Description: 

The warm-temperate Mediterranean is one of the remnants of Tethys, the ancient ocean than once long ago allowed worldwide dispersal of tropical and subtropical marine organisms. Although most of that biodiversity vanished in the late Miocene, 5.5 million years ago, some Tethyan species still survive in the Mediterranean, as seagrasses whose closest relatives occur in Australia, and sturgeons related to those found in the Aral Sea. These survivors of Tethys share the Mediterranean with newcomers that colonized the basin after the last Ice Age, like the monk seal, the loggerhead sea turtle, and the sperm whale. This course will explore the origin and characteristics of this amazing biodiversity and the dynamics of the ecosystems where these species thrive. But the Mediterranean is also one of the most densely populated areas in the world and one of the most attractive destinations for European tourists. Overfishing, pollution and destruction of coastal areas threaten the conservation of marine wildlife. The course will also consider the impact of these activities and whether sustained development can be achieved in the region. (3 credits)

Attendance policy: 

Attendance is mandatory for all IES classes, including field studies. Any exams, tests, presentations, or other work missed due to student absences can only be rescheduled in cases of documented medical or family emergencies. If a student misses more than three classes in any course half a letter grade will be deducted from the final grade for every additional absence. Seven absences in any course will result in a failing grade.

Learning outcomes: 

By the end of the course, the students are able to:

·         Recognise the major components of Mediterranean marine ecosystems

·         Describe the dynamics of Mediterranean marine ecosystems

·         Analyse the impact of human activities on Mediterranean marine ecosystems

·         Value marine biodiversity and the need for sustainable development.

Method of presentation: 

·         Readings: with the basic goal of give students an overview of the characteristics of Mediterranean marine ecosystems and the consequences of human activities.

·         Homework: to identify the key points of the readings and facilitate discussion during class

·         Lectures: to discuss and share different point of view and settle basic concepts

·         Field studies and classes on-site: to get some hands-on experience!

·         Term paper and oral presentation: to give students the opportunity to show what they have learnt. They will have to analyse and interpret information about different topics.

Field study: 

Visit to Barcelona Aquarium 

(on a Friday) Full day trip to Delta del Ebro

Required work and form of assessment: 

The final grade will be determined as follows:

·         Class participation and homework (15%): to guarantee that students are familiar with the topics covered in class, and their involvement in class activities

·         Field study (15%): This activity is essential to gain a deep insight into some of the topics covered by the course. There is one field study to Ebro Delta, on Friday. Attendance to the field studies is mandatory (see IES attendance policy). Furthermore, the students will take a quiz after the field study, based on a questionnaire available at the web site of the course. The answers to the questionnaire will be given during the field studies.

·         Midterm exam (20%) and Final exam (25%): a set of multiple choice and written questions to evaluate whether students are familiar with the basic topics discussed in class

·         Term paper and oral presentation (25%): to assess the capacity of students to integrate analyze, compare, and present information.
