Description of four new species of gill flukes (Dactylogyrus) from minnows of the Great Plains.
Abundance of flukes (Digenea) in crayfish related to water quality of lakes and stream in northern Minnesota.
Prevalence of Heterosporis (Microsporidia) related to sex, age, and condition of yellow perch in Leech Lake.

Dr. Mark Fulton is a vegetation ecologist with a particular interest in the structure and dynamics of forest communities. Particular areas of activity, many in collaboration with Paul Harcombe of Rice University, have included: simulation modeling of forest dynamics, statistical modeling of demographic processes in forests from long-term data using information statistics, and applications of an operational definition of multivariate "predictability" of community change. Developing interests include: linkages between canopy tree and understory dynamics, light environments in tree canopies, and constraints on maximum tree height. Recent publications include:

Dr. Debbie Guelda is an aquatic ecologist and specifically a river researcher at heart. Her graduate research concentrated on invertebrates in the lower Ohio watershed, particularly zooplankton. She is interested in how populations of plankton change in a river continuum both temporally and spatially. She brought this research to northern Minnesota where she is interested in how zooplankton communities change while traveling through Mississippi river-lake sequences. She is also interested in how planktonic (open water) invertebrates are energetically linked to benthic (bottom-dwelling) invertebrates in these systems. Her research has been presented both nationally and internationally at meetings of the North American Benthological Society (Vancouver, BC, Anchorage, Alaska - June 2006) and the American Society of Limnology and Oceanography (Copenhagen, Denmark and Santiago de Compostela, Spain). Recent publications include:

Dr. Patrick Guilfoile: My students and I use the tools of Molecular Genetics to study a variety of systems, particularly those involving parasites and hosts. Some of my more recent work has been the study of Ixodes scapularis ticks that transmit Lyme disease. This work has included a range of techniques from field collection to cDNA library construction and screening. In the past year, I have put more focus on working with aquatic animal parasites, working in collaboration with Dr. Donald Cloutman. This work has included molecular analysis of a common crayfish parasite, and the study of several fish parasites. One of the big questions we are examining is the genetic diversity of parasites based on their life history. In addition, I am interested in the development of laboratory exercises in microbiology and molecular genetics, and I am currently developing a microbiology laboratory manual with a somewhat molecular focus.

Dr. Michael Hamann: My research interests include cellular motility and how low molecular weight GTPases participate in events that control cell movement and shape. Besides controlling migration, GTPases frequently act as signaling nodes within cells, and they participate in a wide variety of cellular events through their interactions with a series of upstream and downstream effector proteins. Understanding their function could provide the basis for developing anti-metastatics, compounds that could inhibit cell migration and metastasis in cancer. Recent publications include:

Dr. Elizabeth Rave is a vertebrate biologist who specializes on nongame birds and mammals. Her graduate research concentrated on the population genetics of Nene (Hawaiian Geese) and the population biology of Alabama beach mice. She continues her research on endemic birds in Hawaii, where she collaborates with personnel from the National Park Service and the Hawaii Department of Land and Natural Resources. She is currently studying the use of artificial nesting structures by Koloa (Hawaiian Ducks) on Maui. She has presented her findings at international meetings of the Society for Conservation Biology and the American Ornithologists' Union. Recent Publications include:
