When the Red Tide Rolls In: A Red Tide Associated Angioedema Case Report
Clinical Practice and Cases in Emergency Medicine, 2021 Introduction: Histamine-mediated angioedema is a potentially life-threatening reaction following exposures that incite mast cell activation. In Florida, red tides are a frequent phenomenon caused by overgrowth of the harmful algae species Karenia brevis,

Benthic-pelagic coupling in sediment-associated populations of Karenia brevis [PDF]
Journal of Plankton Research, 2008 Nutrient delivery to populations of Karenia brevis in oligotrophic water columns in the Gulf of Mexico remains uncertain. Aggregations of K. brevis near the sediment-water interface suggest that cells derive nutrients from the sediment. Video of cells near the sediment suggest that cells either access nutrients that flux out of the sediment or migrate ...

Limnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.Abstract Curcumin, a natural plant product derived from Curcuma longa, was assessed as a mitigation technique against the toxic bloom‐forming dinoflagellate Karenia brevis in two mesocosm experiments taking place in 2022 and 2024. In these experiments, curcumin was applied at a dosage of 5 mg L−1 to K.

Modeled Karenia brevis accumulation in the vicinity of a coastal nutrient front [PDF]
Marine Ecology Progress Series, 2006 The alongshore independent distribution of Karenia brevis, a dominant harmful algal bloom dinoflagellate in the Gulf of Mexico, was investigated in a shelf environment using the Expanded Eulerian physical-biological modeling approach. The physical model included an ocean of variable depth with a frontal region at the 25 m isobath, and moderate ...

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.Abstract Quantitative measurements of phytoplankton community composition (PCC) are essential for understanding fisheries production, ocean nutrient cycling, and the export of particulate carbon to the ocean interior. However, these measurements are constrained in dynamic coastal waters due to the spatial‐temporal constraints of in situ sampling ...

Termination patterns of Karenia brevis blooms in the eastern Gulf of Mexico
, 2022 The factors governing the initiation and development of K. brevis blooms in the eastern Gulf of Mexico are fairly well understood, however the physical, chemical and biological factors underlying bloom transport and termination are not. The Florida Fish and Wildlife Conservation Commission’s HAB Monitoring database was analyzed from 1998 - 2021 for ...

Exocytic Mechanisms of Storage and Release of Brevetoxin in the Dinoflagellate Karenia Brevis [PDF]
Biophysical Journal, 2012 Karenia brevis is a broadly distributed toxic dinoflagellate responsible for Red Tide outbreaks throughout the world. Deleterious effects of these blooms are caused by brevetoxin, a potent neurotoxin that binds to sodium channels in nerve and muscle cell leading to substantial marine life mortality and human morbidity.

Limnology and Oceanography, Volume 70, Issue 9, Page 2603-2617, September 2025.Abstract The mixotrophic toxic dinoflagellate Karenia brevis forms red tides almost annually along Florida's Gulf coast. We hypothesize that the nutritional status and abundance of its prey, the picocyanobacterium Synechococcus, will affect its feeding rates and growth responses, with implications for bloom dynamics.

Algal toxins alter copepod feeding behavior. [PDF]
PLoS ONE, 2012 Using digital holographic cinematography, we quantify and compare the feeding behavior of free-swimming copepods, Acartia tonsa, on nutritional prey (Storeatula major) to that occurring during exposure to toxic and non-toxic strains of Karenia brevis and

An ecological framework for microbial metabolites in the ocean ecosystem
Limnology and Oceanography Letters, Volume 10, Issue 5, Page 636-659, September 2025.Abstract The ocean microbe‐metabolite network involves thousands of individual metabolites that encompass a breadth of chemical diversity and biological functions. These microbial metabolites mediate biogeochemical cycles, facilitate ecological relationships, and impact ecosystem health. While analytical advancements have begun to illuminate such roles,
