A form of invasive toxic freshwater algal bloom known as blue-green is caused by what?
Algal bloom green blooms in freshwater systems are frequently a result of cyanobacteria (colloquially known as "blue-green algae" as a result of their confusing taxonomical history) such as "Microcystis". Blooms may also consist of macroalgal (non-phytoplanktonic) species. These blooms are recognizable by large blades of algae that may wash up onto the shoreline. Of particular note are the rare harmful algal blooms (HABs), which are algal bloom events involving toxic or otherwise harmful phytoplankton such as dinoflagellates of the genus "Alexandrium" and "Karenia", or diatoms of the genus "Pseudo-nitzschia". Such blooms often take on a red or brown hue and are known
Harmful Algal Bloom and Hypoxia Research and Control Amendments Act of 2013 accumulation in the population of algae (typically microscopic) in an aquatic system. Algal blooms may occur in freshwater as well as marine environments. Freshwater algal blooms are the result of an excess of nutrients, particularly some phosphates. Harmful algal blooms are algal bloom events involving toxic or otherwise harmful phytoplankton such as dinoflagellates of the genus "Alexandrium" and "Karenia" or diatoms of the genus "Pseudo-nitzschia". is an algal bloom that causes negative impacts to other organisms via production of natural toxins, mechanical damage to other organisms, or by other means. HABs are often associated with large-scale marine mortality events and
