The importance of Maërl Beds in subtidal seabeds.A mosaic of seabed habitats was determined by the variations of sediment grain size, which enhances local macrofaunal diversity. Maërl beds were characterized by high diverse assemblages, with intermediate values between seabeds colonized by Cymodocea nodosa and Garden eels (High) and sandy bare seabeds (Low). The characterization of maërl beds is important to understand the ecosystem functioning of this fragile and slow-growth ecosystem that could be affected by anthropogenic disturbances in the near future (harbours, pipelines, desalination plants, fish cages, etc.).

What about alpha and beta diversity of sandy seabeds of the Canary archipelago?. A mosaic sandy seabeds is present in the Canary Islands (Cymodocea nodosa meadows, Caulerpa spp meadows, eel grass, maerl, sabellid fields and unvegetated substrates) and thus a variety of different macroinfaunal assemblages are reported. Cymodocea and Caulerpa meadows, as well as, Sabellids fields harbour more diverse communities than non-vegetated seabeds. Moreover, a latitudinal gradient can be observed in the Canary archipelago, from eastern to western islands. Thus, Lanzarote and Gran Canaria (eastern islands) were characterized by higher diversity values compared to La Palma (western island). Have a look for more info! Monterroso, O., R. Riera & J.
