Acclimation is a response that results from chronic exposure of an individual to new environment. This study aimed investigate whether the thermal environment affects early development seagrass Posidonia oceanica, and effects field-simulated Marine Heat Wave (MHW) on seedlings change depending acclimation. The experiment was done in field using crossed design (acclimated vs unacclimated) MHW (present absent) factors. has initially constrained P. oceanica seedlings, but then it increased their resilience MHW, under both morphological biochemical (fatty acid saturation) level. treatment could be considered restoration projects climate change-impaired sea, by purposely inducing resistance heat before transplants.
