Ecology
Brown algae have adapted to a wide variety of marine ecological niches including the tidal splash zone, rock pools, the whole intertidal zone and relatively deep near shore waters. They are an important constituent of brackish water ecosystems, and four species survive in fresh water.[6] Most phaeophyceae are intertidal or upper littoral,[6] and they are predominantly cool and cold water organisms that benefit from nutrients in up welling cold water currents and inflows from land; Sargassum being a prominent exception to this generalisation.

Brown algae growing in brackish waters are almost solely asexual.[6]
