Macrophytes of Running Waters: A Substrate for Algae and Fauna

WithEugene Angelier, James Munnick

Apart from benthic algae and lichens, the plant life of running water is made up of macrophytes: Bryophytes, Pteridophytes, and Spermatophytes. They are characterized by their various modes of anchoring themselves on the substrate, which determine their ability to resist the current. As for benthic fauna, the current determines the population, directly or by way of the substrate, but light also plays a significant role. Macrophytes in turn constitute a substrate for algae and fauna and help to protect them from the current.
