Limnology

Recommended Prerequisites

General knowledge of Biology.

Teaching Methods

Theoretical, practical and laboratory, field and tutorial.

Learning Outcomes

This course focuses on the structure and functioning of freshwater ecosystems, with emphasis on phytoplankton, periphyton and macrophyte communities. In addition to a thorough knowledge about these ecosystems, it aims to instill / develop environmental concerns towards active, enlightened and responsible participation in preserving these systems and to encourage / develop the ability of  individual and / or group research.
