Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, Volume 44, Issue 6, Page 1013-1098, November/December 2025.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Distributed sensing devices for monitoring marine environment [PDF]

open access: yes, 2011
The lack of affordable, self-sustaining platforms for monitoring marine water quality means that measurements are done primarily through grab sampling at a limited number of locations and time, followed by analysis back at a centralised facility.

Guidance Level for Brevetoxins in French Shellfish

open access: yesMarine Drugs, 2021
Brevetoxins (BTXs) are marine biotoxins responsible for neurotoxic shellfish poisoning (NSP) after ingestion of contaminated shellfish. NSP is characterized by neurological, gastrointestinal and/or cardiovascular symptoms. The main known producer of BTXs

Reduced Adult Survival Estimated in Areas of Decline of Harbour Seal Populations in Scotland

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We applied mark–recapture models to photo‐ID data from harbour seals at three sites of contrasting population trajectories in Scotland and estimated apparent adult survival and fecundity rates. The results indicate that the causes of the decline are likely acting on adult survival, while evidence that a decrease in fecundity is driving the observed ...

The Continuing Saga of the Marine Polyether Biotoxins [PDF]

open access: yesAngewandte Chemie International Edition, 2008
AbstractThe unprecedented structure of the marine natural product brevetoxin B was elucidated by the research group of Nakanishi and Clardy in 1981. The ladderlike molecular architecture of this fused polyether molecule, its potent toxicity, and fascinating voltage‐sensitive sodium channel based mechanism of action immediately captured the imagination ...

Diversity of Amphidomataceae (Dinophyceae) in the Black Sea, including description of Amphidoma pontica sp. nov.

open access: yesPhycological Research, Volume 73, Issue 4, Page 225-248, October 2025.
SUMMARY The dinoflagellate family Amphidomataceae includes the genera Azadinium and Amphidoma, several species of which are known producers of lipophilic toxins known as azaspiracids (AZAs). However, the diversity, abundance, and distribution of this important group of nanoplanktonic dinoflagellates in the Black Sea remain poorly understood. To address

Surveillance Plan of Lipophilic Marine Biotoxins in Molluscs from the Croatian Coast

open access: yesExposure and Health, 2021
In the present study, a 4-year surveillance plan for the detection of lipophilic marine biotoxins in Mytilus galloprovincialis and Callista chione from different aquaculture farms and natural beds along the Central Adriatic coasts of Croatia was reported.

Inhibition of cosmopolitan toxic diatom, Pseudo‐nitzschia, by seaweeds

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2591-2602, September 2025.
Abstract Pseudo‐nitzschia is a genus of harmful algal bloom (HAB)‐forming diatoms that can produce domoic acid (DA), a compound known to cause death and disease in marine wildlife as well as amnesic shellfish poisoning in humans. Here, we show the effects of multiple cultivable seaweeds—Saccharina latissima (sugar kelp), Ulva spp., and Gracilaria spp ...

Long‐term change and seasonal spillover risks of fatal acanthocephalan infection in southern sea otters

open access: yesEcosphere, Volume 16, Issue 8, August 2025.
Abstract Southern sea otters (Enhydra lutris nereis) face numerous risks to population recovery from infectious disease, shark attacks, and biotoxins. Recently, the most significant contributor to fatal infectious disease in sea otters has been acanthocephalan peritonitis (AP) caused by Profilicollis altmani.
