Courses
Research
I am especially interested in fish populations of the Great Lakes and the cool
water fish communities of Minnesota's larger lakes. Impacts of exploitation
on fish communities and the effects of exotic species on endemic fauna are also
special interests. I anticipate that the "biochronology" of fishes, i.e. reading the environmental history of fish from growth increments
in bones and otoliths, will provide insights into the effects of management
and the ecology of freshwater fishes. My biochronology
research group is currently exploring the use of this technology in interpreting
the holarctic ecology of several species of freshwater fish. We are currently
developing a new age determination method for fish using growth increments to
define "temporal
signatures" useful in studies of fish ecology and archaeometry.
Most of my students do research that is quantitative or statistical in nature,
sometimes including computer programming and simulation modeling. I am also
interested in natural resources policy issues including Native American fish
and wildlife management, conflict resolution, and the efficacy of freshwater
fishery management. Further details of research in progress may be found on
the Internet at my professional
interests Web site.
