Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...
A very large algae bloom in Lake Erie, North America, which can be seen from space. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in fresh water or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1]
One recent account suggests that the seasonal algal blooms in Lake Erie were possibly caused by runoff from cities, fertilizers, zebra mussels, and livestock near water. [82] A second report focuses on the zebra mussels as being the cause of dead zones, since they filter so much sediment that this produces an overgrowth of algae. [52]
Harmful Algal blooms are colonies of microscopic algae that grow out of control. They can be damaging to people, wildlife and the environment. How harmful algal blooms, or colonies of microscopic ...
Harmful algal blooms are caused by cyanobacteria, which sometimes can produce toxins called cyanotoxins that can be harmful to pets and people. Health officials investigating possible algal bloom ...
A restored swamp section in Bowling Green, Ohio.. During the second half of the 20th century, efforts were undertaken to preserve and restore portions of the swamp to its pre-settlement state (e.g. Limberlost Swamp) [11] After the excessive spread of harmful algal blooms in nearby western Lake Erie returned in 2011 and every year since then, there has been renewed interest in restoring ...
An algal bloom, sometimes referred to as a “red tide,” is a cluster of algae that forms when the water around it is warm, slow-moving and full of nutrients, according to the Centers for ...
Microcystis aeruginosa is a species of freshwater cyanobacteria that can form harmful algal blooms of economic and ecological importance. They are the most common toxic cyanobacterial bloom in eutrophic fresh water. Cyanobacteria produce neurotoxins and peptide hepatotoxins, such as microcystin and cyanopeptolin. [1]
