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...

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...

Regeneration development on lodgepole pine cutovers in the Upper Foothills forests of west-central Alberta
Download1985
Masters thesis. Results of an investigation of regeneration on harvested lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) areas in west-central Alberta. Samples were from pure lodgepole pine stands, clearcut and scarified from one to 15 years prior to the study.

Resource allocation, water relations and crown architecture examined at the tree and stand-level in northern conifers
DownloadFall 2013
Variation in quantity of light has driven plants to employ many strategies in order to persist in high and low light. It is also a primary driver of lower branch mortality and crown recession. Fine roots and leaves are complimentary tissues representing belowground and aboveground resource...

Seasonal photosynthetic activity in evergreen conifer leaves monitored with spectral reflectance
DownloadSpring 2014
Annual trends of the Photochemical Reflectance Index (PRI) and pigment content in evergreen conifer leaves were monitored over two years from 2011 to 2013. During the second year, chlorophyll fluorescence and gas exchange were included to examine the spring recovery of photosynthesis. All the...
