Contribution of the course to the overall degree programme goals
The course "Ecology of coastal environments" intends to provide students with practical knowledge of applied ecology on ecological systems on a multidisciplinary scale, integrating biological, chemical, physical and sedimentological knowledge with applications and statistical elaborations. The topics covered are therefore transversal to various disciplines but concern all the marine-coastal areas and in particular the Transitional Water Systems (lagoons, coastal lakes, deltas) that have characteristics that are quite peculiar and intermediate between those of purely marine waters and environments of fresh water. In particular, trophic status and primary producers (aquatic phanerogams, macroalgae, phytoplankton, cyanobacteria) of these systems will be analyzed, examining the most important natural and anthropogenic factors that regulate their presence, biomass and productivity. Therefore the various impact factors will be analyzed (nutrients, pollutants, clams fishing and other factors that increase sediment resuspension, etc.) and their effects on the environment and ecological status.
The course includes 30 hours of lessons on these topics and 30 hours of laboratory divided into experimental tests of 5 hours each. The laboratory tests are intended to make known the various types of primary producers of coastal environments with ecological and systematic concepts. Furthermore, it intends to make known the most common practices of sampling of physico-chemical parameters and biological variables and to carry out some primary production measures, bacteriological determinations (colibacteria) and extraction of compounds by macrophytes useful for economic purposes (Agar, lipids, etc .).
Expected learning outcomes
1. Knowledge and understanding
1.1. Knowledge of this environmental typology;
1.2 Knowledge of the different primary producers with particular reference to phytoplankton and macroalgae that are not treated in any other course.
1.3. Knowledge of the differnt types of impact

2. Ability to apply knowledge and understanding
2.1. Know how to apply the most appropriate procedures to analyze every single problem

3. Ability to judge
3.1. know how to interpret the various parameters and environmental variables;
3.2. know how to identify the various environmental and sustainability indicators;
3.3. know how to give solutions to specific environmental problems.
Pre-requirements
Being a transversal course in different disciplines it is important for the students to have already done the basic courses of the various disciplines (Chemistry, Biology, Ecology, Sedimentology, Statistics, etc,)

Referral texts
Specific texts are not necessary because the topics covered are transversal to many disciplines and present procedures and data obtained from the various research activities. Specific texts in word and Power Point will be provided to the students
Assessment methods
The verification of learning takes place through a written test. The written test consists of 3 open questions for the purpose of ascertaining the skills acquired during the lessons and laboratory tests. During the written test the use of books, notes, electronic media is not allowed.
Teaching methods
Lessons are held in Word or Power Point files that are sent to students by e-mail at the end of each lesson. Furthermore, files of scientific articles on the main topics covered are provided.
Teaching language
Italian
