Interspecific differences in drift behaviour between the native Gammarus pulex and the exotic Gammarus roeseli and possible implications for the invader’s success

Abstract

“Drifting” is known to subject aquatic invertebrates to intense predation by drift feeding fish. Consequently, interspecific variations in drifting behaviour could lead to differences in predation pressure between coexisting prey species. Predation being an important factor determining the success of invaders, differences in drift patterns could advantage… (More)
