Abstract The Mediterranean Sea is among the three biodiversity hotspots of the world where
elasmobranchs are severely threatened. Elasmobranchs act as apex or meso-predators …

While the general diet of Mediterranean elasmobranchs has been widely studied, little is
known about food partitioning and competition among sympatric species, despite these …

Elasmobranchs are among the marine species more threatened by overfishing. Their
