The Individual and Combined Effects of the Cyanotoxins, Anatoxin-a and Microcystin-LR, on the Growth, Toxin Production, and Nitrogen Fixation of Prokaryotic and Eukaryotic Algae

Toxins, 2019
Globally, eutrophication and warming of aquatic ecosystems has increased the frequency and intensity of cyanobacterial blooms and their associated toxins, with the simultaneous detection of multiple cyanotoxins often occurring.

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Phytoplankton Communities and Cyanotoxin Production in Some Bulgarian Lowland Lakes and Reservoirs

Studia Ecologiae et Bioethicae, 2022
One of the most evident consequences of eutrophication of waters is the progressive spreading of persistent cyanobacterial blooms. They are often accompanied by the production of cyanotoxins in concentrations, which are hazardous for human health.

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, Volume 41, Issue 10, Page 807-821, October 2026.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

Four Decades of Reach‐Scale Declines in Total Phosphorus Across the Yellow River Basin Driven by Vegetation Restoration and Dam Impoundment

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Phosphorus (P) is a finite resource fundamental to terrestrial and aquatic productivity. However, excessive P transfer from land to rivers threatens food production and degrades water quality. Systematic analyses of multidecadal total phosphorus (TP) variation in large river basins remain challenging because of incomplete and non‐uniform ...

Plant-cyanobacteria Interaction: Phytotoxicity of Cyanotoxins [PDF]

, 2010
Cyanobacteria from freshwater and also from marine sources produce a wide array of toxic chemicals and secondary or bioactive metabolites. These are mainly nitrogen-rich alkaloids and peptides and are now identified as to pose threats both to human and ...

Cyanotoxins in Lake Garda? The critical evaluation of chemodiversity [PDF]

, 2013
Anthropic pressure and climate changes are the major stressors in lakes. Both factors play an important role in the development of cyanobacteria with the capability of producing toxic metabolites (cyanotoxins).

The occurrence and human health risk assessment of microcystins in diverse food matrixes during production

Heliyon
Globally, the presence of cyanotoxins in water supplies and food has been widely investigated for over a decade. Cyanotoxins are harmful metabolites produced by toxic cyanobacterial genera.

Research Priorities for Robust Climate Assessments in the United States

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Scientific assessments play a critical role in synthesizing evidence to support evidence‐based decision‐making in many sectors and topics. For climate change, large‐scale assessments like the Intergovernmental Panel on Climate Change (IPCC) and the United States (U.S.) National Climate Assessment (NCA) reports help many different users—from ...
