The VII International Symposium on Tardigrada

The congress was attended by 35 researchers from 8 countries from three continents (Asia, Europe and North America). During the three days of the meeting 21 talks and 11 posters were presented.

This was the first time a tardigrade conference was held in Germany.

Proceedings

The Symposium talks have been published in a special volume of 'Zoologischer Anzeiger'. The volume contains 22 scientific papers on tardigrade morphology, taxonomy, phylogeny, evolution, biogeography, faunistics, ecology, physiology and reproduction. The symposium proceedings are dedicated to the memory of Dr. Vladimir I. Biserov.
