dc.description.abstract | The introduced North American signal crayfish Pacifastacus leniusculus (Dana) has replaced the native
noble crayfish (Astacus astacus) in many European freshwaters and can be considered a new component of these
ecosystems. The 2 species are apparently similar in many respects, but their ecological equivalence is uncertain and
has been little investigated, especially at the whole-lake scale. We compared the effects of the 2 species on the
abundance, species richness, and composition of littoral macroinvertebrate assemblages in a set of small- and mediumsized
boreal lakes, which included 8 lakes with noble crayfish, 8 lakes with signal crayfish, and 8 lakes without
crayfish. We collected semiquantitative littoral macroinvertebrate samples with a kick net from 3 replicate sites
in each lake. The abundance of invertebrates did not differ significantly among the 3 lake categories, but lakes with
crayfish had lower species richness than lakes without crayfish. Mollusk taxa, in particular, were fewer in lakes with
crayfish. Assemblage composition also differed between lakes with and without crayfish. However, macroinvertebrate
species richness and composition did not differ between lakes with signal or noble crayfish, indicating that
the 2 crayfish species are ecologically equivalent with respect to their effects on shallow, littoral invertebrate assemblages
of boreal lakes. | |
