T4 : Adaptation to global changes in molluscs


The French common cuttlefish S. officinalis appears to be a relevant model to investigate the impact of global warming on marine mollusks. Indeed, two separated populations without any crossing reproduction or geographical overlap are living on the French coasts in the Mediterranean Sea and in the English Channel. The time shift of both life cycles reaches 6 months: 22-23 months in the English Channel vs. 16-17 months in Mediterranean Sea. 
Objective: To investigate the evolution of the expression pattern of the neuropeptides (quantitative transcriptomics and peptidomics) as the result of a temperature challenge. Two periods of the life cycle are targeted: just hatched juveniles and egg-laying females.
