Professor of Limnology
My research interests encompass the fields of stream and wetland ecology. By the
nature of its scope, aquatic ecology spans a broad array of subdisciplines such
as geomorphology, hydrology, nutrient cycling, bioenergetics, energy flow through
food webs, and population and community ecology. The continuing goal of my research
is a synthesis of these many areas of organismal biology and ecology and their
application toward holistic understanding of stream and wetland environments.
This goal has led me to investigate a broad range of topics, for example the interaction
of temperature and stream hydrologic cycles on growth and production of stream
invertebrates; nutrient and organic matter dynamics in disturbed stream systems;
the role of large wood debris in bull trout spawning habitat; and the role of
hydrology and geomorphology on wetland vegetation structure and function.
Teaching has always been an important part of my professional life. I have taught
across a range of students and courses from General Biology for non-majors to
upper level undergraduate and graduate level courses in Stream Ecology and Limnology.
I find teaching to be exciting and a new challenge each year with a different
cohort of students with varied personalities and backgrounds. Currently, I teach
stream ecology each summer at Flathead Lake Biological Station, and have done
so since summer 1983. Teaching stream ecology within the Flathead Lake Biological
Station teaching environment stimulated the conception and development of the
book Methods in Stream Ecology, which I co-edited with my colleague, Dr. Gary
