    Cetaceans - Can they be indicators of the state of the Black Sea environment?
    (Plovdiv University Press Paisii Hilendarski, 2025-03-26) Zaharieva, Zornitsa
    Anthropogenic pollution affects marine ecosystems worldwide, including the Black Sea. Heavy metals accumulation in animal tissues is crucial for monitoring ecosystem health. As top predators, cetaceans can serve as indicators of marine conditions. This study examines five heavy metals (Pb, Cd, Zn, Cu, Ni) in tissues of two Black Sea cetaceans and three fish species, constituting the their diet. Zinc showed the highest concentration in all studied samples. The Biomagnification factor (BMF) results indicate biomagnification in the cetaceans samples for the elements Cd and Zn.

    How stressed are two populations of the Mediterranean mussels (Mytilus galloprovincialis Lamarck, 1819) from the Black Sea (Bulgaria)? - Stress on stress biomarker responses
    (Plovdiv University Press "Paisii Hilendarski", 2025-01-15) Yancheva, Vesela; Georgieva, Elenka; Stoyanova, Stela; Todorova, Borislava; Antal, Laszlo; Nyeste, Krisztian
    This article aims to present the latest results on the stress on stress responses in farmed and wild mussels from Sozopol, Bulgaria, focusing on the autumn season of 2024. Additionally, we compare these findings with the results from the other three seasons.

    Stress on stress response in wild and farmed Mediterranean mussels (Mytilus galloprovincialis Lamarck, 1819) from Sozopol, Black Sea (Bulgaria)
    (Plovdiv University Press "Paisii Hilendarski", 2024-06-11) Yancheva, Vesela; Velcheva, Iliana; Georgieva, Elenka; Stoyanova, Stela; Todorova, Borislava; Nyeste, Krisztian; Antal, Laszlo
    As a continuation of our previous research, wild and farmed mussels from the town of Sozopol, located on the Southern Bulgarian Black Sea coast, were collected to assess and compare the survival rates (stress on stress response, SoS) as a biomarker for the multi-stressor environment. This time we aimed to investigate further if there could be any seasonal differences. Overall, the mussels collected in April had a longer survival time than those collected at the end of January 2024. However, the survival time of wild and farmed mussels had a shorter survival rate in the air than in other studies. The answer to the question “Why is that?” persists.
