David BiesboerDavid D. Biesboer, Professor and Director

612-625-1799 |

Dr. Biesboer's lab focuses on the study of nitrogen cycling in wetlands; ecoystem studies; ecophysiology and anatomy of higher plants; and vegetation management. Current projects include studying the use of grasses to control erosion in Minnesota; nitrogen cycling in coastal lagoons and dry forests of Brazil; nitrogen cycling in a bog in northern Minnesota; and the population dynamics of wild rice in/near Lake Itasca.

Muir EatonMuir Eaton, Associate Professor at Drake University

515-271-2821 |

Research interests focus on the evolution of characteristics among birds, ranging from plumage coloration to ecological niches, using a comparative phylogenetic approach. (EEB 4844, Ornithology)

Leif HembreLeif Hembre, Professor at Hamline University

651-523-2254 |

Research interests include the evolutionary biology of organisms that alternate between asexual and sexual reproduction, aquatic ecology, acoustic analyses of zooplankton, and invertebrate biology. (EEB 3807, Ecology)


Sarah Knutie, PhD

Dr. Knutie is interested in the evolutionary ecology of host defenses against parasites. She is particularly interested in how environmental change affects host-parasite interactions in bird and amphibian systems.  Her research takes her to local (Itasca Biological Station) and international (Galapagos Islands) field sites to answer both conceptual and applied questions in disease ecology.

Joe WhittakerJoe Whittaker, Assistant Professor at Concordia College, Moorhead

Research interests include the natural history and ecology of small mammals. Much of Joe’s research has focused on the population dynamics and habitat use of shrews and voles. He is an alum of the Itasca Biological Station, and his Master’s field research was conducted near the Itasca Biological Station. He earned his M.S. at the University of Minnesota - Duluth and completed his Ph.D. in Zoology from Southern Illinois University at Carbondale. (EEB 4839, Field Mammalogy)

Brian WisendenBrian D. Wisenden, Professor at Minnesota State University - Moorhead

Interested in behavioral ecology of fishes including patterns of parental care, mating systems, chemically-mediated predator-prey interactions and host-parasite interactions. (EEB 3811, Animal Behavior)
