Contemporary Foraging of the Hawaiian Monk Seal as a Retrospective Lens for Commercial Fishing and Its Relevance to Ecosystem‐Based Fishery Management

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT This retrospective analysis explores how historical fishing activity (1948–2009) at French Frigate Shoals (FFS) can be examined in relation to the foraging ecology of Hawaiian monk seals. We bring together fisheries catch records, monk seal demographic information, and ecological studies on prey, competitors, and predators to evaluate ...

Gambierone and Sodium Channel Specific Bioactivity Are Associated with the Extracellular Metabolite Pool of the Marine Dinoflagellate Coolia palmyrensis

Marine Drugs, 2023
Tropical epibenthic dinoflagellate communities produce a plethora of bioactive secondary metabolites, including the toxins ciguatoxins (CTXs) and potentially gambierones, that can contaminate fishes, leading to ciguatera poisoning (CP) when consumed by ...

Transcriptomic Analysis of Ciguatoxin-Induced Changes in Gene Expression in Primary Cultures of Mice Cortical Neurons

Toxins, 2018
Ciguatoxins are polyether marine toxins that act as sodium channel activators. These toxins cause ciguatera, one of the most widespread nonbacterial forms of food poisoning, which presents several symptoms in humans including long-term neurological ...

Incorporating Climate Change Impacts Within Harvest Strategies: An Overview of Approaches

Fish and Fisheries, Volume 26, Issue 5, Page 942-956, September 2025.
ABSTRACT Ensuring that harvest strategies are robust to climate change is a top priority for many fisheries jurisdictions globally. This is because climate change is altering ecosystem structure and the productivity of marine species. We outline a range of approaches for incorporating climate change impacts within harvest strategies, including how a ...

LC–HRMS and Chemical Derivatization Strategies for the Structure Elucidation of Caribbean Ciguatoxins: Identification of C-CTX-3 and -4

Marine Drugs, 2020
Ciguatera poisoning is linked to the ingestion of seafood that is contaminated with ciguatoxins (CTXs). The structural variability of these polyether toxins in nature remains poorly understood due to the low concentrations present even in highly toxic ...

Identification of New CTX Analogues in Fish from the Madeira and Selvagens Archipelagos by Neuro-2a CBA and LC-HRMS

Marine Drugs, 2022
Ciguatera Poisoning (CP) is caused by consumption of fish or invertebrates contaminated with ciguatoxins (CTXs). Presently CP is a public concern in some temperate regions, such as Macaronesia (North-Eastern Atlantic Ocean).

Effects of El Niño and the Positive Indian Ocean Dipole (+IOD) on Health, Food Security, Economics, and Conflict in Low‐ and Middle‐Income Countries in the Indo‐Pacific: A Systematic Review

Campbell Systematic Reviews, Volume 21, Issue 2, June 2025.
ABSTRACT Climate drivers such as the El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) can impact multiple sectors globally. We are currently witnessing the effects of these teleconnections against the backdrop of a changing climate. This systematic review takes stock of the available evidence on compounding and cascading effects of
