Special Issue Information

Dear Colleagues,

This Special Issue focuses on advancing our understanding of the dynamics of phytoplankton in eutrophic water systems. Eutrophication, driven by excessive nutrient inputs, has become a pressing global environmental issue, resulting in harmful algal blooms, oxygen depletion, and biodiversity loss. Phytoplankton, as primary producers and key indicators of water quality, play a pivotal role in the ecological processes of eutrophic environments.

This Special Issue invites contributions exploring the drivers, mechanisms, and impacts of phytoplankton dynamics in eutrophic waters. Topics of interest include, but are not limited to, the following:

  1. Factors influencing phytoplankton growth and community composition (e.g., nutrients, light, temperature, and hydrodynamics).
  2. Modeling and predicting phytoplankton blooms.
  3. Interactions between phytoplankton and other aquatic organisms in eutrophic systems.
  4. The effects of eutrophication on ecosystem functions and services.
  5. Innovative monitoring and mitigation strategies for controlling phytoplankton blooms.

We welcome original research articles, reviews, and case studies addressing these critical challenges. This Special Issue aims to provide a platform for interdisciplinary research that advances the sustainable management and restoration of eutrophic water ecosystems.

In Finland, municipal wastewater treatment has significantly improved in recent decades, leading to a substantial reduction in nutrient loads from wastewater discharged into water bodies. For example, in the marine area off Turku in the Archipelago Sea, located in the northern Baltic Sea, the total phosphorus load from wastewater has decreased to approximately one-eighth of its level in the early 1990s. Simultaneously, the total nitrogen load has been reduced to one-fifth, and the ammonium nitrogen load is now less than 5% of its peak in 1994. This study examines in detail how water quality parameters and phytoplankton indicators in wastewater-affected areas have changed during the same period in which wastewater loads have significantly decreased. This reduction has contributed to positive developments in the marine area off Turku, although the goal of achieving good ecological status remains unmet. In Raisio Bay, chlorophyll a concentrations decreased by 68% following the relocation of wastewater discharge. In Rauvola Bay, the reduction was estimated to be 36%. Over the past 15 years, the biomass of nitrogen-fixing cyanobacteria has increased in northern Airisto. This trend appears to be driven by a decrease in external nitrogen loading in combination with increased internal phosphorus loading. Water bodies in the inner archipelago continue to receive excessive nutrient inputs from the surrounding catchment area, while internal loading significantly delays the restoration process.

This study employs bibliometric analysis and knowledge mapping to examine trends in research on phytoplankton in Chinese reservoirs from 2004 to 2024. Utilizing the Web of Science Core Collection Database, the analysis focuses on studies related to reservoirs, phytoplankton, and cyanophytes in China. Three distinct stages in the evolution of phytoplankton research are identified: initial studies on lakes and eutrophication (2004–2010), a shift towards cyanobacteria blooms and their ecological impacts (2010–2015), and a recent focus on phytoplankton communities, carbon cycles, and nutrient cycles (2015–2024). Key hotspots such as nitrogen stable isotopes, reservoir management, lakes, and cyanobacterial blooms are identified. This study highlights a growing interest in environmental factors influencing ecosystems, biodiversity conservation, and nutrient status assessment. These findings provide a comprehensive understanding of phytoplankton research in Chinese reservoirs, revealing research hotspots, regional differences, and future directions. A collaboration network analysis among institutions and authors underscores significant contributions from the Chinese Academy of Sciences and key researchers. This study provides a foundation for future research, emphasizing the importance of addressing eutrophication, phytoplankton community dynamics, and ecosystem degradation in reservoirs. Full article
