Structure and Effects of Cyanobacterial Lipopolysaccharides

open access: yesMarine Drugs, 2015
Lipopolysaccharide (LPS) is a component of the outer membrane of mainly Gram-negative bacteria and cyanobacteria. The LPS molecules from marine and terrestrial bacteria show structural variations, even among strains within the same species living in the

Subchronic Toxicity of Microcystin-LR on Young Frogs (Xenopus laevis) and Their Gut Microbiota

open access: yesFrontiers in Microbiology, 2022
Although toxic effects of microcystins (MCs) in mammals and fish have been extensively studied, the effects of MCs on the immune system and gut microbiota of amphibians have not received sufficient attention. As MCs cause general damage to the vertebrate

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

open access: yesJournal of Fish Diseases, EarlyView.
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.

Maximization of cyanobacterial growth and cyanotoxin productivity [PDF]

open access: yes, 2015
Cyanobacteria group comprises more than 2000 species of prokaryotic organisms and they are commonly named "blue-green algae", in spite of being nowadays classified as Gramnegative bacteria.

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

open access: yesEnvironmental 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 ...

Research Priorities for Robust Climate Assessments in the United States

open access: yesEarth'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 ...

Investigating Cyanotoxin Production by Benthic Freshwater Cyanobacteria in New Zealand [PDF]

open access: yes, 2012
Cyanobacteria can form nuisance proliferations and produce large concentrations of toxins that pose a health hazard. This thesis investigates cyanotoxin production by New Zealand benthic cyanobacteria.

Exploring cyanotoxin diversity in field samples – an untargeted HRMS/MS based approach

open access: yes, 2022
Robust cyanotoxin analysis is challenging because of the existence of multiple cyanotoxin classes with differing chemical properties, a large number of structural analogues, the scarcity of chemical standards and the complex matrices in which cyanotoxins

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 ...
