Conservation and management of northeast Atlantic and Mediterranean maerl beds.
ABSTRACT 1. Maerl beds occur worldwide and are formed by an accumulation of unattached calcareous red algae (Rhodophyta). 2. Maerl-forming algae grow in a superficial living layer on sediments within the photic zone. 3. Maerl beds are spatially complex habitats with a high degree of species and trop...
