Simulations of fully coupled lake‐groundwater exchange in a subhumid climate with an integrated hydrologic model
Download2007
Devito, K.J., Smerdon, B.D., Mendoza, C.A.
[1] A fully coupled, integrated surface water/groundwater model was used to study hydrologic controls on lake-groundwater interaction in the subhumid, Boreal Plains of northern Alberta, Canada. Findings from a previous water budget study indicate that lakes on the outwash landscape capture...

Soil Mesostigmata (Arachnida: Parasitiformes) in boreal forests of Alberta: diversity and utility as indicators of disturbance
DownloadSpring 2018
Soils provide numerous ecosystem services, including provision of nutrients for plants, sequestration of greenhouse gases, and serving as habitat for soil animals. Soil animal diversity is immense, and many undescribed taxa still remain. One prominent group that inhabits soils is mites...

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...

The effects of soil and plant nutrients on the oviposition preference, larval performance and spatial dynamics of Ceutorhynchus obstrictus and its parasitoids
DownloadFall 2010
The effects of nitrogen and sulfur fertilization on the oviposition, feeding preferences, and larval performance of Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae) on Brassica napus L. were examined in a series of laboratory experiments. The associations between C. obstrictus...
