Fields of Interest
Fish population and community dynamics, watershed management and restoration
Research
My research efforts are divided between Minnesota's large walleye lakes
and other water bodies, including smaller lakes as well as large rivers.
On the large walleye lakes, I am studying recruitment mechanisms of percid fishes,
primarily walleye and yellow perch. I am assisting with the development of
management
regimes to control harvest. My large lake research also entails a variety
of modeling methodologies, including simulation and operational models to evaluate
management strategies. I maintain an interest in climate effects on fish
dynamics,
and I plan to continue my earlier work on freshwater drum dynamics by estimating
growth and recruitment chronologies for this species (i.e., biochronology) from a variety
of sites and at several spatial scales.
I am also developing new interests in watershed management and restoration.
One of my current research projects involves development of an index of biotic
integrity for lakes, and will use the stateÍs extensive fish community
database. Future research may involve development of spatially explicit models
to assist watershed management programs; these models may be used heuristically
to compare metropolitan area as needed to protect water quality.
