“…It was at first observed occasionally in the Baltic Sea (Ojaveer et al, 2007) and its breeding ecology suggested that no self-sustaining populations could be formed in low salinity waters (Anger, 1991). Today, however, the number of observations reported in Baltic waters has increased and an established population has been described (Drotz et al, 2010;Otto and Brandis, 2011).…”

Marine biological invasions have increased with the development of global trading, causing the homogenization of communities and the decline of biodiversity. A main vector is ballast water exchange from shipping. This study evaluates the use of ecological niche modelling (ENM) to predict the spread of 18 non-indigenous species (NIS) along shipping routes and their potential habitat suitability (hot/cold spots) in the Baltic Sea and Northeast Atlantic. Results show that, contrary to current risk assessment methods, temperature and sea ice concentration determine habitat suitability for 61% of species, rather than salinity (11%). We show high habitat suitability for NIS in the Skagerrak and Kattegat, a transitional area for NIS entering or leaving the Baltic Sea. As many cases of NIS introduction in the marine environment are associated with shipping pathways, we explore how ENM can be used to provide valuable information on the potential spread of NIS for ballast water risk assessment.

“…Further, the extent of overlap is likely to be far greater than recorded due to underreporting of E. sinensis occurrence (Mitten Crab Recording Project, 2013). Despite their expanding populations and increasing sympatry, no study has compared the feeding ecology of the two species, and for E. sinensis, we currently lack any quantitative data on feeding rates, both of which hinder reliable impact assessment (Ojaveer et al, 2007). Interspecies comparison is a valuable tool for forecasting potential impacts of established invaders for which very little ecological information is available (e.g.…”

Feeding behaviour, predatory functional responses and trophic interactions of the invasive Chinese mitten crab (Eriocheir sinensis) and signal crayfish (Pacifastacus leniusculus)

SUMMARY1. Freshwaters are subject to particularly high rates of species introductions; hence, invaders increasingly co-occur and may interact to enhance impacts on ecosystem structure and function. As trophic interactions are a key mechanism by which invaders influence communities, we used a combination of approaches to investigate the feeding preferences and community impacts of two globally invasive large benthic decapods that co-occur in freshwaters: the signal crayfish (Pacifastacus leniusculus) and Chinese mitten crab (Eriocheir sinensis). 2. In laboratory preference tests, both consumed similar food items, including chironomids, isopods and the eggs of two coarse fish species. In a comparison of predatory functional responses with a native crayfish (Austropotamobius pallipes), juvenile E. sinensis had a greater predatory intensity than the native A. pallipes on the keystone shredder Gammarus pulex, and also displayed a greater preference than P. leniusculus for this prey item. 3. In outdoor mesocosms (n = 16) used to investigate community impacts, the abundance of amphipods, isopods, chironomids and gastropods declined in the presence of decapods, and a decapod >gastropod >periphyton trophic cascade was detected when both species were present. Eriocheir sinensis affected a wider range of animal taxa than P. leniusculus. 4. Stable-isotope and gut-content analysis of wild-caught adult specimens of both invaders revealed a wide and overlapping range of diet items including macrophytes, algae, terrestrial detritus, macroinvertebrates and fish. Both decapods were similarly enriched in 15 N and occupied the same trophic level as Ephemeroptera, Odonata and Notonecta. Eriocheir sinensis d 13 C values were closely aligned with macrophytes indicating a reliance on energy from this basal resource, supported by evidence of direct consumption from gut contents. Pacifastacus leniusculus d 13C values were intermediate between those of terrestrial leaf litter and macrophytes, suggesting reliance on both allochthonous and autochthonous energy pathways. 5. Our results suggest that E. sinensis is likely to exert a greater per capita impact on the macroinvertebrate communities in invaded systems than P. leniusculus, with potential indirect effects on productivity and energy flow through the community.

“…The geographical origin of the CMC in the Oder River in Poland, which is not self‐sustainable, is suggested by several researchers (Ojaveer et al 2007; Czerniejewski et al 2007) to be from the Elbe River population. Here our ITS 1 and ITS 2 sequence results support this theory (Fig.…”

“…1, 2) independent of how gaps were treated. Distribution possibilities of CMC from the Elbe River waterways into the Baltic Sea are numerous (Gruszka 1999; Herborg et al 2003, 2007c; Ojaveer et al 2007): the waterways of Elbe are linked by canals like the Havel‐Elbe canal and in the area of Berlin connections goes via the Spree‐Oder canal and both canals connects Elbe to the Oder River system. In the northern part of Elbe is the Elbe‐Lübeck Canal which is a link to the Baltic Sea (Lübeck Bight/Bay of Mecklenburg).…”

“…Since its introduction into Europe (river Alder 1912) has the range of its occurrence extended considerably, especially during the last 15 years, most probably because of intense marine traffic (Herborg et al 2007a; Drotz et al 2010a). In Europe it is now found from in both the Bothnian Sea as the Baltic Sea, along the Atlantic coast (both mainland as the British Isles) into the Mediterranean Sea, Black Sea, Caspian Sea and also the Sea of Azov (Panning 1939; Petit and Mizoule 1974; Clark et al 2006; Robbins et al 2006; Ojaveer et al 2007; Lundin et al 2007; Drotz et al 2010a). In North America, these crabs have been observed on both along the Atlantic as the Pacific coasts (Rudnick et al 2000, 2005; Ruiz et al 2006).…”

The highly invasive Chinese mitten crabs (Eriocheir sinensis) was studied to reveal the genetic relationship between three none self‐sustainable population within the Polish Oder and Vistula River and Lake Vänern in Sweden. Crabs from self‐sustainable populations were collected from the Elbe River (Germany), San Francisco Bay (USA) and five Asian river estuaries. Both parsimony and maximum likelihood analysis of the nuclear ITS 1 and ITS 2 regions reveal a similar topological pattern. The mitochondrial cytochrome c oxidase subunit I (COI) sequence had too low resolution to be informative. The Oder River haplotypes showed high sequence similarities to both the Elbe population and/or the native spawning areas in China. The Vistula River showed haplotypic similarity to specimens from the Oder River in Poland or the Elbe River. Also high sequence similarities were observed to the specimens from the Swedish Lake Vänern indicating to an origin from the River Elbe. Minor changes in evolutionary interpretation exist depending on how gaps are treated and the analytic method. There is a complex movement involving back and forth transoceanic colonization of the Chinese mitten crab haplotypes. Invasion routes are discussed in relation to ship transfer routes and canal waterways.
