Abstract

Freshwater crayfish, among the largest invertebrate members of biological communities in non-marine ecosystems throughout the world, have a functional role that is tightly linked to their trophic ecology both as consumers of a large variety of food sources and as prey for a number of vertebrate predators ranging from fish to mammals (Hogger 1988). Although the low diversity of crayfish species in Europe, as compared to that in North America, might suggest a low significance of this group to the functioning of the ecosystems, the recent introduction of several non-indigenous species has changed this view dramatically [ABSTRACT FROM AUTHOR]
