Elasmobranchs are highly threatened globally; 25% of species are estimated to be endangered by the IUCN. This disturbing trend is more significant in the Mediterranean, where over half of the species represented in the basin are at risk. Yet, there is still a considerable knowledge gap about distribution, abundance, and critical habitats of Elasmob...

Chondrichthyans are apex predators influencing the trophic web through a top-down process thus their depletion will affect the remaining biota. Notwithstanding that, research on chondrichthyans is sparse or data-limited in several biogeographic areas worldwide, including the Levantine Sea. We revise and update the knowledge of chondrichthyans in Cy...

In waterbirds, formation of mixed-species aggregations has been attributed to social facilitation and might also allow birds to exploit the ability of other species to make prey more accessible, to reduce their own time or effort spent in foraging and correspondingly increase foraging efficiency. However, some participants in mixed-species flocks m...

The distribution of marine life has been alarmingly reshaped lately and the number of non-indigenous species and their impacts are rapidly escalating globally. Timely and accurate information about the occurrence of non-indigenous species are of major importance for the mitigation of the issue. However, still large gaps in knowledge about marine bi...

Elasmobranchs, extremely charismatic and threatened animals, still are an important economic source for fshers in many parts of the world, providing signifcant income through trade. Even though Greek seas host at least 67 elasmobranch species, our knowledge about their biology and ecology is to a large extent unknown. In the present study the integ...

1. All three species of angel sharks (genus Squatina) inhabiting the Mediterranean Sea are listed as Critically Endangered in the International Union for Conservation of Nature Red List of Threatened Species due to overexploitation. 2. New records from Cyprus, Greece, Italy and Libya were collected from citizenscientists and integrated with local k...

In the present article, new records are given for 18 species (6 native, 9 alien and 3 cryptogenic), belonging to 5 Phyla (i.e. Chlo-rophyta, Cnidaria, Annelida, Mollusca and Chordata), from 8 Mediterranean countries: Spain: A large population of Polycerella emertoni reported from the Ebro Delta, the presence of Spinimuricea klavereni is confirmed f...

Two guitarfish species exist in the Mediterranean, the common guitarfish (Rhinobatos rhinobatos (Linnaeus, 1758)) and the blackchin guitarfish (Glaucostegus cemiculus (Geoffroy Saint-Hilaire, 1817)). Both species are listed as Endangered in the global, as well as the Mediterranean, assessment of the IUCN Red List of Threatened Species due to the st...

The alarming state of sharks and rays in the world and specifically in the Mediterranean Sea Is well known. In order to create effective conservation plans, basic ecological data such as distribution, and abundance are needed. For elasmobranchs, a large gap currently exists between the risk assessments and the basic ecological knowledge, though cru...
