Summary: The article introduces a model called RETAIN-D for forecasting harmful algal blooms (HABs), which combines reverse time attention with a decay mechanism. The model improves temporal resolution, forecasting performance, and interpretability. The study shows that RETAIN-D outperforms other models in forecasting HABs and successfully captures the high variability and irregularities in the time series.

Summary: Climate change is causing an increase in severity, frequency, and distribution of harmful algal blooms worldwide. This study focuses on the factors influencing the formation of these blooms in eutrophic lakes, specifically the hydrodynamics of the lake, the vertical movement of algae organisms, and the ability of the organisms to form colonies. The researchers developed a model that incorporates both vertical transport and colony dynamics, with a focus on aggregation. The results indicate that wind-induced mixing is the main aggregation process, and the rate of aggregation is inversely proportional to algal concentration. These findings have direct implications for predicting harmful algal blooms and improving forecasts.

Summary: This study elucidated the molecular mechanism of acetylacetone (AA) in selectively inhibiting Microcystis aeruginosa by affecting key molecules such as ferredoxin and nonheme iron, which ultimately disrupted the physiological and biochemical processes of Microcystis aeruginosa and inhibited bloom formation. These findings provide new insights for better control of harmful blooms.

Summary: The study reveals that fish respond differently to cyanobacterial toxicity within and among species, possibly due to their distinct proteomic profiles. Rainbow Trout and Lake Trout show variations in the uptake and depuration of microcystins, providing new insights into our understanding of this field.

Summary: The compositions of microbial communities associated with blooms of algae in a storage reservoir in Macau were investigated. The study identified the dominant bacteria and virus types, as well as patterns of changes in bacterial numbers within the microbial community. Furthermore, the study elucidated how various water-related variables influenced the bacterial and viral communities, and the relationship between bacterial numbers and trophic status in the reservoir used for drinking water.

Summary: Toxic cyanobacteria blooms have worsened over the past three decades, impacting coastal and lake water quality worldwide. Research is ongoing to understand the factors driving ecological imbalances and the role of cyanobacteria-produced toxins. The goal is to develop strategies to restore water bodies to their pre-toxic bloom state and mitigate the blooms in the short term to allow affected communities to enjoy safe water resources.

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: This study is the first to report the detection of airborne anatoxin-a outside an aquatic ecosystem during a harmful algal bloom. The findings suggest that emission of ATX molecules or cyanobacteria containing ATX during HABs could pose a potential human health risk not previously examined.

Summary: The Lake in Central Park and Prospect Park Lake in New York City have extremely high levels of cyanobacteria and microcystin. These lakes have elevated levels of orthophosphate relative to dissolved inorganic nitrogen during summer months. Nitrogen consistently limits cyanobacterial populations while green algae are rarely nutrient limited. Adding public drinking water rich in phosphorus and to a lesser extent nitrogen significantly enhances the growth of cyanobacteria.

Summary: The study investigated the H2O2 concentration and water quality parameters in a large artificial lake near a metropolitan city, finding that the H2O2 concentration in summer was over three times higher than in winter. The lake produced more H2O2 during daylight hours compared to streams, with the lowest production rates in dark conditions. Exposure to external substances, such as heavy metals and antibiotics, increased the generation of H2O2, with antibiotics having a more pronounced effect.

Summary: This paper examines the optimal harvesting decisions of a salmon farmer facing the risks of harmful algal blooms and market uncertainties. The ability of salmon farmers to actively learn about the true risk of biomass loss has significant value and is influenced by the availability of frequent and reliable information.

Summary: The program inStrain is used to study genetic diversity in microbial populations, particularly in fecal metagenomes of newborn premature infants. Results show that siblings share more microbial strains compared to unrelated infants, and infants born via cesarean section harbor bacteria with higher nucleotide diversity than vaginally delivered infants, potentially due to hospital acquisition. InStrain can be applied to analyze microdiversity and strain comparison in any metagenomic dataset.

Summary: Attached algal and cyanobacterial taxa exhibit differences in exploiting and tolerating the diverse flow, irradiance, and temperature conditions of a river system, with small-scale variations impacting ecosystem-scale estimates and predictions for algal assemblage shifts under altered flow regimes. Two manipulative field experiments conducted in 2014 and 2015 using PAM fluorometry revealed taxon-specific responses to depth, temperature, and flow modifications, highlighting the need for further research on the effects of environmental conditions on algal communities.

Summary: The study evaluated the potential risk of bigheaded carps population growth and food web effects in different habitats of the Great Lakes using a model framework. Results showed that in the main basins of Lakes Michigan and Huron, the projected bigheaded carps population growth was low or negative, with negligible effects on most food web groups. In contrast, in Saginaw Bay and Lake Erie, the projected bigheaded carps biomass was significantly higher, impacting zooplankton and planktivorous fish groups negatively.

Summary: This study aimed to provide a comprehensive view of cyanobacterial blooms in Clear Lake, California, by evaluating the spatial heterogeneity and temporal dynamics of these blooms using various remote sensing tools. The results showed that the high resolution AUV and sUAS data analysis found the Critical Scale of Variability for cyanobacterial blooms to range from 70 to 175 m, finer than what is resolvable by the satellite data, indicating high spatial variability within each 300 m satellite pixel.

Summary: The study found that the transitions of Absconditabacteria, Gracilibacteria, and Saccharibacteria between environmental ecosystems and mammalian mouths/guts probably did not involve major episodes of gene gain and loss; rather, gradual genomic change likely followed habitat migration. The results inform our understanding of how little-known microorganisms establish in the human microbiota where they may ultimately impact health.

Summary: Comparative analysis revealed significant genetic differences between toxic and nontoxic Microcoleus strains, with toxic strains potentially having reduced metabolic flexibility and dependence on coexisting nontoxic strains. The study sheds light on metabolic and evolutionary discrepancies between toxic and nontoxic Microcoleus, aiding in the prediction and management of aquatic blooms.

Summary: In the face of global change and toxic cyanobacterial blooms, cyanobacterial transfer to estuaries is expected to increase, affecting animal and human health. To evaluate their survival potential, we compared the resistance to salinity shock between colonial and unicellular forms of Microcystis aeruginosa. Our findings suggest that colonial forms have a greater ability to cope with osmotic shock and can withstand higher salinities than their unicellular counterparts. This implies that M. aeruginosa may survive and proliferate in estuaries.
