Chemosynthesis and succession of hydrothermal species

We aim to investigate the response of hydrothermal ecosystem to disturbance and its role in organic matter production in the deep ocean. Our focus is on the resettlement of populations of invertebrate species dominating the biomass.
What is the role of geochemical changes in the succession of invertebrate species over years? What are the habitat properties favouring or inhibiting the growth of symbiotic invertebrates? The chair team investigates these issues through in situ experimental approaches linking environmental variability and growth including a custom-made marking chamber for sclerochronology studies (Nedoncelle et al. 2014)(picture) and autonomous electrochemical sensors (Nedoncelle et al. 2015).
