Floating <em>Ulva prolifera</em>, the primary species driving the Yellow Sea green tide, exhibits morphologically indistinguishable sporophyte and gametophyte stages. This study is the first to systematically explore the growth and reproductive characteristics of <em>U. prolifera</em> sporophytes and gametophytes. The growth rate of gametophytes was significantly higher than that of sporophytes, while sporophytes demonstrated higher spore release capability, showing no significant correlation with temperature. Analysis of 756 floating <em>U. prolifera</em> specimens collected from the Yellow Sea from 2022 to 2024 revealed that the dominant type varied annually: mixed sporophytes and gametophytes in 2022, a predominance of gametophytes in 2023, and sporophytes in 2024. However, the dominant type remained consistent across different survey periods within each year. Given that <em>U. prolifera</em> exhibited a higher probability of in-situ germination in laboratory cultures than in the field, we inferred that floating <em>U. prolifera</em> might employ different reproductive strategies: primarily asexual reproduction in the laboratory and vegetative reproduction in the wild. Through statistical analysis of annual algal types and green tide parameters, we found that the dominant algal type showed a weak correlation with green tide parameters, indicating comparable contributions of sporophytes and gametophytes to green tide formation without significant differences. This study provides new insights on the differences between stages in isomorphic haploid-diploid species analysis and the biological mechanisms behind green tide formation, offering important theoretical foundation for prediction and prevention research.</div></div>","PeriodicalId":18215,"journal":{"name":"Marine pollution bulletin","volume":"214 ","pages":"Article 117752"},"PeriodicalIF":5.3,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143547954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ecological model, coupled with a hydrodynamic model, simulates the nutrient cycle in the water column and in the sediment, the growth and decay of rooted vegetation, macroalgae, phytoplankton, and zooplankton, as well as the oxygen cycle. Once calibrated and validated with field measurements, the model has been used as a decision-support tool for lagoon management, providing qualitative insights into the impact of various stress factors and intervention actions.

Industrial productions, shipping activities, as well as ocean current transport appear to be key sources of PCBs in studied region, while the aerobic degradation of residual DDT likely explains the widespread presence of DDE. In sediment core, both ΣPCBs and ΣOCPs exhibited parabolic variation trends along the sediment core depth, reflecting historical use in the Beibu Gulf, with recent declines in new inputs.

This study used the diatom <em>Phaeodactylum tricornutum</em> as a model organism to assess the effect of each enantiomer on growth, photosynthesis, energy metabolism, and oxidative damage. The results showed that exposure of diatoms to <em>R</em>-propranolol induced growth inhibition due to deficiencies in photochemical metabolism, which was reflected in changes in the photosynthetic pigment profile. Oxidative stress also occurred in cells, resulting in lipid oxidation and DNA damage. In contrast, such effects were not observed for the <em>S-</em>enantiomer at the tested concentrations.

Furthermore, MPs are capable of carrying metals and organic pollutants that constitute composite pollutants. The additives it carries will gradually release harmful substances during the degradation process. Once ingested by aquatic organisms and amplified by the food chain, these pollutants can adversely affect the survival and growth of marine flora and fauna, ultimately posing potential threats to humans. In this review, the major sources and sinks of MPs are described, considering the pollution of marine ecosystems. Additionally, typical environmental behaviors of MPs including their migration and accumulation in the ocean, their combined ability with heavy metals and organic pollutants, their leaching of additives, and their abiotic and biotic degradation pathways are discussed.
