A new species of Pinus Subgenus Pinus Subsection Contortae from Pliocene sediments of Ch'ijee's Bluff, Yukon Territory, Canada.Download
Three structurally preserved conifer ovulate cones are described from Pliocene sediments at Ch’ijee’s Bluff on the Porcupine River, near Old Crow, Yukon Territory, Canada. Cones are ovoid to conical, symmetrical, 3.4–4.4 cm long and 2.8–3.4 cm wide, with helically arranged cone-scale complexes....
A species-diagnostic SNP panel for discriminating lodgepole pine, jack pine, and their interspecific hybridsDownload
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....
Characterizing the physical and genetic structure of the lodgepole pine × jack pine hybrid zone: mosaic structure and differential introgressionDownload
Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid...
Chemotypic variations of lodgepole pine affect mountain pine beetle behaviour and growth of its symbiotic fungusDownload
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...
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...
Genetic variation in lodgepole pine and interior spruce: adaptation to climate and implications for seed transferDownload
This thesis investigates genetic variation of two commercially important conifers in western Canada, interior spruce and lodgepole pine. The goals were to quantify genetic diversity and geographic structure, to describe multitrait adaptation to local climates, and to use this information for the...
Soil fungi after pine beetle outbreak: Diagnosis of fungal community composition and treatment of outplanted seedlings with tailored soil inoculumDownload
Soil fungal communities play vital roles in boreal forests as key organisms that cycle nutrients, facilitate uptake of resources for mycorrhizal plants, and store carbon. Forest disturbances often result in shifts in soil fungal community composition, yet, it is unclear if these effects are...
The Push-Pull Tactic for Mitigation of Mountain Pine Beetle (Coleoptera: Curculionidae) Damage in Lodgepole and Whitebark PinesDownload
In an attempt to improve semiochemical-based treatments for protecting forest stands from bark beetle attack, we compared push-pull versus push-only tactics for protecting lodgepole pine (Pinus contorta Douglas ex Loudon) and whitebark pine (Pinus albicaulis Engelm.) stands from attack by...
As climates warm and extreme climatic events occur with more frequency and severity, maintaining forest health and productivity may involve planting seed sources from warmer, drier areas. To guide such reforestation strategies, this work analyzes the risks of both climate change and assisted...
