Contribution of bioturbation by the red swamp crayfish Procambarus clarkii to the recruitment of bloom-forming cyanobacteria from sediment

Journal of Limnology, 2010
The development of cyanobacterial blooms in a small eutrophic pond was monitored along with the potential effect of bioturbation by the red swamp crayfish Procambarus clarkii discussed as well with respect to the recruitment of cyanobacteria from ...

Road salt pollution shifts urban stormwater ponds toward cyanobacterial dominance

Limnology and Oceanography Letters, EarlyView.
Abstract Urban environments contend with an array of stressors, including salinization by deicing road salts. To advance understanding of how road salt pollution affects aquatic ecosystem functioning, we surveyed primary producers in 50 stormwater ponds in Brampton, Canada.

Spatiotemporal dynamics of microbial communities and cyanobacteria blooms in two North American Lakes using long-read 16S rRNA sequencing

Ecological Indicators
Understanding spatial and temporal heterogeneity in ecosystems is essential to forecasting the effects of environmental changes. Freshwater microbes, including cyanobacteria, play a crucial role in food-web structures and biochemical processes, yet can ...

Physicochemical Process, Crustacean, and Microcystis Biomass Changes In Situ Enclosure after Introduction of Silver Carp at Meiliang Bay, Lake Taihu

Scientifica, 2017
In order to control cyanobacteria blooms with silver carp in Lake Taihu, an in situ experiment was carried out by stocking silver carp at a biomass of 35, 70, and 150 g m-3 and no carp control in waterproof enclosures.

The Microcystis cyanobacteria bloom in the Swan River - February 2000

Water Science and Technology, 2001
In February 2000 the Swan-Canning estuary in Western Australia experienced a record bloom of the toxic cyanobacteria Microcystis aeruginosa. At its height, concentrations of M. aeruginosa reached integrated water column cell counts of 15,000/ml and formed bright green scums in sheltered bays, where counts of 130 million cells/ml were recorded.

A novel artificial intelligence–powered cell counting tool coupled with digital microscopy for rapid field‐assessment of harmful cyanobacterial blooms

Limnology and Oceanography: Methods, EarlyView.
ABSTRACT Historical quantification of cyanobacterial harmful algal blooms (cHABs) typically involved labor‐intensive manual cell counting. We developed a novel, cost‐effective, field‐validated system to perform cell counts of six common toxin‐producing cyanobacterial genera within 30 s of upload with 10‐min sample preparation.

Spatial and Temporal Patterns in the Seasonal Distribution of Toxic Cyanobacteria in Western Lake Erie from 2002–2014

Toxins, 2015
Lake Erie, the world’s tenth largest freshwater lake by area, has had recurring blooms of toxic cyanobacteria for the past two decades. These blooms pose potential health risks for recreation, and impact the treatment of drinking water. Understanding the

Using environmental DNA to detect Microseira wollei (Oscillatoriales), a benthic harmful algal bloom, in Lake St. Clair (Michigan, USA)

Limnology and Oceanography: Methods, EarlyView.
Abstract Microseira wollei is a benthic cyanobacterium that can cause harmful algal blooms (HABs) and often requires management. However, a pervasive challenge for M. wollei management is characterizing the spatial and temporal extent of an impacted area, which can be time and resource intensive.
