Dense surface blooms of toxic cyanobacteria in eutrophic lakes may lead to mass mortalities of fish and birds, and provide a serious health threat for cattle, pets, and humans. It has been argued that global warming may increase the incidence of harmful algal blooms. Here, we report on a lake experiment where intermittent artificial mixing failed to control blooms of the harmful cyanobacterium Microcystis during the summer of 2003, one of the hottest summers ever recorded in Europe.

Importance of climate change-physical forcing on the increase of cyanobacterial blooms in a small, stratified lake
The community structure of planktonic cyanobacteria was studied in a dimictic lake in which recurrent summer surface algal blooms have frequently occurred since the beginning of this millennium. In
Rising CO2 Levels Will Intensify Phytoplankton Blooms in Eutrophic and Hypertrophic Lakes
A mathematical model is developed to predict dynamic changes in dissolved inorganic carbon (DIC), pH and alkalinity during phytoplankton bloom development and warns that rising CO2 levels may result in a marked intensification of phy Topolankton blooms in eutrophic and hypertrophic waters.
Harmful filamentous cyanobacteria favoured by reduced water turnover with lake warming
Evidence is presented that climate change-induced lake warming may cause the same undesired effects as have formerly emerged from excess nutrients (eutrophication) as well as unidirectional lake-restoration measures in parallel with recurrent absence of holomixis owing to lake warming.
How rising CO2 and global warming may stimulate harmful cyanobacterial blooms.
Continental scale cyanobacterial dynamics under global warming and eutrophication
On-going global warming and eutrophication are expected to promote cyanobacterial dominance worldwide. Although increased lake temperature and nutrients are well-established drivers of blooms, the
Warmer climates boost cyanobacterial dominance in shallow lakes
Dominance by cyanobacteria hampers human use of lakes and reservoirs worldwide. Previous studies indicate that excessive nutrient loading and warmer conditions promote dominance by cyanobacteria, but
Response of Natural Cyanobacteria and Algae Assemblages to a Nutrient Pulse and Elevated Temperature
The results of this study confirm that warming alone yields marginally higher cyanobacterial chlorophyll-a concentrations, yet that a pulse of additional nutrients is boosting blooms, which indicates that nutrient control strategies –catchment as well as in-system measures– could increase the resilience of surface waters to the negative effects of climate change.
Harmful cyanobacteria: Favored by global warming but suppressed by rising CO2?
Introduction Cyanobacteria are the Earth’s oldest known oxygen-producing organisms, with fossil remains dating back ~3.5 billion years. Their proliferation during the Precambrian period is largely
Cyanobacteria dominance: Quantifying the effects of climate change
An increase in cyanobacteria bloom formation within lakes has been forecasted as a result of global warming. We investigated the particular physical and chemical thresholds for cyanobacteria


Summer flow event induces a cyanobacterial bloom in a seasonal Western Australian estuary
The model simulations show that the hydrological conditions, in combination with high concentrations of inorganic nutrients, promoted rapid phytoplankton growth, favouring dominance by M. aeruginosa in the Swan River estuary.
Turbulent mixing and phytoplankton spring bloom development in a deep lake
A one‐dimensional (1‐D) mechanistic phytoplankton model combined with a 1‐D hydrodynamic model was applied to simulate phytoplankton growth during winter and spring in deep monomictic Upper Lake
The Microcystis cyanobacteria bloom in the Swan River--February 2000.
The Swan-Canning estuary in Western Australia experienced a record bloom of the toxic cyanobacteria Microcystis aeruginosa in February 2000, when the freshwater flush subsided and seawater intrusion from the Indian Ocean re-established itself, raising the salinities above the tolerance of MicroCystis.
Testing the Sensitivity of Phytoplankton Communities to Changes in Water Temperature and Nutrient Load, in a Temperate Lake
Freshwater lakes are biologically sensitive to changes in the surrounding environment and the impacts that such changes have on their water quality are of considerable ecological, recreational and
Water management strategies against toxic Microcystis blooms in the Dutch delta.
This study aims at an advance assessment of two management strategies to suppress toxic Microcystis blooms in the former Volkerak estuary through the development of a mechanistic model of the population dynamics of MicrocyStis.
Artificial mixing prevents nuisance blooms of the cyanobacterium Microcystis in Lake Nieuwe Meer, the Netherlands
1. Artificial mixing in the hypertrophic Lake Nieuwe Meer was successful in preventing blooms of the cyanobacterium Microcystis. During the 2 years of artificial, deep mixing the number of colonies
Climate-induced shifts in an experimental phytoplankton community: a mechanistic approach
Experimental and model results indicate that the different algal functional groups respond differently to climate warming under phosphorus-limited conditions, and cyanobacteria showed a stronger response to the different climate warming scenarios than diatoms or green algae.
Changes in turbulent mixing shift competition for light between phytoplankton species
Competition theory is developed that predicts how changes in turbulent mixing affect competition for light between buoyant and sinking phytoplankton species, and warns that changes in the turbulence structure of natural waters, for instance driven by climate change, may induce major shifts in the species composition of phytopsized communities.
Earlier onset of the spring phytoplankton bloom in lakes of the temperate zone in a warmer climate
The decoupling of trophic interactions is potentially one of the most severe consequences of climate warming. In lakes and oceans the timing of phytoplankton blooms affects competition within the
Effects of experimentally induced cyanobacterial blooms on crustacean zooplankton communities
It is demonstrated that zooplankton communities can be negatively affected by cyanobacterial blooms and therefore the potential to use herbivory to reduce algal blooms in such eutrophic lakes appears limited.
