81999 - RELAZIONI TRA BIODIVERSITA' E AMBIENTE

Course Unit Page

Academic Year 2017/2018

Learning outcomes

After completing the course, the student will know how organisms interact, as components of the structure and function of ecosystems, including the consequences of human interactions with the environment in general, and the marine system in particular. They will know the effects of global climate change on key organisms, biodiversity and ecosystems, particularly on marine species, including the effects on human societies and economies . Models and forecasts are presented considering different ocean warming and acidification scenarios predicted by the IPCC (Intergovernmental Panel on Climate Change).
