The SMNG collection of free-living soil nematodes and tardigrades was started in 1998. All specimens derive from soil ecological project studies. The main part of the nematode specimens is stored species and project specifically in small vessels at 4°C in the refrigerator (water, <1%TAF) and only a small part was yet transferred to permanent slides, embedded in glycerol. Tardigrade specimens were all transferred to permanent slides, embedded in Faure’ medium or Hoyer’ medium.
