Research Interests:
The Turner laboratory is working on a broad range of questions in limnology and aquatic ecology. Our approach is mechanistic: we seek to understand system-level patterns by elucidating the underlying processes. We recently began work on a five year project, funded by the National Science Foundation, aimed at evaluating the role of trait-mediated indirect interactions in mediating community and ecosystem level processes in lakes and marshes. We are also working on a number of conservation and restoration oriented projects. As a post-doc I worked on the restoration of the Florida Everglades, and here in Pennsylvania I am involved in the assessment and remediation of acid-mine drainage. We are also working to better understand the effects of acid deposition on food web structure and function in cold-water streams. Our newest and perhaps most exciting project is the investigation of how pollution my impair the sensory systems of freshwater organisms. For example, we have found that eutrophication results in elevated pH, which in turn impairs the olfactory systems of aquatic animals and limits their ability to find food and avoid predators. A knowledge of how information transfer between organisms may be disrupted by pollution is crucial to better understanding the overall effects of water pollution on aquatic ecosystems.
