Epiphytes impose physical barriers to light penetration into seagrass leaves causing shading, which may decrease the production of reactive oxygen species (ROS), but also constitute a physical aggression that may trigger the production of ROS, leading to oxidative damage. These adaptations control leaf self-shading and plant competition in well-established P. oceanica beds while also promoting increased seedling survival rates in open, uncolonised reports the baseline results and the status of Posidonia oceanica for two stations, which were monitored between 2018 and 2019.
