3rd German Intercalibration Exercise

by Jonas Zimmermann |

Each participant receives two prepared permanent slides. The samples are taken from a lowland lake in northern Germany and from a stream in the Central German Highlands. The results will be submitted in a predefined excel table. The template will include a list of taxa together with their associated most recent German data processing number (dv-numbers). Each participant will receive detailed instructions together with the permanent slides. Participation in the intercalibration exercise will cost 250 € (net) + 47.20 € (19% VAT), i.e. 297.50 € gross. There will be no workshop. Dr. Krisztina Buczko (Hungarian Natural History Museum, Budapest), Prof. Dr. Bart Van De Vijver (Botanic Garden Meise, Belgium) and Dr. Carlos E. Wetzel (Luxembourg Institute of Science and Technology, LIST, kindly taken over from Dr. Luc Ector *1962-2022) agreed to function as auditors.
