Abstract
Posidonia oceanica ecosystems are extremely complex and unique marine environments and they constitute one of the most valuable submerged ecosystems on the earth providing biomass, oxygenating the oceans, acting as major CO2 sinks and providing suitable habitat for hundreds of species. Over the last decades, following increased coastal urbanisation and industrialisation and the uncontrolled use of unsustainable fishing methods such as trawling, as well as the invasion of alien species have caused the disappearance and/or alteration of many P. oceanica meadows. Additionally, ocean warming, sea level rise, eutrophication and extreme weather events are climate change effects that are hampering P. oceanica recovery and, in most of the cases, speeding up their decline. Despite some conservation measures focused on the installation of artificial reefs and seagrass-friendly moorings for boats, scant attention has been devoted to palliate the effects of Climate change until recent times. This essay will explore the potential effects that climate change will have on P.oceanica by examining (i) the ecological and economic relevance of P. oceanica meadows in the Mediterranean ii) the current and historical known distribution across the Mediterranean Sea, (iii) the magnitude of decline phenomena in the last decades and its consequences, iv) climate change-related challenges and pressures for the upcoming years and (v) the conservation measures currently implemented.
