As a term, sustainability has often come to be adopted as the 'panacea' for many problems without any clear understanding that the solutions will vary given the nature of the problem, the scale involved and the goals and objectives set out. As a result, what has emerged in the literature has been many different 'pictures' of sustainability, all of which may be relevant in certain contexts. This research examined the potential of the concept within the context of Canadian national parks. Emphasis was directed toward understanding, through the perceptions of 'expert' groups knowledgeable about parks, the key elements needed to promote parks as sustainable landscapes. The methodology used consisted of the implementation...

This study focussed on the development and evaluation of bioassessment methods for wadeable streams of the Yukon River basin within Yukon Territory. There were three components to this study. The first was the detailed development, evaluation and comparison of Reference Condition Approach (RCA) bioassessments using fish and benthic macroinvertebrates (BMI) from the same stream sites. Second, methods were developed for examining the relationships between stream biota and a gradient of placer gold mining. Finally, the statistical power of bioassessments developed for the Yukon River basin was evaluated by applying the bioassessments to stream site data subjected to simulated impacts. Comparison of RCA bioassessments...

Anthropogenic greenhouse gas emissions may be offset by sequestering carbon dioxide (CO2 ) through the carbonation of silicate minerals. In the natural environment, microbes can aid in silicate dissolution and carbonate precipitation, and therefore, can potentially be used to catalyze carbonation reactions. The hydromagnesite playas of Atlin, British Columbia, Canada provide a natural model to examine mineral carbonation on a watershed scale. At near surface conditions, microorganisms are involved in weathering of bedrock and precipitation of carbonate minerals, which results in CO 2 sequestration. Regions with ultramafic bedrock, such as Atlin, represent the best potential sources of feedstocks for mineral carbonation....
