In situ studies on physiological and biochemical responses of four fishes with different trophic levels to toxic cyanobacterial blooms in a large Chinese lake [PDF]

open access: yes, 2007
Physiological and biochemical responses of four fishes with different trophic levels to toxic cyanobacterial blooms were studied in a large net cage in Meiliang Bay, a hypereutrophic region of Lake Taihu.

Advancing Knowledge on Cyanobacterial Blooms in Freshwaters [PDF]

open access: yesWater, 2020
Cyanobacterial blooms have become a frequent phenomenon in freshwaters worldwide; they are a widely known indicator of eutrophication and water quality deterioration. Information and knowledge contributing towards the evaluation of the ecological status of freshwaters, particularly since many are used for recreation, drinking water, and aquaculture, is

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

open access: yesEcological Indicators, 2022
The cyanobacterial blooms are global environmental perils and have been extensively compounded and changeable in Lake Taihu with emerging significantly higher intensities during 2016–2019 than those in 2010–2015.

Occurrence and toxicity of Microcystis aeruginosa (Cyanobacteria) in the Paraná River, downstream of the Yacyretá dam (Argentina) [PDF]

open access: yes, 2016
Cyanobacteria constitute the main toxin producers in inland water ecosystems and have extensive global distribution. The presence of hepatotoxins in aquatic environments is hazardous to human and animal health; even though the presence and identification

Cyanobacterial blooms in Lake Atitlan, Guatemala

open access: yesLimnologica, 2011
AbstractLake Atitlan, one of the most important lakes not only in Central America but in the whole world, is facing serious problems with increasing water pollution. Over the last several decades, the uncontrolled nutrient input into the lake has lead to high P levels and low N:P ratios, initiating cyanobacterial blooms.

Viruses may facilitate the cyanobacterial blooming during summer bloom succession in Xiangxi Bay of Three Gorges Reservoir, China

open access: yesFrontiers in Microbiology, 2023
The occurrence of cyanobacterial blooms in summer are frequently accompanied by the succession of phytoplankton communities in freshwater. However, little is known regarding the roles of viruses in the succession, such as in huge reservoirs.

Impact of cyanobacterial bloom on microbiomes of freshwater lakes

open access: yesJournal of Biosciences, 2021
Cyanobacterial blooms are harmful because of their cyanotoxins production. It occurs due to the eutrophication of freshwater reserves. Nagpur city has three lakes which serves as public water resource and are affected by algal bloom events. Metagenomic approach was used for the exploration of taxonomic, catabolic, and resistome profile of these lakes ...

Characteristics and roles of Microcystis extracellular polymeric substances (EPS) in cyanobacterial blooms: a short review

open access: yesJournal of Freshwater Ecology, 2018
Cyanobacterial blooms are serious eco-environmental problem, and cyanobacteria can produce large amounts of extracellular polymeric substances (EPS). EPS, as complex polymers, possess several characteristics, such as hydrophobicity, carbon-rich, nutrient-

Increasing Microcystis cell density enhances microcystin synthesis: a mesocosm study [PDF]

open access: yes, 2012
An experimental protocol using mesocosms was established to study the effect of Microcystis sp. cell abundance on microcystin production. The mesocosms (55 L) were set up in a shallow eutrophic lake and received either no (control), low (to simulate a ...

Interannual Variability of Cyanobacterial Blooms in Lake Erie

open access: yesPLoS ONE, 2012
After a 20-year absence, severe cyanobacterial blooms have returned to Lake Erie in the last decade, in spite of negligible change in the annual load of total phosphorus (TP). Medium-spectral Resolution Imaging Spectrometer (MERIS) imagery was used to quantify intensity of the cyanobacterial bloom for each year from 2002 to 2011.
