The Alaska Highway through Southwestern Yukon is located in the discontinuous permafrost zone with many areas of the highway corridor associated with degrading permafrost. Given the strategic value of the corridor, it is critical to have a clear understanding of permafrost characteristics and...

Chemical and biological monitoring of muskeg drainage at the Alsands project site. Volume 1: Review of available data on the Muskeg River
Download1981
The available literature on the Muskeg River and its tributaries was critically reviewed as a background for monitoring' studies conducted on the river in 1980. The review indicated that the literature provides a basic description of the ecology of selected streams within the Muskeg River basin....

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...

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,...

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...
