Nutrient pulse scenarios drive contrasting patterns in the functional stability of freshwater phytoplankton

Limnology and Oceanography, EarlyView.
Abstract Climate change is increasing the frequency, intensity, and stochasticity of extreme weather events such as heavy rainfall, storm‐induced mixing, or prolonged drought periods. This results in more variable regimes of dissolved nutrients and carbon in lakes and induces temporal fluctuations in the resource availability for plankton communities ...

Characteristics of Wetting-Induced Bacteriophage Blooms in Biological Soil Crust. [PDF]

, 2019
Biological soil crusts (biocrusts) are photosynthetic "hot spots" in deserts and cover ∼12% of the Earth's terrestrial surface, and yet they face an uncertain future given expected shifts in rainfall events.

Picophytoplankton act as the primary consumers of excess phosphorus after the spring bloom in the eutrophic Baltic Sea

Limnology and Oceanography, EarlyView.
Abstract Eutrophication in the Baltic Sea has caused an imbalance in the inorganic nitrogen (N) to phosphorus (P) ratio, leaving excess phosphate (PO4) after the phytoplankton spring bloom that terminates after N depletion. Using monitoring data, we demonstrated that the PO4 concentration has continued to increase in the outermost Gulf of Finland ...

Early Detection Methods for Toxic Cyanobacteria Blooms

Pathogens
Harmful cyanobacterial blooms produce cyanotoxins which can adversely affect humans and animals. Without proper monitoring and detection programs, tragedies such as the loss of pets or worse are possible. Multiple factors including rising temperatures and human influence contribute to the increased likelihood of harmful cyanobacteria blooms.

Phytoplankton Community and Algal Toxicity at a Recurring Bloom in Sullivan Bay, Kabetogama Lake, Minnesota, USA [PDF]

, 2019
Kabetogama Lake in Voyageurs National Park, Minnesota, USA suffers from recurring late summer algal blooms that often contain toxin-producing cyanobacteria.

Blooms of filamentous cyanobacteria reduce zooplankton quality and pelagic food web efficiency

Limnology and Oceanography, EarlyView.
Abstract Cyanobacterial blooms in marine and freshwater ecosystems have increased in magnitude, frequency, and distribution worldwide during recent decades. Filamentous cyanobacteria are of unsuitable size for mesozooplankton feeding and of poorer nutritional quality than other phytoplankton taxa. The production and quality of higher trophic levels are

Co-Occurrence of Toxic Bloom-Forming Cyanobacteria Planktothrix, Cyanophage, and Symbiotic Bacteria in Ohio Water Treatment Waste: Implications for Harmful Algal Bloom Management

Toxins
Cyanobacterial blooms are increasingly becoming more intense and frequent, posing a public health threat globally. Drinking water treatment plants that rely on algal bloom-affected waters may create waste (water treatment residuals, WTRs) that ...

Genomic signatures of Lake Erie bacteria suggest interaction in the Microcystis phycosphere.

PLoS ONE, 2021
Microbial interactions in harmful algal bloom (HAB) communities have been examined in marine systems, but are poorly studied in fresh waters. To investigate HAB-microbe interactions, we isolated bacteria with close associations to bloom-forming ...

Evaluating Ultrasonicator Performance for Cyanobacteria Management at Freshwater Sources

Toxins, 2023
Algal blooms consisting of potentially toxic cyanobacteria are a growing source water management challenge faced by water utilities globally. Commercially available sonication devices are designed to mitigate this challenge by targeting cyanobacteria ...

Toxic cyanobacteria blooms in the Lithuanian part of the Curonian Lagoon [PDF]

OCEANOLOGIA, 2009
The phenomenon of cyanobacteria (blue-green algae) blooms in the Baltic and the surrounding freshwater bodies has been known for several decades. The presence of cyanobacterial toxic metabolites in the Curonian Lagoon has been investigated and demonstrated for the first time in this work (2006-2007).
