The Secretariat of the International Commission for the Protection of the Danube River (ICPDR) coordinated the implementation of JDS2.
Similar to the first survey, JDS 2 had several specific objectives:

The purpose of this collaboration was the resettlement of the Palingenia longicauda mayfly in some running waters of Germany.
The role of the Palingenia mayfly in running waters is very important. The larvae use the materials of the bottom by bioturbation. They are also important members of food-web in running waters.
Earlier Palingenia longicauda was a characteristic benthic species of middle and lower ... [more...]
