Influence of Physical Factors and Exotics on Diporeia

This agreement provides funds to the US Geological Survey to undertake a focused assessment of current Lake Ontario benthic communities as associated with both physical and biotic factors in areas where Diporeia is no longer present and areas where they continue to be abundant. This contrast of communities will allow USGS to explore the changing ecological interactions between key benthic organisms and community interactions with physical factors. The data and analysis produced in this study will facilitate understanding the mechanisms of the change in what previously was a Diporeia dominated benthic community.  Comparison of observed community changes in Lake Ontario with other Great Lakes and cold deepwater lakes will help provide insight into the complex dynamics of the Great Lakes ecosystem. This kind of information is essential to the Lake Ontario Lakewide Management Plan (LaMP) and the ongoing native fish community restoration    effort in Lake Ontario, and will enhance development and implementation of LaMPs for the other Great Lakes.
