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 ...
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 ...
Cladoceran Responses to Environmental Change in High Elevation Andean Lakes
Andean lakes are hotspots of biodiversity and serve as critical freshwater resources for millions of people. However, little information is available regarding their ecological responses to anthropogenic climate change, ...
Assessing the chemical and biological recovery of Killarney Provincial Park lakes from historical acidification
Since the mid 1900s, acidification has impacted water quality and threatened the ecological integrity of thousands of lakes and streams across Eastern North America and Europe. After the implementation of industrial emission ...
Factors mediating the distribution and impact of the non-native invertebrate predator Bythotrephes longimanus
(2013-06-17)
Predicting the impacts of non-native species remains one of the greatest challenges to invasion ecologists. Because of their insularity, freshwater systems are particularly vulnerable to invasions, especially from non-native ...
The Relative Importance of Population Size, Colonist Quality, and Colonist Arrival Frequency for Population Success
Successful population establishment, subsequent population dynamics, and extinction have all repeatedly been shown to be affected by the quantity of initial colonists. However, there are other, less studied factors that ...
The Effects of the Non-Native Invertebrate Predator Bythotrephes Longimanus and Declining Aqueous Calcium on Crustacean Zooplankton Communities in Canadian Shield lakes
(2016-10-14)
Over the last several decades, human activities have resulted in environmental changes that have increased the number of stressors that can act on a single environment. In Canadian Shield lakes, two recent stressors, the ...
Daphnia vertical position and implications for the impact of the invasive zooplankton predator, Bythotrephes longimanus, on plankton communities in south-central Ontario
Species diversity and identity play an important role in determining community structure and regulating ecosystem processes. However, species interactions are often characterized by the mean effect or response, often ...
Effects of an invasive consumer on zooplankton communities are unaltered by nutrient inputs
(2014-01-31)
Interactions between multiple anthropogenic stressors can have unexpected synergistic or antagonistic effects, making it difficult to predict their combined effect using single stressor studies. The interaction between ...
Species response to rapid environmental change in a Subarctic pond
(2013-10-02)
Unprecedented rates of anthropogenic environmental change have resulted in dramatic decreases in biodiversity worldwide. In order to persist during changes in both the abiotic and biotic environment resulting from anthropogenic ...
