Abstract

In the Mediterranean Sea the co-occurring sea urchins Paracentrotus lividus and Arbacia lixula are usually consideredto share the same ecological role in the formation of barren from Cystoseira canopy. However, their foraging abilitymay vary due to feeding behavior and species-specific morphological traits. The relative effects of P. lividus and A.lixula on Cystoseira canopy was tested experimentally both in the laboratory, at a density of about 20 ind./m2, and in thefield by gut content analysis. Results, both in the field and in the laboratory experiments, show that A. lixula is unable toaffect Cystoseira spp. Furthermore, these results confirmed the great ability of P. lividus to consume Cystoseira canopy,thus supporting the evidence of the major role of this species in the creation of barren state
