Abstract

First record of the Ponto-Caspian amphipod Echinogammarus trichiatus (Martynov, 1932) (=Chaetogammarus trichiatus) (Crustacea: Amphipoda) for the Middle-Danube (Slovakia and Hungary).

Abstract

The invasive Ponto-Caspian amphipod Echinogammarus trichiatus (formerly known as Chaetogammarus trichiatus) is reported for the first time in Slovakia (22 August 2007, near Bratislava) and in Hungary (15 September 2009, near Rajka). This range expansion is probably a result of a recent downstream spread of the Upper-Danubian population. Our records indicate that the species can inhabit artificial rip-raps as well as near-natural gravel banks, and co-occurs with its relatives already present. Suitable habitats can be found all along the Middle-Danube, so further spread of the species is anticipated.
