Quagga mussel

zebra mussel Dreissena polymorpha has made its way to the top of the list as one of the most destructive invasive species in the North American water systems. While many studies have been made focusing on the ecological impact of zebra mussels, little is known about the geographical history of their invasions and patterns of genetic differentiation among and within populations in their native and invaded ranges (May, Gelembiuk, Panov, Orlova, & Lee, 2006). From what is known, zebra mussels were…

The great lakes have experienced a rise in the number of harmful Alga blooms (NOAA, n.d.). Quagga and zebra increase the amount of sunlight penetrating at the bottom of the lake which promotes this growth (NOAA, n.d.). Cladophora is responsible for one particular alga bloom which grows at the bottom of the lake (NOAA, n.d.). Large piles of Cladophora can be found washed up on the shores of beaches after it dies (NOAA, n.d.). Harmful bacteria are trapped within these piles which can harm humans…

them. Mussel shells consist of mainly calcium carbonate. To eat, mussels suck in water through their gills. The water brings oxygen and food into the mussel. Food is separated and taken to the palps then into the mouth. In females, gills also serve as an incubation chamber for baby mussels. Mussels also have a circulatory system powered by a two-chambered heart and a digestive system including: a stomach, intestines, and an anus. A nervous system consisting of ganglia controls the mussels’ body…

The most exceedingly bad offenders — alewives, ocean lampreys and zebra and quagga mussels — have demolished sustenance networks. Egan devotes 33% of the book to these intruders and scholars' ideal, and some of the time misinformed, endeavors to contain them. However, the lakes additionally confront lesser-known issues. Egan deftly…

Complex issues such as health problems, environmental issues, or environmental health problems, such as air and water pollution, hazard wastes sites, lead poisoning and species instability are all liked together and are fixed in communities in which they occur. These kinds of complex problems that occur in communities are said to be “wicked problems” where different stakeholders cannot find scientific solutions in order to fix these complex issues. These problems are seen throughout the world,…

Everybody loves the big city of Chicago, and knows that our drinking water comes from Lake Michigan. Well, imagine that water being filled with sewage and chemicals. That's the way that Lake Michigan used to be, and thanks to reversing the river, we will never have that problem again. A closer study of this historical event will illustrate how the workers completed this impossible sounding task, what impact this had on the Chicago people, and how reversing the river may have created more…
