Analysis of a global elevation database to measure changes in
shallow-marine habitat area as a function of sea-level reveals an
unexpectedly complicated relationship. In contrast to prevailing views,
sea-level rise does not consistently generate an increase in shelf area,
nor does sea-level fall consistently reduce shelf area. Different
depth-defined habitats on the same margin will experience different
changes in area for the same sea-level change, and different margins will
likewise experience different changes in area for the same sea-level
change. Simple forward models incorporating a species-area relationship
suggest that the diversity response to sea-level change will be largely
idiosyncratic. The change in habitat area is highly dependent on the
starting position of sea level, the amount and direction of sea-level
change, and the habitat and region in question. Such an idiosyncratic
relationship between diversity and sea-level reconciles the widespread
evidence from the fossil record for a link between diversity and sea-level
change with the lack of quantitative support for such a relationship
throughout the Phanerozoic.
