Using Paleolimnology to Reconstruct Past Environments of Lakes Affected by Direct Anthropogenic Activities
(2015-07-29)
Although the magnitude of recent anthropogenic environmental change is unprecedented, humans have been leaving measurable footprints on the landscape prior to the era of industrialization. This thesis examines the long-term ...
Assessing Thule Inuit impacts on High Arctic lakes and ponds : a paleolimnological approach
(2008-01-03)
Until recently it has been widely believed that significant anthropogenic influences on the environment began in Canada following the onset of European colonization. However, our paleolimnological data indicate that ...
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 ...
A diatom-based paleolimnological study of water-quality changes related to multiple anthropogenic stressors in Lake Simcoe
(2010-08-04)
Freshwater systems in Canada are affected by a multitude of environmental stressors, including cultural eutrophication, introduction of non‐native species, and
climate change. Multiple stressors can interact in unpredictable ...
The Response of Discostella Species to Climate Change at the Experimental Lakes Area, Canada
(2014-07-02)
Global climate change is threatening both our water quality and quantity. Specifically, the influence of climate change on freshwater lakes includes decreased water availability, increased evapotranspiration, changes in ...
Biomanipulation in two Ontario Precambrian Shield lakes: a multi-proxy paleolimnological analysis
(2012-10-18)
Food web biomanipulations provide the means to partly control water quality problems (i.e. algal blooms) in lakes by altering internal ecological mechanisms. However biomanipulation mechanisms are complex and the results ...
A PALEOLIMNOLOGICAL EXAMINATION OF CLADOCERAN (BRANCHIOPODA, CRUSTACEA) ASSEMBLAGES IN SOFTWATER NOVA SCOTIA (CANADA) LAKES AND THEIR RESPONSES TO MULTIPLE STRESSORS
(2012-08-22)
The Canadian province of Nova Scotia has an abundance of lakes impacted by multiple stressors, including acidification, lakewater calcium (Ca) decline, climate change, and fish introductions. In spite of this, little is ...
A comparative paleolimnological assessment of the influences of early Arctic population groups on freshwater ecosystems from southern Baffin Island, Nunavut
(2011-10-04)
Recent paleolimnological research in the eastern Canadian high Arctic on the ecological impact of the Thule c.1000-1500 AD has documented the influence of prehistoric anthropogenic activities. Six lake and pond sites ...
Paleoecological Reconstruction of the Holocene Fire Regime at Mud Lake, Eastern Ontario, near St. Lawrence Islands National Park
(2010-02-01)
Wildfire is an ecological disturbance that plays an important role in ecosystem function and interacts with climate and vegetation, relationships that may be altered by ongoing climate change. Insights from paleoecology ...
Importance of Climate on Boreal Lakes from Northwest Ontario Over Millennia: A Paleolimnological Perspective
(2014-12-08)
The lack of long-term data on the response of boreal lakes to climate change has been seen as an impediment to the assessment of the vulnerability and risks that northwest Ontario faces in light of future climate change. ...
