“…A significant issue for the aquatic food web is the eutrophication caused by high phosphate and nitrate concentrations. Algal blooms prevent phytoplankton and other organisms from receiving enough oxygen, leading to an organism's demise and to declining biodiversity and water body toxicity [66].…”

The paper contributes to the Sustainable Development Goals (SDGs) targeting Life Below Water by introducing user-friendly modeling approaches. It delves into the impact of abiotic factors on the first two trophic levels within the marine ecosystem, both naturally and due to human influence. Specifically, the study examines the connections between environmental parameters (e.g., temperature, salinity, nutrients) and plankton along the Romanian Black Sea coast during the warm season over a decade. The research develops models to forecast zooplankton proliferation using machine learning (ML) algorithms and gathered data. Water temperature significantly affects copepods and “other groups” of zooplankton densities during the warm season. Conversely, no discernible impact is observed on dinoflagellate Noctiluca scintillans blooms. Salinity fluctuations notably influence typical phytoplankton proliferation, with phosphate concentrations primarily driving widespread blooms. The study explores two scenarios for forecasting zooplankton growth: Business as Usual, predicting modest increases in temperature, salinity, and constant nutrient levels, and the Mild scenario, projecting substantial temperature and salinity increases alongside significant nutrient decrease by 2042. The findings underscore high densities of Noctiluca scintillans under both scenarios, particularly pronounced in the second scenario, surpassing the first by around 70%. These findings, indicative of a eutrophic ecosystem, underscore the potential implications of altered abiotic factors on ecosystem health, aligning with SDGs focused on Life Below Water.

The paper aims to introduce user-friendly modelling approaches to analyze how abiotic factors influence various trophic levels within the marine ecosystem, both naturally and through human impact. It specifically investigates the connections between environmental parameters (like temperature, salinity, and nutrients) and plankton along the Romanian Black Sea coast during the warm season (May-September) over a decade. Utilizing machine learning (ML) algorithms and data collected during this period, models were developed to project the proliferation of zooplankton. During the warm season, water temperature emerged as a significant factor affecting copepods and “other groups” zooplankton densities, while no discernible impact was noted on Noctiluca scintillans blooms. Salinity fluctuations notably influenced typical phytoplankton proliferation, with phosphate concentrations primarily driving widespread blooms. Two scenarios were explored for forecasting zooplankton growth: Business as Usual, predicting modest increases in temperature, salinity, and constant nutrient levels, and the Mild scenario, anticipating more substantial temperature and salinity increases while nutrients decrease significantly by 2042. The findings highlight that under both scenarios, Noctiluca scintillans displays notably high densities, with the second scenario projecting even higher values, surpassing the first by around 70%. These densities indicate characteristics of a eutrophic ecosystem, suggesting the potential implications of altered abiotic factors on ecosystem health.

“…Phytoplankton are the floating microscopic organisms, which serves as a primary food source for many aquatic living organisms and fish communities, is also an indicator of the wealthiest aquatic environment (Tiwari and Chauhan, 2006;Gokhale and Sharma, 2022;Sarker et al, 2023). Their communities are usually quite diverse, with typically several dozens of species.…”

Phytoplankton play a crucial role not only in primary production but also in nutrient cycling. Khadakwasla Reservoir serves as an important water source for the Pune City. By understanding the diversity and abundance of phytoplankton in this reservoir we can assess the ecological health and potential implications on water quality. The present study aimed to investigate the phytoplankton community in Khadakwasla Reservoir over a period of 21 months. Water samples were regularly collected on a monthly basis from four sampling stations across the reservoir. Qualitative and quantitative analysis of phytoplankton samples was done by using standard methods.The observed variations in phytoplankton abundance and composition may be attributed to various factors including seasonal changes and anthropogenic activities in the catchment area. Observations indicate prevalence of Chlorophyceae as the dominant group, followed by Bacillariophyceae, Cyanophyceae, and Euglenophyceae. Thus, the dynamics of phytoplankton in Khadakwasla Reservoir is vital for effective water resource management and to assess potential implications for water quality and biodiversity.
