Abstract
Posidonia oceanica is a seagrass species thriving in the Mediterranean Sea since millennia. The integrity of P. oceanica meadows, in time and space, is essential to sustain the rich biodiversity of the Mediterranean, as well as to protect its shores and regulate the seawater’s chemical composition. As all seagrass beds worldwide, P. oceanica meadows are progressively regressing alongside with the increase of seawater temperatures caused by climate change. Multiple in situ and in vitro observations revealed the strong impact of warming on the persistence and fitness of the seagrass’ different life stages. The latter added to the impact of indirect actors such as sulfide stress, the synergies occurring between stressors and the high vulnerability of P. oceanica, worsens the status of the species in its rapidly changing environment. Nevertheless, some acclimation and/or adaptation possibilities seem to exist, for instance through the intensification of sexual reproduction and the activation of epigenetic processes. This literature survey gathers past and recent studies, giving a general picture of the diverse effects of global warming on P. oceanica. Although different trajectories for the fate of the meadows are proposed, all studies agree on the importance of protecting the meadows and acting for their conservation.
