Posidonia oceanica

Posidonia oceanica materials are also used for making artisanal handicrafts and to enhance the dyeability of these materials requires a change in their wettability. In this article, we will show how to alter the wettability

Tropical seaweeds are often well defended owing to high levels of predation by fishes on tropical reefs 18,37 however, coldwater seaweeds also use chemical protection, mainly against sea urchins and crabs. A number of macroalgae from the Antarctic subcontinent possess chemical extracts that are deterrent to sea stars,38,39 amphipods,39,40 or fish,39 while Arctic algae have been screened for deterrency toward sea urchins and amphipods.41 Chemical defenses have also been detected in seagrasses, notably in the Mediterranean Posidonia oceanica whose extracts deter feeding by sea urchins and fish 42...

Finally, the impact of UV-B radiation on marine macrophytes has been mostly conducted on individual species and not on the whole community. The criteria to select species for experimentation/analyses have varied (a) they are key species due to their contribution to primary production, or because they create a habitat for other marine plants and invertebrates, as the seagrass Posidonia oceanica in the Mediterranean Sea [42,122], Laminaria beds in the North Sea [123], or Macrocystis on the Pacific coast of California [4], (b) they represent a high share of macroalgal biomass in the ecosystem, as Ulva in eutrophic coastal waters [124] and, (c) they are commercially important as Porphyra sp., Gelidium sequipedale, Macrocystis pyrifera or Chondrus crispus [30,38,125,126].
