Zooplankton and Karenia brevis in the Gulf of Mexico

Continental Shelf Research, 2008
Blooms of the toxic dinoflagellate Karenia brevis are common in the Gulf of Mexico, yet no in situ studies of zooplankton and K. brevis have been conducted there. Zooplankton abundance and taxonomic composition at non-bloom and K. brevis bloom stations within the Ecology of Harmful Algal Blooms (ECOHAB) study area were compared.

Insights into cell loss processes of toxic dinoflagellate Karenia brevis [PDF]

, 2020
Karenia brevis is responsible for annual harmful algal bloom (HAB) events in the Gulf of Mexico (GoM). Although the factors regulating the initiation of K. brevis blooms have been extensively investigated, the mechanisms leading to bloom decline and termination are not well known. Understanding the triggers of bloom decline could enhance our ability to

On the remote monitoring of Karenia brevis blooms of the west Florida shelf

Continental Shelf Research, 2008
Abstract In situ surveys (1997–2002) of Karenia brevis distribution on the west Florida shelf were used to explain spectral remote sensing reflectance, chlorophyll- a concentration, and backscattering coefficient estimates derived using SeaWiFS satellite data. Two existing approaches were tested in an attempt to differentiate K.

The effects of moderate concentrations of Karenia brevis on stone crab reproduction

Marine Environmental Research, 2023
The stone crab, Menippe mercenaria, supports a commercial fishery along Florida's Gulf coast where harmful algae blooms, known as red tides (Karenia brevis) develop. Red tides occur nearly annually and can overlap with the stone crab reproductive season. We determined the impact of moderate red tide (K.

Geospatial distribution of hypoxia associated with a Karenia brevis bloom

Estuarine, Coastal and Shelf Science, 2021
Abstract In 2018, the presence of bottom water hypoxia along the SW Florida coast was investigated during a bloom of the toxic dinoflagellate Karenia brevis. The bloom was first detected in November 2017. Monitoring of oxygen levels and bloom densities was carried out in 2018 and 2019 using sampling grids.

Use of dissolved inorganic and organic phosphorus by axenic and nonaxenic clones of Karenia brevis and Karenia mikimotoi

Harmful Algae, 2015
Nearly annual blooms of the marine dinoflagellate Karenia brevis, which initiate offshore on the West Florida Shelf in oligotrophic waters, cause widespread environmental and economic damage. The success of K. brevis as a bloom-former is partially attributed to its ability to use a diverse suite of nutrients from natural and anthropogenic sources ...

Mitigation of Karenia brevis Cells and Brevetoxins Using Curcumin, a Natural Supplement

Water (Switzerland)
Curcumin, a natural plant product, was investigated as a mitigation tool against Karenia brevis, the toxic dinoflagellate responsible for Florida red tides. A series of laboratory bench-top studies were conducted with additions of 0.1, 1, 2, 3, 5, 10, 20,

Transcriptome remodeling associated with chronological aging in the dinoflagellate, Karenia brevis

Marine Genomics, 2012
The toxic dinoflagellate, Karenia brevis, forms dense blooms in the Gulf of Mexico that persist for many months in coastal waters, where they can cause extensive marine animal mortalities and human health impacts. The mechanisms that enable cell survival in high density, low growth blooms, and the mechanisms leading to often rapid bloom demise are not ...
