Data & Publications

A decade and a half of Pseudo-nitzschia spp. and domoic acid along the coast of southern California

Blooms of the marine diatom genus Pseudo-nitzschia that produce the neurotoxin domoic acid have been documented with regularity along the coast of southern California since 2003, with the occurrence of the toxin in shellfish tissue predating information on domoic acid ...

An unprecedented coastwide toxic algal bloom linked to anomalous ocean conditions

A coastwide bloom of the toxigenic diatom Pseudo-nitzschia in spring 2015 resulted in the largest recorded outbreak of the neurotoxin, domoic acid, along the North American west coast. Elevated toxins were measured in numerous stranded marine mammals and resulted in ...

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 Counties during spring and summer of 2003 and 2004. At least 1500 km2 ...

Blurred lines: Multiple freshwater and marine algal toxins at the land-sea interface of San Francisco Bay, California

San Francisco Bay (SFB) is a eutrophic estuary that harbors both freshwater and marine toxigenic organisms that are responsible for harmful algal blooms. While there are few commercial fishery harvests within SFB, recreational and subsistence harvesting for shellfish is common ...

Climatic regulation of the neurotoxin domoic acid

Domoic acid is a potent neurotoxin produced by certain marine microalgae that can accumulate in the foodweb, posing a health threat to human seafood consumers and wildlife in coastal regions worldwide. Evidence of climatic regulation of domoic acid in shellfish ...

Comparison of sandwich hybridization assay and quantitative PCR for the quantification of live and preserved cultures of Heterosigma akashiwo (Raphidophyceae)

In this study, we directly compared two molecular techniques, sandwich hybridization assay (SHA) and quantitative PCR (qPCR), for quantifying laboratory cultures of the ichthyotoxic raphidophyte Heterosigma akashiwo. To maximize comparisons, all experiments entailed raising H. akashiwo in the laboratory, generating ...

Effects of an Acute Hypoxic Event on Microplankton Community Structure in a Coastal Harbor of Southern California

Fish mortality and hypoxic events occur in many coastal and inland systems and may result from natural or anthropogenically mediated processes. The effects of consequent changes in water biogeochemistry have been investigated for communities of benthic invertebrates and pelagic metazoans ...

Effects of growth phase, diel cycle and macronutrient stress on the quantification of Heterosigma akashiwo using qPCR and SHA

The development of molecular probe technologies over the last several decades has enabled more rapid and specific identification and enumeration of phytoplankton species compared to traditional technologies, such as light microscopy. Direct comparisons of these methods with respect to physiological ...

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

Marine biotoxin-contaminated seafood has caused thousands of poisonings worldwide this century.
