First report of a toxic nodularia spumigena (Nostocales/Cyanobacteria) bloom in sub-tropical Australia. II. bioaccumulation of nodularin in isolated populations of mullet (Mugilidae) [PDF]

, 2012
Fish collected after a mass mortality at an artificial lake in south-east Queensland, Australia, were examined for the presence of nodularin as the lake had earlier been affected by a Nodularia bloom.

Rekombination hybrider Megasynthasen als Schlüssel für die Evolution metabolischer Diversität in Cyanobakterien

Angewandte Chemie, Volume 137, Issue 26, June 24, 2025.
Natürliche Kombinatorik: Die evolutionäre Rekombination und Anpassung von drei cyanobakteriellen Biosynthese‐Genclustern führte zur Entstehung von Minutumamiden, einer neuen Familie von Peptid‐Polyketid‐Hybriden. Mittels retro‐evolutionärer Analyse gelang die Entdeckung des Nostopeptolids KVJ3, einem evolutionären Vorfahren, der die Biosynthese von ...

Mixing and Matching of Hybrid Megasynthases is a Hub for the Evolution of Metabolic Diversity in Cyanobacteria

Angewandte Chemie International Edition, Volume 64, Issue 26, June 24, 2025.
Natural combinatorics: Evolutionary mixing and matching of three cyanobacterial biosynthetic gene clusters resulted in the emergence of minutumamides, a novel family of peptide‐polyketide hybrids. Retro‐evolutionary analysis led to the discovery of nostopeptolide KVJ3, an evolutionary ancestor that links nostopeptolide and minutumamide biosynthesis and

The Great Lakes Winter Grab: Limnological data from a multi‐institutional winter sampling campaign on the Laurentian Great Lakes

Limnology and Oceanography Letters, Volume 10, Issue 1, Page 37-61, February 2025.
Abstract Interest in winter limnology is growing rapidly, but progress is hindered by a shortage of standardized multivariate datasets on winter conditions. Addressing the winter data gap will enhance our understanding of winter ecosystem function and of lake response to environmental change.

In vivo assessment of nodularin-induced hepatotoxicity in the rat using magnetic resonance techniques (MRI, MRS and EPR oximetry)

, 2002
Acute nodularin-induced hepatotoxicity was assessed in vivo, in rats using magnetic resonance (MR) techniques, including MR imaging (MRI), MR spectroscopy (MRS), and electron paramagnetic resonance (EPR) oximetry.

Mechanisms of Pesticide Toxicity in Fish: Insights Into the Ameliorative Role of Plant‐Derived Compounds—A Review

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
Pesticide contamination in aquatic environments poses severe risks to fish health, causing oxidative stress, immunosuppression, endocrine disruption, and neurotoxicity. These effects result from the accumulation of reactive oxygen species (ROSs), enzyme inhibition, and damage to physiological systems. Plant‐derived compounds and phytochemicals, such as

Accumulation of nodularin in New Zealand shortfin eel (Anguilla australis): potential consequences for human consumption

, 2017
The native Anguilla australis (shortfin eel) is a culturally significant species for indigenous Māori populations of New Zealand. At Lake Forsyth/Te Wairewa (Canterbury), local Māori have depended on A.

Effects of Seasonal Dynamics on Cyanobacteria Proliferation in Aquaculture Fish Ponds

Aquaculture Research, Volume 2025, Issue 1, 2025.
Aquaculture production supports the United Nations Sustainable Development Goals (SDGs), especially SDG 2 (Zero Hunger), by enhancing food security and sustainable practices. This study investigated the seasonal dynamics of cyanobacterial (CB) blooms in aquaculture fishponds in South Africa (SA) and Nigeria (NGA). Water samples were collected twice per

Selective left-lobe atrophy by nodularin treatment accompanied by reduced protein phosphatase 1/2A and increased peroxisome proliferation in rat liver.

, 2001
The effect of nodularin on selective atrophy of left lobes in the liver was investigated in F344 rats. Nodularin was injected for 10 weeks from the third week of initiation with saline or N-nitrosodiethylamine (DEN), grouped as S/N and D/N, respectively.

Macro‐ and micronutrient effects on phytoplankton in Green Bay, Lake Michigan, and the western basin of Lake Erie

Journal of Phycology, Volume 60, Issue 6, Page 1514-1527, December 2024.
Abstract Efforts to reduce the frequency, extent, and toxicity of harmful algal blooms (HABs) require knowledge about drivers of algal growth, toxin production, and shifts in phytoplankton community composition to cyanobacterial dominance. Although labile nitrogen (N) and phosphorus (P) fuel primary production, micronutrients also play roles as the ...
