Harmful algal blooms (HABs) caused by lake eutrophication and climate change have become one of the most serious problems for the global water environment. Timely and comprehensive data on HABs are essential for their scientific management, a need unmet by traditional methods. This study constructed a novel digital twin lake framework (DTLF) aiming to integrate, represent and analyze multi-source monitoring data on HABs and water quality, so as to support the prevention and control of HABs. In this framework, different from traditional research, browser-based front ends were used to execute the video-based HAB monitoring process, and real-time monitoring in the real sense was realized. On this basis, multi-source monitored results of HABs and water quality were integrated and displayed in the constructed DTLF, and information on HABs and water quality can be grasped comprehensively, visualized realistically and analyzed precisely. Experimental results demonstrate the satisfying frequency of video-based HAB monitoring (once per second) and the valuable results of multi-source data integration and analysis for HAB management. This study demonstrated the high value of the constructed DTLF in accurate monitoring and scientific management of HABs in lakes.

Marine heatwaves (MHWs) are increasing in frequency and intensity worldwide, significantly impacting marine ecosystems. However, studies on phytoplankton community changes in coastal waters under such conditions remain. In the summer of 2024, an extreme high-temperature event (>28 °C) occurred in the southern coastal waters of Korea, providing an opportunity to investigate phytoplankton community dynamics under thermal stress.

The coastal waters of Qinhuangdao are a major hotspot for harmful algal blooms (HABs) in the Bohai Sea, with being one of the primary algal species responsible for these events. A comprehensive understanding of the microbial community structure and functional responses to bloom events is crucial for elucidating their underlying mechanisms and ecological impacts. This study investigated the microbial community dynamics, metabolic shifts, and the environmental drivers associated with a bloom in the coastal waters of Qinhuangdao, China, using high-throughput sequencing of 16S and 18S rRNA genes, co-occurrence network analysis, and metabolic pathway prediction.

Phaeocystis globosa is broadly distributed across tropical and temperate oceans, exhibiting substantial genetic and phenotypic diversity. This species plays a critical role in the global carbon and sulfur biogeochemical cycles, and is associated with harmful algal blooms (HABs) in eutrophic waters, particularly in Southeast Asia and the North Sea. Although extensively studied in the South China Sea due to recurrent HAB events, its genetic diversity, geographic distribution and environmental adaptations remain poorly understood in other coastal regions of China.

(Raphidophyceae) is a cosmopolitan species frequently associated with harmful algal blooms (HABs) and fish mortality events, representing a potential threat to aquaculture and coastal ecosystems. This study provides the first comprehensive morphological, phylogenetic, pigmentary, and toxicological characterization of strains isolated from Argentina. Light and transmission electron microscopy confirmed key diagnostic features of the species, including anterior flagella and the conspicuous group of mucocyst in the posterior region.

To evaluate the ecological risk of the toxic dinoflagellate Alexandrium tamarense on juvenile Mytilus galloprovincialis, mussels with an average shell length of 19.07 ± 1.38 mm were exposed to 500, 1250, and 4600 cells/mL of A.
