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

open access: yesBiological 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 ...

Semi-automated classification of colonial Microcystis by FlowCAM imaging flow cytometry in mesocosm experiment reveals high heterogeneity during seasonal bloom

open access: yesScientific Reports, 2021
A machine learning approach was employed to detect and quantify Microcystis colonial morphospecies using FlowCAM-based imaging flow cytometry. The system was trained and tested using samples from a long-term mesocosm experiment (LMWE, Central Jutland ...

A Review of the Effects of Freshwater Habitat Quality on Aquatic & Semi‐Aquatic Turtles

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This literature review aims to provide a comprehensive review of the relationship between freshwater turtles and their aquatic environments. We also highlight areas which have been over‐ or under‐studied and offer recommendations for future research. ABSTRACT Freshwater turtles and terrapins require an aquatic habitat as part of their natural ecology ...

Metagenomic analysis reveals symbiotic relationship among bacteria in Microcystis-dominated community

open access: yesFrontiers in Microbiology, 2016
Microcystis bloom, a cyanobacterial mass occurrence often found in eutrophicated water bodies, is one of the most serious threats to freshwater ecosystems worldwide. In nature, Microcystis forms aggregates or colonies that contain heterotrophic bacteria.

Nutrient enrichment destabilizes aquatic food webs through synchronization within and across trophic levels

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2475-2489, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient enrichment destabilizes ecosystems globally, but the mechanistic pathways underlying this effect in multi‐trophic communities remain unclear. To address this knowledge gap, we applied biodiversity–stability theory to multi‐trophic communities by partitioning ...

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

open access: yesLimnology 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

open access: yesJournal 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

open access: yesGeophysical 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 ...

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Growth Inhibition of Microcystis Cyanobacteria by L-Lysine and Disappearance of Natural Microcystis Blooms with Spraying

open access: yesMicrobes and Environments, 2004
Low concentrations of L-lysine and L-lysine-containing-peptides strongly inhibited the growth of axenic strains of 4 species belonging to the genus Microcystis (cyanobacteria). Inhibitory activities decreased in the order of L-lysine>tri-L-lysine>di-L-lysine>α-poly-L-lysine>L-lysyl-L-histidine>L-lysyl-L-alanine.
