摘要：

Summary: "Nonindigenous species are having a dramatic effect on marine, estuarine and freshwater ecosystems throughout the world. These invading species can have strong economic and environmental consequences. The impacts of the recent and well documented zebra mussel invasion in North America, ranging from clogged municipal and industrial water intake pipes to declines and perhaps extinction of native mussel populations, is testimony to this fact. Unless adequate precautions are taken, nonindigenous species invasions of Chesapeake Bay and other estuaries will continue to occur, causing a broad range of impacts."
