Environmental governance in the face of collapse: The case of Acapulco, Mexico, between tourist splendour and ecological risk

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater clean‐up efforts in Acapulco Bay reveal the visible consequences of chronic coastal pollution. This study shows how Environmental Risk Assessments (ERAs) can integrate scientific evidence, regulatory frameworks and practitioner experience to identify pollution sources and guide more effective coastal governance in cities of the Global South.

Statewide Intensification of Harmful Algal Blooms Across California Lakes and Reservoirs

GeoHealth, Volume 10, Issue 4, April 2026.
Abstract Monitoring cyanobacteria is crucial for assessing water quality, safeguarding public health, and understanding ecosystem dynamics impacted by harmful algal blooms. This study explores the potential of satellite remote sensing (SRS) to assess risks of cyanotoxin exposure in California's recreational waters from 2002 to 2011 and 2016 to 2023 ...

Screening the toxicity and toxin content of blooms of the cyanobacterium Trichodesmium erythraeum (Ehrenberg) in northeast Brasil

Journal of Venomous Animals and Toxins including Tropical Diseases, 2009
Blooms of the cyanobacterium Trichodesmium occur in massive colored patches over large areas of tropical and subtropical oceans. Recently, the interest in such events has increased given their role in major nitrogen and carbon dioxide oceanic fluxes ...

Saxitoxin time–resolved absorption and resonance FT–IR and Raman biospectroscopy and density functional theory investigation of vibronic–mode coupling structure in vibrational spectra analysis

American Journal of Experimental and Clinical Research, 2019
Saxitoxin (STX) is a potent neurotoxin and the best–known paralytic shellfish toxin (PST). Ingestion of Saxitoxin by humans, usually by consumption of shellfish contaminated by toxic algal blooms, is responsible for the illness known as paralytic ...

Molecular Mechanism of Mulberrin Regulating Lipid Metabolism Homeostasis Based on the Gut–Liver Axis Fiaf/AMPK Signaling Pathway

Food Frontiers, Volume 7, Issue 2, March 2026.
The molecular mechanism for mulberrin regulating lipid metabolism homeostasis. ABSTRACT Lipid metabolism disorders and the induced metabolic diseases have risen to become one of the primary public health issues. Our preliminary experimental results confirmed that mulberry leaf flavonoid extract exhibited efficacy in lipid metabolism regulation; the ...

eDNA Metabarcoding Reveals Microbial Community Composition in Tropical Mangrove Forests in Makassar, Indonesia

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study used environmental DNA (eDNA) metabarcoding with 18S rRNA markers to assess microbial diversity in the Lantebung Mangrove Forest, Makassar, Indonesia. It identified 103 microbial species across five kingdoms, revealing higher species richness in open‐water areas (P1) and greater individual abundance under mangrove canopy (P2).
