Ecology and Systematics of Diatoms

May 17 to Jun 11

8:00am - 5:00pm 

This course is an intensive, field-oriented class appropriate for advanced undergraduate students, graduate students, and post graduate workers in ecology, geology, environmental sciences, and diatom taxonomy. We will immerse ourselves in the diverse aquatic habitats and fossil deposits of the Upper Midwest to observe freshwater diatoms. Students will learn techniques in diatom collection, preparation, and identification. Lectures will cover taxonomy, systematics and biogeography of most freshwater genera. Students will complete individual voucher collections using modern database techniques and produce a written species treatment using guidelines for electronic publication. Students are encouraged to bring research materials. The use of diatoms in ecological and paleoecological research will be discussed.

Instructors: Mark Edlund, St. Croix Watershed Research Station, Science Museum of Minnesota. Sylvia Lee, United States Environmental Protection Agency.

The John C. Kingston Diatom Fellowship was established in 2004 by colleagues, friends and family to honor John's memory and to recognize the contributions he made to the study of diatoms at Iowa Lakeside Laboratory. Each summer, an award is made to one advanced student or researcher to serve as teaching assistant for the Ecology and Systematics of Diatoms course and to engage in a research project. The fellowship includes a stipend and room and board at Lakeside and is available to domestic and international students, at the graduate level or advanced undergraduate level. See the Iowa Lakeside Lab webpage ( to apply.  The JC Kingston Fellowship is administered by the Friends of Lakeside Lab.
