Grazer‐induced bioluminescence and toxicity in marine dinoflagellates

Limnology and Oceanography, Volume 70, Issue 12, Page 3769-3783, December 2025.
Abstract Marine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production ...

Comparative paralytic shellfish toxin accumulation in three important Aotearoa New Zealand marine invertebrate species: kina (Evechinus chloroticus), pāua (Haliotis iris) and hohehohe (Panopea zelandica)

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1252-1264, December 2025.
ABSTRACT This study investigated the potential for paralytic shellfish toxin (PST) accumulation in three of Aotearoa New Zealand's (NZ) taonga seafood species: kina (urchin; Evechinus chloroticus), pāua (abalone; Haliotis iris) and hohehohe (geoduck; Panopea zelandica) in laboratory exposures to the dinoflagellate Alexandrium pacificum.

Modelling paralytic shellfish toxins (PSTs) transfer and accumulation in populations of two planktonic grazers

, 2013
A model was developed in this paper in order to study and compare the paralytic shellfish toxin (PST) transfer and accumulation of two different potential PST vectors in the planktonic community, the heterotrophic dinoflagellate in its red form Noctiluca

Evaluation of Rapid, Early Warning Approaches to Track Shellfish Toxins Associated with Dinophysis and Alexandrium Blooms

Marine Drugs, 2018
Marine biotoxin-contaminated seafood has caused thousands of poisonings worldwide this century. Given these threats, there is an increasing need for improved technologies that can be easily integrated into coastal monitoring programs.

Nutrient‐driven regulation of saxitoxin gene expression and toxin production in Raphidiopsis raciborskii (Cyanobacteria)

Journal of Phycology, Volume 61, Issue 6, Page 1738-1752, December 2025.
Abstract Raphidiopsis raciborskii is a diazotrophic cyanobacterium, globally distributed in aquatic environments and known for forming toxic blooms, thereby affecting ecosystem services. South American strains are producers of saxitoxins, potent neurotoxins harmful to humans and animals.

Development and Validation of a Liquid Chromatography-Tandem Mass Spectrometry Method Coupled with Dispersive Solid-Phase Extraction for Simultaneous Quantification of Eight Paralytic Shellfish Poisoning Toxins in Shellfish

, 2017
In this study, a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed for simultaneous determination of eight paralytic shellfish poisoning (PSP) toxins, including saxitoxin (STX), neosaxitoxin (NEO ...
