In the year 2000, the benthic and hyporheic ostracod species were investigated in the groynes and the groyne fields of the river Elbe. In total only 12 species were found. The low number of species is owing to the few mesohabitats that occurred in the channel that was altered for navigation purposes, and that the river was severely polluted in the past, which led to an extinction of most species. Since about 1992 the Elbe is in a continuing phase of recolonization. Remarkably, the juveniles of the two species Pseudocandona albicans and Limnocythere inopinata occurred predominantly in the hyporheal within gravel of subaqueous dunes.
