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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
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, ...
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 ...
Windows of opportunity: the timing of dispersal events influences zooplankton community response to environmental change in Subarctic ponds
(2012-09-17)
Theoretical and empirical work has shown that community diversity and composition can be influenced by both local conditions and dispersal from a regional species pool. This may be especially true shortly after environmental ...
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 ...
