Effects of local and global changes linked to human activities on lagoons and marine coastal ecosystems
Marine coastal ecosystems gather 1/3 of world ecological resources of the Biosphere but are under increasing anthropic and environmental pressures. Lagoons, which cover more than 13% of the world shoreline, contribute highly to coastal zones’ productivity. However, lagoons are among the most fragile coastal ecosystems and the most threatened by human activities.
| In this context, the “Lagoon Ecosystems” joint research unit (ECOLAG, UMR 5119) focuses its research activities on the study of the “effects of local and global changes linked to human activities on lagoons and marine coastal ecosystems”. Because of their positioning at the sea-continent interface, these ecosystems are involved in major economical and ecological human activities: fishing, aquaculture, water cleansing, etc. The study of the biological functioning of lagoon and marine coastal ecosystems implies an integrative approach combining, at various scales (local, global), the characterisation of all main biological, physical and chemical components, the analysis of their interactions and the related functions.For this, the staff of the UMR 5119
carries out both in situ studies and mesocosms experiments, using a
large range of analytical tools and methods (molecular biology,
biogeochemistry, cytometry, etc). The UMR 5119 is composed of 19
lecturers, 24 research scientists (from the CNRS, Ifremer and IRD
institutes), 16 technical assistants and 22 PhD students split into 6
research teams. |
