SPECIES OF BRANCHIOBDELLIDAE (ANNELIDA) ON FRESHWATER CRAYFISH IN SOUTH TYROL (NORTHERN ITALY)
Twenty-eight freshwater crayfish were collected from 8 streams and one small lake in the province of South Tyrol (North Italy) from autumn 1999 to spring 2001, in order to investigate the presence of branchiobdellidans.

Exponential increase of signal crayfish in running waters in Sweden – due to illegal introductions?
Sweden has only one indigenous species of crayfish, the noble crayfish (Astacus astacus, Fabricius). There has been a steady decline of noble crayfish populations in Sweden since 1907, mainly due to the crayfish plague.

Differential elemental accumulation of the signal crayfish (Pacifastacus leniusculus) along an invasion gradient [PDF]
The non-native signal crayfish (Pacifastacus leniusculus) can influence elemental cycling in aquatic ecosystems through bioaccumulation and transfer of chemical elements, with potential spatial variation along invasion gradients.

SHELTER COMPETITION BETWEEN TWO INVASIVE CRAYFISH SPECIES: A LABORATORY STUDY
Alien crayfishes represent a common threat to aquatic ecosystems. Their spread in Europe is leading to more frequent contacts between different invasive species populations. Shelter can be an important factor in the resulting interactions.
