Application of manure from cattle fed with different diets affects soil properties and greenhouse gas emissions
DownloadSpring 2019
Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

Approaches to the design of a biomonitoring program using arthropods as bioindicators for the AOSERP study area
Download1980
Present oil sand extracting plants are licensed to emit up to 635 t of S02 per day, along with large quantities of other gasses and fly ash. Additional oil sand extraction plants are in the planning stages. The cumulative effect of additional plants will tax the ability of the local environment...

Biodiversity of soil arthropods in a native grassland in Alberta, Canada: obscure associations and effects of simulated climate change
DownloadFall 2013
Soils have traditionally been treated as a “black box” due to the challenges of studying this complex medium. The living component of soil consists of a complex network of roots and mostly very small, highly abundant, and extremely diverse group of microbes, protists, and other invertebrates. In...

Boreal forest CO2 exchange and evapotranspiration predicted by nine ecosystem process models: Inter-model comparisons and relationships to field measurements
Download2001
Wofsy, S.C., Frolking, S.E., Wang, S., Clein, J.S., McGuire, A.D., Potter, C.S., Goulden, M.L., Chen, J.M., Grant, R.F., Nikolov, N.T., Amthor, J.S., Kimball, J.S., King, A.W.
Nine ecosystem process models were used to predict CO2 and water vapor exchanges by a 150-year-old black spruce forest in central Canada during 1994-1996 to evaluate and improve the models. Three models had hourly time steps, five had daily time steps, and one had monthly time steps. Model input...

Conservation of forest-dwelling arthropod species: simultaneous management of many small and heterogeneous risks
Download2008
Volney, W.J.A., Langor, D. W., Jacobs, J. M., Work, T. T., Spence, J. R.
The Canadian insect fauna is too inadequately Understood to support well-informed assessments about its conservation status: however, the foregoing collection of synthetic papers illustrates potential threats front industrial forestry. Loss of forest species and dramatic changes in forest insect...

Cannon, K.R., Finlayson, N.M., Landsburg, S.
A study was initiated in 1988 to evaluate the effects of pipeline construction on soil compaction in the province of Alberta. The pipelines were located throughout Alberta on a number of different soils and were constructed using various techniques. Cone penetration resistance of soils (soil...

Effect of Pipeline Construction on Soil Strengths of Soil Horizons in Alberta: 1990 Final report
Download1991
Finlayson, N.M., Landsburg, S., Cannon, K.R.
This study was initiated in 1988 to evaluate the effects of pipeline construction on soil strengths of various soils in the province of Alberta. The pipelines were scattered throughout Alberta on a number of different soils and were constructed using various techniques. At each of the fifteen...

Effects of crop rotation and genetically modified herbicide-tolerant corn on ground beetle diversity, community structure and activity density
Download2010
Spence, J.R., Floate, K., Blackshaw, R.E., Bourassa, S., Carcamo, H.A.
Ground beetles (Coleoptera. Carabidae) were sampled in conventional and genetically modified herbicide-tolerant (GM HT) corn, Zea mays L. (Poaceae), planted under rotation with canola, Brassica L. (Brassicaceae), or continuously cropped corn to investigate the influence of corn variety and...
