When the weather gets warmer, blue green algae appears on our canals, rivers and reservoirs. Repeated blooms Plants: Make their food by the process of photosynthesis. Water nutrient levels, exposure to light, temperature, turbidity and the general conditions found in a body of water all contribute — and they’re all different from site to site. It can be toxic if consumed, causes skin and respiratory irritation, and can be fatal to dogs that swim in or drink the water. What do you see? Asked by Wiki User. fish and amphibians. Blue–green algae prefer stable water conditions with low flows, long retention times, light winds and minimal turbulence. Cyanobacteria are an ancient group of organisms that were among the first life on earth, and were responsible for converting earth’s early atmosphere from an oxygen poor to an oxygen rich environment. 01. Algae also provide important habitats for invertebrates and fish. Blooms do occur naturally, but excessive nutrients and certain environmental conditions can cause larger growth. athlete's foot). can be supplemented by a variety of human activities. Although natural, human activities that cause an increase in algae or aquatic plant growth like the introduction of nitrogen or phosphorus fertilizers can cause plant and algae blooms and an increase in foam production along with the removal of oxygen as these plants decompose. Things used to be worse for many water bodies; phosphorus used to be an ingredient in laundry detergents, but this has generally been phased out. In water bodies, another consequence of stable conditions is thermal stratification. Thus, we are enlisting the 11 most common types of algae, their causes and their treatments for you. ; You typically will not see filamentous algae growing in the middle of a 20 foot deep water body because that is too deep for the sunlight to penetrate. decay. prior to being distributed to customers. other aquatic plants also can cause significant degradation of a lake or Algae help to ‘purify’ water by absorbing nutrients and heavy metals from streams and rivers. But in other cases, recurrent or severe blooms can Turner, and T. K. Kratz.

Water moves more slowly or becomes ponded, which encourages the growth of algae. That isn’t to say that humans haven’t had an impact. As algae forms, the water becomes increasingly turbid, which fosters an even stronger environment for algal blooms to thrive. Some algae produce an aromatic … This affects biodiversity and productivity of rivers. But these fertilizers and pesticides can be washed through the soil by rain, to end up in rivers. They can also occur in rivers, especially during summer months. Ecology, Fresh-Water Although large algae are removed by sediment filters at water treatment plants, tinier algae plants can make it past those filters as well as the subsequent filtration phases. 14 (1999):5–12. Algal blooms are natural occurrences, and may occur with regularity While duckweed is a less serious form of algae, Gansberg suggests people do not swim in it. Cyanobacterial toxins are known to affect bean photosynthesis when they lung irritations (if the toxin becomes aerosolized and hence airborne). Blue-green algae are so common because they have the ability to move throughout the water column and adapt to variable conditions. Answer . communities, reduce growth of trout, and interfere with development of The algae then destroy water plants.
