Benthic diversity (Shannon Index) on the Antarctic shelf predicted for a broad range of disturbance rates, using an analytical model based on different stages of recolonization (black line). Three values from empiric studies in the eastern Weddell Sea (small black quadrats +/-SD) and two scenarios from a similar spatially explicit model (large coloured quadrats) are superimposed; former ice scours (coloured lines) range from early (red/yellow) to intermediate (green) and climax stages (blue). The scenario in the upper left corner has a higher stage-diversity (more colours) than the lower, which represents a completely disturbed community with only early and intermediate stages of recolonization, but no climax.
