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 ...
Acidification and Climate Warming: Understanding the Impact of Multiple Anthropogenic Stressors on Adirondack (NY, USA) Lakes
Lakes in the Adirondack Park (NY, USA) are undergoing chemical recovery from acidification. There is now a pressing research need to define recovery targets for acid-impacted sites. Researchers attempting to designate such ...
Assessing Biological Recovery of Cladocera from Sudbury-Area Lakes Using Paleolimnology
Lakes near Sudbury, Ontario, experienced widespread acidification and metal-contamination beginning in the late-19th century. These stressors caused extreme damage to regional aquatic systems and their catchments, with ...
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 ...
