Fig. 6. The estimated species richnesses of three carabid beetle groups in four hypothetical development scenarios: U, Undeveloped; D, Dispersed; SC, Semi-compact; C, Compact. (A) All beetles. (B) Forest beetles. (C) Open-habitat beetles. The species included in each group are given in Appendix 2. The lower edge of each box is the first quartile, the bold center line is the median, and the upper edge is the third quartile of the distribution. Whiskers extend to the minimum and maximum values. Species richness estimates for the Undeveloped and Dispersed scenarios had zero variance. This is because every beetle species collected in the four Forested survey sites (for the Undeveloped scenario) and the four Exurban survey sites (for the Dispersed scenario) was always estimated to be in at least one of the large number (91.83) of replicate site areas in these scenarios.
