Description of Some Research Interests:
My research interests focus on environmental science, animal behavior, and ecology. In animal behavior I am particularly interested in the behavior of prairie dogs and fish of the family Cichlidae.
Questions being researched include:
In the area of water quality, investigations are being conducted to test nitrate levels in drinking well water in the Crete and Wilber area. This project is being conducted in cooperation with the Lower Big Blue River Natural Resources District. High nitrate levels are of concern because of problems associated with the absorption of oxygen by the blood in infants, birth defects, and may also be a cancer risk. In addition, investigations include changes in physical and chemical characteristics, such as dissolved oxygen and phosphate levels at Olive Creek Lake with the use of our sampling boat.
With regards to air quality, research is being conducted to test the levels of PM-10 (10 micron diameter) particulate matter in the air on the Doane campus. Particulate matter can increase the susceptibility to respiratory infections and can aggravate existing respiratory diseases, such as asthma and chronic bronchitis.
Regarding cichlid fish, work primarily revolves around the readily available convict cichlids. These are common aquarium fish and display many aggressive, territorial, and reproductive behaviors. Using timing software, investigations include the effects of temperature and caffeine on aggression and territoriality during the rearing of young. A future project involves the use of a night vision monocular, to test the hypothesis that light intensity affects aggressive behavior.

I participated in the Visiting Scientist Program at the University of Nebraska Center for Advanced Land Management Information Technologies (CALMIT). During this sabbatical I explored applications of electronic mapping technologies, such as global positioning systems (GPS) and geographic information systems (GIS), to environmental science, ecology and animal behavior.
