Learning Objectives
Knowledge acquired: Basic knowledge of biological invasions,
being able to distinguish an alien species from an invasive one, and of legislations and management issues.
Competence acquired:
Acquisition and use of an appropriate terminology; basic tools to deal with the problem of biological invasions, adopting a multidisciplinary approach.
Skills acquired (at the end of the course): using the main tools for species risk assessment; identifying the principal connections between human activities and invasion biology; managing invasive alien species from a scientific, social and legal perspective; identifying the main problems caused by the invasive alien species.
Prerequisites
Ecology, Wildlife conservation
Teaching Methods
Lectures (Power point)/seminars/field excursions
Type of Assessment
Oral exam. Discussion of a Power point presentation prepared by the candidate on a topic of the course.
Course program
History of the discipline (from Elton to Davis). Theories, terms and basic concepts. Areas of origin, main vectors and pathways of introductions (e.g. ports, airports, nurseries, aquaculture, pet trade). Invasion steps (arrival, establishment, and invasion). Characterization of the invasive species and the more vulnerable areas. The role of behavior in the success of invasive species. Impacts (ecological, socio-economic, ecosystem). Management of alien invasive species (hierarchical approach: prevention, early detection and rapid response, mitigation and control). New molecular techniques for the early detection (e.g. environmental DNA). European and Italian regulations. Risk assessment protocols. Alien species and climate change. Forecasting models. The role of the wide public (social perception of the problem). Case studies with management indications from different environments (terrestrial, freshwater, marine).
