Responses of Gut Microbial Community Composition and Function of the Freshwater Gastropod Bellamya aeruginosa to Cyanobacterial Bloom

Frontiers in Microbiology, 2022
Freshwater gastropods are widely distributed and play an important role in aquatic ecosystems. Symbiotic microorganisms represented by gut microbes can affect the physiological and biochemical activities of their hosts.

Nutrient disturbance in a shallow aquaculture pond impacts Microcystis gene expression but does not impact bacterial community function during bloom conditions

Journal of Phycology, EarlyView.
Abstract Cyanobacterial harmful algal blooms (cHABs) are worldwide issues. Reduced nitrogen forms (ammonium and urea) have recently been measured in freshwater systems at concentrations not previously recorded. These reduced nitrogen forms have been shown to favor the proliferation of harmful cyanobacteria.

Variations in the Microcystin Content of Different Fish Species Collected from a Eutrophic Lake

Toxins, 2013
Microcystins produced from cyanobacteria can accumulate in fish tissues. Liquid chromatography coupled with tandem quadrupole mass spectrometry (LC-MS/MS) is an attractive alternative to immunoassays for the determination of low concentrations of ...

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

Biological Reviews, Volume 101, Issue 4, Page 1904-1921, August 2026.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

Satellite Remote Sensing of Drinking Water Intakes in Lake Erie for Cyanobacteria Population Using Two MODIS-Based Indicators as a Potential Tool for Toxin Tracking

Frontiers in Marine Science, 2017
The growth of toxic Cyanobacterium, Microcystis aeruginosa, and the production of toxins, microcystins, pose serious concerns for the ecological health of lakes, such as western Lake Erie.

PHLPP is neither a Phosphatase nor a Tumor Suppressor

BioEssays, Volume 48, Issue 7, July 2026.
PH domain leucine‐rich repeat protein phosphatases (PHLPP) have been described as Akt phosphatases and tumor suppressors for more than 20 years. Recent evidence, however, indicates that they are pseudophosphatases that lost catalytic activity more than 450 Mya. This article argues that new hypotheses are urgently needed to reorient the field.

Shifting ice phenology and ice extent linked to harmful algal bloom severity

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Ice cover on lakes can have far‐reaching and profound effects on ecosystem structure and function. However, the duration and spatial extent of ice cover is changing rapidly with warming aquatic ecosystems. This loss of ice creates an urgent need to understand how lakes will function without ice cover, both during the ice‐on and ice‐free season,

Historical Records of Nutrient Loading Into End‐Member Mid‐Latitude Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Human‐induced environmental changes impact lakes in temperate regions, but detailed lake basin histories that pre‐date instrumental records are limited. Most paleolimnological reconstructions are used to examine single lakes in isolation, making it difficult to separate regional forcings from morphological influences on a sedimentary signal ...

Initial Assessment of the Detectability of Cyanotoxin Occurrence Using PACE Satellite Observations

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Microcystin is a major public health hazard during freshwater cyanobacterial blooms, yet its remote detection remains challenging because it lacks any direct optical absorption features. We demonstrate that hyperspectral observations from NASA's PACE Ocean Color Instrument (OCI) can be used to detect elevated microcystin concentrations by ...

A Review of Cardiovascular Toxicity of Microcystins [PDF]

Toxins, 2019
The mortality rate of cardiovascular diseases (CVD) in China is on the rise. The increasing burden of CVD in China has become a major public health problem. Cyanobacterial blooms have been recently considered a global environmental concern. Microcystins (MCs) are the secondary products of cyanobacteria metabolism and the most harmful cyanotoxin found ...
