A geographic footprint of boaters entering & departing Lake Powell: Aquatic nuisance species management: Potential distribution of the invasive zebra/quagga mussel into south western United States.
This book summarizes all currently available information on the ecology, environmental impacts and control methods of the golden mussel in industrial plants. The golden mussel was introduced in Hong Kong, Taiwan, Japan, and South America between 1965 and 1990, swiftly spreading in freshwater waterbodies. In most areas invaded it has become the dominant macroinverebrate and a major fouling pest of industrial plants. Limnoperna fortunei attaches to any hard surface, as well as to some less firm substrates. The growth of Limnoperna populations in raw cooling water conduits became a common nuisance in many industrial and power plants that use raw river or lake water for their processes, both in South America and in Asia. This work is written by experts on the golden mussel from Asia, Europe, North America and South America, each chapter critically reviews previously available information, which is in sources of limited distribution, such as internal reports and theses, in various languages.
Humans play a critical role in the dispersal of exotic invasive species. Estimating pathways for non-native species by human vectors is a major challenge to invasion biologists, as well as federal, state and regional resource managers. Focusing on dispersal pathways that are available to not just one, but a number of species, allows for the efficient inspection and possible reduction of many exotic species introductions. Transient recreational boating has been used as an estimate of invasion pressure to inland freshwater bodies, and used to predict prior and future species invasions. Specifically, recreational boating traffic is used to predict human-mediated aquatic invasion in the Midwestern United States through the use of spatial interaction models called gravity models. California and Nevada contain some of the largest and most recreationally utilized lakes, rivers and reservoirs in the Western United States. These waterways attract millions of visitor days by boaters not only from within the region, but all over the United States and are currently experiencing increasing numbers of non-native species introductions from the Midwestern U.S.
The St. Lawrence Seaway was considered one of the world's greatest engineering achievements when it opened in 1959. The $1 billion project-a series of locks, canals, and dams that tamed the ferocious St. Lawrence River-opened the Great Lakes to the global shipping industry. Linking ports on lakes Superior, Michigan, Huron, Erie, and Ontario to shipping hubs on the world's seven seas increased global trade in the Great Lakes region. But it came at an extraordinarily high price. Foreign species that immigrated into the lakes in ocean freighters' ballast water tanks unleashed a biological shift that reconfigured the world's largest freshwater ecosystems. Pandora's Locks is the story of politicians and engineers who, driven by hubris and handicapped by ignorance, demanded that the Seaway be built at any cost. It is the tragic tale of government agencies that could have prevented ocean freighters from laying waste to the Great Lakes ecosystems, but failed to act until it was too late. Blending science with compelling personal accounts, this book is the first comprehensive account of how inviting transoceanic freighters into North America's freshwater seas transformed these wondrous lakes.
