“…However, some more recent studies of the macroinvertebrate communities of Croatian and Serbian section of Danube failed to detect its presence in the Danube (Paunović et al 2007), while other studies report its presence in the Serbian part of Danube (Paunović et al, 2010). However, in the most recent study Borza et al (2015) reported findings of the species in the Croatian section of the Danube. Based on these and our data we assume that E. ischnus was more abundant in the Danube in the past, while now has low abundance and it is therefore difficult to detect.…”

“…Based on these and our data we assume that E. ischnus was more abundant in the Danube in the past, while now has low abundance and it is therefore difficult to detect. It is possible that Dikerogammarus villosus and Chelicorophium curvispinum, which are now the dominant amphipods in the Danube (Žganec et al, 2009;Borza et al, 2015), have caused the decline of E. ischnus. The decline of E. ischnus observed in the lower Rhine was probably facilitated by the mass abundance of C. curvispinum, which probably reduced the colonization success of E. ischnus, a lithophilic dweller, by covering the solid substrates in the river with mud tubes (Bij De Vaate et al, 2002).…”

The Ponto-Caspian alien and invasive amphipod, Echinogammarus ischnus (Stebbing, 1899), was found in Croatia at three sites in the lower course of the Drava River and at three sites in the Danube River (Batina, Borovo and Ilok). The most upstream site in the Drava where the species was found is a locality near Donji Miholjac, approximately 82 km upstream from the confluence with the Danube River. At this site as well as at two downstream sites (Osijek and Belišće) in Drava it was found together with the dominant invasive amphipods Dikerogammarus villosus and Chelicorophium curvispinum, while at the Donji Miholjac site it also co-occurs with two native species, Gammarus fossarum and G. roeseli. Ponto-kaspijski strani i invazivni rakušac Echinogammarus ischnus (Stebbing, 1899), pronađen je u Hrvatskoj u donjem toku rijeke Drave i na tri lokaliteta u Dunavu (Batina, Borovo i Ilok). Najuzvodnija postaja na kojoj je nađen u Dravi, kod mjesta Donji Miholjac, udaljena je otprilike 82 km od ušća u Dunav. Na toj, kao i na dvije nizvodne postaje (Osijek i Belišće) u Dravi, zabilježen je zajedno s druge dvije invazivne vrste rakušaca Dikerogammarus villosus i Chelicorophium curvispinum, dok na postaji kod Donjeg Miholjca uz ove dvije dominantne strane vrste dolazi zajedno s još dvije autohtone vrste Gammarus fossarum i G. roeseli.

“…Mysids were excluded, as their habitat use markedly differs from that of D. villosus (epibenthic or semi‐pelagic). In addition, they mostly reach high abundances in semi‐enclosed inlets and slow‐flowing sidearms, so they were found only sporadically during the survey (Borza et al, ). The filter feeding, tube‐dwelling corophiids were excluded, too, as the data suggest that their abundance is primarily determined by the quality and quantity of suspended matter, rather than by habitat characteristics (Borza, Huber, Leitner, Remund, & Graf, ).…”

“…The species locally eliminated by D. villosus are all native to Europe (e.g. Gammarus spp., Asellus aquaticus (Linnaeus, 1758); Borza et al, ; Dick & Platvoet, ) or are North American invaders to Europe (e.g. Gammarus tigrinus Sexton, 1939; Dick & Platvoet, ; Leuven et al, ); nevertheless, some species were able to persist in the invaded waters by switching habitats (Hesselschwerdt, Necker, & Wantzen, ; Platvoet, Dick, MacNeil, van Riel, & van der Velde, ).…”

Studying interactions among co‐evolved invaders might help us in understanding, predicting, and perhaps mitigating the impact of the invading species on the native biota. The factors of spatial niche differentiation were investigated among invasive Ponto‐Caspian peracarids with the aim of revealing how co‐evolved species can coexist with the ‘killer shrimp’ Dikerogammarus villosus, an invasive gammarid replacing non‐Ponto‐Caspian species throughout Europe. Multi‐habitat samples from the third Joint Danube Survey were analysed by partitioning the variation in species density data between environmental and spatial explanatory variable sets. Relevant predictors were identified by forward selection and their role was interpreted based on the redundancy analysis (RDA) triplot. The effect of substrate types was further analysed in certain species using generalized linear models. The analysis revealed characteristic differences in habitat preference (i.e. spatial niche differentiation) among the species, allowing coexistence with D. villosus at different spatial scales. The relatively small and lean body of Chaetogammarus ischnus and Jaera sarsi might allow the avoidance of interference with large Dikerogammarus specimens by using narrow interstices among pebbles and stones (microhabitat‐scale differentiation). The remaining Ponto‐Caspian species included in the analysis showed an affinity for substrate types (Obesogammarus obesus) or current velocity intervals (Dikerogammarus bispinosus) that differed from those preferred by D. villosus (mesohabitat‐scale differentiation), presumably in connection with feeding preferences in some cases (Dikerogammarus haemobaphes and Trichogammarus trichiatus). These results provide a framework for a preliminary risk assessment concerning the continuing high potential for range expansion of D. villosus: i.e. the identification of the most vulnerable species in those regions of the world not invaded at present but potentially colonizable, based on their habitat preference and morphology. The lessons learned from Ponto‐Caspian peracarids can be applied to the whole macroinvertebrate fauna, as the same principles (i.e. the avoidance of interference) can be expected to determine their coexistence with D. villosus.

“…The severe ecological impacts of alien species dispersal in the Danube River was already elucidated by the Joint Danube Survey 2 (ICPDR, ), as among the 10 most frequent macroinvertebrate species, nine are considered as alien (Graf et al, ). The Joint Danube Survey 3 (ICPDR, ) confirmed these findings (Borza et al, ). Benthic assemblages of the Danube River are nowadays dominated by nonindigenous, invasive, or cosmopolitan species (Graf, Csányi, et al, ; Graf, Leitner, & Pletterbauer, ).…”

For centuries, rivers have experienced massive changes of their hydromorphic structures due to human activities. The Danube River, the second largest river in Europe, is a case in point for longterm societal imprint. Resulting human-induced pressures are a key issue for river management, aiming to improve the ecological conditions and guarantee the provision of ecosystem services.As the most international river basin in the world, the management of the Danube is particularly challenging and needs a well-organized cooperation of 19 nations. The recent river basin management plan has identified pollution and hydromorphological alterations as most pressing problems, but it has also acknowledged newly emerging issues.
