The invasive freshwater amphipod Dikerogammarus villosus can act as a top predator capable of displacing native amphipods and preying heavily upon a range of native species. Listed as one of The Ponto-Caspian species Dikerogammarus villosus, for instance, spread throughout continental Europe and was recorded for the first time also within Lake Constance in 2003.

Text is available under the 1. Introduction. The killer shrimp Dikerogammarus villosus (Sowinsky, 1894) is an amphipod originating from the Ponto-Caspian region which began its range expansion across European waters in the 20th century after the re-opening of the Rhine-Main-Danube canal (Bij de Vaate et al., 2002).The crustacean is considered a highly invasive and aggressive aquatic species due to its large body, high The invasion of the Ponto-Caspian amphipod Dikerogammarus villosus in European rivers is assumed to reduce macroinvertebrate diversity and to alter ecosystem functions. D. villosus shows an extraordinarily flexible feeding behavior including the ability to use various food sources. On the other hand, its response to predation risk seems to depend on environmental factors.
