Assessment of Long-Term Changes in Water Quality from Halifax Region Lakes (Nova Scotia, Canada) Using Paleolimnological Techniques
The current study developed a paleolimnological approach to assess changes in diatom assemblages (class Bacillariophyceae) from present-day lake sediments in comparison to those deposited before significant human impact ...
Assesing biological recovery from acidification and metal contamination in urban lakes from Sudbury, Canada : a paleolimological approach
The acidification and metal contamination of freshwater resources are major environmental concerns in many areas, with Sudbury (Ontario, Canada) having been amongst the most severely impacted. Many scientific investigations ...
Diatom Community Responses to Water Quality Improvements in Lakes Recovering From Acidification and Metal-Contamination Near Wawa, Ontario, Canada: a Paleolimnological Perspective
In response to sulphur dioxide emission reductions in North America and Europe, there has been a recent shift in research focus towards understanding ecosystem recovery. Evidence for reversibility in the effects of ...
Chemical and biological recovery of Killarney Park, Ontario Lakes (1972-2005) from historical acidification
Forty-five lakes in Killarney Provincial Park and the surrounding area in south-central Ontario, Canada, were sampled for crustacean zooplankton and water chemistry in the summer of 2005. For each of the lakes, we had ...
