Functional genomics of mountain pine beetle (Dendroctonus ponderosae) midguts and fat bodies
Download2010-01-01
Keeling, Christopher I., Bearfield, Jeremy C., Blomquist, Gary J., Schlauch, Karen, Tittiger, Claus, Young, Sharon, Aw, Tidiane
Background The mountain pine beetle (Dendroctonus ponderosae) is a significant coniferous forest pest in western North America. It relies on aggregation pheromones to colonize hosts. Its three major pheromone components, trans-verbenol, exo-brevicomin, and frontalin, are thought to arise via...

Growth and Physiological Responses of Conifer Seedlings to Salt Stress and Nutrient Deficiency
DownloadSpring 2018
Oil sands extraction and refining can cause many negative environmental impacts and because these activities usually take place in the forest region, the Government of Alberta requires that, after mine sites are closed, the companies perform reclamation. The properties of reclaimed oil sands...

Wang, W., Li, J., Liu, D., Lu, Z., Zheng, H., Wong, G., Cai, Z., Fan, C., Zhang, J., Vang, S., Long, M., Zhang, G., Wang, J., Shi, J.
Retroposition is widely found to play essential roles in origination of new mammalian and other animal genes. However, the scarcity of retrogenes in plants has led to the assumption that plant genomes rarely evolve new gene duplicates by retroposition, despite abundant retrotransposons in plants...

Interactions of pea leaf weevil (Coleoptera: Curculionidae) with its primary and secondary host plants in Alberta
DownloadFall 2021
The pea leaf weevil, Sitona lineatus Linnaeus (Coleoptera: Curculionidae), is an invasive, oligophagous herbivore that feeds on a variety of legume (Fabales: Fabaceae) plants. Field peas (Pisum sativum) and faba bean (Vicia faba) are the primary host plants of the pea leaf weevil. Adult weevils...

Mandibles and labrum-epipharynx of tiger beetles: Basic structure and evolution (Coleoptera, Carabidae, Cicindelitae)
Download2011
Acorn, J. H., Ball, G. E., Shpeley, D.
Abstract: Using for comparison with, and as outgroups for, supertribe Cicindelitae, we describe and illustrate the mandibles and labrum-epipharynx of the basal geadephagans Trachypachus gibbsii LeConte, 1861 (family Trachypachidae), and family Carabidae: Pelophila rudis (LeConte, 1863)...

Phoretic mite associates of mountain pine beetle at the leading edge of an infestation in northwestern Alberta, Canada
Download2011
Proctor, H. C., Evenden, M. L., Mori, B. A., Walter, D. E.
Abstract: We identified species of mites phoretically associated with mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), collected from bolts of lodgepole pine, Pinus contorta Douglas ex Louden (Pinaceae), and pheromone-baited traps in northwestern...

Phytochemicals as mediators for host range expansion of a native invasive forest insect herbivore.
Download2019-01-01
Mountain pine beetle (MPB, Dendroctonus ponderosae) has recently breached the geo-climatic barrier of the northern Rocky Mountains and invaded novel jack pine (Pinus banksiana) forests in western Canada. This breach signifies an unprecedented climate change-induced invasion of a new plant biome...

Re-establishment of hummock topography promotes tree regeneration on highly disturbed moderate-rich fens
Re-establishment of hummock topography promotes tree regeneration on highly disturbed moderate-rich fens

Caners, Richard T., Lieffers, Victor J., Ge, Hangfei
Winter exploration of oil sands deposits underlying wooded fens mostly eliminates the hummock-hollow topography on drilling pads and the ice roads leading to them, after their abandonment in spring. Recovery of black spruce (Picea mariana (P. Mill.) B.S.P.) and tamarack (Larix laricina (Du Roi)...

Reconstructing Emporia Lockardii (Voltziales:Emporiaceae) and Initial Thoughts on Paleozoic Conifer Ecology
Download2009
Stockey, R.A., Rothwell, G.W., Hernandez-Castillo, G.R., Mapes, G.
A new plant concept for the extinct conifer species Emporia lockardii (Mapes&Rothwell) Mapes&Rothwell (Emporiaceae) is developed from fossils collected at the Late Pennsylvanian Hamilton Quarry, Kansas. Emporia lockardii has lateral plagiotropic branches with simple and forked leaves, simple...
