From colonial clusters to colonial sheaths: Imaging flow cytometry analysis of Microcystis morphospecies dynamics in mesocosm and links to CyanoHABs management

open access: yesEcological Indicators
The alarming increase in the frequency of blooms of Microcystis in freshwater lakes and reservoirs occurs worldwide, with major implications for their ecosystem functioning and water quality.

Microcystins in components of twelve New Hampshire lakes of varied trophic status [PDF]

open access: yes, 1999
Cyanobacteria toxins, called microcystins (MCs), were found in components of twelve, stratified New Hampshire (USA) lakes of varied trophic status during the summer of 1998.

Do Cyanobacteria Blooms Enhance Parasite Loads in Lake Erie Yellow Perch? [PDF]

open access: yes, 2020
Harmful Algal Blooms composed of cyanobacteria (HABs) are a major concern globally, especially in ecosystems that support commercial and recreational fisheries. Although HABs have been shown to negatively affect the services provided by ecosystems (e.g.,

The Effect of Temperature on Recovery of Buoyancy by Microcystis [PDF]

open access: yesMicrobiology, 1986
Summary: Colonies of Microcystis in Abbots Pool, Avon, UK, were found to regulate their buoyancy according to light (photon flux density). The autumnal decline of the population was associated with an increase in the proportion of colonies that were non-buoyant, and with declining temperatures in the pond.

A comprehensive review on the sources, environmental behavior, and degradation of alkylphenol ethoxylates and their metabolites in surface water and soils

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Alkylphenol ethoxylates (APEOs) and their metabolites, widely used in agricultural, industrial, and household products, are known endocrine disruptors. Since the 1980s, many countries have implemented restrictions on their production and use, necessitating an evaluation of these regulations by reviewing their source and environmental behavior ...

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

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

SAMSON: Spectral Absorption-fluorescence Microscopy System for ON-site-imaging of algae [PDF]

open access: yes, 2018
This paper presents SAMSON, a Spectral Absorption-fluorescence Microscopy System for ON-site-imaging of algae within a water sample. Designed to be portable and low-cost for on-site use, the optical sub-system of SAMSON consists of a mixture of low-cost ...

Nutrient inversion but not warming drive changes in periphyton biomass and composition in shallow lake mesocosms

open access: yesLimnology and Oceanography, EarlyView.
Abstract Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can contribute to the development of more efficient techniques for the restoration of lakes in a

Occurrence and Distribution of Cyanobacteria and their Toxins in Silver Lake, New Hampshire [PDF]

open access: yes, 2008
A study of Silver Lake, NH was performed as part of a 5-lake assessment of cyanobacteria prevalence and distribution. Multi-parameter fluorescence probe measurements of chlorophyll a and cyanobacteria concentrations (PC, phycocyanin fluorescence) were ...

Integrating phytoplankton phenology, traits, and model‐data fusion to advance bloom prediction

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract While there is a diversity of approaches for modeling phytoplankton blooms, their accuracy in predicting the onset and manifestation of a bloom is still lagging behind what is needed to support effective management. We outline a framework that integrates trait theory and ecosystem modeling to improve bloom prediction.
