These harmful algal blooms release toxins into the water, making it unusable for not only humans, but also pets and wildlife. From the west coast of the United States to the northern Gulf of Alaska, Pseudo-nitzschia, a genus of diatoms, and Alexandrium, a genus of dinoflagellates, are similarly the culprit causing recent harmful algal blooms (HAB) events.

Since the 1990s, Lake Erie has seen a return of the seasonal harmful algal blooms (HAB) that were common before the passage of the United States Clean Water Act in 1972, a problem that many academic researchers link to intensive farming and the use of excess fertilizer in the Maumee River watershed (Obenour et al. Elevated pCO 2 and warming may promote algal growth and toxin production, and thereby possibly support the proliferation and toxicity of harmful algal blooms (HABs). Harmful algal blooms are one of the consequences of the human impact on aquatic ecosystems, particularly the process of eutrophication. Toxic dinoflagellate shellfish poisoning blooms. lieve that ecosystem-level e・ects from toxic algae are more pervasive than we realize, a・ecting multiple trophic levels, depending on the ecosystem and the toxin involved (Ramsdell et al., 2005).

Dinoflagellates are also major contributors of harmful algal blooms or HABs (a.k.a red tides), and some of them produce toxins. DHEC is currently monitoring a bloom on a portion of Lake Whelchel that has exceeded our state standards for microcystins. Harmful algal blooms can be used to illustrate important concepts in biology, ecology, marine science, data analysis, and more. Volvocales, Chlorococcales, Myxophyceae and several others occur in such a great abundance in water, that they colour the whole water either green or blue green and cause the death of fishes. Harmful algal blooms (HABs) occur when algal colonies rapidly reproduce, deplete the water of oxygen, and create large concentrations of natural biotoxins. The publication is edited by Michele A Burford - a member of the 6th Australian and New Zealand Cynaboacteria Workshop planning committee - along with Patricia M Gilbert, Elisa Berdalet, Grant C. Pitcher and Mingjiang Zhou.. This research is aimed at understanding massive accumulations of photosynthetic protists (microalgae) that sometimes occur in coastal waters. Research indicates that algae can by used by the agricultural industry in the production of fertilizers due to the high nutrient content. Contact. These are referred to by the scientific community as "Harmful Algal Blooms" or HABs. While some HABs occur naturally, others may be stimulated by human activities.

The Directorate for Geosciences, Division of Ocean Sciences invites proposals for cooperative research activities between United States and European researchers focused on the ecology and oceanography of harmful algal blooms. Furthermore, if these algal blooms are not grazed or diluted, their decomposition can deplete the dissolved oxygen in the water, causing the mortality of plants and animals. Lichen typically arises from algae and is in the algae plant family, but it can affect people and animals, and it’s usually harmful when it arises from Cyanobacteria, which is a type of algae. external icon Backer LC, Miller M.
