Chemical and biological monitoring of muskeg drainage at the Alsands project site. Volume II: Monitoring and fish studies
Download1981
Reid, D. E., Walder, G. L., Stushnoff, R., Mayhood, D. W., Green, R. B., Dickson, T.
Volume I of this report reviewed the publicly available literature on stream environments in the Muskeg River basin as background to the monitoring studies. This volume (Volume II) describes the results of the studies, discusses their effectiveness, and makes suggestions about the design of...

1990
Many autecological effects of temperature on fish are known, and fishery biologists have begun to incorporate this knowledge into population-level relations that can be used to assess possible effects of climatic warming on fishes and their habitats. However, the problem of extrapolating these or...

Mosasaurs (family Mosasauridae) are a diverse group of secondarily aquatic lizards that radiated into marine environments during the Late Cretaceous (98–65 million years ago). For the most part, they have been considered to be simple anguilliform swimmers – i.e., their propulsive force was...

Density-Dependent Effects and the Regulation of Crucian Carp Populations in Single-Species Ponds
Download1994
Tonn, W. M., Holopainen, I. J., Paszkowski, C. A.
Crucian carp (Carassius carassius) is often the only fish species present in small ponds of northern Europe. Such populations are typically at high densities and consist primarily of small, relatively slender, and short-lived fish; populations in multispecies assemblages in lakes display opposite...

Development of a Toxin-Mediated Predator-Prey Model Applicable to Aquatic Environments in the Athabasca Oil Sands Region
Download2014-12-01
Huang, Q., Wang, H., Lewis, M.A.
Industrial contaminants are one of the leading causes of pollution worldwide. It has been shown that 13 elements considered priority water pollutants by the US Environmental Protection Agency are present in the Athabasca River and are found in oil sands process-affected water. There are likely...

Early life exposure to stress can have life-long effects on an organism. These effects may be detrimental, or they may be adaptive if they allow the organism to develop an adult phenotype which better matches the environment predicted by the stressor. Early life stress influences many traits,...

Spring 2012
Decades of fish introductions into mountain lakes have altered invertebrate communities. I assessed the current status of fish populations and their effects on crustacean zooplankton communities by sampling 37 lakes in the mountain parks, where stocking practices had been halted over 25 years...

Enhancing productive capacity in the Canadian Arctic: Assessing the effectiveness of instream habitat structures in habitat compensation
Download2004
We examined the effectiveness of physical habitat structures (ramps, V-weirs, vanes, and groins) at increasing the productive capacity of a newly created 3.4-km artificial stream in the Barrenlands region of the Northwest Territories, Canada. We quantified changes in fish density and growth in...

Fall fisheries investigation in the Athabasca and Clearwater rivers upstream of Fort McMurray Vol I
Download1978
McCart, P. J., Mann, G. J., Jones, M. L.
Fisheries investigations were undertaken in the Athabasca and Clearwater rivers upstream of Fort McMurray in the fall of 1977. The major emphasis of these studies was to delineate actual and potential spawning areas for lake whitefish in the Athabasca and Clearwater rivers. Lake whitefish were...
