Practical Course Macroinvertebrates

Abstract

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.

Objective

Upon completion of the course, students will be able to: 1. Correctly name the most common aquatic macroinvertebrates in Switzerland at the order or family level. 2. Recognize and describe characteristic morphological features for the identification of typical taxa. 3. Confidently apply common identification keys for Switzerland. 4. Implement methods for sampling and preservation in the field and reflect on their areas of application. 5. Explain the relevance of aquatic macroinvertebrates for ecological research and bioindication.
