    Mathematician develops model to control spread of aquatic invasive species

    Credit: University of Tennessee Adjusting the water flow rate in a river can prevent invasive species from moving upstream and expanding their range. An applied mathematician at UT has developed a partial differential equation model to find the desired flow rate to reduce invasive populations. The model is detailed in a new paper by Suzanne…

    Washington state to use dog to detect invasive mussels on boats

    This photo provided by the U.S. Department of Agriculture shows a group of zebra mussels. Government officials are cracking down on ships that allow in invasive species. (Anonymous/The Associated Press) Quagga and zebra mussels siphon in water to pluck out microscopic organisms that can throw food chains out of balance, and their sheer numbers in…
