earthworms are invading North American forests, where native earthworms were extirpated by the last glaciation. The invasion of these ecosystem engineers can alter soil organic matter (SOM) dynamics, carbon (C) persistence, and ecosystem functioning. While the topic has been...

Influence of variable retention and deadwood characteristics on saproxylic beetles in boreal white spruce stands
DownloadSpring 2016
Retention forestry aims to maintain a significant level of continuity in forest structure, composition and complexity so as to support conservation and recovery of biodiversity and ecological function on managed landscapes; however, the amount and distribution of retention that best meets...
