Functioning of aquatic ecosystems

This course should enable students to acquire in-depth knowledge of how aquatic ecosystems function, and to identify threats and vulnerability in the face of local pressures and climate change.

It will also enable students to 1) understand the specific features of benthic ecosystem functioning and the ecological roles of its components, 2) acquire in-depth knowledge of the functioning of aquatic ecosystems, 3) acquire knowledge of the impact of chemical and biological contaminants (toxic and pathogenic microalgae), climate change and anthropization on the functioning of aquatic ecosystems and on these components with socio-economic repercussions. This course will develop networks for monitoring the marine environment and the health of exploited marine animals, while addressing mortality issues.

• Acquire in-depth knowledge of the functioning of aquatic ecosystems
• Understanding the specific functioning of benthic ecosystems and the ecological roles of their components
• Understanding biogeochemical studies in aquatic ecosystems with carbon as a study model
• Acquire knowledge of the threats to marine and freshwater aquatic ecosystems (biological invasions, cyanobacteria and toxic microalgae blooms) in the context of global change, raising the issue of the vulnerability of these ecosystems.
• Understanding the functioning of the food web with its planktonic components and allelopathic interactions
• Focus on tools and objectives for monitoring the marine environment, with particular reference to Mediterranean lagoons, whether anthropized or not.
• Acquire knowledge on the impact of chemical contaminants, climate change and human activity on aquatic ecosystems, with a focus on microbial communities.
• The sea is a breeding ground for active and interesting molecules, requiring sustainable management of these resources.
• Acquire knowledge of marine environment and animal health monitoring networks
• Understanding the causes of mollusc mortality in an anthropized marine environment, with a focus on the action of pathogens.
