Selective predation by fish: a further reason for the decline of native gammarids in the presence of invasives?

Selective predation by fish: a further reason for the decline of native gammarids in the presence of invasives?

Predation by fish (rainbow trout and perch) on the invasive gammarids Dikerogammarus villosus and Echinogammarus ischnus and the natives Gammarus fossarum, Gammarus roeseli and Gammarus pulex was investigated under different substrate conditions (gravel, large stones, fine sand) in laboratory experi...
