Abstract: The lowering of the water table resulting from peatland drainage may dramatically alter C and N cycling in peatland ecosystems, which contain one-third of the total terrestrial C. In this study, tree annual ring width and C (delta C-13) and N (delta N-15) isotope ratios in soil and...

Dimitrov, D. D., Grant, R. F., Lafleur, P. M., Humphreys, E. R.
Abstract: Changes in arctic C stocks with climate are thought to be caused by rising net primary productivity (NPP) during longer and warmer growing seasons, offset by rising heterotrophic respiration (Rh) in warmer and deeper soil active layers. In this study, we used the process model ecosys to...

Ectomycorrhizae of Jack Pine and Green Alder: Assessment for the Need for Innoculation, Development of Innoculation Techniques, and Outplanting Trials on Oil Sands Tailings
Download1988
The overall objectives of these studies were to characterize the mycorrhizal status of jack pine and green alder which are prime candidates as reclamation species for oil sand tailings and to determine the potential benefits of mycorrhizae on plant performance. This entailed determining the...

Air pollution and its effects on various ecosystems has been a subject of increasing controversy. The European forest damage situation has heightened the public's awareness of the problem. Historically, the observed pollution damage was believed to be due mainly to sulphur dioxide pollution. ...

Macdonald, S. Ellen, Islam, M. Anisul
In order to compare the ability of black spruce (Picea mariana (Mill.) BSP) 1 and tamarack (Larix laricina (Du Roi) K. Koch) to adjust to variable edaphic conditions, 2 as found in natural peatlands, we varied nitrogen (N) fertilization of seedlings in a growth 3 chamber experiment over two...

This literature review provides an understanding of ecological resilience as a concept to promote successful land reclamation in Alberta’s mineable oil sands region by exploring four key issues: Defining ecological resilience for boreal forest ecosystems, and assessing whether this definition can...
