300295 UE Field course "Biodiversity of freshwater ecosystems" (2021S)

In this field course our study objects range from oligotrophic and dystrophic pre-alpine lakes over ponds and pit mosses to running waters and groundwater bodies (Base: watercluster Lunz). In case that overnight stays should be forbidden due to enforced corona measures, we will perform day excursions from Vienna , ranging from impoundments and Danubean backwaters over ponds and pit mosses to running waters in the Wienerwald area. Introductory lectures provided as pdfs on moodle and short introductions in the field give insight into geology, landscape ecology, abiotic and biotic interactions, measuring and sampling techniques as well as identification of algae, macrophytes, aquatic invertebrates and fish, using identification tables specifically composed for this course. In the lab, samples are analysed and identified and field data (e.g. underwater light data, limnochemical and hydraulic data) processed and discussed.
