Influence of trace metal additions on the longevity of algal blooms across a productivity gradient

Journal of Phycology, Volume 61, Issue 6, Page 1601-1614, December 2025.
Abstract Phytoplankton require specific nutrients in varying quantities for growth, defense, and proper cell functioning. When macronutrients are present in excess, trace metals can exhibit co‐limitation on phytoplankton. This experiment aimed to understand how ambient nutrient concentrations impact phytoplankton community persistence (i.e., bloom ...

A hitchhiker's guide to modern, practical cyanobacterial taxonomy

Journal of Phycology, Volume 61, Issue 6, Page 1536-1552, December 2025.
Abstract There has been an explosion of new Cyanobacterial taxa described within the last two decades. Cyanobacteria exhibit incredible ecological versatility and morphological variability, and thousands of species have already been described using “traditional” approaches (e.g., morphological features).

Recreational Exposure to Low Concentrations of Microcystins During an Algal Bloom in a Small Lake

Marine Drugs, 2008
We measured microcystins in blood from people at risk for swallowing water or inhaling spray while swimming, water skiing, jet skiing, or boating during an algal bloom.

Biochemical indices are modulated in fish exposed to cyanobacterial toxins (microcystins)

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
In this work were summarized changes of biochemical markers of fish under the thumb of cyanobacterial toxins (microcystins). Among the most studied biomarkers of the influence of cyanobacterial toxins on fish belong oxidative stress parameters ...

Relationships among cyanobacteria, zooplankton and fish in sub-bloom conditions in the Sulejow Reservoir

Journal of Limnology, 2017
The occurrence of cyanobacteria is particularly characteristic of shallow eutrophic waters, and they often form massive ‘blooms’ that can affect aquatic invertebrates and fish.

High Levels of Structural Diversity Observed in Microcystins from Microcystis CAWBG11 and Characterization of Six New Microcystin Congeners

Marine Drugs, 2014
Microcystins (MCs) are cyclic peptides produced by cyanobacteria, which can be harmful to humans and animals when ingested. Differences in the coding of the non‑ribosomal peptide synthetase/polyketide synthase enzyme complex responsible for microcystin ...

Spatiotemporal Dynamics of Microcystin Variants and Relationships with Environmental Parameters in Lake Taihu, China

Toxins, 2015
Excessive anthropogenically-caused nutrient loading from both external and internal sources has promoted the growth of cyanobacteria in Lake Taihu from 2005 to 2014, suggesting increased production and release of cyanotoxins.
