Red tides are caused by an explosive growth and accumulation of certain microscopic algae, predominantly dinoflagellates, in coastal waters. Some species of dinoflagellates produce toxins that are among the most potent known to man. These harmful algae blooms, or HABs for short, pose a serious and recurring threat to human health, wildlife, marine ecosystems, fisheries, coastal aesthetics and our economy. The most troublesome species in the Gulf of Mexico is Karenia brevis. Like other dinoflagellates these tiny, single-celled organisms photosynthesize using chlorophyll like a plant yet they are mobile with the use of two flagella that propel them through the water column.
Their dominant role of reproduction is ansexual-cell division –one cell divides into two cells, those two split into four and so on. Given the right conditions, the size of the population can rise rapidly. For a population to expand quickly and sustain itself over time requires the confluence of at least three basic factors:
