MA1-533 - Association à Nemalion lubricum et Rissoella verruculosa

Association with Nemalion lubricum and Rissoella verruculosa

Classification des habitats EUNIS 2022

Descriptif de l'habitat

This association is characterised by a continuous belt of the two red algae species Nemalion lubricum and Rissoella verruculosa. This association is present all year round, although it develops fully in winter and spring. The Rissoella verruculosa alga is present on siliceous or dolomite substrata. Exceptionally, it can be found on calcareous substrata, but then it exploits the presence of siliceous fragments to attach itself. The main characteristic species are Nemalion lubricum, Rissoella verruculosa and Audouinella nemalionis. The fauna is very impoverished and is essentially composed of Chtamales; where the Rissoella are abundant and retain sufficient dampness between the thalli, the Hyale perieri amphipods can be found.
