Stressed Induced Changes in <i>Karenia brevis</i> Ribosomal RNA
<p><em>Karenia brevis</em> is a toxic marine dinoflagellate that causes harmful algal blooms (HABs), also known as red tides, in the Gulf of Mexico. These blooms are responsible for massive fish kills, shellfish bed contaminations, adverse human health effects, and vast economic loss. For these …

Identifying and Characterizing Non-Coding RNAs in the Dinoflagellate <i>Karenia brevis</i>
… on human, environmental and economic health. Karenia brevis, a mixotrophic dinoflagellate, forms HABs, and blooms caused by this organism have been known to remain several months after formation. For these reasons, research has been conducted to discover those factors that are responsible for …

Characterizing Populations of Non-Coding RNAs in <i>Karenia brevis</i> at Different Times of the Diel Cycle
<p><em>Karenia brevis </em>is a mixotrophic, marine dinoflagellate found in the Gulf of Mexico that generates periodic, if not annual, harmful algal blooms (also known as “red tides”) in certain coastal areas. In an effort to better understand the biology of this organism, a functional genomics …

Grazing on <i>Synechococcus spp.</i> by the Red-Tide Dinoflagellate <i>Karenia brevis</i>: Implications for Bloom Dynamics in the Gulf of Mexico
<p><em>Karenia brevis</em>, the toxic dinoflagellate responsible for massive red tides in the Gulf of Mexico (GOM), causes fish kills, shellfish poisoning, and acute respiratory irritation in humans. Bloom initiation and maintenance have been linked to the physical environment as well as various …

The aggregation of clay minerals and marine microalgal cells : physicochemical theory and implications for controlling harmful algal blooms
… clays were tested against the dinoflagellate, Karenia brevis (formerly Gymnodinium breve), and the chrysophyte, Aureococcus anophagefferens. In general, the highest removal efficiencies (RE>90% at 0.25 g l-1 of clay) against K brevis were found using montmorillonite, bentonite and phosphatic …

Nutrient Distribution Effects from Freshwater Discharge at Franklin Lock and Dam (S-79) in 2005 and 2006 on the Caloosahatchee Estuary and San Carlos Bay, Fort Myers, Florida
… 1.24 to 9.62 µg l-¹ in June through August 2006. Karenia brevis blooms were also present during this time. Nutrient loading rates into SCB provided enough DIN and DON to support the maintenance of K. brevis. Therefore monitoring and studying the amount of nutrient loading into coastal and offshore …

Phytoplankton Response to South Louisiana Crude Oil Exposure: Determining Impacts at Individual, Community, Toxin Production, Enzymatic-Activity and Gene-Expression Levels
… toxic phytoplankton species of the GoM, Karenia brevis and Prorocentrum minimum. It was revealed that reactive oxygen species are activated in phytoplankton exposed to crude oil. Phytoplankton species also displayed signs of oxidative stress and damage in their lipid structure under crude …
