Eutrophication

In this case study, scientists researched Lepomis microlophus (redear sunfish), Lepomis macrochirus (bluegill sunfish), and Microterpus salmoides (largemouth bass) that were collected from control ponds, natural lakes, and stormwater ponds in Orlando Florida. The fish were analyzed heavy metals such as zinc, lead, copper, cadmium, and nickel. The purpose of the study was to determine if the fish from the stormwater ponds had higher concentrations of these metals, and if there was a difference…

As Benzie County evolves and grows the roots of the community stay. As our waterways have been used for shipping and logging over many generations they have also been used as a place of home, for salmon. In such a small place of the world such a large ecosystem full of beauty lies beneath the water where few get to experience its perplexing style. I am fortunate to grow up live in such a water driven environment where I can understand nature to the ability of a human. The Chinook Salmon was…

The water quality of the U-High creek was excellent, however not all creeks have excellent water quality. One way that a creek could get polluted, is the farmers who live and plant their crops near-by. The crops that they plant need to be protected and helped to grow. By doing those things the farmer uses fertilizers and pesticides, which as rain falls and washes away these chemicals, into near-by creeks. The problem with that is, the fertilizers, which contain large amounts of nitrates and…

One of the world’s most beautiful lakes is slowly deteriorating right before our eyes, yet hardly anything is being done. In rural Guatemala, landfills are almost full, so locals burn their trash to get rid of it, and what they do not burn they just leave outside their homes. This leads to many contaminants and pollutants filtering into surrounding lakes. This causes severe damage to the lakes and to everything that depend on those lakes. One of those lakes, Lake Atitlán, was once described…

Water pollution is arguably the worst, or one of the worst forms of pollution affecting the world today. Take a look into a glass of tap water, looks clean right? From the naked eye, tap water looks clear, yet there are millions of microscopic contaminants in that single glass of water. Depending on where one lives, receives their water, and the environment around them, determines the purity of the water. Water pollution can be devastating to the environment, affects economics, and alters people…

Introduction Phosphorus is one of the key elements necessary for the growth of plants and animals (1). That is why having the right levels of phosphorous in the water is so essential. If too much phosphate is present in the water the algae and weeds will grow rapidly, may choke the waterway, and use up large amounts of precious oxygen (in the absence of photosynthesis and as the algae and plants die and are consumed by aerobic bacteria.) The result may be the death of many fish and aquatic…

First, the runoff going into Lake Erie must be reduced. The major area of runoff comes from farms. The cause for runoff is rain and the rain washes away all pesticides, which enter into lakes and rivers: “In both cases, heavy spring rains washed away tons of fertilizer from farms. The runoff drained into rivers that fed the lake. Phosphorus in the fertilizer spurred cyanobacteria growth. Hot summers and other factors made matters worse” (Kowalski 34). As a result of pesticide entering into lakes…

The water quality of the U-High Creek has been tested to be excellent. However, that does not mean that every creek is pure or excellent. Some people, more specifically farmers, use fertilizers made from Nitrogen and Phosphorus to kill pests or bugs. Little do they know, the pesticide or fertilizers get into streams and creeks and contaminate it leaving algae growing more rapidly or consistently. Consequently, if the algae overfills the creek, organisms will then die out from oxygen shortage…

Competition Of Resources In The Campus Lakes General Research Question: Will competition affect resources available in Campus Lakes? Population Ecology Experiment Null Hypothesis: The presence of blue-green algae will not have on effect on the Chlamydomonas population. Alternative Hypothesis: The presence of blue-green algae will have an effect on the Chlamydomonas population. Community Ecology Experiment Null Hypothesis: Nitrate concentration will not have an effect on chlorophyll levels in…

Lake Winnipeg article Algae Contaminates Lake Winnipeg! Algal bloom a big issue Prabhnoor Brar, Toronto Star Lake Winnipeg is dying from algae,everyday, soap is getting dumped into sewage pipes which goes to lake winnipeg. Almost everyone helps making lake Winnipeg polluted without knowing. Most people don't even know how their polluting, but they are when the soap goes down the sewage pipes. The algae spreading was not really noticed, but when most of the fish died and fishers…
