Summary: China, as a global factory and trade power, faces significant invasion risks in its ports due to the discharge of ballast water from ocean-going ships, especially in the Yangtze River Delta, Pearl River Delta, and Southern Taiwan Province. The disinfection of ballast water can effectively decrease the level of invasion risk.

Summary: Global shipping contributes to the introduction of invasive species and parasites through ballast water and hull fouling. This study used cargo shipping records to identify the connectivity of shipping routes between ports in Ireland and other nations. The findings highlight the importance of certain routes in facilitating the spread of invasive species and provide a general framework for effective management.

Summary: This paper presents a method for quickly evaluating the living status of algae in treated ship's ballast water by using electrokinetic detection and separation in a microfluidic chip. The experimental results show that dead algae have a significantly lower moving velocity compared to living algae, with larger dead algae having a decreased velocity to zero. This approach provides a potential solution for port state control to detect living algae in treated ship's ballast water.

Summary: Global coastal aquatic ecosystems are negatively impacted by harmful aquatic species introduced through ships' ballast water discharge. A study comparing the abundance and diversity of phytoplankton managed by BWMS or BWE + BWMS to BWE alone found significantly lower phytoplankton abundance in samples managed by BWMS or BWE + BWMS. Ballast water managed by BWMS tended to have lower abundances of harmful phytoplankton species.

Summary: This study examined the abundance and diversity of bloom forming species in ballast water managed under the D-1 and D-2 standards. The results showed that the abundance and diversity of these species were significantly lower in ballast water managed under the D-2 standard, and there was no significant correlation between ballast water age and the abundance and diversity of bloom forming species.

Summary: The International Maritime Organization has adopted the Ballast Water Management Convention, which mandates vessels to manage their ballast water according to specific standards. A Bayesian network-based framework is proposed in this paper to model the feasibility of mobile ballast water treatment solutions and the results suggest that mobile systems are highly feasible. The operational and logistical feasibility are identified as the most important parameters.

Summary: The purpose of this research is to compare four indicative analysis devices against detailed microscopy for measuring the size class of organisms >= 10 to <50 mu m in minimum dimension. The results showed that the indicative analysis devices had high agreement when assessing ballast water samples, but lower agreement during laboratory tests. The devices also had a relatively high rate of false negative results during laboratory tests.

Summary: With climate change, habitat salinity is rapidly shifting globally. Invasive species from saline habitats have recently invaded freshwater habitats. The copepod Eurytemora affinis species complex has independently invaded freshwater habitats multiple times from saline estuaries on three continents. Surprisingly, natural selection has favored the same alleles across independent freshwater invasions, which is unexpected for polygenic adaptation. Factors such as population structure and genome architecture may contribute to rapid adaptation and parallel evolution. The findings from this study can provide valuable insights into mechanisms in other systems and adaptation in a changing planet.

Summary: With the BWM Convention in force, finding an efficient tool for organism detection is crucial for ballast water management. FlowCAM, compared with a fluorescence microscope, showed better performance in abundance measures and significant correlation. However, there were differences in counting results and lower recognition rates compared to the microscope, indicating the need for further improvement. Overall, FlowCAM has the potential to become a promising tool for ballast water analysis if instrumental sensitivity and biological characteristics are considered.

Summary: The study found that the grinding device (GD) had a removal efficiency of 100% for organisms larger than 100μm, and 93% and 87% for organisms smaller than 100μm in the PT and FST, respectively. The removal efficiency did not significantly change within 2 hours of passing through the GD, but remained above 99% for samples stored for 120 hours. Further research is needed to determine additional removal efficiency based on storage period after passing through the GD, but it may be used as a pretreatment device for ballast water management system.

Summary: Ballast water is a known pathway for introducing non-indigenous organisms, causing harm to the environment, economy, and human health. This study investigated the suitability of FlowCAM for detecting phytoplankton in land-based and shipboard ballast water management system tests. The results showed that FlowCAM had limitations in recognizing and estimating the abundance of certain species compared to a fluorescence microscope. However, for many other species or genera, the results from both methods were similar. Overall, considering the imaging capabilities and particle abundance measurement of FlowCAM, it may be a promising technology for ballast water management system type approval.

Summary: Ballast water-mediated bioinvasion poses a significant threat to aquatic ecosystems, particularly in port environments. A pilot study conducted in a tropical ecosystem revealed that bacterial community in the port underwent short-term changes during ballast water discharge (BWD). The increase in Vibrio alginolyticus and decrease in V. parahaemolyticus, as well as the reduction in total coliforms, were attributed to BWD. Shifts in bacterial diversity, such as the dominance of Bacteroidetes and gamma-proteobacteria after BWD, can have implications for the functional characteristics of the port.

Summary: This study compared the characteristics of disinfection by-products (DBPs) generated during the treatment of algal organic matter (AOM) and commercial glucose using different active substances. The results showed that a higher variety and concentration of DBPs were generated during the treatment of AOM, with brominated compounds being dominant. Treating glucose, however, posed potential environmental risks.

Summary: This study aimed to evaluate the reliability of new Compliance Monitoring Devices (CMDs) in indicating compliance with Regulation D-2 for ballast water management systems. The study also assessed the accuracy and precision of CMDs by comparing them with microscopy. The results showed that CMDs had higher accuracy (>80%) in estimating organisms in prepared challenge water samples compared to ballast water samples (>70%).

Summary: Through high-throughput viral metagenomics, this study investigated the dynamics of DNA viruses in tropical seawater. Bacteriophages were found to be the most abundant viruses, with consistent proportions at different sampling times. Cyanophages were most dominant in June, while other nucleo-cytoplasmic large DNA viruses (NCLDVs) had higher proportions in March and December. These findings provide insights for comparative analyses of marine viral communities and policy-making for marine life conservation in Chuuk State.

Summary: Preclinical data have shown that ALS-L1023, an herbal extract from Melissa officinalis, can reduce visceral fat and hepatic steatosis. In this study, we evaluated the safety and efficacy of ALS-L1023 as a treatment for non-alcoholic fatty liver disease (NAFLD). The results showed that ALS-L1023 could significantly reduce hepatic fat content and improve liver stiffness in patients with NAFLD, with no significant differences in adverse events among the study groups.

Summary: This study used metagenomics to investigate the interactions between microbial communities and environmental factors during harmful algal blooms (HABs) caused by Akashiwo sanguinea in the Jangmok coastal waters of South Korea. Specific bacterial species had complex relationships with the A. sanguinea bloom, while certain viruses were strongly and positively correlated with the HABs. The dynamics of microbial communities and environmental factors changed during the A. sanguinea bloom, with rapid turnover of microorganisms responding to ecological interactions.
