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...

Hernandez-Castillo, G.R., Stockey, R.A., Beard, G.
Two permineralized conifer pollen cones have been identified from the AppianWay locality on the east coast of Vancouver Island, British Columbia. These cones, found in marine calcareous nodules with invertebrates, are Eocene in age and have been studied with the cellulose acetate peel technique....

The cytochrome P450 CYP6DE1 catalyzes the conversion of α-pinene into the mountain pine beetle aggregation pheromone trans-verbenol

Chiu, Christine C., Keeling, Christopher I., Bohlmann, Joerg
The recent outbreak of the mountain pine beetle (Dendroctonus ponderosae; MPB) has afected over 20M hectares of pine forests in western North America. During the colonization of host trees, female MPB release the aggregation pheromone (−)-trans-verbenol. (−)-trans-Verbenol is thought to...

Bunya pine (Araucaria bidwillii Hooker) produces large seeds that consist of a massive megagametophyte that surrounds an embryo 25-30 mm long and 3-5 mm in diameter. The seeds germinate on the soil surface, but elongation of the cotyledonary tube pushes the hypocotyl, with its associated plumule...
