TLDR
In freshwaters in The Netherlands, it is shown that the invasive Ponto–Caspian crustacean amphipod Dikerogammarus villosus is rapidly eliminating Gammarus duebeni, a native European Amphipod, andGammarus tigrinus, until now a spectacularly successful invader from North America.
Predatory impact of the freshwater invader Dikerogammarus villosus (Crustacea : Amphipoda)
TLDR
Dikerogammarus villosus predatory behaviour included shredding of prey and infliction of "bite" injuries on multiple victims, and killed significantly greater numbers of macroinvertebrate taxa, trophic groups, and body sizes.
Drastic changes in the amphipod fauna (Crustacea) of Dutch inland waters during the last 25 years
TLDR
Electrophoretic tests give evidence that a second invasion of Gammarus tigrinus, this time from Germany, is taking place.
No genetic bottleneck or associated microparasite loss in invasive populations of a freshwater amphipod
TLDR
The data suggest that D. villosus invasion was either massive, or recurrent, or both, allowing a parasitic cortege to follow the host, and the maintenance of genetic diversity may have contributed to its success, including the variation in resistance in the face of the natural enemies.
Flexible omnivory in dikerogammarus villosus (Sowinsky, 1894) (Amphipoda) - amphipod pilot species project (ampis) report 5
TLDR
The very flexible feeding modes of D. villosus, which make diet switches possible, form a trait that must be an important factor in the invasion success of this Ponto-Caspian gammaridean species, and may thus explain for a great deal its high ecosystem impact.
The Ponto-Caspian ‘killer shrimp’, Dikerogammarus villosus (Sowinsky, 1894), invades the British Isles
The Ponto-Caspian amphipod Dikerogammarus villosus was found both in the margins and open water areas of Grafham Water, a large reservoir in Cambridgeshire, U.K., in September 2010. Both adults and
Direct and indirect effects of species displacements: an invading freshwater amphipod can disrupt leaf-litter processing and shredder efficiency
TLDR
Investigation of shredders and leaf-litter processing in water bodies invaded by the highly predatory Ponto-Caspian amphipod Dikerogammarus villosus found the shredding efficiency of surviving amphipods and isopods declined significantly, indicating that predator-avoidance behavior may override leaf processing.
Intraguild predation and species exclusions in amphipods: the interaction of behaviour, physiology and environment.
TLDR
A novel interaction among intraguild predation, physiological adaptation and environment may explain the complex distributions of two putatively competing aquatic amphipods and ‘switches’ in species dominance that are determined by the relative values of reproductive rate and mutual predation are generated.
Invader–invader interactions in relation to environmental heterogeneity leads to zonation of two invasive amphipods, Dikerogammarus villosus (Sowinsky) and Gammarus tigrinus Sexton: amphipod pilot
TLDR
This study examines habitat use and its mediation of the predatory interaction between invasive aquatic amphipods, the Ponto-Caspian Dikerogammarus villosus and the N. American Gammarus tigrinus, and shows that both species utilize crevices, different sized holes in a plastic grid, non-randomly.
First record of a cavernicolous atyid decapod Crustacean in the Iberian Peninsul, new perspectives on the evolution of the genus Typhlatya miravetensis n.sp.
TLDR
A new model based on vicariance principles that involves further evolution of each species after the disruption of the ancestral range is developed, which allows new estimations for the age and evolution of the genus Typhlatya.
