Changes in net ecosystem productivity and greenhouse gas exchange with fertilization of Douglas fir: Mathematical modeling in ecosys
Download2010
Bruemmer, C., Jassal, R. S., Grant, R. F., Black, T. A.
Abstract: The application of nitrogen fertilizers to Douglas fir forests is known to raise net ecosystem productivity (NEP), but also N(2)O emissions, the CO(2) equivalent of which may offset gains in NEP when accounting for net greenhouse gas (GHG) exchange. However, total changes in NEP and...

Conditional, temperature-induced proteolytic regulation of cyanobacterial RNA helicase expression
Download2014
Owttrim, George W., Tarassova, Oxana S., Chamot, Danuta
Conditional proteolysis is a crucial process regulating the abundance of key regulatory proteins associated with the cell cycle, differentiation pathways, or cellular response to abiotic stress in eukaryotic and prokaryotic organisms. We provide evidence that conditional proteolysis is involved...

Abbont, S. P., Lumley, T. C., Currah, R. S.
Abstract: During a survey of microfungi from rotting wood in northern Alberta forests, 49 species of ascomycetes, representing 24 genera, and 15 families in seven orders, were recovered. Twenty-eight species are new reports for Alberta, 15 of which are new for Canada, and seven are new for North...

Potential carbon losses from peat profiles: effects of temperature, drought cycles and fire
Download1992
Wein, R. W., Hogg, E. H., Lieffers, V. J.
Abstract: Global warming and the resultant increase in evapotranspiration might lead to lowered water tables in peatlands and an increase in fire frequency. The objective of this study was to investigate some of the potential effects of these changes on peat decomposition. Dry mass losses and...

Principal components of super-high dimensional statistical features and support vector machine for improving identification accuracies of different gear crack levels under different working conditions
Download2015
Tsui, Kwok Leung, Zuo, Ming J., Tse, Peter W., Wang, Dong
Gears are widely used in gearbox to transmit power from one shaft to another. Gear crack is one of the most frequent gear fault modes found in industry. Identification of different gear crack levels is beneficial in preventing any unexpected machine breakdown and reducing economic loss because...

Regulation of cold shock-induced RNA helicase gene expression in the cyanobacterium Anabaena sptrain PCC 7120
Download2000
Owttrim, George W., Chamot, Danuta
Expression of the Anabaena sp. strain PCC 7120 RNA helicase gene crhC is induced by cold shock.crhC transcripts are not detectable at 30°C but accumulate at 20°C, and levels remain elevated for the duration of the cold stress. Light-derived metabolic capability, and not light per se, is required...

Residual tree retention ameliorates short-term effects of clear-cutting on some boreal songbirds
Download2001
Hannon, S. J., Norton, M. R., Tittler, R.
Abstract: Retention of residual trees in \"cutblocks,\" logged blocks of forest, has been proposed as a method to conserve songbirds in landscapes fragmented by clear-cut logging. We examined songbird communities in the boreal mixed-wood forest of Alberta, Canada, to investigate the effect on...
