Summary: The study reports the spread of Streblospio gynobranchiata and the first occurrence of Laonome xeprovala in the Black Sea basin, showing that the former is considered a significant invader in Mediterranean soft bottoms while the latter is a new invader successfully settling in the Baltic and Azov Seas before reaching the Black Sea.

Summary: This study aimed to identify the morphotypes of Hysterothylacium larvae in the Black Sea using both morphological and molecular techniques. Four commonly edible marine fish species were analyzed, and their Hysterothylacium larvae were classified based on morphological and genetic data. This study provides the first report on the whole ITS and cox2 sequences of Hysterothylacium larvae in the Black Sea, laying the foundation for future research on their distribution and identification.

Summary: Potato is the third most important crop worldwide, with Meloidogyne luci, a tropical root-knot nematode, being detected parasitizing potato for the first time in the Azores islands of Portugal. Detailed characterization through morphological, biochemical, and molecular analysis was conducted, providing valuable information on the distribution of this plant-parasitic nematode.

Summary: The Jeokjung-Chogye Basin in Hapcheon, a 7 km-diameter impact crater in the southeastern Korean Peninsula, shows direct evidence of impact cratering for the first time, with unique impact-driven metamorphic features reported. The impact likely occurred during the last glacial period, providing an opportunity to reconstruct high-resolution paleoclimate changes and study shock metamorphism in a location experiencing significant weathering and erosion under tropical-temperate climate conditions.

Summary: This study investigated the occurrence, morphology, and identification of microplastics in Black Sea sediments at different depths using a non-invasive method. The research found that microplastics were present in 83% of sediment samples, with polyethylene and polypropylene being the most abundant plastic polymers, and fibers being the dominant type of microplastics in sediments.

Summary: The first out-of-brace radiograph is found to be the best predictor of the Cobb angle at the end of treatment, surpassing the in-brace radiograph. It serves as a valuable reference for clinicians and patients, and should be considered as an essential element in future predictive models.

Summary: Phosphorus (P) is a crucial element for all life and its cycling in sediment can vary depending on the redox conditions of the water above. This study investigated the biogeochemical cycling of sedimentary P in the Black Sea, Marmara Sea, and Northeastern Mediterranean Sea. The results showed significant variability in porewater and sediment biogeochemistry, with the highest concentrations of P and other nutrients found in hypoxic and anoxic areas. The study predicts that deoxygenation and eutrophication will lead to the release of P in these interconnected marine basins, affecting nutrient stocks and N/P control in marine ecosystems.

Summary: This study evaluates the impact of parasitic Ascaridoid Nematode larvae on the Black Sea anchovy population in the Southern Black Sea. The infection rate was higher on the western side of the study area, potentially serving as a biomarker for the western stock. Age and size of the anchovies are significant factors in infection rates, with parasitized fish showing lower health indicators.

Summary: Biological invasions can have major impacts on freshwater and marine ecosystems. This study reports the first occurrence of Marenzelleria neglecta and the spread of Laonome xeprovala in the Danube Delta-Black Sea ecosystem. Both species exhibit invasive behavior and colonize large areas in a short time period. Further research is needed to assess their impact on ecosystem structure and functioning.

Summary: The myxosporean parasite Ceratomyxa scorpaeni was identified in the gall bladder of the black scorpionfish Scorpaena porcus collected from the Black Sea coast of Sinop. Molecular analysis confirmed the parasite's identity as C. scorpaeni, marking the first report of its occurrence in the Black Sea.

Summary: The study reveals the distribution of dissolved black carbon in the Pacific Ocean, indicating a negative correlation between its concentration and deep-ocean circulation. The removal process of black carbon to abyssal sediments is estimated to account for a small percentage of anthropogenic CO2 uptake by the ocean.

Summary: Observations are crucial in exploring and understanding the ocean. The Red Sea Decade Expedition reported three observations of Firoloida desmarestia, a shell-less mollusk, for the first time in the Red Sea, indicating a global distribution for this species. The observations suggest a depth range expansion and raise questions about the species' behavior and vertical migrations. A literature search was conducted to understand the global distribution and ecological significance of this species.

Summary: For the first time, the ingestion and egestion of microplastics by copepods in the Black Sea was evaluated, along with the composition and concentration of microplastics in the water column. The study found that copepods in the Black Sea are contaminated by microplastics, which poses risks to their critical functions in the ecosystem. Additionally, copepods may act as vectors for the transfer of microplastics and associated toxic chemicals to higher trophic levels, including humans.

Summary: Based on bottom trawl surveys conducted in the Siberian Arctic seas in 2019, it was found that no seabed litter was detected in the East Siberian Sea and the Laptev Sea, while debris was only found in the Kara and Chukchi seas. Plastic was the most frequently occurring type of seabed litter, with the main source of garbage in the Kara Sea being related to fishing activities in the Barents Sea.
