Abstract
The U.S. Geological Survey’s Nonindigenous Aquatic Species (NAS) Database has tracked introductions of freshwater aquatic organisms in the United States for the past four decades. A website provides access to occurrence reports, distribution maps, and fact sheets for more than 1,000 species. The site also includes an on-line reporting system and an alert system for new occurrences. We provide an historical overview of the database, a description of its current capabilities and functionality, and a basic characterization of the data contained within the database.
Highlights
The overarching aim of this Special Issue of Management of Biological Invasions is to describe such information systems
Particular focus has been given to documenting the various approaches for collection, harmonization and integration of information; discussing related technical issues and developments, including data publishing; providing examples of collaboration of information systems through networking and interoperable web services; discussing sustainability and funding issues; prioritizing future efforts through horizon scanning; and assisting the publication of large datasets related to the information systems, as citable online supplementary material
This Special Issue is not inclusive of all information systems that focus on biological invasions, but it does present a number of international, regional, national and local initiatives
