Mussels are one of the most threatened groups of animals in North America, with over 71% being listed as endangered, threatened or of special concern. Studies of mussel populations have shown a relationship between loss of mussel species richness and agricultural land use. Since North Dakota is largely an agricultural state, the need exists to document the current status of North Dakota mussel populations. A two-year study has been funded by the North Dakota Game and Fish Department. The first-year will be an assessment to determine the mussel species distributions in North Dakota. Thus the two main purposes of the first-year survey is to provide species lists within a sampling site and determine species distribution throughout the state. We anticipate sampling approximately 100 sites this first summer. The entire project team will consist of four students, two biology faculty (Concordia and Valley City State University) and one technician. Students applying as research assistants should feel comfortable working in water and be able to swim. The project requires travel throughout North Dakota, staying overnight in motels and/or camping. Travel expenses will be paid by the project grant. The summer portion of the project will run at least 10 weeks. Research assistants may also have the opportunity to work on this project during the academic year. During this time selected shells will be thin-sectioned for age determination. Age information will provide some valuable demographic data on mussel populations.
