Prerequisites: No prerequisites are required to attend the course.
Target skills and knowledge: The course will introduce the students to the study of marine organisms and their life history traits in relation to exploitation. Biological characteristics can make a species more or less vulnerable to exploitation, habitat modifications, changes in trophic webs. Attending this course, the students will achieve knowledge to evaluate the modalities of marine resource exploitation and the consequences of the exploitation on marine populations and ecosystem functioning. The students will achieve thoeretical and practical tools to independently estimate the life history traits of marine organisms in order to evaluate the species vulnerability and develop management strategies.
Examination methods: The final exam is written, consisting in three questions.
Assessment criteria: The first two questions deal with the different topics of the course, and will allow to evaluate the theoretical knwoledge achieved by the students. The third question will be a case study and will allow to evaluate the discriminating ability of the students in applying theoretical kwnoledge to case studies.
Course unit contents: Marine resources. Marine species and their exploitation. Marine organisms and ecosystem, ecosystem services. Consequences of species exploitation on marine ecosystems.
Life cycles and vulnerability of marine organisms. Traits of life cycle and exploitation. Growth. Reproduction: sexual maturity, sexual pattern, fecundity e fertility, mating system, reproductive sites and aggregations, parental care. Recruitment. Social systems. Distribution. Migrations.
Allee effect: occurrence of Allee effect in marine species and consequences in relation to exploitation.
Trade-off in life history traits: growth/reproduction; fecundity/offspring size.
Evolution of life history traits under fishery pressure.
Evaluation of the status of marine resources. IUCN Red List: criteria and categories.
Planned learning activities and teaching methods: The course includes theoretical and practical lessons. Thoeretical lessons will give the theoretical bases on the characteristics of the life cycle of exploited species and on the methods used to study life history traits. Theoretical lessons will be supported by practical laboratories that, through the direct collection and/or analyses of data, will allow the students to directly apply the theoretical basics to case studies. Laboratories will be carried out in the teching lab, collecting data on fish or invetebrate samples, and in the computer room, using softwares for data analyses. A survey at the Fish market of Chioggia will allow the evaluations of local marine resources.
Additional notes about suggested reading: Single books including all the topics are not available. The suggested books should be considered as support. All teaching slides as well as general and specific papers will be provided by the teacher.
