Seminar 1. Biological diversity. Explanation of the concept of biological diversity in the context of the Ecology and the Environmental Sciences, and calculate of different indices of diversity α, β and γ.
Seminar 2. Selection and organisation of the different works in group on diverse ecological subjects They will organise in groups to make works on diverse thematic of ecology
Seminar 3. European directives. Water Framework Directive and Habitats Directive. In this seminar will work with European directives that are in force in the actuality and help to comprise the ecological implications of these directives.
Seminar 4. Works groups and organization of different activities Seminar for doubts and advances with the works in group
Seminars 5. Gross primary production, net and respiration Practical seminar where will learn to calculate the gross primary productions, net and respiration of different ecosystems.
