Earlier spring may explain dominance of the slow‐growing dinoflagellate Naiadinium polonicum over the cyanobacterium Microcystis during a heatwave

Journal of Phycology, EarlyView.
Abstract Global warming and extreme weather events have been linked to a rise in cyanobacterial blooms, which threaten water quality and ecosystem services. However, during an extreme hot and dry summer, Microcystis was outcompeted by a dinoflagellate, Naiadinium polonicum, in a drinking water lake in southern Sweden.

Cyanobacterial Bloom Formation by Enhanced Ecological Adaptability and Competitive Advantage of Microcystis—Non-Negligible Role of Quorum Sensing

Microorganisms
Microcystis-dominated cyanobacterial blooms (MCBs) frequently occur in freshwaters worldwide due to massive Microcystis colony formation and severely threaten human and ecosystem health.

The allelopathic algicides sanguinarine and berberine reduced the dominance of Microcystis in competition with Chlorella

Results in Engineering, 2022
Gramine, sanguinarine and berberine are potential algicides that can significantly inhibit the growth of cyanobacteria. Their effects on other phytoplankton have to be considered, because other phytoplankton species and cyanobacteria usually co-exist. In

Circumscription of three new taxa of Merismopedia‐like Cyanobacteria shows how far convergent evolution can go

Journal of Phycology, EarlyView.
Abstract The genus Merismopedia (Merismopediaceae, Chroococcales), characterized by rectangular colonies with cells arranged in regular perpendicular rows and columns, represents a challenging study system due to its limited cultivability. The genus recently underwent taxonomic revision using cultivation‐independent techniques and a polyphasic approach.

Comparative studies on physiological responses to phosphorus in two phenotypes of bloom-forming Microcystis [PDF]

, 2007
Toxic Microcystis blooms frequently occur in eutrophic water bodies and exist in the form of colonial and unicellular cells. In order to understand the mechanism of Microcystis dominance in freshwater bodies, the physiological and biochemical responses ...

Climate Change and Temperature‐Based Stratification in Shallow Lakes and Ponds in Warm Climate Regions

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Thermal stratification in shallow lakes (< 5 m, > 5 ha) and ponds (< 5 m, < 5 ha) in warm climate regions is understudied. A comprehensive review was done to identify the effects of climate change on stratification patterns, their effects on the ecology of shallow waterbodies and implications for management of shallow waterbodies.

Flexibility of Microcystis Overwintering Strategy in Response to Winter Temperatures

Microorganisms, 2021
Microcystis is one of the most common bloom-forming cyanobacteria in freshwater ecosystems throughout the world. However, the underlying life history mechanism and distinct temporal dynamics (inter- and intra-annual) of Microcystis populations in ...

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, Volume 41, Issue 11, Page 1299-1310, November 2026.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Taxonomic notes on water bloom forming Microcystis species (Cyanophyta) from China - An example from samples of the Dianchi Lake

, 2007
Ten common species of Microcystis, based on the examination of water samples from the Dianchi Lake, Yunnan, China, were morphologically described, and their taxonomy was also discussed.

Characterisation of host growth after infection with a broad-range freshwater cyanopodophage [PDF]

, 2014
Freshwater cyanophages are poorly characterised in comparison to their marine counterparts, however, the level of genetic diversity that exists in freshwater cyanophage communities is likely to exceed that found in marine environments, due to the habitat
