Mediterranean wetlands include a wide variety of natural habitats such as river deltas, freshwater, brackish, and salt lakes and marshes. Wetlands cover 18.5 million hectares in the Mediterranean region and support high concentrations of unique species of plants and animals. Being among the richest ecosystems in the world, they are also the most threatened. Some of the most important elements of these ecosystems are primary producers since they provide a number of ecological services such as food, nursery habitats, or sediment stabilization, among others. As is the case of the clonal flowering seagrasses communities, which are considered one of the most productive and complex marine ecosystems.
The global change and warming of the seawater represents a serious threat to these communities in the Mediterranean and it may compromise their survival, with dramatic effects on Mediterranean ecosystem functioning, so studying how these communities respond to stressors such as temperature extremes, could help us to better understand the limits of these ecosystems and improve our management of vulnerable Mediterranean ecosystems.
