“…Although our findings show an apparent higher desiccation survival capacity of P. leniusculus face to the P. clarkii, the observed differences may simply reflect different conditions, namely the higher relative humidity (almost the double) during the P. leniusculus experiment. Under similar conditions, namely of temperature, other exotic freshwater crustaceans with a wide distribution across Europe, the Mediterranean river shrimp, Athyaephyra desmarestii (Banha and Anastácio, 2012) and the North American amphipod, Crangonyx pseudogracilis (Rachalewski, 2013) presented a survival capacity approximate 10 times lower than the presently studied species. These findings have several implications for the dispersal of these crayfish species both by active and passive means, including Human mediated transport.…”

Key-words: Pacifastacus leniusculus, Procambarus clarkii, desiccation survival, invasive species, dispersalThe signal crayfish, P. leniusculus and the red swamp crayfish, P. clarkii are two invasive crayfish species with widely world distribution, being both present at Iberian Peninsula. In this work we study the desiccation survival capacities of both species at 24 • C. Our results showed that both species are capable of surviving exposure to air for long periods of time, with an LT 90 of 17.6 and 21.5 h, respectively, for red swamp crayfish and signal crayfish. Our findings are in accordance with the great overland dispersal capacities attributed to these crayfish species. RÉSUMÉ Capacités de survie à la dessiccation des deux espèces d'écrevisses invasives Mots-clés :Pacifastacus leniusculus, Procambarus clarkii, survie à la dessiccation, espèces envahissantes, dispersion L'écrevisse signal, Pacifastacus leniusculus et l'écrevisse rouge des marais, Procambarus clarkii sont deux espèces d'écrevisses exotiques avec une distribution mondiale, toutes deux présentes dans la péninsule ibérique. Dans ce travail, nous étudions la capacité de survie à la dessiccation de P. clarkii à 24 • C et 30 % d'humidité relative et de P. leniusculus également à 24 • C, mais à une humidité relative de 50 %. Nos résultats ont montré que les deux espèces sont capables de survivre à l'exposition à l'air pendant de longues périodes de temps, avec une LT 90 de 17,6 et 21,5 h pour l'écrevisse rouge des marais et l'écrevisse signal, respectivement. Nos résultats sont en accord avec les grandes capacités de dispersion par voie terrestre attribuées à ces espèces d'écrevisse.Crayfish are one of the most commonly introduced freshwater organisms and are responsible for declines and extinctions of native species throughout the world (Guan and Wiles, 1997;Lodge et al., 1998Lodge et al., , 2000Nyström et al., 2001, Westman et al., 2002. The signal crayfish Pacifastacus leniusculus (Dana, 1852) and the red swamp crayfish, Procambarus clarkii (Girard, 1852) are two North America native crayfish species with worldwide distribution due to their economic importance, but also due to their high dispersal abilities, fast growing populations and wide niches (Hobbs et al., 1989). Severe negative impacts on invaded areas are attributed to these two crayfish species, such as competition with native species (Nyström, 1999), dissemination of the crayfish plague (Diéguez-Uribeondo et al., 1997), habitat and ecosystem changes (Geiger et al., 2005), negative effects on amphibian populations (Nyström, 1999; Cruz et al., 2008) and losses on economic activities such as rice production (Anastácio et al., 2005). In the Iberian Peninsula these two crayfish were first introduced into Spain nearly at the same time, P. clarkii in 1973 and P. leniusculus in 1974 respectively, for aquaculture purposes (Diéguez-Uribeondo et al., 1997;Alonso et al., 2000). In Portugal, the fist records of these species were in 1979 for P. clarkii in the Caia river (Ramos and Perei...

“…It is highly probable that the population in Portugal may be of European origin, as a further invasion step on the European continent. Bearing in mind the ability of C. pseudogracilis to cling to waterfowl (Rachalewski et al, 2013), the role of zoochory in the spread of this amphipod within Europe cannot be underestimated. However, it may not be excluded that it was introduced again from the same native area in the Louisiana, USA, that was the source for the previous introduction to Europe.…”

“…Indeed, the lack of amphipod competitors in this region and the wide range of potential dispersal vectors could promote a rapid expansion in the Iberian Peninsula, since natural vectors, e.g. waterfowl (Rachalewski et al, 2013) and those related with human activities, such as sport fishing, are very frequent in the area (Banha and Anastácio, 2015). Range expansion may also be enhanced due to the high suitability of environmental conditions found in most river networks, especially in the south of the Iberian Peninsula and in lowlands.…”

“…An often proposed natural mechanism for long-distance dispersal of aquatic invertebrates is hitch-hiking on the legs or plumage of, or via endozoochorous dispersal through, water birds (Charalambidou and Santamaría 2002;Green et al 2002;Frisch et al 2007;Rachalewski et al 2013). Experimental work by Rachalewski et al (2013) presented the possibility of Crangonyx amphipods hitchhiking on the legs or plumage of mallards; however, this was only for very restricted periods (less than 6 min) and a maximum flight distance of approximately 7 km.…”

For chiltoniid amphipods this mechanism is considered extremely unlikely as individuals would quickly die of desiccation once out of the water, especially considering that bridging distances in the Australian landscape are likely to be in the order of hundreds or thousands of kilometres.…”

Abstract. Recent molecular and morphological analyses have shown that chiltoniid amphipods, once thought to be a relictual group, are a diverse and speciose family of Australian freshwater amphipods. As part of a larger examination of the family, chiltoniids from Kangaroo Island in South Australia were collected and analysed using molecular (COI and 28S) and morphological methods in order to understand species distributional patterns and relationships. Kartachiltonia moodyi gen. nov., sp. nov., a spring-associated species endemic to the island, was discovered and populations of three additional mainland species (Austrochiltonia australis, A. dalhousiensis and A. subtenuis) were examined. The island populations of A. australis, A. dalhousiensis and A. subtenuis were found to form natural groups with differing haplotype coalescence times dating from the Early to Mid-Pleistocene. Numerous cycles of regional climate change throughout the Pleistocene are likely to have driven speciation in chiltoniid amphipods in southern Australia and the presence of multiple chiltoniid species at Kangaroo Island indicates that it exists at a likely convergence of species distribution patterns. Three possible hypotheses to explain the evolution and diversity of chiltoniids in southern Australia are discussed as are evidence for potential introduction and longdistance dispersal events.
