May 2019: Mesocosm dispersal experiment on Procambarus clarkii.
We will test in 28 mesocosms whether and how crayfish from marginal habitats (ponds in the Brière) differ from crayfish from the core habitat (Brière swamp) in terms of dispersal behaviour and response to density.
Collaborative project with Jean-Marc Paillisson and Eric Petit.

We will use the FlowCams to explore body-size structure and species assemblage in plankton communities.
Feb. 2019: Mesocosm medaka experiment
We will investigate in 52 mesocosms whether and how medaka having evolved in response to a 7-year exploitation history have different population dynamics and ecosystem effects than unharvested medaka.
