Brevetoxin in two planktivorous fishes after exposure to Karenia brevis: implications for food-web transfer to bottlenose dolphins [PDF]

open access: yes, 2008
Brevetoxin uptake was analyzed in 2 common planktivorous fish that are likely foodweb vectors for dolphin mortality events associated with brevetoxin-producing red tides.

Inhalation toxicity of brevetoxin 3 in rats exposed for 5 days

open access: yes, 2004
Brevetoxins are potent neurotoxins produced by the marine dinoflagellate Karenia brevis. Exposure to brevetoxins may occur during a K. brevis red tide when the compounds become aerosolized by wind and surf.

Brevetoxin: How Is It Made and Why [PDF]

open access: yes, 2011
Karenia brevis is the major harmful algal bloom-forming species in the Gulf of Mexico, and produces neurotoxins, known as brevetoxins, that cause large fish kills, neurotoxic shellfish poisoning, and human respiratory distress. Brevetoxins are polyethers

Fusing Multi‐ and Hyperspectral Satellite Data for Harmful Algal Bloom Monitoring With Self‐Supervised and Hierarchical Deep Learning

open access: yesEarth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We present a self‐supervised machine learning framework for detecting and mapping the severity and speciation of harmful algal blooms (HABs) using multi‐sensor satellite data. By fusing reflectance data from operational polar‐orbiting satellite‐based instruments (VIIRS, MODIS, OLCI, and OCI) with TROPOMI solar‐induced fluorescence (SIF), our ...

Total Synthesis of Brevetoxin A

open access: yes, 2016
A total synthesis of brevetoxin A is reported. Two tetracyclic coupling partners, prepared from previously reported advanced fragments, were effectively united via a Horner−Wittig olefination.

Ladder-Shaped Ion Channel Ligands: Current State of Knowledge

open access: yesMarine Drugs, 2017
Ciguatoxins (CTX) and brevetoxins (BTX) are polycyclic ethereal compounds biosynthesized by the worldwide distributed planktonic and epibenthic dinoflagellates of Gambierdiscus and Karenia genera, correspondingly.

Seasonal Single-Site Sampling Reveals Large Diversity of Marine Algal Toxins in Coastal Waters and Shellfish of New Caledonia (Southwestern Pacific)

open access: yesToxins, 2023
Algal toxins pose a serious threat to human and coastal ecosystem health, even if their potential impacts are poorly documented in New Caledonia (NC).

Characterization of Interaction Between Brevetoxin and Its Native Receptor and Identification of the Role of Brevetoxin in Karenia brevis [PDF]

open access: yes, 2017
Algae are important to marine and fresh-water ecosystems. However, some species of algae are harmful or even toxic. They can consume oxygen or block sunlight that is essential for other organisms to live. Indeed, some algae blooms can produce toxins that

Chronic and punctuated changes in subtropical reef fish assemblages

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Understanding temporal changes in marine biodiversity is crucial for managing and conserving reef ecosystems in the face of global environmental shifts. Although biodiversity changes at global and regional scales often differ, the role of subtropical systems in these patterns has been relatively understudied until recently.

Predicting Karenia brevis Induced Respiratory Irritation at Individual Southwest Florida Beaches Using Cell Abundances Plus Wind Direction and Speed

open access: yesGeoHealth, Volume 10, Issue 4, April 2026.
Abstract Nearly annually, blooms of the dinoflagellate Karenia brevis form along the southwest Florida coast leading to a variety of negative impacts, including respiratory irritation (RI) in humans. To limit these impacts, NOAA's National Centers for Coastal Ocean Science (NCCOS) developed a RI model to provide beach‐goers with a category‐based ...
