Subterranean Pitfall Traps: Is It Worth Including Them in Your Ant Sampling Protocol?

Table 2

List of all ant species collected with subterranean pitfall traps and list of all cryptobiotic species (marked with an asterisk) found during the study. Shown is the number of records (i.e., number of traps in which the species was present) of each species in different habitats, soil depths, and in total. The total number of records for each species in the conventional traps is also provided.
