Figure 1

Representation of the 13 simulated scenarios illustrating the composition of species with various DBI values across different community sizes (small, medium, large, and giant). Rows categorize species types based on DBI scores; ‘A’ (DBI = 8–9), ‘B’ (DBI = 4–5), ‘C’ (DBI = 2–3), or ‘D’ (DBI = 0–1), while columns delineate the specific scenarios devised for each community size. Light green species act as substitutes for ‘A’ and ‘B’ species when depleted, necessitating the selection of species with lower DBI values. This is particularly evident when constructing large and giant communities and the depletion of species with the corresponding DBI values occurs, prompting the inclusion of species from the nearest DBI categories. A bold line distinctly separates communities with a prevalence of high-scoring ‘A’ species, indicating scenarios where a shift to a high-scoring species scenario was made at the expense of the scenario that should have been in the given field according to the basic description of the figure.
