David Mouillot proposes an analysis of the coral reefs in terms of biodiversity and productivity. He tries to explain the importance of the coral environments for the development of wide food webs, which can be durably used by the human populations of the concerned coastlines.

In this presentation, Jérémy Lobry defines the ecological features of the estuarine environments, which are transition areas between the ocean and the continental environment. He firstly highlights the quite poor biodiversity, and secondly the extremely important secondary productivity of those environments.

Audrey Darnaude shows us the role and the importance of the lagoons for the functioning of the biodiversity. Thanks to examples in the Lion Gulf, she explains that the coastal productivity is closely linked to those ecosystems.

Philippe Cury explains how the overfishing affects the marine food webs, and he highlights some ecological consequences of this practice, like the jellyfishes proliferation or the disappearance of the predatory species of the sought species.
