Article Synopsis
  • Biodiversity is crucial for ecosystem health, and Greece, despite its small size, has a rich variety of freshwater fish species.
  • The study utilizes DNA barcoding by sequencing a segment of the COI gene from 406 fish specimens to assess the accuracy of current species classifications against molecular data.
  • Results indicate effective species identification for 55 out of 72 species, revealing cryptic diversity in some cases and region-specific genetic variations, highlighting the importance of further research on Greek freshwater fish biodiversity.

Pollution with copper (Cu), lead (Pb), zinc (Zn), chromium (Cr), and nickel (Ni) heavy metals of the surface sediments collected from three semi-closed East Mediterranean Gulfs, namely Kavala, Strymonikos, and Ierissos Gulfs, North Aegean Sea, Greece, was investigated to evaluate potential benthic ecological risks. The mean concentrations of the studied metals decrease according to the order: Zn > Pb > Cr > Ni > Cu (176.50, 166.

Surface sediment samples from Strymonikos and Ierissos Gulfs were analyzed for Cu, Pb, Zn, Cr and Ni. The results showed that the sediment of Ierissos Gulf is more polluted with Cu, Pb, and Zn as compared to that of Strymonikos Gulf. The benthal area located off the load-out facility of the mining operations in the town of Stratoni, in Ierissos Gulf is established as the most polluted region.
