Appendix C. Full arthropod data tables, basic statistics, and comparisons of encountered species numbers with total Dutch species lists. From this appendix, the extent and nature of the data and possible differences between groups may be judged.
Links to the full data table for each of the studied arthropod groups can be found below.

Full arthropod data tables for each of the studied arthropod groups, including basic statistics.
These data sheets (see links below) contain the data for each of the arthropod groups studied. Abundances (no. individuals) are recorded into classes in these sheets, usually ranging from 1–9 (for grasshoppers the raw data already were classes). A legend is provided with each table. During the analyses, actual abundances were used (often log-transformed; see Table 1 in article text), not the classes shown in this appendix. |
In the tables, sites and species have been orderd to visualize internal data structure. The presented order has no special status or relationship to the study, not should it be considered in any way optimal. The only incentive for ordering the tables was to accentuate data structure. |
