Biological Invasions publishes research and synthesis papers on patterns and processes of biological invasions in terrestrial, freshwater, and marine (including brackish) ecosystems. Also of interest are scholarly papers on management and policy issues as they relate to conservation programs and the global amelioration or control of invasions. The journal will consider proposals for special issues resulting from conferences or workshops on invasions. The Editor-in-Chief is Daniel Simberloff, University of Tennessee, USA. We are pleased to announce that Biological Invasions is now available Online First. The Online First service lets users access peer reviewed articles well before print publication. These articles are searchable and citeable by their DOI (Digital Object Identifier) and hence significantly reduce the time it takes for critical discoveries to reach the research community.
