Underpinning the International Union for Conservation of Nature (IUCN) Red List is the assessment of extinction risk as determined by the size and degree of loss of populations. The IUCN system lists a species as Critically Endangered, Endangered, or Vulnerable if its population size declines...
Assessing opportunities and constraints in campus sustainability: The role of paper consumptionDownload
Clark, M. R., Isaev, N., Davidson, D. J.
This article presents the findings of a case study of paper consumption behavior at the School of Public Health at the University of Alberta. Using methods of social research such as survey, focus groups, and behavioral experimentation, we tested explanations of pro-environmental behavior with...
Assisted migration to address climate change: recommendations for aspen reforestation in western CanadaDownload
Mbogga, M. S., Chen, P., Gray, L. K., Gylander, T., Hamann, A.
Abstract: Human-aided movement of species populations in large-scale reforestation programs could be a potent and cost-effective climate change adaptation strategy. Such large-scale management interventions, however, tend to entail the risks of unintended consequences, and we propose that three...
Atmospheric Sb in the Arctic during the past 16,000 years: Responses to Climate change and human impactsDownload
Shotyk, W., Zheng, J., Krachler, M., Fisher, D.
Abstract: Applying strict clean room procedures and sector field inductively coupled plasma mass spectrometry (ICP-MS) methods, concentrations of Sb and Sc were determined in 57 sections of a 170.6-m-long ice core drilled on Devon Island, Arctic Canada, in 1999, providing a record of atmospheric...
Bioenergetic consequences of alopecia induced by Dermacentor albipictus (Acari: Ixodidae) on mooseDownload
Welch, D.A., Hudson, R.J., Samuel, W.M.
Fasting metabolic rates, respiration rates, respiratory minute volumes, and fasted weights were measured on three yearling moose (Alces alces (L.)) (Artiodactyla: Cervidae) infested with 50,000 winter ticks, Dermacentor albipictus (Packard) (Acari: Ixodidae), and on two uninfested controls....
Wein, R.W., Cumming, S.G., Flannigan, M.D., Krawchuk, M.A.
Lighting, fire is the dominant natural disturbance of the western mixedwood boreal forest of North America. We quantified the independent effects of weather and forest composition oil lightning fire initiation (a detected and recorded fire start) patterns in Alberta, Canada, to demonstrate how...
Boreal forest CO2 exchange and evapotranspiration predicted by nine ecosystem process models: Inter-model comparisons and relationships to field measurementsDownload
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...
Carabid Assemblages (Coleoptera: Carabidae) in a Rotation of Three Different Crops in Southern Alberta, Canada: A Comparison of Sustainable and Conventional FarmingDownload
Larney, F.J., Spence, J. R., Bourassa, S., Carcamo, H.A.
Carabids were sampled in 2000 (pretreatment year) and 2003-2005 in experimental plots in southern Alberta. Canada, after a rotation of beans, and potato under sustainable and conventional farming practices. Each phase of the rotation was present in every year. Crop type had stronger effect than...
Carbon and energy exchange by a black spruce – moss ecosystem under changing climate: testing the mathematical model ecosys with data from the BOREAS experimentDownload
Grant, R.F., Berry, J.A., Wofsy, S.C., Goulden, M.L.
There is some uncertainty whether net ecosystem productivity (NEP) of boreal black spruce forests is positive or negative under current climates and how NEP would change under hypothesized changes in future climates. The mathematical model ecosys was used to examine NEP of a boreal black spruce...
Changes in Oak Gall Wasps Species Diversity (Hymenoptera: Cynipidae) in Relation to the Presence of Oak Powdery Mildew (Erysiphe alphitoides)Download
Erbilgin, N., Ghosta, Y., Zargaran, M.R.
Plant-mediated interactions usually lead to multipartite interactions in a community of organisms. To evaluate the impact of oak powdery mildew Erysiphe alphitoides infestation on the distributions of cynipid oak gall wasps (Hymenoptera: Cynipidae), a field survey was conducted in West Azerbaijan...
