To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,64...

The present study investigates through an integrated survey, for the first time in Greek shellfish market, the marketing distribution towards a new edible shellfish product that of the non-indigenous pearl oyster Pinctada imbricata radiata. The survey conducted through personal interviews on sector entrepreneurs/staff of the supply (i.e., shellfish...

Greece, recently produced a chondrichthyans checklist, including 34 sharks, 26 batoids and 1 chimaera. However, the conservation status of most species is relatively unknown due to the lack of data. Here, we collect data with the goal of assessing the conservation status for 6 highly threatened species, Glaucostegus cemiculus, Gymnura altavela, Rhi...

Information on the feeding habits of elasmobranchs is of fundamental importance to understand their ecological role in the ecosystem. The study area (Ambracian Gulf) is a semi-closed embayment in Western Greece, characterised by shallow depths, muddy bottom, high freshwater influx, and hypoxia phenomena. It is considered a hotspot for megafauna hos...

Collaboration with small-scale fisheries of the Ambracian Gulf sheds light on the understudied elasmobranch diversity of the area. The Ambracian Gulf, a semi-closed embayment in northwestern Greece, is characterized by peculiar abiotic conditions including seasonal thermal shocks, eutrophic conditions, hypoxia and anoxia in depths below 15m in the...

In the Mediterranean Sea more than half of elasmobranchs are facing high extinction risk. Batoids and sharks are jeopardized by human activities, in particular fishing. The Ambracian Gulf is a semi-closed basin in the north-west of Greece, and although is considered an area of high ecological importance, there are no studies on impacts of small-sca...

Non-indigenous fish species (NIFS) are spreading in the Mediterranean Sea, altering species assemblages and reshaping the marine ecosystems. Market-based approach has been promoted as a measure to limit the spread and damages by the NIFS and provide economic revenues to fishers. Understanding drivers of NIFS consumption and documenting consumers' h...

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...

Biological invasions are considered among the largest threats to native biodiversity. The Mediterranean Sea, connecting the Indo-Pacific and Atlantic oceans, is characterized as a global marine invasion hotspot, due to a multitude of human pathways and vectors such as shipping, aquaculture, tourism, and the opening of the Suez Canal, which have led...

The Mediterranean Sea is one of the most heavily impacted areas by biological invasions worldwide, with over 650 non-indigenous species (NIS) reported as established in 2019. Information about the distribution of NIS in the basin is often fragmented or non-existent due to factors such as lack of finance, expertise, and appropriate surveillance syst...

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...

Raising knowledge of the dispersal of non-indigenous species (NIS) in new geographic areas is a matter of major concern, as alien species may outcompete the native biota through competition, predation, and hybridization. In the Mediterranean Sea, where biological invasions constitute a serious threat, the combined use of citizen science and social...

Greece exhibits the lowest seafood per capita consumption amongst European Mediterranean countries, and the investigation of consumer attitudes to new seafood products would bridge the gap among producers and consumers by promoting the vertical integration of the supply chain. However, limited information exists about consumer preferences for bival...

Crested oarfish Lophotus lacepede Giorna, 1809, is widely distributed in the mesopelagic zone and sometimes are accidentally collected as bycatch in commercial fishing practices. In this study, we add yet another record of this bathypelagic species in the Greek Seas, while the documented occurrence of the species is also reviewed for the entirety o...

The occurrence of two ribbonfish species, Zu cristatus (Bonelli, 1819) and Trachipterus trachypterus (Gmelin, 1789), in the Greek seas was examined through contributions made to the citizen-science project «Is it Alien to you…. Share it!!!». In total, 8 sightings, 2 for Z. cristatus and 6 for T. trachypterus were reported in various locations throu...

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 the Mediterranean Sea, Lobotes surinamensis (Bloch, 1790) is considered as a rare species, albeit an increasing number of individual-based sightings published in the literature. In this study, we present 32 additional records of this thermophilic species from the Greek and Cypriot waters; reinforcing the evidence that the species is becoming mor...
