摘要：During a survey of the Belarusian part of the Dnieper River conducted on 19-22 July 2006, we revealed five invasive Ponto-Caspian amphipod species in its benthos community: Chaetogammarus ischnus , Chelicorophium curvispinum , Dikerogammarus haemobaphes , Dikerogammarus villosus and Pontogammarus robustoides . All of them except C. curvispinum are reported in Belarus for the first time. The number of alien amphipod species and their abundance were found to decrease gradually in the upper sections of the river.
