This exciting issue of Aquatic Invasions reveals some secrets of successful invaders and studies the occurrence and impacts on native species in different aquatic environments.
What makes the Asian leech (Barbronia weberi) a successful invader? Uniparental reproduction resulting in thousands of offspring in one year!
The ability of freshwater carp (Carassius gibelio) to reproduce both unisexually and bisexually increases its ability to colonize various habitats in northern Europe and Asia.
The gammaridean amphipod (Grandidierella japonica) was reported for the first time in north-eastern United States, where it has now established in Casco Bay, Maine and Long Island Sound, Connecticut. The authors present evidence that the two populations are the result of separate invasions.
How do introduced species impacts native species communities? Nour et al. looked at the population structure of the recent invader Hemigrapsus takanoi and prey size selection on Baltic Sea mussels.
Carbonell et al. conducted an experimental test of interspecific competition between the alien boatman Trichocorixa verticalis and the native corixid Sigara lateralis.
Sfriso et al. present an interesting conundrum in their paper on invasion of alien macroalgae in the Venice Lagoon, a pest or a resource?
Ferrario et al. explored marine fouling communities in artificial and natural habitats and found that species resistance was strongly affected by chemical but not by physical disturbances.
Last but not least, Staehr et al. report on three decades of non-indigenous species (NIS) monitoring data from Denmark, showing that the number of known NIS more than doubled.
