The Unintended Benefits Of Dams Should Be Considered Prior To Removal, Jacob Lloyd Jozefowski
The Unintended Benefits Of Dams Should Be Considered Prior To Removal, Jacob Lloyd Jozefowski
Theses and Dissertations
Dams provide multiple benefits; however, they also degrade rivers. Many dams no longer serve their intended purpose and are nearing the end of their operational lives. The aging of dams coupled with the cost of restoration and maintenance, regulation, and the ecologic impacts of dams has resulted in removal becoming a viable management alternative. Despite increased utilization, limited research and a lack of quantitative predictive capacity results in large amounts of uncertainty associated with impacts of dam removal. Additionally, dams which no longer serve their intended purpose may still have unintended positive benefits such as the prevention of the spread …
Sensitivity Of Quagga Mussels (Dreissena Rostriformis Bugensis) To Cyanobacteria At Multiple Life History Stages, Anna Boegehold
Sensitivity Of Quagga Mussels (Dreissena Rostriformis Bugensis) To Cyanobacteria At Multiple Life History Stages, Anna Boegehold
Wayne State University Dissertations
Quagga mussels (Dreissena rostriformis bugensis) originate from brackish waters of the Ponto-Caspian area and are nuisance invasive species in North American and European freshwaters. Their invasion has caused major economic and ecological damages in the Laurentian Great Lakes. Through selective filter feeding, quagga mussels have promoted the growth of cyanobacteria. Harmful cyanobacteria blooms have the potential to produce toxins, which can be toxic to humans and wildlife. Although quagga mussels can increase the prevalence of cyanobacteria blooms, it is unknown how they are physiologically affected by cyanobacteria and understanding these dynamics can be useful in the management of this invasive …
