Students will obtain basic knowledge on how ecological properties and processes of aquatic environments, particularly of lakes, relate to the terrestrial ecosystem and the atmosphere, thus obtaining an integrative approach. A central topic in this lecture is the connectivity among chromophoric dissolved organic matter, underwater optical properties, effects of solar ultraviolet radiation, and mechanisms of photoprotection.

Introduction and basic concepts. Relative importance of the atmospheric and underwater 'ozone hole',  optical properties of the aquatic medium.  Sources and characterization of dissolved organic matter (DOM) and interactions between solar radiation and chromophoric DOM. Mechanisms and strategies of UV protection in aquatic organisms.  Effects of solar radiation at different organizational levels (molecular to ecosystemic).

Lecture, assessment is based on a single examination at the end of the course.
