Structure and composition of riparian boreal forest: new methods for analyzing edge influence
Download2001
Abstract: Riparian ecotones at lakeshore edges are prominent features on the heterogeneous boreal forest landscape. We introduce a new method (the critical values approach): which incorporates inherent variability in interior forest, to quantify distance of edge influence at lakeshore forest...

Vinge, T., Powter, C.B., Pyper, M.P.
Ecological resilience, first defined by Holling in 1973, can be broadly described as the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly, but other authors have provided variations on this theme since 1973. Ecological resilience is...

The biosphere as an increasing sink for atmospheric carbon: estimates from increased nitrogen deposition
Download1993
Estimates of carbon uptake and storage based on global nitrogen deposition, C:N ratios for typical terrestrial ecosystems, and recent ecosystem-scale nutrient studies indicate that 1.0- 2.3 Gt C yr-1 of carbon storage may be stimulated by anthropogenically caused increases in nitrogen deposition...

The ecology of boreal forest floor microbial communities in relation to environmental factors
DownloadFall 2012
Soil microbial communities in boreal forests are structured by complex interactions among many factors operating simultaneously on large and small spatial scales. Of particular note in the boreal mixedwood, the microbial communities under trembling aspen and white spruce forest floors are...

Topsoil Handling During Pipeline Construction in Potentially Arable Forested Luvisols of Northwest Alberta
Download1999
Patterson, T.J., Fedkenheuer, A.W., Faye, R.G., Finlayson, N.M., Luther, S.M.
The objective of this study was to evaluate several pipeline topsoil stripping depths to determine whether they result in land capability equivalent to that of adjacent forested lands broken for cultivation. Topsoil stripping depths were 0 cm, 15 cm and 30 cm. Soils chosen for the study were...

The objective of this literature review was to evaluate the available information on the effects of stripping versus not stripping topsoil during pipeline construction in potentially arable Luvisolic soils in forested areas. A profile description representative of an undisturbed Luvisol under...

Birds can be used as indicators to monitor success of programs encouraging prairie landowners to increase biodiversity. Using a case study from Alberta, Canada, this paper compares bird diversity measures at the farm scale and examines their consistency across different habitat types to test for...
