“…Chemical detection in amphipods is mediated mainly via specific sensillae located on the antennae (Hallberg & Skog 2011) and is used in mate choice and species discrimination, reducing the chances of interspecific mating between similar species (Dick and Elwood 1990 (Cothran et al 2013; Dick & Elwood 1990). Chemical cues are also used by females to recognize and defend their offspring against conspecifics (Mattson & Cedhagen 1989), and some amphipods can also recognize alarm cues from damaged conspecifics and mount a strong freezing response as an anti-predatory strategy (Sehr & Gall 2016). Killer shrimp have been reported to use chemical cues to recognize and avoid potential predators such as the spiny-cheek crayfish Orconectes limosus (Hesselschwerdt et al 2009), the European bullhead Cottus gobio (Sornom et al 2012) and the racer goby Babka gymnotrachelus (Jermacz et al 2017), and our study shows they can also use chemical cues to find zebra mussels that provide not only cover and refuge, as seen in our study and other studies (Ricciardi et al 1997), but also food through the production of faeces and pseudo faeces (Gergs & Rothhaupt 2008a; Gergs & Rothhaupt 2008b; Ricciardi et al 1997; Stewart et al 1998a).…”

Invasion facilitation, whereby one species has a positive effect on the establishment of another species, could help explain the rapid colonisation shown by some freshwater invasive species, but the underlying mechanisms remain unclear. We employed two-choice test arenas to test whether the presence of zebra mussel (Dreissena polymorpha) could facilitate the establishment of the killer shrimp (Dikerogammarus villosus). Killer shrimp preferred to settle on mats of zebra mussel, but this was unrelated to mat size, and was not different from attraction shown to artificial grass, suggesting that zebra mussel primarily provides substrate and refuge to the killer shrimp. Killer shrimp were strongly attracted to water scented by zebra mussel, but not to water scented by fish. Chemical attraction to the zebra mussel’s scent did not differ between sympatric and allopatric populations of killer shrimp, suggesting that chemical facilitation is not an acquired or learned trait. Our results have implications for managing the spread of killer shrimp, and perhaps other freshwater invasive species, because invasion facilitation could significantly increase establishment success. Failure to consider invasion facilitation may underestimate the risk of establishment and likely impact of some aquatic invaders.

Chemical attraction to the zebra mussel's scent did not differ between sympatric and allopatric populations of killer shrimp, suggesting that chemical attraction is not an acquired or learned trait. Our study shows, for the first time, chemical attraction between two highly invasive freshwater species, thereby providing a plausible mechanism for invasion facilitation. This has implications for managing the spread of killer shrimp, and perhaps other freshwater invasive species, because chemical attraction could significantly increase establishment success in mutualistic systems. Failure to consider invasion facilitation may underestimate the risk of establishment, and likely also the impact of some aquatic invaders.
