Lesser-Known Cyanotoxins: A Comprehensive Review of Their Health and Environmental Impacts

Toxins
Cyanobacteria, also known as blue-green algae, are a diverse phylum of photosynthetic, Gram-negative bacteria and one of the largest microbial taxa. These organisms produce cyanotoxins, which are secondary metabolites that can have significant impacts on

Microbial mats and thalassinid shrimp: Spatial and geochemical interactions in a modern intertidal environment

Sedimentology, EarlyView.
ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Stability of cyanotoxins, microcystin-LR, microcystin-RR and nodularin in seawater and BG-11 medium of different salinity

Oceanologia, 2001
Microcystins and nodularin are potent hepatotoxins produced by fresh and seawater cyanobacteria. The persistence of three hepatotoxins - microcystin-LR, microcystin-RR and nodularin - was investigated in sterile BG-11 medium of different salinity and in ...

“Is This Edible Anyway?” The Impact of Culture on the Evolution (and Devolution) of Mushroom Knowledge

Topics in Cognitive Science, EarlyView.
Abstract Mushrooms are a ubiquitous and essential component in our biological environment and have been of interest to humans around the globe for millennia. Knowledge about mushrooms represents a prime example of cumulative culture, one of the key processes in human evolution.

Fertilizers Effect Blue Green Algae and increasing their Toxins

International Journal of Bio-Resource and Stress Management, 2018
Urban activities add pollutants to the environment, and increase  Phosphorous [P], Nitrogen [N], Sulfate [S] and Iron [Fe], these pollutants in Aquatic environment can cause Eutrophication of Blue green algae (BGA), which they are an auto nutrition ...

The Quality of Clarity: Lessons from the Sixty‐Year Struggle to Maintain the Purity of Lake Taupō

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.
Sixty years of effort to protect the exceptionally clear water of Lake Taupō, the largest lake in Aotearoa New Zealand, show how environmental memory can help manage a cultural and natural resource. I describe how water clarity and quality in this lake have been protected, through managing soil erosion and phosphorus flows during the 1960s–1980s, and ...

Genome‐Wide In Silico Analysis of the Type VI Secretion System (T6SS) Within the Morganella Genus

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
▪ Species‐specific T6SS patterns among Morganella genus (M. morganii and M. sibonii). ▪ Only one‐third of M. morganii isolates haboured a T6SS. ▪ All M. sibonii possess four T6SS clusters. ▪ M. sibonii exhibited a wide diversity of effectors compared to M. morganii.

Solid Olive‐Mill Waste and Biochar Effects on the Bioavailability and Bioactivity of Abscisic Acid in Soil

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
Biochar and solid olive‐mill waste differently affected abscisic acid (ABA) bioavailability and bioactivity in soil by altering ABA sorption and soil chemical and microbial properties. The type of amendment and the mechanisms by which it affected ABA bioavailability in soil were key determinants of the final effects on ABA bioactivity. ABSTRACT Natural

Cyanobacteria and toxins detection. A review

, 2001
Water environment eutrophication increases the risk of harmful bloom development, like cyanobacterial blooms, which can produce potent toxins able to affect public and animal health. More than 50% of the cyanobacterial proliferation are toxic. Both toxigenic (toxin producers) and non-toxigenic strains, may exist within a single specie of cyanobacteria.

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

New Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...
