Nutrients and not temperature are the key drivers for cyanobacterial biomass in the Americas

Sylvia Bonilla et al.

Summary: Cyanobacterial blooms pose a threat to freshwater use globally and present challenges for water management. While high temperatures and nutrient concentrations are believed to trigger blooms, the roles of nitrogen and phosphorus are still debated. This study analyzed data from lakes across a vast geographic range and found that phosphorus was the primary resource explaining cyanobacterial biomass, while temperature had a weak relationship. Shallow lakes were found to be more vulnerable to eutrophication.

Monsoon-induced response of algal chlorophyll to trophic state, light availability, and morphometry in 293 temperate reservoirs

Namsrai Jargal et al.

Summary: Eutrophication management is a major environmental challenge for lakes worldwide. This study examines the impacts of morphological and chemical variables, as well as the Asian monsoon, on the relationship between algal chlorophyll-a and total phosphorus. The findings show that the functional response of algal chlorophyll-a to total phosphorus is influenced by monsoon-induced changes in water chemistry and light attenuation.

Severe cyanobacterial blooms in an Australian lake; causes and factors controlling succession patterns

Jordan A. Facey et al.

Summary: This study found that thermal stratification and nitrogen availability are the primary drivers of changes in cyanobacterial community structure in Mannus Lake, Australia. The initial dominance of Chrysosporum ovalisporum blooms may be due to nitrogen limitation and persistent thermal stratification. However, mixing events caused the senescence of the C. ovalisporum bloom and promoted the growth of non-diazotrophic cyanobacteria, although at lower biovolumes.

Spatio-temporal characterization of nutrient and organic pollution along with nutrient-chlorophyll-a dynamics in the Geum River

Md Mamun et al.

Summary: River water pollution is a significant environmental challenge worldwide. Understanding the spatial and temporal variations of surface water quality is crucial for effective water resource management. This study aimed to identify the spatio-temporal variations of Geum River surface water quality and the factors influencing it. Results showed that summer monsoon, land-use land-cover (LULC), and weirs were the dominant factors affecting river water quality dynamics.

The declining cyanobacterial blooms in Lake Taihu (China) in 2021: The interplay of nutrients and meteorological determinants

Wu Donghao et al.

Summary: The study found that the intensity of cyanobacterial blooms in Lake Taihu decreased in 2021 due to stable wind speed, increased rainfall, and reductions in key nutrients like total nitrogen, ammonia nitrogen, and nitrate nitrogen. The results highlight the importance of nutrient reduction efforts and the need for comprehensive management measures to further improve the water quality of Lake Taihu.

Deciphering the key factors determining spatio-temporal heterogeneity of cyanobacterial bloom dynamics in the Nakdong River with consecutive large weirs

Hae-Kyung Park et al.

Summary: This study investigated harmful cyanobacterial blooms in a 200-km section of the Nakdong River in South Korea, following the construction of eight large weirs. The dominant harmful cyanobacteria found were Aphanizomenon and Microcystis spp., with a successional phenomenon observed in their blooming patterns. It was also found that upstream weirs did not affect downstream weirs in terms of harmful cyanobacterial biomass.

Long-Term Interannual and Seasonal Links between the Nutrient Regime, Sestonic Chlorophyll and Dominant Bluegreen Algae under the Varying Intensity of Monsoon Precipitation in a Drinking Water Reservoir

Ji Yoon Kim et al.

Summary: Long-term variations in the water chemistry of Daecheong Reservoir in South Korea were influenced by monsoon rainfall, with increasing chemical oxygen demand and decreasing sestonic chlorophyll-a levels observed. Total phosphorus levels decreased steadily from the riverine zone to the lacustrine area, while total coliform bacteria levels were higher at certain sites. The presence of blue-green algae species indicated eutrophic conditions, while strong correlations were found between water temperature and chlorophyll-a, and between total suspended solids and total phosphorus. Overall water quality was rated as 'good' based on a multi-metric water pollution index.

Challenges of managing harmful algal blooms in US drinking water systems

Galen Treuer et al.

Summary: The study found that previous experience with harmful algal blooms affects water managers' planning and preparation for water systems, with managers who have dealt with toxic harmful algal blooms rating them as more difficult to manage. Furthermore, managers in systems affected by toxic harmful algal blooms tend to rely more on internal resources rather than reaching out for external sources of information and technology. This trend towards self-reliance could make the effective dissemination of state-of-the-art information and solutions more difficult among water systems.

Evaluation of indicators for cyanobacterial risk in 108 temperate lakes using 23 years of environmental monitoring data

J. Li et al.

Summary: Nutrients are the main drivers for higher cyanobacterial occurrence in the 9 lakes. Thorough investigation of TP concentrations is suggested to provide important knowledge for setting nutrient targets to sustain safe drinking water supply and recreational services. The complexity of indicating cyanobacterial risk in a local condition was highlighted in this study, and future research on classifying different types of lakes and identifying their drivers is recommended.
