Aquatic Invasions is an open access, peer-reviewed international journal focusing on biological invasions in both inland and coastal water ecosystems from around the world. It was established in 2006 as initiative of the International Society of Limnology (SIL) Working Group on Aquatic Invasive Species (WGAIS) with start-up funding from the European Commission Sixth Framework Programme for Research and Technological Development Integrated Project ALARM. Aquatic Invasions provides a forum for professionals involved in research of aquatic invasive species, including a focus on the following: • Advances in species identification • Patterns of species dispersal, including range extensions with global change • Population dynamics • Ecological and evolutionary impacts • Prediction of new invasions.
