zonation

the division of a BIOME into zones that experience particular physical conditions. This is particularly clear in the distribution of animals and plants on the rocky seashore, where, for example, the sublittoral zone (below low water mark) is followed by the lower shore, middle shore, upper shore and splash zone, each with their characteristic flora and fauna. See SEA ZONATION and Fig. 276 .
