Aquatic Invertebrates: Laboratory Analysis

This lecture covers the laboratory analysis of aquatic macroinvertebrates, focusing on the IBCH 2019 modular system. The instructor demonstrates the process of sorting and identifying various invertebrates, such as Ephemeroptera, Plecoptera, Trichoptera, and Diptera larvae, using a magnifying glass. The lecture emphasizes the importance of accurate identification and classification of these organisms for ecological assessments, culminating in the calculation of a quality score based on taxonomic variability. The instructor also highlights the significance of using specific coefficients for different hydrological regimes to determine the ecological status of water bodies.
