“…The analysis of temporal changes in species composition and abundance of amphipods in the littoral zone of the Delta Rhine clearly shows a replacement of native species by non-indigenous ones and changes in the dominance from established non-indigenous species to recent invaders. Similar replacements of native and non-indigenous species by new mass invaders are also observed in the Middle and Upper Rhine (Haas et al 2002;Bernauer and Jansen 2006), in other large rivers in Europe (Dick and Platvoet 2000;MacNeil et al 2004;Jazdzewski et al 2004;Grabowski et al The river Rhine: a global highway for dispersal 2003…”

“…At many sampling sites in the river Rhine a relatively small group of mass invaders dominate in abundance by more than 80% ( Van den Brink et al 1993; Haas et al 2002;Bernauer and Jansen 2006;Bij de Vaate et al 2006;Van Riel et al 2006a;Baur and Schmidlin 2007).

“…Examples of these constraints are intensive navigation and irreversible habitat modification by hydraulic engineering (e.g., canalisation and construction of groynes and stony banks). Improving water quality while these constraints remain in place has led to increased colonization of the river Rhine by non-indigenous species that spread their geographic distribution and caused significant changes in composition, structure and ecosystem processes (Den Hartog et al 1992;Bij de Vaate et al 2002;Haas et al 2002;Van der Velde et al 2006a, b;Bernauer and Jansen 2006;Baur and Schmidlin 2007;Van Riel et al 2006b;Panov et al 2009). …”

The river Rhine is heavily influenced by human activities and suffers from a series of environmental constraints which hamper a complete recovery of biodiversity. These constraints comprise intensive navigation and habitat modification by hydraulic engineering. Improving water quality while these constraints remain in place has led to increased colonization by aquatic invasive species. This tendency has been accelerated by the construction of canals connecting river basins. Over the last two centuries, the total surface area of river catchments connected to the river Rhine via inland waterways has been increased by a factor 21.6. Six principal invasion corridors for aquatic species to the river Rhine are discerned. The extensive network of inland waterways has allowed macroinvertebrate species from different bio-geographical regions to mix, changing communities, affecting the food webs and forming new constraints on the recovery of the native biodiversity. From the eighteenth century onward, in the freshwater sections of the river Rhine, a total of 45 non-indigenous macroinvertebrate species have been recorded. The average number of invasions per decade shows a sharp increase from\1 to 13 species. Currently, the contribution of non-indigenous species to the total species richness of macroinvertebrates in the river Rhine is 11.3%. The Delta Rhine and Upper Rhine exhibit higher numbers of non-indigenous species than other river sections, because the sea ports in the Delta Rhine and the Main-Danube canal function as invasion gateways. Important donor areas are the Ponto-Caspian area and North America (44.4 and 26.7% of the non-indigenous macroinvertebrate species, respectively). Transport via shipping and 123Biol Invasions ( ) 11:1989( -2008( DOI 10.1007 dispersal via man made waterways are the most important dispersal vectors. Intentional and unintentional introductions are highest for the period 1950-1992. The cumulative number of non-indigenous species in time is significantly correlated with the increase in total surface area of other river catchments connected to the river Rhine by means of networks of canals. The species richness of non-indigenous macroinvertebrates is strongly dominated by crustaceans and molluscs. Invasive species often tolerate higher salt content, temperature, organic pollution and current flow than native species. Spatiotemporal analyses of distribution patterns reveal that average and maximum dispersal rates of six invasive species vary between 44-112 and 137-461 km year -1 , respectively. Species arriving in upstream sections first show a shorter time lag between colonisation of the Delta and Upper Rhine than species initially arriving in downstream areas. Temporal analyses of macroinvertebrate assemblages in the littoral zones indicate that native species are displaced by nonindigenous species. However, established non-indigenous species are also displaced by more recent mass invaders.

“…Their ability to reach very high densities means they can have a large impact on benthic communities and even ecosystems (Van der Velde et al 2000, 2006Haas et al 2002;Van Riel et al 2006). Gammaridean amphipods are considered to be detritivores (phyto-detritophages, detritophages), omnivores (phyto-zoophages, zoophytophages) or predators (zoophages) (Monakov 2003).…”

“…Marguillier et al (1998) and Van der Velde et al (2000) noticed that the Ponto-Caspian gammaridean species D. villosus, which has invaded the Rhine system since 1994/1995 through the MainDanube canal (Bij de Vaate et al 2002), must act as a predator, in view of the high values of d 15 N, which are similar to those measured in zoobenthivorous fish. Van der Velde et al (2000 and Haas et al (2002) noticed that the composition of the communities changed after the arrival of D. villosus, and densities of macroinvertebrates, including the nonindigenous G. tigrinus on the stones along the River Rhine, were also observed to decrease (Van Riel et al 2006, 2009Leuven et al 2009). Dick and Platvoet (2000) noticed the disappearance of the native Gammarus duebeni along the stony shores of Lake IJsselmeer, as well as a decrease in G. tigrinus in this zone after the arrival of D. villosus (Platvoet et al 2009a).…”

Environmental and morphological factors influencing predatory behaviour by invasive non-indigenous gammaridean species

et al. 2009

Predatory behaviour seems to be more frequent in invasive gammaridean species than in native ones. This results in the exclusion of other, mostly native gammaridean species and a change in benthic communities. The present study analysed the influence of environmental factors (water temperature) and morphological factors (sex, body parts involved in catching and holding prey) on the predatory behaviour of Dikerogammarus villosus. A diet study of invasive relatives of D. villosus showed that predation intensity is especially high in spring and summer, that is, at increasing and high temperatures. Experiments with D. villosus in climate rooms at various temperatures, using the native Gammarus fossarum as prey, showed that the average predation rate by both sexes gradually increased over the temperature range from 5 to 30°C. Natural mortality during the experiments was negligible compared to losses due to predation. At each temperature, the predation rate by females was lower than that by males. Males showed a steep allometric growth of body parts involved in the process of catching and holding prey, compared to females at increasing body size in a number of measurements. This may explain the difference in predatory behaviour between males and females, which plays a role in intraguild predation a supposed mechanism for species displacement.

1. Non-native species introductions are a major concern for the conservation of natural ecosystems. The spread of non-native species depends not only on their adaptation to the new environment, but also on the biotic features of the nonnative and resident native species and their environment that determine competition in natural habitats.2. There is little empirical evidence from field studies that demonstrates the existence of competition between the non-native clam Corbicula fluminea and native freshwater mussels, and even less evidence on how global warming might affect competition and re-shape ecological communities.3. In this study, field surveys within the biogeographic Atlantic region in the north west of the Iberian Peninsula found little spatial overlap between C. fluminea and the native freshwater mussel Unio delphinus.4. In the laboratory, intraspecific and interspecific competition between these freshwater bivalves was assessed through physiological parameters and nutritional condition in a global warming context. A significant effect for the physiological parameters and nutritional condition ofintraspecific competition was found in C. fluminea, whereas asymmetric competition was evidenced between both species at greater densities of C. fluminea.6. Under simulated heat wave conditions, the non-native C. fluminea was competitively superior to the native freshwater mussels when both occur together. 7. Present findings suggest that further population declines of freshwater mussels in the Iberian Peninsula are expected under conditions of global warming, owing to competition with C. fluminea.
