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.

Dynamic photo-physiological responses of the dinoflagellate Karenia brevis to short-term changes in temperature and nitrogen substrates

, 2022
On the West Florida Shelf, annual blooms of the neurotoxin-producing harmful dinoflagellate, Karenia brevis (and other Karenia species) cause negative effects on the environment, the economy, and on human health. Blooms primarily occur in the fall months

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.

Lack of mixotrophy in three Karenia species and the prey spectrum of Karenia mikimotoi (Gymnodiniales, Dinophyceae)

, 2023
Exploring mixotrophy of dinoflagellate species is critical to understanding red-tide dynamics and dinoflagellate evolu-tion. Some species in the dinoflagellate genus Karenia have caused harmful algal blooms.

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).

First Case of Brevetoxicosis Linked to Rough-Toothed Dolphin (Steno bredanensis) Mass-Mortality Event in Eastern Central Atlantic Ocean: A Climate Change Effect?

Frontiers in Marine Science, 2022
Harmful algal blooms (HABs) have been increasingly recorded over the last decades and much work has linked these events to multiple oceanographic and climate disturbances.

Utility of Red Tide (Karenia brevis) Monitoring Data as a Predictive Tool to Estimate Brevetoxin Accumulation in Live, Free-Ranging Marine Mammals

Frontiers in Marine Science, 2021
Exposure of common bottlenose dolphins (Tursiops truncatus) to brevetoxins (PbTx) produced by blooms of the toxic phytoplankton Karenia brevis frequently results in severe health impacts, including illness and large-scale mortality events.
