Relationship between productivity (%) and alternative biodiversity indices using rank-species. For each, on left fitted mean relationship and on right inserted scattergram for a randomly reduced sample (to 5%) of the same data field. (a). Gradient ( ) of log abundance/rank graph geometric series fitted to first five species. (b). Shannon H index for available species.
