Mussel

Purpose This paper will discuss the Great Lakes regions issue with invasive species introduced via ships ballast water, and the response that has followed since then. The impact of shipping and its economic benefit to the region will also be reviewed. The Great Lakes The great lakes system consists of a group of linked freshwater lakes spanning across the traditionally defined “heart land” region of North America. The system consists primarily of 5 distinct bodies of water; Lake Superior,…

IN STARFISH POPULATION WILL RESULT IN A DRAMATIC INCREASE IN MUSSEL POPULATION was supported by my data. I started with an amount of 60 Starfish in my tidal pool. The results of this scenario was that the average amount of Mussel population was 99 at 60 Starfish. As we went down the line in the number of Starfish present in the start of the experiment the number of Mussel population increased. With the amount of 20 Starfish, the Mussel population averaged at 202.67- over double as much as with…

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…

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…

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 didn’t…

The rayed bean mussel is a small, freshwater mussel, usually less than 1.5 inches long. Federally listed as endangered in 2012 (77 FR 8632 8665, March 15, 2012), its historical range in North American included 115 streams and lakes; however, current populations are only found in 31…

of a keystone predator and often utilized by textbooks to illustrate the concept. Sea Otters “Enhydra Lutris” are involved in maintaining the population of macrobenthic grazers such as sea urchins “Strongylocentrotus polyacanthus” and mussels. Sea urchins and mussels are the dominant species in these shallow water benthic ecosystems. Left unchecked, the sea urchins overgraze the benthic vegetation and the kelp forests. Kelp forests provide habitat for fish including “Irish lords Hemilepidotus…

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.…
