EDUCATIONAL OBJECTIVES The aim of the course is to provide students with the information necessary to understand the practical bases of the investigations of classical and modern ecology and the theoretical and experimental approaches that have allowed their development today. The bases will be provided for carrying out environmental monitoring activities in the field and on how to set up experimental plants in the laboratory. Expanding knowledge on aquatic organisms from a trophic-functional point of view. Students will have to learn the logic of ecosystem analysis of aquatic environments and the methodologies suitable for evaluating structures and functions of ecosystems in aquatic environments. Notions will be provided to understand the most recent developments in the ecosystem of aquatic environments (food web theory, niche theory, network analysis), and an understanding of the importance of managing these environments will be stimulated. The course aims to provide the basis for further in-depth studies in the fields of inland water ecology and community ecology.
EXPECTED LEARNING RESULTS Knowledge and understanding. Having developed knowledge of the principles and ecological laws that underlie the ecosystem functioning of aquatic environments. Having acquired the notions useful for undertaking ecosystem analyzes of the various environmental types of aquatic systems. Ability to apply knowledge and understanding. Knowing how to use the notions learned in class and developed in the exercises to interpret structures and functions of the different aquatic organisms and to solve problems in the various fields of field and laboratory applications. Judgment autonomy. Being able to identify the theoretical and experimental paths to be applied to the resolution of new problems even if similar to those discussed in class. Communication skills. Students' ability to talk, reason and discuss the questions raised during the lessons on the topics will be stimulated. Learning ability. Being able to discuss scientific issues concerning environmental monitoring activities and in general the academic ecology of aquatic environments also in its management applications and in its theoretical and experimental implications. This skill will be developed and tested by involving students in classroom discussions.

The course will give a comprehensive view on environmental contaminants and cover basic topics in ecotoxicology from transport, fate, and chemical characteristics of contaminants to effects on multiple biological organization levels. The course includes the following elements: ecotoxicological theory, QSAR as tools in in xenobiotics behaviour, ecotoxicological working methods, training in theoretical problem solving of ecotoxicological issues
