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...

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...

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...

Establishment and survival of ground cover plantings on disturbed areas in Alberta. Final report of Phase I.
Download1973
In February of 1973 a meeting of representatives from interested government agencies and industries was held in Edmonton in order to determine the need for research on the revegetation of disturbed areas in Alberta. As a result of this meeting a research project was set up to study the...

Hybrid poplar plantations have the potential to produce large amounts of biomass for the forest industry, but the young trees are sensitive to competition. This research attempted to quantify the influence of factors regulating competition in hybrid poplar plantations under four years old. The...

Impacts of clear-cut harvesting on carabid beetle (Coleoptera: Carabidae) assemblages of aspen dominated forests in central Alberta
DownloadFall 2016
Disturbances, both natural and those related to human activity, reset succession in boreal ecosystems, and affect forest biodiversity. The link between forest harvesting and biodiversity is of considerable conservation concern. In this thesis, I investigate the impacts of clear-cut harvesting on...

This report summarizes up to 39 years of plant community development trends on Syncrude’s reclaimed mine sites near Fort McMurray, Alberta. These trends are contrasted with a target condition, defined here as the Natural Range of Variability for species composition on older (60+ yrs) closed...

Salvage logging, edge effects and carabid beetles: connections to conservation and sustainable forest management
Download2006
Cobb, T.P., Brigham, R.M., Philips, I.D., Spence, J.R.
We used pitfall traps to study the effects of fire and salvage logging on distribution of carabid beetles over a forest disturbance gradient ranging from salvaged (naturally burned and subsequently harvested) to unsalvaged (naturally burned and left standing). Significantly more carabids were...
