Detecting changes in zooplankton following the recovery of river herring in the Penobscot

River herring populations have declined dramatically and remained low for over a century after dams were built that blocked access to their spawning habitat. The primary goal of this project is to determine how and if diet selectivity has changed, explore how alewife alter zooplankton communities through selective feeding, and predict community changes as recovery progresses and extend these results to other dam removal projects.
