“…Our results also suggest that in the study area none of the species had a substrate preference. In fact other authors (Gil-Sánchez and Alba-Tercedor, 2002;Cruz and Rebelo, 2007) also indicated an absence of association between crayfish distribution and substrate composition. The fact that crayfish predate river shrimp and that these two species share the same microhabitats indicates a probable impact of crayfish on river shrimp populations.…”

Key-words:interaction, Athyaephyra desmarestii, Procambarus clarkii, predation, habitat use In the south of Portugal there are only two species of strictly freshwater decapods: the native freshwater shrimp Atyaephyra desmarestii and the exotic crayfish Procambarus clarkii. The aim of this study is to understand if the exotic crayfish acts as river shrimp predator and if both species share the same type of microhabitat. We performed laboratory experiments to study predation and conducted field work in the river Sorraia to verify the microhabitat distribution of both species. Laboratory experiments demonstrated significant predation on river shrimp for crayfish with a cephalothorax length (CT) over 24 mm. The average daily consumption increases with crayfish CT to a maximum of 0.8 shrimps at 44 mm. Field work confirmed that both species share the same microhabitats although with small differences e.g. on the water quality variables such as conductivity and the percentage of oxygen saturation. These microhabitats are shallow pools with abundant aquatic vegetation with no preference for the type of substrate. In the field, both crayfish density and its cephalothorax length are negatively correlated with shrimp densities. In conclusion, P. clarkii can predate A. desmarestii and the major impacts are expected at high densities of large sized crayfish. RÉSUMÉ Interactions entre écrevisse invasive et crevette native en rivière Mots-clés :interaction, Athyaephyra desmarestii, Procambarus clarkii, prédation, habitatDans le sud du Portugal, il n'y a que deux espèces de décapodes strictement d'eau douce : la crevette indigène d'eau douce Atyaephyra desmarestii et l'écrevisse exogène Procambarus clarkii. Le but de cette étude est de comprendre si l'écrevisse exogène agit comme prédateur de la crevette et si les deux espèces partagent le même type de microhabitat. Des expériences de laboratoire ont été réalisées pour étudier la prédation et des travaux sur le terrain dans la rivière Sorraia pour vérifier la distribution des microhabitats des deux espèces. Les expé-riences de laboratoire montrent une prédation significative sur la crevette palomète par l'écrevisse dont la longueur du céphalothorax (CT) est supérieure à 24 mm. La consommation moyenne journalière augmente avec la taille CT de l'écrevisse jusqu'à un maximum de 0,8 crevette à 44 mm. Le travail de terrain confirme que les deux espèces partagent les mêmes microhabitats bien qu'avec de petites différences concernant des variables de qualité des eaux comme la conductivité et le pourcentage de saturation en oxygène. Ces microhabitats sont des calmes peu profonds avec une abondante végétation aquatique sans préférence pour le type

“…The present distribution of these species reflects their high dispersal capabilities, high population growth rates and wide niches, which makes them very successful invaders (Hobbs et al, 1989) but also years of successive illegal translocations (Alonso et al, 2000;Diéguez-Uribeondo, 2006).

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...

“…rocks, submerged logs) used by crayfish as refuge, which can either increase the likelihood for predation due to increased exposure or cause crayfish to be physically washed downstream and thus, reduce population abundance in newly colonized habitats. Although both species have been shown to be good dispersers that can quickly re-colonize streams following disturbance (in contrast to native crayfish), high stream flow often hinders the upstream dispersal abilities of crayfish and thus, likely limits invader abundance (Bubb et al 2006;Cruz and Rebelo 2007).…”

Scale dependent effects of native prey diversity, prey biomass and natural disturbance on the invasion success of an exotic predator

There is growing support for the general notion that the drivers of invasion success often shift from biotic to abiotic factors with increasing spatial scale. Most of this research, however, has been conducted on a single trophic level; i.e. it has primarily looked at how the diversity of native competitors may influence invasion success. Less attention has been paid to understanding how native prey diversity may influence the invasion success of exotic predators and whether such biotic factors are scale-dependent. We used a hierarchical spatial survey of 17 stream communities to test whether native prey diversity, along with native prey biomass, algal resource abundance and annual stream discharge, influenced the abundance of an exotic crayfish predator, and whether the importance of these factors were scale-dependent. We used a hierarchical generalized linear model to evaluate the influence of these community and stream characteristics on exotic crayfish abundance at both the transect scale (1 m 2 ) and the stream scale (400 m 2 ). Our results indicated that at the stream scale, high stream discharge significantly limited invader abundance. However, at the smaller transect scale, native prey biomass was a significant driver of invasion success and positively correlated with invader abundance. We suggest that our results add to the emerging pattern that abiotic processes are stronger determinants of invasion success at large spatial scales, whereas biotic processes become more important with decreasing spatial scale. However, for predator invasions, prey biomass, not prey diversity may be a more important for driver of invasion success at small spatial scales.
