The invasive alien crayfish Pacifastacus leniusculus is considered harmful to freshwater pearl mussels Margaritifera laevis and M. togakushiensis. It also often colonises mussel habitats in Japan. In order to test the negative effects of alien crayfish on mussels, we evaluated the predation impact of signal crayfish on freshwater pearl mussels in vitro. We tested the relationship between the survival/injury rates of mussels and crayfish predation with respect to different sizes of mussels (four… Expand

A tale of shells and claws: The signal crayfish as a threat to the pearl mussel Margaritifera margaritifera in Europe.
TLDR
It is clearly demonstrated that the signal crayfish predates pearl mussels in natural conditions and detected a significant density dependent effect (i.e., sites with more craysfish presented higher number of pearl mussel shells with marks of predation). Expand
Invasive crayfishes as a threat to freshwater bivalves: Interspecific differences and conservation implications.
TLDR
The results support the idea that P. clarkii and P. leniusculus can affect native freshwater bivalves, but clear interspecific differences were detected. Expand
Predation of freshwater bivalves by invasive crayfishes
TLDR
The results of this study support the idea that P. clarkii and P. leniusculus can affect native bivalve populations by reducing the number of effectives by increasing mortality and by reducing their fitness, which may have indirect impacts on freshwater ecosystems. Expand
Comparison of trophic function between the globally invasive crayfishes Pacifastacus leniusculus and Procambarus clarkii
TLDR
Trophic differences between the globally cosmopolitan crayfishes P. leniusculus and P. clarkii are pointed to, particularly when accounting for the ways that ecosystem context can affect food web structure of communities and the trophic resources available to these consumers. Expand
Evaluation of cage traps to control the invasive signal crayfish (Pacifastacus leniusculus) in Lake Harutori
TLDR
It is concluded that the conger cage is the most efficient trap to capture crayfish in Lake Harutori. Expand
A review of the use of physical barriers to stop the spread of non-indigenous crayfish species
TLDR
This review reflects current knowledge on how to stop migration when NICS are established and provides useful information for the construction of barriers. Expand
Major shortfalls impairing knowledge and conservation of freshwater molluscs
Molluscs are among the most diverse and widespread animal groups in freshwater habitats. Unfortunately, like most freshwater taxa, they are decreasing dramatically and are now among the mostExpand
Getting What Is Served? Feeding Ecology Influencing Parasite-Host Interactions in Invasive Round Goby Neogobius melanostomus
TLDR
Examination of predator-prey interactions and parasitization patterns of the highly invasive round goby in the rivers Rhine and Main in Germany revealed a broad prey spectrum and parasite intensities differed between rivers, suggesting that final hosts (large predatory fishes) may influence host-parasite dynamics of N. melanostomus in its introduced range. Expand
Claw size predicts dominance within and between invasive species of crayfish
TLDR
In crayfish and other species that have invasive potential, future investigations into intraspecific versus interspecific communication dynamics are warranted as they may shed light on the successes and failures of past and present species introductions. Expand

Predation by the invasive American signal crayfish, Pacifastacus leniusculus Dana, on the invasive zebra mussel, Dreissena polymorpha Pallas: the potential for control and facilitation
TLDR
Signal crayfish are, therefore, unlikely to be able to significantly impact established populations of zebra mussels in the wild, although zebraMussels have the potential to provide cray fish with a substantial food source. Expand
Size-dependent impacts of invasive alien crayfish on a littoral marsh community
TLDR
Overall, functional roles of signal crayfish as omnivores and ecosystem engineers remained similar during the ontogenetic stage but the magnitude and rate ofcrayfish impacts intensified with increasing cray fish size, suggesting removal of large invasive cray Fish alone may reduce detrimental impacts on aquatic biodiversity. Expand
Crayfish predation on the common pond snail (Lymnaea stagnalis): the effect of habitat complexity and snail size on foraging efficiency
TLDR
The results suggest that crayfish can structure the abundance and size distribution of thin-shelled snails, through size-selective predation and reduction of macrophytes. Expand
Sex- and size-specific migration patterns and habitat preferences of invasive signal crayfish (Pacifastacus leniusculus Dana)
TLDR
It is suggested that local population characteristics, particularly the density, size-distribution and sex ratios, can strongly influence the dispersal ability of invasive crayfish. Expand
Strategies for the conservation of endangered freshwater pearl mussels (Margaritifera margaritifera L.): a synthesis of Conservation Genetics and Ecology
TLDR
This article summarises the current information about the species’ systematics and phylogeny, its distribution and status as well as about its life history strategy and genetic population structure and based on this information, integrative conservation strategies for freshwater mollusc species which combine genetic and ecological information are discussed.

COMPETITION FOR SHELTER OF PREFERRED SIZES BETWEEN THE NATIVE CRAYFISH SPECIES CAMBAROIDES JAPONICUS AND THE ALIEN CRAYFISH SPECIES PACIFASTACUS LENIUSCULUS IN JAPAN IN RELATION TO PRIOR RESIDENCE, SEX DIFFERENCE, AND BODY SIZE
TLDR
The body-size advantage strongly influenced the outcome of the both intra- and inter-specific contests regardless of residents or intruders and overcame the prior residence effect in both species. Expand
Effect of Muskrat Predation on Naiads
TLDR
While both freshwater mussel faunas are especially threatened by human activities, they face differing threats from introduced species due to marked differences in their evolutionary history. Expand
Species Displacement Between an Introduced and A ‘vulnerable’ Crayfish: The Role of Aggressive Interactions and Shelter Competition
TLDR
Paired comparison of agonistic behaviours in mixed species groups revealed that Pacifastacus exhibiting frequently more aggressive attacks while Camaboides showing more defensive behaviours to their respective counterparts, which can be a critical disadvantage for Cambaroides if shelters are limited in natural situations. Expand
The influence of multiple introduced predators on a littoral pond community
TLDR
It is demonstrated that noninteracting, introduced multiple predators can have strong direct and indirect effects on multiple trophic levels in pond communities, andTrophic cascades may develop in aquatic food webs even with omnivores such as crayfish, and in complex habitats with trout. Expand
Freshwater pearl mussels show plasticity of responses to different predation risks but also show consistent individual differences in responsiveness
TLDR
It is found that mussels within a group showed shorter closure times than solitary mussels, consistent with decreased vulnerability to predation in group-living individuals, and individuals showed significant consistency in their closure responses across the trial series, in line with behavioural syndrome theory.
