Appendix E. Figures showing the accumulation curves of trapped invertebrates for a number of dominant species, using the different trapping methods.


FIG. E1. Numbers of trapped invertebrates in pitfall traps placed in a Perspex enclosure (5-x50cm) increase asymptotically with time. A and D represent two common detritivore species, a gammarid amphipod (A) and a landsnail (D). B, C, E, and F represent three common predator invertebrates, a lycosid spider (B), Lady-bird beetle (C), ant (E), and bug (F).


FIG. E2. The rate of increase with which some abundant species were caught in the different stages of succession. (A) and (B) represent two common detritivore species which were caught with pitfall traps. (A) Amphipoda: Orchestia gammarellus (B) Gastropoda: Ovatella myosotis, a less mobile species. (C), (D), and (E) were caught with the pyramid traps. (C) Coleoptera: Coccinella undecimpuntata (D) Diptera: Fucellia maritima (E) Parasitica (all species). These species had an abundance of at least 5 individuals in 6 out of 7 stages (which is not the case for species in Fig. E1B, E1E, and E1F).
