Special Issue: Behaviour in aquatic invasions.
This special issue shows how much the field of behaviour and invasions has evolved over the last 20 years. The 11 papers presented here cover behavioural topics ranging from predator-prey interactions through competition to learning, and focus on fish, amphibian and invertebrate model species. However, perhaps the most striking pattern is geographical. The research for this special issue, together with the invasive model species, encompasses both Northern and Southern hemispheres and spans six continents from Asia to the Americas, with mostly multinational author teams. Behaviour and invasions is a truly global field of research.
