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 ...
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 ...
Assessing Diatom Shifts in Embayments and Lakes in and Around Georgian Bay (Lake Huron) Using Paleolimnology
Freshwater ecosystems in Ontario are affected by a growing number of multiple stressors, with climate change often acting as a “threat multiplier”. Diatom-based paleolimnological approaches are used to provide the much ...
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 ...
