Early detection and rapid response are essential to deal effectively with new introductions of invasive alien species (IAS). Citizen science platforms for opportunistic recording of species are increasingly popular, and there is potential to harvest their data for early detection of IAS, but this has not been tested. We evaluated the potential of d...

Accurate checklists of species are essential for evaluating their conservation status and for understanding more about their distribution, biology and ecology and, therefore, the first step in order to effectively protect them. According to the existing literature, the Greek seas are rich in chondrichthyan biodiversity and herein, we update the mos...

Angel sharks are among the most threatened species of sharks globally. Twenty-two species have been identified globally so far, with three species being present in the Mediterranean Sea: Squatina aculeata, Squatina oculata, and Squatina squatina. The Mediterranean populations of all three species have been assessed as Critically Endangered by the I...

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...

Elasmobranchs are sensitive marine species due to their K-strategic life characteristics in combination with the intensification of fisheries. Despite the regulations and conventions protecting several species, elasmobranchs are still caught as bycatch and landed throughout the Mediterranean, a location where the pressure on shark populations is we...

The goal of this report is to identify Critical Areas for Angel Sharks in the Aegean Sea

This report was produced within the framework of the Black Sea Basin funded project "Eco-Conscious Minds to Stop Pollution in the Valuable Wetlands of Black Sea Basin (BioLearn)

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...
