calculated the measurements of phosphate for a eutrophic (high and nutrients) and hypertrophic (extremely high in nutrients) environment using the formula, Gross weight- Tare weight divided by volume, provided in French (2015). We decided to test a hypertrophic environment to see if it was possible to return it to eutrophic and then eventually a mesotrophic environment. For our eutrophic environment, we measured out 12µL of phosphate for our eutrophic and 120µL of phosphate for our hypertrophic environment
nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers). Harrison describes Eutrophic lakes as highly productive and turbid due to algae being present. Furthermore Harrison states that oligotrophic lakes have low productivity and are clear in the
the trophic state index, the weight of biomass can be determined (Carlson, 1976). The trophic status of a lake will help determine the nutrition and growth of a lake. There are three classifications: oligotrophic, mesotrophic and eutrophic (Carlson, 1976). A eutrophic lake has a high nutrient content and high plant growth, a mesotrophic is in the middle, and an oligotrophic lake has a low nutrient content and low plant growth (Carlson, 1976). Performing this lab and being able to determine the
risk. Frogs located in certain eutrophic waters (where Ribeiroia ondatra are present) are having to face a higher risk of contracting the parasite which could devastate populations globally. Even worse, they believe that snails may continually compound the effects of eutrophication for years to come; elevating the risk even higher for frogs as time goes on. The authors state that this risk is also heightened by wetland loss as these frogs may have to relocate to eutrophic habitats where these parasites
We obtained our samples from two locations, firstly, in the Amazon Lake, it is a eutrophic lake, so that means that it has life, probably algae and plankton. Lastly, we obtained another sample from the Giraffe Enclosure, which the water can have urine or excrement from the Giraffes. After a week or so, in the Day Thursday, November 30th
Euglena gracilis, a species of single-celled photosynthetic eukaryotic algae from the genus Euglena, are found in freshwater environments such as eutrophic ponds (Farmer 1980). A key characteristic of E. gracilis are their two flagella, one of which is used for locomotion. These eukaryotic algae undergo cell division asexually in the dark (Farmer 1980). A study done by Professor Michael A. Sleigh of the Department of Biology at the University of Southampton, England shows that E. gracilis grow at
temperatures (Taylor 2011) .It was also seen that fertilisers contained nutrients, such as nitrates, which greatly influences duckweed growth. Duckweed is also used for feed for farm animal, such as ducks, and it is also used to reduce nutrients in eutrophic environments (Ansari and Khan 2008, 2009, 2011); therefore this experiment was done to determine the effects that high concentrations of fertilisers cause on Duckweed by repeatedly adding varying
They are common occupants in freshwater ecosystems like eutrophic lakes, rockpools, ponds but also in more brackish waters (Ambler, Cloern, & Hutchinson, 1985; Hebert, 1978). As outlined before, these habitats are unpredictable with wide fluctuations in abiotic factors, for example in salinity, temperature, acidity
American Government’s Impact on Energy. Climate Change, Pollution, and the Environment The modern world faces many environmental issues impacting water, air, and life on earth. The Funk and Wagnalls New World Encyclopedia defines pollution as the “contamination of air, water, or soil by materials that interfere with human health, the quality of life, or the natural functioning of ecosystems. For pollution of the atmosphere by emissions from industrial plants, incinerators, internal-combustion engines
Duckweed is one of the smallest flowering aquatic plants and is present in fresh water or wetland habitats. Though it looks mundane, there is an intricate biological mechanism which is affected by factors such as limiting factors, carrying capacity, logistic and exponential population growth, density dependent and density independent limiting factors, competition, interspecific and intraspecific competition, and optimal growth conditions. All of these will be discussed in this essay to understand
treatment. Some people believe that methadone treatment is unnecessary and that addicts should have to get over their addiction themselves rather than use other drugs to help. People can get addicted to methadone even though it does not produce an eutrophic high and some people say that withdrawing from methadone is worse than withdrawals from heroin. Methadone is a very dangerous drug and the doses have to be monitored carefully to prevent overdose and also to prevent withdrawal symptoms. Many people
1. It is a scientific fact that biodiversity is greatest near coral reefs and estuaries. But because of human influence coral reefs around the world are dying. Human coastal development, pollution, ocean warming, and ocean acidification are all things that threaten them. The World Research Institute estimated that about ¾ of the worlds shallow reefs are threatened by climate change, pollution, and overfishing. All in which are man made influences that affect the ocean greatly. It is predicted that
