“…Macrophytes are particularly important to aquatic environments because they function as service providers and ecosystem engineers (Jones et al, 1994;1997;Duarte, 2000) avoiding erosion, facilitating nutrient cycling and providing habitat to associated faunal communities (Duarte, 2000;de Groot et al, 2002;Gurnell et al, 2006), and serious changes may occur in aquatic environments if submersed plant species are overgrazed. Additionally, the burrowing behaviour might also cause river or channel bank erosion and increase water turbidity (Anastácio and Marques, 1997;Rodríguez et al, 2003). These changes in water characteristics alter aquatic ecosystems and are believed to induce cyanobacterial blooms (Yamamoto, 2010).…”

Red swamp crayfish: biology, ecology and invasion - an overview

-Alien species have been transported and traded by humans for many centuries. However, with the era of globalization, biological invasions have reached notable magnitudes. Currently, introduction of alien species is one of the major threats to biodiversity and ecosystem functioning. The North American crayfish Procambarus clarkii is one of the most widely introduced freshwater species in the world, especially due to its high economic importance. It is responsible for great modifications in invaded environments causing irreparable ecological and economic damages. Its impressive ability to successfully colonize a wide range of environments is a consequence of its behavioural and biological characteristics that can adapt to features of the invaded location, conferring to this species a notable ecological plasticity. This review summarizes the available information regarding P. clarkii's biology and invasive dynamics around the world in order to contribute to the understanding of the threats posed by its establishment, as well as to support management and impact mitigation efforts.

“…microcystin) in its organs and tissues (E. Tricarico et al, unpublished data). Its habit of burrowing (Barbaresi et al, 2004) aids the crayfish to withstand environmental extremes like dehydration, but it may also cause bank collapse and increased water turbidity with the consequent inhibition of primary production (Rodríguez et al, 2003) and structural damages to cultivated fields (Correia & Ferreira, 1995;Huner, 2002). The negative impact of this species on both macrophytes and macroinvertebrates has been experimentally proved (Acquistapace et al, 2006;F.…”

This study analyzes the population structure and dynamics of an invasive population of Procambarus clarkii (Girard, 1852) in a Mediterranean wetland using the Bhattacharya's and Von Bertallanfy's analytical methods. The main purpose was to collect biological data necessary for the management of this nuisance species. A maximum of five age classes were identified for both sexes, three of which being composed of a few or zero individuals. Age classes were classified into two subgroups--spring (SpL) and summer (SuL) lines--on the basis of the different hatching periods. Individuals of SpL showed a faster growth rate and reached a larger body size than those belonging to SuL, probably because they were able to grow for a longer time. No between-sex differences were found in growth patterns except for the asymptotic length (L ¥ ), which was reached faster by the females. Other population properties were analyzed, such as a high mortality rate, a maximum longevity of 4 years, and a low mean life-time (<12 months). Finally, a relatively small fraction of individuals seemed to survive after the first reproductive peak in spring. Consequently, the structure and dynamics of the study population seem to reveal its stability and spreading potential, as a confirmation of the invasiveness of P. clarkii in Mediterranean wetlands.

“…Although there are limited aquatic links to these water bodies, P. clarkii can easily move across land (Chucholl, 2011a) or the species could spread by piscivorous birds and through deliberate and accidental introductions by humans. These sites are nationally important for breeding and wintering birds, and in warmer climates it has been observed that the introduction of P. clarkii can cause loss of macrophytes and ultimately loss of avian diversity and abundance (Rodriguez et al, 2003). Amphibian species richness can also be reduced in the presence of P. clarkii (Cruz et al, 2006) through direct predation on eggs and larvae as well as habitat modification.…”

Key-words:freshwater crayfish, Procambarus clarkii, conservation, British isles, invasive speciesThe Louisiana red swamp crayfish Procambarus clarkii is highly invasive. It is now common in Europe where it is causing problems to native wildlife and structural damage to habitats. Procambarus clarkii was first recorded in Britain in 1991 and is currently found in the Hampstead Heath ponds and Regents Canal in London, as well as a small lake 15 km outside of Greater London. This paper considers how conditions in Britain affect the life cycle, breeding habits and potential range expansion of P. clarkii. Results of trapping surveys are presented in an effort to map the current distribution of P. clarkii and predict which areas it could colonise in the future. The ecological impact of potential colonisation is discussed by considering the impact P. clarkii has in mainland Europe. It is concluded that P. clarkii is likely to spread from Regents Canal into the nearby Brent, Crane, Colne, Lee and Thames catchments within 50 years. This time would be reduced significantly if further deliberate or accidental introductions by humans occur since this is deemed a far greater risk than natural expansion. P. clarkii is expected to have a negative impact on aquatic ecosystems in Britain and therefore tighter enforcement is needed to slow the spread of this species. RÉSUMÉRépartition actuelle et future propagation de l'écrevisse rouge de Louisiane Procambarus clarkii (Crustacea, Decapoda, Astacida, Cambaridae) en Grande-Bretagne : implications pour la conservation des espèces indigènes et des habitats Mots-clés :L'écrevisse rouge de Louisiane Procambarus clarkii est très envahissante. Elle est maintenant fréquente en Europe où elle est à l'origine de problèmes à la faune indigène et de dommages structurels sur les habitats. Procambarus clarkii a été signalée la première fois en Grande-Bretagne en 1991 et se trouve actuellement dans les étangs Hampstead Heath et le Regents Canal à Londres, ainsi que dans un petit lac à 15 km du Grand Londres. Le présent document examine conservation, îles Britanniques, espèces envahissantes comment les conditions en Grande-Bretagne affectent le cycle de vie, les traits de la reproduction et l'étendue potentielle d'expansion de P. clarkii. Les résultats de recherches par piégeage sont présentés en vue de cartographier la distribution actuelle de P. clarkii et de prédire quels domaines elle pourrait coloniser à l'avenir. L'impact écologique de la colonisation potentielle est discuté en tenant compte de l'impact P. clarkii en Europe continentale. Il est conclu que P. clarkii est susceptible de se propager à partir de Regents Canal dans les milieux proches de Brent, Crane, Colne, Lee et le bassin de la Tamise dans les 50 ans. Cette vitesse d'expansion devrait être sensiblement accélérée si les introductions délibérées ou accidentelles par l'homme se produisent car cela est considéré comme un risque beaucoup plus grand que l'expansion naturelle. P. clarkii est considérée comme ayant un impact ...
