  1. Each line corresponds to one jar
  2. Inventory number (NHMW), formaldehyde concentration in mg/l, and collecting date are given. (+) the given year is the time of determination (when the collection date is unknown)
  3. Two individuals per jar were analysed; the total number of jars per species is given in parentheses besides the species names followed by the percentage of overall PCR success (all marker sequences; 1968 PCRs in total)
