Temperature- and Turbidity-Dependent Competitive Interactions Between Invasive Freshwater Mussels.
We develop a staged-structured population model that describes the competitive dynamics of two functionally similar, congeneric invasive species: zebra mussels and quagga mussels. The model assumes that the population survival rates are functions of temperature and turbidity, and that the two species compete for food. The stability analysis of the model yields conditions on net reproductive rat...

15 صفحه اولAssessing the effects of native freshwater mussels on aquatic nitrogen dynamics
Management of the nitrogen cycle has been identified as one of fourteen grand challenges for engineering and is an especially important issue for agricultural watersheds of the Upper Midwest. In large river systems, it has become increasingly important to understand the interactions between abiotic and biotic processes that influence nitrogen cycling. Native freshwater mussels are one of the mo...
متن کاملWhat Makes a Healthy Environment for Native Freshwater Mussels?
Freshwater mussels are mollusks-close relatives of clams, oysters, and saltwater mussels. Many species of freshwater mussels can live for 20 to 30 years, and individuals of some species live for more than 100 years. Freshwater mussels have been valued by humans throughout history. They can produce pearls, and their shells can be used to make buttons for clothing or to serve as seedstock for the...
