Introduction : why a global ecology ?

Jérémy LOBRY

Junior researcher - Irstea Bordeaux - jeremy.lobry@irstea.fr

I am a junior scientist at Irstea in the "Aquatic ecosystem and global change" research unit. I am currently head of the “Functioning of Estuarine Ecosystems – FEE” research team. Even if my initial cursus was in fisheries ecology, I now focus on aquatic food webs, and, in particular, estuarine and coastal aquatic food webs. These systems, naturally stressed by strong morphological, hydrodynamics and sedimentary constraints, ecological communities are naturally characterized by features of low biodiversity. However, estuarine ecosystems are, at the same time, associated with many ecological functions, including a high biological production.

This leads to questioning the link between biodiversity and ecosystem processes in estuaries in order to address the difficulty to disentangle the effects of anthropogenic stress and natural constraints. In this context, my main purpose is to combine both community and ecosystem ecology through food web analysis and modeling in order to construct functional indicators of coastal and estuarine ecological status.
