Zebra mussel

of Dreissena polymorpha on native mussels within the Great Lakes region The Great Lakes area once supported an abundant number of freshwater mussels (Mollusca: Unionacea). The invasion of Zebra mussels (Dreissena polymorpha) has decimated these populations, by outcompeting native mussels in dispersal rates, and reproduction, due to enhanced survival mechanisms. Understanding the mechanisms that have allowed Zebra mussels to out complete native fresh water mussels, will provide insight into…

is much worse than the zebra mussels. Zebra mussels are small freshwater mollusks. Garlic mustard has a negative impact on the environment because of many things. For starters, it is easily spread. Not only is it spread easily, but it is incredibly hard to get rid of. Garlic mustard spreads without difficulty and it is already hard to get rid of, so it is just overall a terrible thing for the environment. It is worse for the environment than zebra mussel because zebra mussels help fishermen by…

economically and environmentally. One example of an invasive species is the zebra mussel. In this essay you will learn what the zebra mussel is, why we don’t want it in Iowa, and how this invasive species is being controlled. The zebra mussel is a freshwater mollusc. It is the size of a fingernail, but can grow up to two inches. Zebra mussels get their name from the striped pattern that appears on them. The zebra mussel has a D-shaped shell. It was introduced to the Great Lakes from the ballast…

know that there are over 380 non-native species in the Great Smoky Mountains? Non-native species are really harmful because they can severely damage the environment. This can be seen with the rabbit population in New Zealand, the Kudzu plant, and zebra mussels. First of all, the rabbit population is out of control in New Zealand. First of all, rabbits were brought to New Zealand in the 1700s and 1800s by European sailors. They thought they would hunt the rabbits for food. However, the rabbits…

room and started reading and taking notes. Considered one of most damaging of the invasive species introduced to this country, zebra mussels were transported to the Great Lakes in ballast water from a transoceanic vessel, originally found in Russia… The most interesting fact he found was that It is almost impossible to stop them from reproducing, as female zebra mussels can produce 100,000 to 500,000 eggs per year. They stick to hard surfaces and eat algae which is fish food. And without food…

Sometimes drastic measures need to be taken to prevent an even more drastic situation, and that is the dilemma today's scientists are facing on the topic of the Alewife, a small silver fish who have wreaked havoc on freshwater ecosystems across Ontario. The invasive species were first spotted in Lake Ontario in 1873, having been carried over in the ballast water of ships. They quickly reproduced in those bodies of water, then bypassed Niagara Falls through the Welland Canal By 1960, they had…

lakes and waterways. Many others “hitchhike” on watercraft, bait buckers, and other recreational gear from one habitat to another. One such known hitchhiker is the zebra mussel, given the scientific name Dreissena polymorpha. Recently, Mallard Lake became the fourth body of water in the county to have a confirmed case of zebra mussel infestation, and there are thousands more streams, rivers, and lakes in the surrounding area with the same issue. This species’ particular invasion is becoming an…

killing the fish. Sea Lamprey kill more lake trout than all fishing for lake trout combined. Zebra Mussels are also a big problem in the great lakes. They are a threat to the food web because they eat what the native fish rely on for food. The Zebra Mussels arrived at the great lakes from boats that traveled through the Atlantic Ocean and went through the canals which lead to the Great Lakes. Zebra Mussels accumulate toxins 300,000 times higher than the concentration in the lake. The Asian Carp…

The Great Lakes hold 21% of our natural freshwater supply. I am a limnologist living in Detroit, Michigan. My city is located near Lake Erie and I visit it weekly with my research team to record the changes in the lakes. I've written two books: one about Lake Erie and the other about Lake Huron. Many believe that The Great Lakes are dying; as an expert and an experienced scientist, I can confirm that this is true mostly because of pollution, habitat loss, and non-native species entering the…

great lakes region. Journal of Great Lakes Research, 42(3), 703–707. doi:10.1016/j.jglr.2016.03.016 4 = This reading tells about the lack of research being done to understand the interactions between mussels and crayfish. They explain both positive and negative outcomes that came from invasive mussels in regards to indigenous species food supply. This can help to set the priorities of different management plan to help in the fight to stop invasive species.…
