Ostreopsis spp.: Morphology, proliferation and toxic profile in the North-West of Agadir (North Atlantic Ocean).
The distribution of benthic Ostreopsis species is poorly known in the Moroccan coasts. The current study is aiming to investigate: i) the distribution of Ostreopsis spp. cells on macroalgae and in the seawater column of the Cape Ghir area (North-West of Agadir) during the summer season of Ostreopsis...
