“…The responses of phytoplankton and protozoa to chloride increases were group-speci c and depend on nutrient levels. The previous survey and identi cation results showed that Ankistrodesmus falcatus or Scenedesmus in Chlorophyta survived in the high-salinity ballast water, even though they were freshwater species (Wu, 2019). In this study, it was observed that Chlamydomonas sp.…”

In nowadays, world trade and cargo transportation mainly rely on shipping, and inland ports provide valuable and essential services to the maritime transport. With the increase of trade volume, the discharge of ballast water from ships is also increasing, which brings in ecological challenges. The International Maritime Organization stipulates that the number of organisms in discharged ballast water should be limited to prevent biological invasion to recipient waters. However, ballast water still contains many substances of source water, and may affect the plankton community in the recipient waters. In this study, the effects of ballast water on nature freshwater plankton community were evaluated at laboratory scale. It was observed that the abundance and diversity of planktons decreased with increase of water salinity. Through 10 days of continuous monitoring, it was found that ≥ 50 µm organisms were more sensitive to rising salinity than 10–50 um organisms, when water salinity was not over 3.6‰, there was no significant difference on ≥ 50 µm organisms quantity and diversity compared with the freshwater control group after 10 days, and the biota maintained certain recovery ability, while 10–50 um organisms had recovery ability when water salinity was not over 6.5‰. However, when the water salinity was over 6.5‰, both species composition and organism density showed irreversible and rapid reduction. In addition, organism species Platyias sp., Polyarthra sp., Tribonema sp., Navicula sp. were found to be very sensitive to salinity change and could be considered as indicative organisms for monitoring and evaluating ecological effect of discharge of saline ballast water. This is of great significance for the scientific management of ballast water discharge in fresh waters in the future.

“…Since the 1990s, China has been concerned about and studied the invasion of species carried by ballast water. WU et al measured the diversity and abundance of phytoplankton in ballast water of 26 ships in Yangshan Deepwater Harbor, Shanghai, from April 2015 to January 2016, and identified 84 species of phytoplankton, of which nine species were potentially harmful [8]. WANG et al investigated the abundance and diversity of species in red tide due to ballast water from ships in Yangshan Deepwater Harbor.…”

With the advancement of global maritime transport, the carriage of foreign organisms by vessels is inciting ecological catastrophes such as red tides, posing a grave threat to China's marine environmental security. Clarifying the geographical distribution of invasive species and their relationship with climate change can provide scientific basis for their prevention and control. In this discourse, the study centers on the typical alien microalgae, Nitzschiella closterium. By integrating environmental variables and distribution data and employing an optimized Maxent model, we delve into its potential distribution in current and future ecological conditions in the coastal waters of China, as well as the response relationship to environmental variables. After model optimization, the results reveal that the Area Under the Curve (AUC) value of the training dataset for Nitzschiella closterium stands at 0.993, denoting a high degree of model accuracy and bestowing credibility upon the simulated outcomes. Currently, the high suitability area constitutes 0.74% of the total suitability area, with an area of 0.44×10 4 km², and is mainly distributed in the sea area corresponding to Jiangsu Province, Shanghai City, and Zhejiang Province. The most significant environmental factor affecting the geographical distribution of Nitzschiella closterium is the annual temperature variation range (bio24). In the context of future climate changes, there is an overall trend of substantial expansion in the high suitability area for Nitzschiella closterium, which is profoundly affected by climate change, suggesting that the future control will be more severe. This research comprehensively understands the response relationship of the invasive species Nitzschiella closterium to leading environmental variables and its potential geographical distribution in the context of climate change through macro prediction and proposes control countermeasures. It will provide a scientific basis for preventing and controlling Nitzschiella closterium invasions.

Alien invasive algae along with ship ballast water have posed a serious threat to China's marine ecological security. A clear understanding of the geographical distribution of invasive species and their response to climate change can provide a scientific basis for their prevention and control. In this study, combined with environmental variables and distribution data, MaxEnt was used to predict the potential geographical distribution and change trend of Alexandrium in the four major sea areas of China currently, 2040s (2040-2050) and 2090s (2090-2100), reveal the dominant environmental factors affecting the geographical distribution, analyze the migration trends of centroids the highly suitable area, and clarify the key control sea areas. The results showed that: 1) The AUC values of all models were significantly higher than random models, and the Kappa statistics of all models were higher than "general", demonstrated that the prediction results were available.2) The most important environmental variable affecting the geographical distribution of Alexandrium was the Temperature. Range (bio24), and its suitable range was 23.43-31.52ºC. 2) At present, in the corresponding sea areas of Nantong,
