LAB OVERVIEW

Expertise: Our lab offers world-class expertise in food web interactions, fisheries management, limnology,
reservoir ecology, bioenergetics, population dynamics.  We employ an eclectic approach utilizing field studies,
laboratory experiments, and computer modeling, and state of  the art techniques such as hydroacoustics, stable isotope
analysis, and otolith microchemistry.

Partnerships: We collaborate with managers and researchers from federal, state and local agencies and
the private sector.

Mentoring: Undergraduate and graduate students are trained as scientists and gain valuable field and laboratory skills,
studying a wide variety of ecological problems, while working in close association with agency collaborators.

Education:  We offer courses in fish biology and fishery science for college credit as well as continuing
education workshops for professional development.


Recent Work:
  Predator-prey relationships among native and nonnative fishes, tracking the origins of
illicitly stocked fishes, the effects of nitrogen deposition in alpine lakes, impacts of dam operations on
reservoir food webs, and the effects of sport fishery harvest regulations and stocking.
