| Impact Description | The competitive displacement of Gammarus fasciatus by Echinogammarus ischnus is mediated more by abiotic factors than by co-occurring exotic predator, the round goby. There was no difference between the two species in their vulnerability to predation on dreissenid-covered substrate, which contrasts with other similar studies. |
