Acidification and Climate Warming: Understanding the Impact of Multiple Anthropogenic Stressors on Adirondack (NY, USA) Lakes
(2014-05-05)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 ... -
Assesing biological recovery from acidification and metal contamination in urban lakes from Sudbury, Canada : a paleolimological approach
(2008-07-11)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 ... -
Assessing Biological Recovery of Cladocera from Sudbury-Area Lakes Using Paleolimnology
(2014-04-28)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 ... -
Assessing Diatom Shifts in Embayments and Lakes in and Around Georgian Bay (Lake Huron) Using Paleolimnology
(2016-04-22)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 ... -
Assessing the Role of Declining Calcium in Biological Recovery on Zooplankton in Historically Acidified Lakes
(2015-05-28)Throughout much of the 20th century, industrial emissions caused the widespread acidification of thousands of lakes in North America and Europe. Acidification has led to unprecedented damage on zooplankton communities, ... -
Assessment of Long-Term Changes in Water Quality from Halifax Region Lakes (Nova Scotia, Canada) Using Paleolimnological Techniques
(2009-09-10)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 ... -
Chemical and biological recovery of Killarney Park, Ontario Lakes (1972-2005) from historical acidification
(2007-10-01)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 ... -
Diatom Community Responses to Water Quality Improvements in Lakes Recovering From Acidification and Metal-Contamination Near Wawa, Ontario, Canada: a Paleolimnological Perspective
(2009-04-30)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 ... -
The Role of Dispersal During the Recovery of Acid-Damaged Zooplankton Communities
(2011-12-21)Ecologists studying acid-damaged zooplankton communities have often documented a time lag in recovery following pH increases. While previous work has provided a solid understanding of the local factors that may delay ...
