Sažetak
Current classification systems of marine habitats in the Mediterranean are based on homogeneous categories. However, the natural benthos is not homogeneous and there is a need to explicitly recognize and quantify the extent of habitat edges, the unique conditions and resources they offer, and the unique animal communities they support. We predicted that species seek edge habitats due to their predation mode or their ability to exploit more varied resources. We found a significant heterogeneity effect: edge habitats have higher fish abundance, species richness, and diversity than homogenous habitats. Species more abundant at edges have diets with significantly higher taxon diversity. Edge seeking species result in unique fish ssemblages. Management of fish biodiversity should recognize the conservation value of edge habitats.
