Addressing anthropogenic and environmental perturbations in aquatic systems
The overall goal of the set of experiments described in this dissertation was to better understand the influence of a variety of perturbations in aquatic ecosystems using multiple analytical and methodological approaches. I used these techniques to address three important challenges currently facing aquatic systems managers, including: 1) alewife die-offs in the Great Lakes and other freshwater systems 2) elevated thiaminase activity in clupeid fish and 3) mercury contamination in aquatic food webs. My objectives were to better understand and in some cases explore potential means to remediate negative impacts associated with these issues by using a variety of metrics as indicators of anthropogenic and environmental perturbation.
