Research Interests
My research is
directed at applying ecological principles to the conservation and management
of aquatic ecosystems. I am interested in trophic interactions, reservoir
ecology, effects of nonnative fishes, fisheries management, limnology,
bioenergetics, population dynamics, quantitative models. My current work is
focusing on anthropogenic influences on aquatic ecosystems such as climate,
invasive species, reservoir operations, sport fishery harvest regulation, fish
stocking, and contaminants. I enjoy applying a wide variety of techniques and
approaches including field sampling, modeling, field experiments, classical
fisheries biology analytical techniques, stable isotope analysis, and otolith
microchemistry. I am building bridges (excuse the pun) between aquatic
ecology and environmental management with water researchers in CSU's engineering
departments. Most of my projects benefit from close collaboration with
managers and researchers from Colorado Division of Wildlife, U.S. Bureau of
Reclamation, U.S. Fish and Wildlife Service, and folks in several other state
and federal agencies.
Teaching
My teaching
responsibilities include our senior-level Fishery Science course FW401 which stresses
the quantitative aspects of fishery biology and fishery management. This course
includes a laboratory section for hands-on experience with concepts discussed
in lecture; labs stress computer applications for fishery analysis. I also
teach Ichthyology FW300
and FW301 which
cover fish anatomy and physiology, evolution and systematics, ecology,
genetics, zoogeography, and conservation biology. I regularly co-teach graduate
seminars and give numerous guest lectures in undergraduate and graduate
courses. I draw heavily on my research experience to provide
contemporary, interesting and illustrative examples for all of my courses.
Here are a couple of web resources I developed for my classes: Fish ID flashcards | Field Guide to Colorado-Wyoming Fishes
