should be paying attention to Daphnia Magna is because of pollution in our lakes. This pollution can affect a lot of actions that we do in our daily lives. Pollution can lead to mutations in fish, frogs and other animals that live in water. This can affect our food supply as well as the quality of the food we eat. Another reason recognizing pollution in lakes is a good idea is that it is the first step in reducing pollution in lakes. In the beginning of this project I was looking for a way to…
The five Great Lakes; Lake Superior, Lake Huron, Lake Ontario, Lake Michigan, and Lake Erie together form the largest freshwater source in the world. The Great Lakes are home to many animals and essential resource to living creatures. Life would be very different without the Great Lakes. The Great Lakes are an important part of Canadians resource. They are currently being destroyed by pollution, overfishing, chemical waste and climate change. Economically, without the Great Lakes, Canada would…
the beautiful Great Lakes as well. Samples from Lake Erie have an enormous amount of plastic particles. Most of these samples were microplastics, (Sigler pg.15). Andrew Reeves, a professor of political science, states, “A substantial portion of the floating Great Lakes plastic comes from exfoliating microbeads found in facial scrubs,” (Reeves pg.3).…
the Great Lakes are the amount of phosphorus nitrogen and fertilizer running off into the lake. When the lake becomes rich in these nutrients and you add warmer temperatures into the equation you can expect an algal bloom. Once the bloom dies the decomposition depletes much of the oxygen in the water which is severe because of the size of the algal bloom. This coupled with things such as low water inflow and temperature of water are the most popularly believed reasons for dead zones in Lake Erie…
Microplastic pollution in the Great Lakes is a fairly new environmental issue, but it is growing rapidly and requires our attention in order to minimize and ultimately stop it. Microplastics are plastic particles in smaller size scales, usually particles less than 5 millimeters in diameter (Eerkes-Medrano et al. 2015). Recent research has documented microplastics in ocean habitats worldwide and specifically in the Laurentian Great Lakes and studies have found that microplastics interact with…
the Upper and Lower Peninsulas. This change comes from rivers and lakes eroding, transporting, and depositing; glaciers carving the land and leaving behind water; and humans manipulating water for beneficial reasons. It’s no secret that Michigan is shaped by water simply due to the fact that it is surrounded by lakes on almost every border it has, but the rivers and lakes have more…
It was intriguing to read “Genocide in the Great Lakes: Which Genocide? Whose Genocide?” because it revealed many critical historical problems, and revelations, between Hutu and Tutsis. When reading history about Rwanda one does not think about actions that are happening outside of the country. It was interesting to find out that many other events were occurring that constituted as genocide, but were never covered by the media. One major historical problem is the fact that peace-makers within…
Management Of Invasive Species In The Great Lakes Basin Thank you for recommending Ohio State Library but I would suggest using google scholar and science direct. I love both of these search engines and with an Ohio State login they are free. Just wanted to say that in case you wanted to let future students about those informational sources. 1 = The site displays a list of invasive animal and plant species in the great lakes basin since the 1800’s. This also describes the steps that the EPA…
Protecting Our Great Lakes Did you know that the Great Lakes provide fresh drinking water for 40 million people (About)? According to the Great Lakes Environmental Research Laboratory (GLERL), the Great Lakes provide 18% of the world’s water supply. The Great Lakes are facing daily threats from industrial pollution, invasive species, extreme climate change, and untreated sewage. If we do not mend these problems soon, this could leave the Great Lakes permanently ravaged. If we don’t act on these…
what the limiting nutrient was in Loughberry Lake, as well as examine the trophic state of the lake. In order to find out what the limiting nutrient was, we performed a few different tests. We began with a secchi disk test to see the transparency of the water. Then, we took water samples that we later used to test the turbidity levels of the water after adding varying amounts of phosphorous and nitrogen. Phosphorous was the limiting nutrient in the lake, because it had the most growth even when…
