The course introduces participants to the diversity, identification, and ecological significance of aquatic macroinvertebrates in Switzerland. Participants learn about the most important groups, identify common species based on characteristic features, and identify other representatives using standard identification keys. An excursion provides practical experience with common sampling methods.

This course aims at developing research skills in environmental biology. Students carry out small research projects in terrestrial and aquatic ecology, ecological genetics, and population biology. Students analyse their data statistically and present the results both orally and in written reports.
