A type of microscopic algae called Karenia brevis has grown rapidly in Florida, leaving dead fish on the shore. Harmful “red tide” is wreaking smelly havoc on Florida’s Gulf Coast, canceling ...
Karenia brevis blooms have been in the Gulf of Mexico for hundreds of years as documented by fish kills, toxic shellfish, aerosols. They will be here for some time to come.
Karenia brevis produce what are known as brevetoxins, which can kill marine life and birds. The red tide organism can also cause health problems in humans, such as skin irritation.
But the Florida Fish and Wildlife Conservation Commission says Karenia brevis, the microorganism responsible for red tide, was not identified until 1946. The blooms don’t necessarily have to be ...
Karenia brevis is, however, a particularly nasty one; its outbreaks have afflicted the coast of Florida since as far back as the 1500s, and now do so almost every year to varying degrees.
Karenia brevis’ genome is 33 times larger than the human genome, and scientists know very little about its makeup because it has not yet been sequenced. Grow your mind.
Karenia brevis can utilize at least 13 different sources of nutrients, including multiple forms of nitrogen and phosphorus. They also discussed a need for determining what qualifies as a bloom.
The reddish plankton Karenia brevis grows throughout the Gulf of Mexico. Occasionally, in autumn, it forms dense blooms that contain a nerve toxin. The toxin renders shellfish inedible and makes ...
A type of toxic algae, Karenia brevis, ... K. brevis is increasing in Florida’s waters, more abundant year-round now than in the 1950s, most likely because of higher nutrients.
Understanding the dinoflagellates that regularly wreak havoc on marine and nearshore ecosystems in the Gulf of Mexico could help researchers mitigate the damage they cause. A full description of the ...
