THE IMPACT OF SEVERE WEATHER PHENOMENA ON KARENIA BREVIS

2010
The impact of 1995 Hurricane Erin on Karenia brevis, a red tide dinoflagellate, was studied from seawater samples collected from nine stations in Sarasota Bay, Florida. Comparison was made between samples collected before and after the passing of the storm. Data suggests that the hurricane may have had a positive impact on K. brevis growth.

Nutrient availability in support of Karenia brevis blooms on the central West Florida Shelf: What keeps Karenia blooming?

Continental Shelf Research, 2008
Abstract Identifying nutrient sources, primarily nitrogen (N) and phosphorus (P), sufficient to support high biomass blooms of the red tide dinoflagellate, Karenia brevis, has remained problematic. The West Florida Shelf is oligotrophic, yet populations >106 cells L−1 frequently occur and blooms can persist for months.

Monitoring of brevetoxins in the Karenia brevis bloom-exposed Eastern oyster (Crassostrea virginica)

Toxicon, 2008
Brevetoxin uptake and elimination were examined in Eastern oyster (Crassostrea virginica) exposed to recurring blooms of the marine alga Karenia brevis in Sarasota Bay, FL, over a three-year period. Brevetoxins were monitored by in vitro assays (ELISA, cytotoxicity assay, and receptor binding assay) and LC-MS, with in vivo toxicity of shellfish ...

Toxins and Biliary Atresia: Is Karenia Brevis (Red Tide) The Culprit?

Harmful Algae
The study objective was to evaluate the association between Karenia brevis (K. brevis) exposure during pregnancy and the prevalence of biliary atresia (BA) in offspring.This was a hospital-based, case-control study in which cases were infants diagnosed with BA at Johns Hopkins All Children's Hospital from October 2001 to December 2019.

Assessment of the sub-lethal impacts of Karenia brevis on hard clams, Mercenaria campechiensis

Harmful Algae
Karenia brevis, a toxin-producing dinoflagellate, has been implicated in frequent harmful algal blooms (HABs) in the Gulf of Mexico. Shellfish species, such as Mercenaria campechiensis, have high resilience to K. brevis exposure causing high accumulation and retention of brevetoxins within their tissues.
