Six woody forest species showed a gradual decline in CO2 gas exchange which was related to symptom development characteristic of SO2 toxicity. Paper birch most sensitive species, black spruce least

Jack pine, when fumigated with SO2 at the ambient air quality standards, exhibited various biochemical responses that can have a deleterious effect on the normal growth and yield of vegetation.

General objective of this study was to describe the baseline states of the fish component of the MacKay River watershed, the largest basin on the west side of the Athabasca River

The resident fish fauna of the Steepbank River consists largely of pearl dace, brook stickleback, lake chub, longnose dace and slimy sculpin.

The impact of saline waters upon freshwater biota, having special reference to the AOSERP study area, is reviewed. Toxicity summaries for individual ions are presented.

Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace River

The analysis of bear-human interactions in the AOSERP study area indicated that the major conflict arises from nuisance bears attracted to areas by garbage

Winters are cold with relatively little snow. About two-thirds of the precipitation falls in the summer months with several major rainstorms generally accounting for much of the seasonal rain

Colonization of limestone gravel, limestone gravel + organic matter, and limestone gravel from a river bed was followed over time to compare two possible stream reclamation substrates with a control

Artificial substrates were employed, water chemistry parameters measured, taxonomic identifications carried out, and productivity measurements conducted to elucidate bacterial and algal productivity
