Responses of yellow catfish (Pelteobagrus fulvidraco Richardson) exposed to dietary cyanobacteria and subsequent recovery [PDF]

, 2012
A 120-day toxicity experiment was conducted to investigate the effect of dietary cyanobacteria on the growth and liver histopathology of yellow catfish, and subsequent recovery when the fish were free of cyanobacteria.

Cyanobacteria and cyanotoxins in Polish freshwater bodies [PDF]

Oceanological and Hydrobiological Studies, 2013
Abstract In this work, the authors examined the presence of cyanobacteria and cyanotoxins in 21 samples collected from fresh water bodies located in 5 provinces in Poland: Lublin (2), Podlasie (1), Pomerania (6), Warmia-Masuria (1) and Wielkopolska (11).

Blooms of the blue-green alga Cylindrospermopsis raciborskii in Emilia Romagna region (Italy): case reports managed by the Regional Agency for Environmental Protection and Energy of Emilia Romagna (ARPAE)

Advances in Oceanography and Limnology
Cylindrospermopsis raciborskii is a toxic cyanobacterium that can form blooms potentially harmful to humans and animals. The proliferation of this species is difficult to predict, and its blooms are hard to detect as they cause just a moderate change in

The Cyanotoxin BMAA Induces Heterocyst Specific Gene Expression in Anabaena sp. PCC 7120 under Repressive Conditions

Toxins, 2018
Cyanobacteria synthesize neurotoxic β-N-methylamino-l-alanine (BMAA). The roles of this non-protein amino acid in cyanobacterial cells are insufficiently studied. During diazotrophic growth, filamentous cyanobacteria form single differentiated cells,

Examining Short Temporal Changes in Intertidal Macroalgal Microbiomes at 'Ewa Beach, O'Ahu, Hawai'i: Some Hosts Varied While Others Remained Stable

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
We examined microbiome variability in seven macroalgal species over 5 days at an intertidal bench in 'Ewa Beach, O'ahu, Hawai'i. Microbial communities of some red and brown algae fluctuated, whilst green algae remained stable. Temporal patterns varied by species and potentially by differences in intertidal positioning and exposure to environmental ...

Do Cyanobacteria Blooms Enhance Parasite Loads in Lake Erie Yellow Perch? [PDF]

, 2020
Harmful Algal Blooms composed of cyanobacteria (HABs) are a major concern globally, especially in ecosystems that support commercial and recreational fisheries. Although HABs have been shown to negatively affect the services provided by ecosystems (e.g.,

Integration of epigenetics into ecotoxicology: insights and fundamental research needs

Biological Reviews, Volume 101, Issue 2, Page 826-847, April 2026.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

Transdisciplinary approaches for the study of cyanobacteria and cyanotoxins. [PDF]

Curr Res Microb Sci
Cyanobacteria, ancient aerobic and photoautotrophic prokaryotes, thrive in diverse ecosystems due to their extensive morphological and physiological adaptations. They play crucial roles in aquatic ecosystems as primary producers and resource providers but also pose significant ecological and health risks through blooms that produce harmful toxins ...
