Special issue on Behaviour and Aquatic Invasions is now online!
Editors: Kit Magellan, Mhairi Alexander, Amy Deacon and Marian Wong.

Welcome to the Special Issue of Aquatic Invasions titled ‘Behaviour and Aquatic Invasions in the 21st Century: Progress, Trends and Future Research’.

In this issue, we focus on how animal behavior is central to biological invasions in aquatic ecosystems, highlight how much this field has progressed in the past 20 years, and show how consideration of animal behavior can aid management of aquatic invasive species.

In this issue:

Snail-blazers: Invasive New Zealand mud snails (Potamopyrgus antipodarum) in the US float up and attach themselves to the water surface even with unknown native predators, which may aid their survival and dispersal.

Anuran attacks: Invasive African clawed frog (Xenopus laevis) in France respond to native predators regardless of the degree of relatedness to home-range predators, while American bullfrog, Lithobates catesbeianus, tadpoles in Korea show behavioural plasticity by increasing their refuge use in response to simulated predator attack. Native frogs learn to avoid invasive and toxic cane toad (Rhinella marina) tadpoles, which continues as an aversion to more toxic metamorph toads.

Being social can be deadly: Asocial mosquitofish (Gambusia affinis) are more likely to survive predation than social fish.

Food for thought: Guppies (Poecilia reticulate) are often introduced for mosquito control but their preference for mosquito larvae prey depends on their social and physical environment, while swimming with others can reduce foraging efficiency of native species and therefore reduce native fitness.

Hot topic: Climate change is likely to increase the invasive success of mosquitofish (Gambusia affinis) and induce a competitive reversal in a native-invasive crayfish pair

Behaviour and management: A greater understanding of how individual differences in sea lamprey (Petromyzon marinus) behavior influence trapping could help improve the management of invasive species

Book review: Insights into behavior and aquatic invasions drawn from a recent book "Biological Invasions and Animal Behaviour"
