Description

Coralligenous habitats are remarkable marine ecosystems primarily found in the Mediterranean Sea. These habitats are created through a process known as “bioconstruction,” where various plant and animal organisms with calcareous skeletons build complex, three-dimensional structures. These formations are akin to tropical coral reefs and are highly valued for their rich biodiversity and ecological significance.

Typically developing at depths of 10 to 120 meters, coralligenous habitats thrive in low-light conditions that still allow the growth of coralline algae. These algae, along with other organisms like bryozoans and serpulids, are the main architects of these habitats. The resulting structures provide numerous microhabitats, making them hotspots of biodiversity.

Original Title

"Modelled Spatial Distributions of Coralligenous Habitats"

Description

"This dataset shows modelled spatial distributions of coralligenous outcrops across the Mediterranean Sea. These bioconstructions are typical Mediterranean underwater seascapes, comprising coralline algal frameworks that grow in dim light conditions. They are the result of the building activities of algal and animal constructors, counterbalanced by physical, as well as biological, eroding processes. Because of their extent, biodiversity and production, coralligenous habitats rank among the most important ecosystems in the Mediterranean Sea, and they are considered of great significance both for fisheries and carbon regulation."
