RNA Sequencing Revealed Numerous Polyketide Synthase Genes in the Harmful Dinoflagellate Karenia mikimotoi. [PDF]

PLoS ONE, 2015
The dinoflagellate Karenia mikimotoi forms blooms in the coastal waters of temperate regions and occasionally causes massive fish and invertebrate mortality. This study aimed to elucidate the toxic effect of K.

Machine Learning Classification Algorithms for Predicting Karenia brevis Blooms on the West Florida Shelf

Journal of Marine Science and Engineering, 2021
Harmful algal blooms (HABs), events that kill fish, impact human health in multiple ways, and contaminate water supplies, have increased in frequency, magnitude, and impacts in numerous marine and freshwaters around the world.

Are offshore phytoplankton susceptible to Karenia brevis allelopathy? [PDF]

Journal of Plankton Research, 2014
The bloom-forming dinoflagellate Karenia brevis produces a suite of allelopathic compounds that inhibit the growth of several phytoplankton competitors in laboratory experiments. However, it is less clear how allelopathy affects competition in the field, including whether allelopathic compounds impact K. brevis bloom dynamics.

Distinct, Depth-Stratified Communities of Heterotrophic, Mixotrophic, and Parasitic Dinoflagellates and Ciliates in the Subarctic Northeast Pacific Euphotic Zone. [PDF]

J Eukaryot Microbiol
ABSTRACT Dinoflagellates and ciliates are important grazers of primary production in the Northeast Pacific but knowledge of their taxonomic composition and depth‐distribution is limited. These organisms also display a variety of heterotrophic feeding modes including heterotrophy, mixotrophy, and parasitism.

Lessening the Hazards of Florida Red Tides: A Common Sense Approach

Frontiers in Marine Science, 2020
In the Gulf of Mexico, especially along the southwest Florida coast, blooms of the dinoflagellate Karenia brevis are a coastal natural hazard. The organism produces a potent class of toxins, known as brevetoxins, which are released following cell lysis ...

Precipitation, submarine groundwater discharge of nitrogen, and red tides along the southwest Florida Gulf coast

Heliyon, 2023
Blooms of the dinoflagellate Karenia brevis occur almost every year along the southwest Florida Gulf coast. Long-duration blooms with especially high concentrations of K.

Florida’s Harmful Algal Bloom (HAB) Problem: Escalating Risks to Human, Environmental and Economic Health With Climate Change

Frontiers in Ecology and Evolution, 2021
Harmful Algal Blooms (HABs) pose unique risks to the citizens, stakeholders, visitors, environment and economy of the state of Florida. Florida has been historically subjected to reoccurring blooms of the toxic marine dinoflagellate Karenia brevis (C. C.

Inhibitory mechanism of phthalate esters on Karenia brevis

Chemosphere, 2016
The occurrence of phthalate esters (PAEs), a class of widely used and environmentally prevalent chemicals, raises concern to environmental and human health globally. The PAEs have been demonstrated to inhibit algae growth, but the underlying mechanisms remain unclear.

Further Insights into Brevetoxin Metabolism by de Novo Radiolabeling

Toxins, 2014
The toxic dinoflagellate Karenia brevis, responsible for early harmful algal blooms in the Gulf of Mexico, produces many secondary metabolites, including potent neurotoxins called brevetoxins (PbTx).
