TEACHING METHODS The module consists of lectures and exercises done in the classroom. Lectures in the classroom are delivered through multimedia presentations. As there is no reference text adopted, class attendance is strongly recommended. The student can make use of the material made available on Aulaweb. Classes will be carried out in presence, and all face-to-face activities will be carried out in compliance with the current legislation following the emergency COVID19, and its further updates. Exercises are carried out regularly in the classroom for the application of the acquired knowledge, attendance at lectures and exercises is thus strongly recommended. The exercises also constitute a self-evaluation test. The planned exercises are: Exercise 1: Connectivity Exercise 2: Polygonal Exercise 3: Transect topography Exercise 4: Habitat suitability lagoons Exercise 5: Posidonia density Exercise 6: Phenology and epiphytism Posidonia Exercise 7: Transect bionomy Please refer to the specific AulaWeb application for this module for any updates due to changes in the health and epidemiological situation, and for all the other updates.

Class schedule SEASCAPE ECOLOGY EXAMS EXAM DESCRIPTION The exam consists of an oral test. The exam will begin with the exposure of a scientific article provided in the material for further study (exposed with a short digital presentation, in power point or similar, of about 5 minutes), and will continue with further 2/3 questions posed by the lecturer on topics covered during the module. There will be two exam sessions in the winter session (January-February) and five exam sessions in the summer session (June, July, September). Please refer to the AulaWeb specific module for any updates due to changes in the health and epidemiological situation and for all the other updates. ASSESSMENT METHODS Details on how to prepare for the exam and the degree of detail required for each topic will be provided at the beginning of the module and confirmed during classes. The oral exam will mainly focus on the topics covered during the lectures and will aim to assess the achievement of the appropriate level of knowledge. The ability to present the topics clearly and with correct terminology will also be evaluated. The oral exam starts from the critical report on a scientific article (among those provided and available on Aulaweb, introduced with a short presentation) to evaluate the ability to understand a scientific text dealing with marine seascape ecology and to elaborate landscape information based on the knowledge of the fundamentals of subject, on the propensity to link the various topics, and the application aspects. The completeness and correctness of the exercises proposed during classes will also be positively evaluated to those who will have done them and will take them to be evaluated during the exam.
