A new species of extinct conifer plants, Emporia royalii sp. nov. Hernandez-Castillo, Stockey, Mapes et Rothwell (Emporiaceae: Voltziales), is described from the rich fossil biota of the Late Pennsylvanian, Hamilton Quarry, Kansas. This conifer has lateral plagiotropic branches with simple and...
Cyanogenic glycosides are secondary plant compounds that are widespread in the plant kingdom. Their biosynthesis starts with the conversion of aromatic or aliphatic amino acids into their respective aldoximes, catalysed by N-hydroxylating cytochrome P450 monooxygenases (CYP) of the CYP79 family....

Background The mountain pine beetle, Dendroctonus ponderosae Hopkins, is the most serious insect pest of western North American pine forests. A recent outbreak destroyed more than 15 million hectares of pine forests, with major environmental effects on forest health, and economic effects on the...
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...
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 fensDownload
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 EcologyDownload
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 AlbertaDownload
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.
Study of climatic effects on Picea mariana near Inuvik.
Resource allocation, water relations and crown architecture examined at the tree and stand-level in northern conifersDownload
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...
