We are inviting expressions of interest for an upcoming Special Issue of Aquatic Invasions (http://www.aquaticinvasions.net) focusing on Behaviour in Aquatic Invasions. We will consider manuscripts focusing on the behaviour of invasive species and/or native species that are affected by invasives. The deadline for submissions will be around September 2018 with a prospective publication date towards the end of 2019. Please contact Kit Magellan (Editor in Chief: Aquatic Invasions) at kit.magellan@invasivesnet.net with a tentative title or general subject area if you are interested in contributing to this Special Issue.
