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...

Role of adventitious roots in water relations of tamarack (Larix laricina) seedlings exposed to flooding
Download2012
Calvo-Polanco, M., Senorans, J., Zwiazek, J.J.
Background: Flooding reduces supply of oxygen to the roots affecting plant water uptake. Some flooding-tolerant tree species including tamarack (Larix laricina (Du Roi) K. Koch) produce adventitious roots in response to flooding. These roots were reported to have higher hydraulic conductivity...

Strategies for reforestation under uncertain future climates: guidelines for Alberta, Canada
Download2011
Abstract: Background: Commercial forestry programs normally use locally collected seed for reforestation under the assumption that tree populations are optimally adapted to local environments. However, in western Canada this assumption is no longer valid because of climate trends that have...

Temperature sensitivity of N2O emissions from fertilized agricultural soils: Mathematical modeling in ecosys
Download2008
N2O emissions have been found to be highly sensitive to soil temperature (T-s) which may cause substantial rises in emissions with rises in Ts expected in most climate change scenarios. Mathematical models used to project changes in emissions during climate change should be able to simulate the...

Wasylishen, R. E., Bernard, G. M., Quideau, S. A., Norris, C. E., Landhausser, S. M.
Abstract: Enriching plant tissues with C-13 and N-15 isotopes has provided long-lasting, non-reactive tracers to quantify rates of terrestrial elemental fluxes (e.g., soil organic matter decomposition). However, the molecular location and level of isotope enrichment may differ among plant...
