Impact ID Scientific Name Impact Type Study Type Study Location Impact Description Geographic Location Reference
4792 Dikerogammarus villosus Competition Observational Field The abundance of indigenous gammarids declined with the increased density of D. villosus in Lake Constance, Germany. The density of D. villosus explained 26% of benthic variability in the lake and thus exhibited a strong impact on the benthic communities Lake Constance, Germany 37168
4799 Dikerogammarus villosus Competition Experimental Laboratory The presence of D. villosus reduced leaf shredding efficiencies of resident Gammrus spp. due to non-consumptive effects (fear responses) 33393
4800 Dikerogammarus villosus Competition Observational Field In the Netherlands, D. villosus has replaced many populations of the European native amphipod species Gammarus duebeni, as well as those of the North American invader G. tigrinus Netherlands 16390
4801 Dikerogammarus villosus Competition Observational Field Replacement of native G. tigrinus by invasive D. villosus was reported in the Lippe River, Germany Lippe River, Germany 37181
4802 Dikerogammarus villosus Competition Observational Field Dikerogammarus villosus has displaced an additional Dikerogammarus invader (D. haemobaphes) in portions of the Danube and Rhine rivers Danube and Rhine rivers 37125
4803 Dikerogammarus villosus Competition Experimental Laboratory The aggressive aggregation and exceptional anti-predatory behaviors of D. villosus forces other gammarids from shelter and often leads to their predation 36809
4804 Dikerogammarus villosus Competition Experimental Laboratory D. villosus displaces Gammarus pulex, G. fossarum, and G. roeselii from shelter which are subsequently consumed by the fishes Neogobius melanostomus and Proterorhinus semilunaris, both of which have invaded the Great Lakers 37162
4805 Dikerogammarus villosus Competition Experimental Laboratory D. villosus displaces Gammarus pulex, G. fossarum, and G. roeselii from shelter which are subsequently consumed by the fishes Neogobius melanostomus and Proterorhinus semilunaris, both of which have invaded the Great Lakers 35449
4806 Dikerogammarus villosus Competition Experimental Laboratory D. villosus displaces Gammarus pulex, G. fossarum, and G. roeselii from shelter which are subsequently consumed by the fishes Neogobius melanostomus and Proterorhinus semilunaris, both of which have invaded the Great Lakers 37164
