Abstract
We sampled chydorids (Branchiopoda, Anomopoda) from 29 Irish lakes between June 1996 and July 1997 in order to assess the usefulness of this group as an indicator of lake ecological quality, as required by the recently published EU Water Framework Directive. The lakes represented a wide range of the physicochemical conditions found in Irish lakes We identified 31 species of Chydoridae from the lakes and used multivariate analysis to elucidate the relationship between the chydorids and their environment Groups of lakes were found to have distinct chydorid communities, the structure and composition of which depended on environmental variables such as total phosphorus, total nitrogen, alkalinity, conductivity and lake size. The study highlights the potential value of this group as a biotic indicator of ecological change in Irish lakes.
