Information

Aims, contents and method of the course

The lecture emphasis the role of primary producers in freshwaters by ecophysiology, photosynthesis, ecological stoichiometry and community interactions and starts with an introduction on the variety of photosynthetic organisms in freshwater systems. The key issues lectured in the beginning are acclimation to light and nutrient availability, the assessment of resource limitation, algal growth as beneficial or nuisance component in ecosystems (link to other microbial organisms, food chain interaction, effects of toxins by cyanobacteria), and photo-autotrophic community structure. In the second part the wider implication of the response of primary producers to pollution and global climate change will be communicated. Both practical issues are addressed by recent research initiatives of the European community, the 'European Water Framework Directive' and the 5-6thframework programmes. The last 6h of the lectures are understood as a practical computer guide and aimed to give simple examples for tools of nutrient bio-assessment and of the analysis of the response to climate change. The lecture hand-out includes electronically prepared long-term data-sets, display methods and analytical tools for the applied freshwater issues.

Assessment and permitted materials

Die Prüfung erfolgt mündlich via online Abfrage, für StudentInnen einzeln oder in kleinen Gruppen via Skype (https://join.skype.com/mF0qBrToi8VV (VL Algen der Binnengewässer - TEUBNER), Link siehe auch e-mail Aussendung). Die StudentInnen werden zu Themen der Einleitung sowie einem Teilthema der Ökophysiologie (Teil a Pigmente oder b Nährstoffe + Trophie-Modelle der
Seen) sowie einem Teilthema der angewandten Ökophysiologie (Teil a Klima oder Teil b EU Wasserrahmenrichtlinie) befragt. Die StudentInnen können dabei selbst die drei Teilthemen wählen. Das Handout ist im Moodle verfügbar. Dort sind die Folien mit dem Schwerpunkt-Prüfungswissen mit einem blauen Punkt markiert. Weiters sind die Sprachaufzeichnungen der aktuellee Vorlesungsdurchführung für alle VL-Termine im Skype zum freien Download verfügbar (https://join.skype.com/mF0qBrToi8VV (VL Algen der Binnengewässer
- TEUBNER)). Diese Sprachaufzeichnungen sollen die Handouts im Moodle ergänzen.
