Summary: This study systematically evaluated the capability of VIIRS data in detecting and classifying harmful algal blooms (HAB) in optically complex and sediment-rich waters along the coasts of the East China Sea. The study found that certain spectral bands provided better quality for HAB detection, and compared the performance of four HAB detection algorithms. However, the classification of specific algal species was limited by the lack of a critical band in VIIRS data.

Summary: Exposure to Prorocentrum lima can lead to lethality in the brine shrimp Artemia salina and induce detoxification responses to oxidative stress. Protein degradation and energy expenditure are considered as response mechanisms to exposure to P. lima. Exposure to okadaic acid may disrupt the molting and reproduction activities of brine shrimp.

Summary: Harmful algal blooms (HABs) in the East China Sea are experiencing changes due to global warming, eutrophication, and other factors. A model predicts that dinoflagellate blooms will become more frequent and intense in the next 30 years. Nutrient composition changes and accelerated warming associated with climate change are the main drivers. To prevent further intensification of dinoflagellate blooms, efforts should be made to reduce nitrogen inputs and maintain or increase silicate inputs.

Summary: Blooms of Prorocentrum donghaiense occur annually in the East China Sea coastal waters, causing damage to the ecosystem and hindering economic development. Dissolved organic nitrogen and phosphorus are found to be the key factors influencing the bloom and phytoplankton community structure.

Summary: The study reveals a potential key role of prokaryotic microbiota in coastal harmful algal blooms based on significant correlations between the microbiomes and physicochemical properties of seawater. The findings suggest a previously unidentified association between Vibrio proliferation and the Prorocentrum-dominated HAB, indicating a possible involvement of Vibrio-mediated DNRA in symbiosis with Prorocentrum.

Summary: The development of techniques that can detect multiple microalgae simultaneously is critical due to the variety of algae species that form harmful algal blooms (HABs). This study established a multiplex polymerase chain reaction (mPCR) method to diagnose three dominant algae species in the East China Sea. The mPCR showed good specificity, stability, and the ability to detect H. akashiwo, P. donghaiense, and K. mikimotoi.

Summary: This study reveals functional differentiation among different types of alkaline phosphatase (AP) and their ability to compensate for each other. These findings have important implications for understanding the diversity of AP and the phosphorus nutrient niche differentiation, physiological plasticity, and competitive strategy in phytoplankton.

Summary: This study aimed to evaluate the risk of HAB occurrence in a highly cultivated watershed and assess the effectiveness of N and P reduction practices in mitigating this risk. The results suggested that regulating P was more effective in reducing HAB risks in the watershed, while regulating N was more effective in controlling downstream HAB.

Summary: Harmful algal blooms are a global threat to marine ecosystems and human health. This study used translatome sequencing to investigate the molecular mechanisms of the Prorocentrum donghaiense algae. Through analyzing the translatome and proteome, the study found that up-regulation of energy and material production pathways in phosphor-rich conditions led to exponential growth of the algae in HABs. The researchers also demonstrated that mild translation delay using low concentrations of cycloheximide can control algal blooms without harming other aquatic organisms or humans.

Summary: The concentration of dissolved oxygen in aquatic systems plays a crucial role in regulating biodiversity, nutrient biogeochemistry, greenhouse gas emissions, and drinking water quality. Climate change and human activities have led to declines in dissolved oxygen in lakes, impacting the physical and chemical environment, as well as essential ecosystem services.

Summary: This study investigated the changes of zooplankton communities during a bloom of P. donghaiense in the coastal waters of southern Zhejiang Province, China. The results showed that the bloom could be divided into three major phases: growth, maintenance, and dissipation. The bloom had significant impacts on the abundance and species composition of zooplankton, particularly copepods.

Summary: The coastal region of the East China Sea is a hotspot for harmful algal blooms in China, with unique HAB species and distinct spatial distribution patterns identified. Some HAB species showed substantially elevated abundance at specific sampling sites, suggesting multiple-species HAB events may be occurring. This study represented the first application of ASV-based metabarcoding analysis in studying protist and HAB species in the ECS.

Summary: This study found that harmful algal bloom (HAB) caused by P. donghaiense can significantly inhibit the growth and photosynthetic activities of S. fusiformis embryos, especially at higher cell densities. The maximum relative electron transport rates (rETR(max)) and apparent photosynthetic efficiency (alpha) were lower in co-cultivated embryos than in monocultivation ones, and parts of the photosynthetic reaction centers of PSII in co-cultivated embryos were inactivated.
