Research Interests

My research interests are in the areas of plant and ecosystem ecology. I know the most about grassland ecosystems and have spent my career working in either tallgrass prairie or dryer grasslands in the Great Plains. My master’s training took place in Kansas, at Konza Prairie, where I explored the role of bison grazing and fire in tallgrass prairie landscapes.

More recently, most of my research can be summed up as addressing the question: “What role do species play in ecosystems?”. The question is a key concern in an increasingly-human dominated world where, on one hand, some species are in danger of extinction and, on the other, some are becoming much more common and invasive. Thus, it is important to evaluate what effect species changes have on key ecosystem functions like productivity, soil fertility and water quality.

I am addressing this question of species effects by examining how plants contribute to productivity and soil nutrient dynamics within grassland and urban ecosystems. I’ve focused on non-native, invasive plants (smooth brome and reed canary) as well as some native prairie plants. My toolbag consists of descriptive work in the field, experimental work in both the field and greenhouse and more recently, remotely-sensed imagery of field sites. Most of my field sites are in or near Omaha in urban/suburban areas and nearby prairie and forested areas of the Missouri River valley. These sites and their particular problems have also motivated me to become well-versed in issues of conservation biology, prairie restoration and urban ecology.

I welcome motivated students to join me in joint research projects. Students may earn research credits and there are several sources of potential funding for summer work. Past research students have gone on to graduate study at University of Wisconsin, University of Hawaii, University of Maine, University of Nevada-Reno, Kansas State University, Colorado State University and University of Wyoming.
