Sea lion mortalities in central California during May and June 1998 were traced to their ingestion of sardines and anchovies that had accumulated the neurotoxin domoic acid. The detection of toxin in urine, feces, and stomach contents of several sea lions represents the first proven occurrence of domoic acid transfer through the food chain to a marine mammal. The pennate diatoms, Pseudo-nitzschia multiseriesand P. australis, were the dominant, toxinproducing phytoplankton constituting algal… Expand

Figures and Tables from this paper

Domoic acid in benthic flatfish on the continental shelf of Monterey Bay, California, USA
TLDR
Curlfin turbot, Pleuronicthys decurrens, the flatfish with both the highest level and frequency of DA contamination, are reported to feed exclusively on polychaetes, suggesting that these invertebrates may be an important vector of the toxin in benthic communities and may pose a risk to other bentho-feeding organisms.

Biological and physical dynamics of domoic acid production off the Washington coast
The relationship among Pseudo-nitzschia distributions, particulate toxin levels in seawater, and the energetic and highly variable water masses of an upwelling-dominated region are explored usingExpand
A decade and a half of Pseudo-nitzschia spp. and domoic acid along the coast of southern California.
TLDR
The general oceanographic factors leading to blooms of Pseudo-nitzschia and outbreaks of domoic acid in this region are clear, but subtle factors controlling spatial and interannual variability in bloom magnitude and toxin production remain elusive. Expand
Blooms of Pseudo-nitzschia and domoic acid in the San Pedro Channel and Los Angeles harbor areas of the Southern California Bight, 2003-2004
Abundances of Pseudo-nitzschia spp. and concentrations of particulate domoic acid (DA) were determined in the Southern California Bight (SCB) along the coasts of Los Angeles and Orange CountiesExpand
An unprecedented coastwide toxic algal bloom linked to anomalous ocean conditions
TLDR
It is demonstrated that this outbreak of the neurotoxin domoic acid along the North American west coast in spring 2015 was initiated by anomalously warm ocean conditions, and has the potential for similarly devastating ecological and economic disruptions in the future. Expand
Coastal upwelling linked to toxic Pseudo-nitzschia australis blooms in Los Angeles coastal waters, 2005–2007
Harmful algal blooms dominated by the diatom Pseudo-nitzschia spp. have become a perennial but variable event within surface waters near the greater Los Angeles area. Toxic blooms during springExpand
Characterization of a toxic Pseudo-nitzschia spp. bloom in the Northern Gulf of Mexico associated with domoic acid accumulation in fish
TLDR
This is the first demonstration of trophic transfer of DA in this region of the NGOM, indicating that toxic blooms of Pseudo-nitzschia spp. Expand
Circulation and environmental conditions during a toxigenic Pseudo-nitzschia australis bloom in the Santa Barbara Channel, California
During May 2003, a toxigenic bloom of the diatom Pseudo-nitzschia australis occurred in the Santa Barbara Channel (SBC), California, that was linked to a marine mammal mortality event in the region.Expand

Mortality of sea lions along the central California coast linked to a toxic diatom bloom
TLDR
Findings reveal that monitoring of mussel toxicity alone does not necessarily provide adequate warning of DA entering the food web at levels sufficient to harm marine wildlife and perhaps humans. Expand
Detection of domoic acid in northern anchovies and California sea lions associated with an unusual mortality event.
TLDR
The authors' detection of P. australis frustules, via scanning electron microscopy, in both anchovy viscera and fecal material from sea lions exhibiting seizures provides corroborating evidence that this toxic algal species was involved in this unusual sea lion mortality event. Expand
Domoic acid-producing diatom blooms in Monterey Bay, California: 1991-1993.
TLDR
This study suggests that P. australis cells may always be toxic in natural populations and that toxin concentrations on a per cell basis have no statistically significant relationship to population density or to nutrient concentrations other than silicate. Expand

Occurrence of domoic acid in Washington state razor clams (Siliqua patula) during 1991-1993.
TLDR
Analysis of Washington State razor clams for the period from November 1991 to June 1993 indicated that domoic acid levels in the edible portion of the razor clam peaked in December of 1991 and followed a slow decline to the present day low levels (< 5 ppm). Expand
AN OUTBREAK OF DOMOIC ACID POISONING ATTRIBUTED TO THE PENNATE DIATOM PSEUDONITZSCHIA AUSTRALIS 1
TLDR
This is the first confirmed report of DA poisoning since the original 1987 episode in Atlantic Canada caused by Nitzschia pungens Grunow forma multiseries Hasle, and suggests another species of planktonic pennate diatom is capable of producing DA and that herbivorous finfish can act as vectors for this toxin.

Concentration and dispersal of a Pseudo-nitzschia bloom in Penn Cove, Washington, USA.
TLDR
A bloom of the pennate diatom Pseudo-nitzschia, several species of which are associated with the production of the potent excitotoxin domoic acid, was observed in a Puget Sound, Washington embayment in July and August of 1997, aiding in the development of a model for prediction of toxic bloom events in the shallow embayments of Pugetsound.

Persistent “upwelling shadows” and their influence on zooplankton distributions
TLDR
Zooplankton-assemblage analysis confirmed the presence of two distinct regions in northern Monterey Bay, which is the result of the advection of recently upwelled water bearing nutrients and larvae past coastal recesses which are equatorward of upwelling centers. Expand
