An Inquiry-Based Investigation of Freshwater Diatom Ecology

Understanding habitat heterogeneity and habitat preference are central tenets of undergraduate ecology courses, but many urban campuses, particularly community colleges and others with large student enrollments, may lack the means for extensive field sampling and monitoring. We outline the use of diatoms living in decorative water fountains as a proxy for field sample collection, data analysis, and ecological interpretation. These methods are amenable to undergraduate laboratory courses and independent student research projects.
