“…The studied species can inhabit waters of much higher salinity than those tested in our study, up to 6 PSU (Dobrzycka-Krahel & Surowiec, 2011;Dobrzycka-Krahel et al, 2015), which roughly corresponds to 12000 lS/cm (Wagner et al, 2006). Pontogammarus robustoides has greater salinity resistance, surviving even in fully saline water of 34 PSU (Santagata et al, 2008) than D. villosus tolerating up to 20 PSU (Bruijs et al, 2001). This difference between the species may explain the affinity of D. villosus for lower conductivity in our experiment.…”

Abiotic factors affecting habitat selection by two invasive gammarids Dikerogammarus villosus and Pontogammarus robustoides

Identification of habitat preferences of invasive organisms is crucial for predicting their distribution and impact. We conducted laboratory experiments to determine preferences of Dikerogammarus villosus and Pontogammarus robustoides, invasive in Europe, with regard to ionic content (450 and 830 lS/cm in a Y-maze), flow (0-30 cm/s in a flow-through tank with stagnant water refuges) and temperature (a gradient 5-35°C). D. villosus selected the lower salinity, whereas P. robustoides did not discriminate between salinities, suggesting that, the raised ionic content in large European rivers cannot explain their absence in small tributaries, as previously postulated. Gammarids never preferred flowing over stagnant water, but could stay in a flow B10 cm/s without behavioural changes. They avoided flow C15 cm/s. Gammarids selected warmer water than their acclimation temperatures. Temperature selection by D. villosus was related to its acclimation temperature. The choice of P. robustoides depended on the season: it preferred a lower temperature in summer than in autumn. Therefore, its thermal preferences were more stable throughout the year, which might be advantageous in shallow, thermally variable areas. Gammarids used environmental variables to select warm, lentic, freshwater locations, which may help them locate an optimum microhabitat and thrive in temporally and spatially variable environments.

“…Although D. villosus is considered as salt tolerant, some native freshwater species such as E. berilloni are also able to survive at similar salinities (28.3 mS cm −1 ). This high salinity is not surprising because the genus Echinogammarus is known to hold many salt tolerant species, such as Echinogammarus ischnus (Witt et al 1997;Santagata et al 2008;Ellis and MacIsaac 2009). The extra-continental non-native Amphipoda and Gastropoda are, however, much more salt tolerant than both their native and continental non-native counterparts.…”

“…Hence a considerable physiological variability could exist between populations of C. curvispinum from various localities. Its adaptation to freshwater may be due to the low salinity tolerance of the Baltic Sea population (Santagata et al 2008) and could also explain the low tolerance observed in the population of the Meurthe River. If this hypothesis is correct, the "lost" of its salinity tolerance strongly reduce the probability of its transfer via ballast waters.…”

Are salinity tolerances of non-native macroinvertebrates in France an indicator of potential for their translocation in a new area?

a b s t r a c tBecause of its geographic and economic position, the Western part of Europe and France is prone to biological invasions. Among the aquatic species non-native to France, a high proportion of these species are considered to be salt-tolerant. To verify this assumption, we compared the salinity tolerance of 18 native and non-native species in France in order to determine whether the introduced non-native species are more salt-tolerant than the native ones. Contrary to our expectations, our study shows that both native and non-native macroinvertebrate species from the same taxonomic group which had originated from within Eurasia had very similar salinity tolerance. Our results show that species originate from outside Eurasia (introduced by the ballast or drinking water on ships) were more salt tolerant than native from France and non-native species originated from Eurasia. Thus, derivation of the acute test of the salinity tolerance in native ranges may give good indications of their potential ability to survive during the translocation by shipping from the area of origin to another area. Our approach does provide empirical evidence for potential of non-native species to survive translocation in saline water using standard, quick and inexpensive protocols.

“…BWE and saltwater flushing reduce invasion risk by decreasing the number of individuals (propagule pressure) and number of species (colonization pressure) in ballast tanks by physical removal (i.e., purging). In addition, exposure to mid-ocean water may provide additional protection against fresh-and brackish-water taxa sensitive to osmotic stress (Santagata et al, 2008;Ellis and MacIsaac, 2009 , 2009). I propose here that sodium chloride (NaCl) brine -hereafter called only 'brine' -be used as an alternative treatment method for non-compliant tanks.…”
