Mountain pine beetle outbreak and ectomycorrhizal feedback: the ecology of recovery in beetle killed forests
DownloadSpring 2014
The expansion of mountain pine beetle (Dendroctonus ponderosae; MPB) into naïve host ecosystems has been met by gaps in two key areas of research: (A) affects on the chemistry of forest soils, and (B) impacts on the regeneration of tree seedlings. To investigate linkages between both, we paired...

A species-diagnostic SNP panel for discriminating lodgepole pine, jack pine, and their interspecific hybrids
Download2013-01-01
Dang, S. , Cullingham, Catherine I. , Cooke, Janice E. K., Coltman, David W.
Accurate stock identification is important for forest management, yet this can be a challenge for tree species that hybridize naturally. Species discriminating molecular markers provide a means to identify stock with high accuracy. In Canada, lodgepole pine (Pinus contorta Dougl. ex Loud. var....

Influence of water deficit on the molecular responses of Pinus contorta × Pinus banksiana mature trees to infection by the mountain pine beetle fungal associate, Grosmannia clavigera

Kayal, Walid El, Cooke, Barry J., Linsky, Jean, Arango-Velez, Adriana, Galindo González, Leonardo M., Cooke, Janice E.K., Meents, Miranda J., Lusebrink, Inka
Conifers exhibit a number of constitutive and induced mechanisms to defend against attack by pests and pathogens such as mountain pine beetle (Dendroctonus ponderosae Hopkins) and their fungal associates. Ecological studies have demonstrated that stressed trees are more susceptible to attack by...

Linking genotype to phenotype to identify genetic variation relating to host susceptibility in the mountain pine beetle system
Download2020-01-01
Cullingham, Catherine I., Peery, Rhiannon M., Fortier, Colleen E., Mahon, Elizabeth L., Cooke, Janice E. K., Coltman, David W.
Identifying genetic variants responsible for phenotypic variation under selective pressure has the potential to enable productive gains in natural resource conservation and management. Despite this potential, identifying adaptive candidate loci is not trivial, and linking genotype to phenotype is...

Study of early selection in tree breeding - 3. A case study using early information to enhance selection efficiency in late trait in lodgepole pine (Pinus contorta spp. Latifolia)
Download2000
Wu, H.X., Pharis, R.P., Dhir, N.K., Yeh, F.C., Dancik, B.P.
We present a selection procedure that combines early performance from retrospective study and late performance from field testing into an index designed for enhancing the selection efficiency of the late performance. The prerequisite is that early performance from retrospective study and late...

Pre-Commercial Thinning Increases Merchantability and Reduces Western Gall Rust Infections in Lodgepole Pine
DownloadFall 2023
Alberta’s forest industry is predicted to be impacted by a short to medium-term decline in timber supply. Intensive silviculture tools, such as pre-commercial thinning, have been shown to increase individual tree growth, shorten rotation lengths and improve stand merchantability in important...

Inconsistent growth response to fertilization and thinning of lodgepole pine in the Rocky Mountain Foothills is linked to site index
Download2012
Lieffers, V. J., Landhausser, S. M., Pinno, B. D.
Fertilization of conifers often results in highly variable growth responses across sites which are difficult to predict. The goal of this study was to predict the growth response of lodgepole pine (Pinus contorta var. latifolia) crop trees to thinning and fertilization using basic site and foliar...

Impact of Mountain Pine Beetle Attack on Water Balance of Lodgepole Pine Forests in Alberta
DownloadSpring 2013
In recent decades mountain pine beetle (MPB) has become an important natural disturbance agent in western Canada, thus the impact of this disturbance will likely be an important component affecting water resources in this region. Despite the widespread recognition of the potential changes, there...

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...

Changes in soil fungal communities following logging and salvage logging disturbances decrease lodgepole pine (Pinus contorta var. latifolia) seedling performance
DownloadSpring 2019
Disturbances are frequent events across the Canadian boreal forests and can affect both below and above ground ecosystem processes at various temporal and spatial scales. We have limited understanding of how changes in the below ground fungal communities affect above ground plant communities....
