10.6.4. Zonation

Within any community at any given time, species are distributed according to their specific abiotic requirements. In other words, species distribution exhibits zonation or belt formation. A classic example is the distribution of Algae and animals on a rocky seashores, extending from the splash zone (supralittoral) through the intertidal zone (littoral) down to the permanently submerged seabed (sublittoral). Physical parameters—most notably the duration of exposure to air during low tide—change gradually from land to sea, which directly affects the species composition of these communities. This type of zonation is discussed in detail in Section 11.4. Another clear example is the altitudinal zonation observed when climbing a mountain (Fig. 10.14). Visually, zonation may resemble successive stages of succession and, in some cases—such as the ecotone between a forest and an abandoned field—it actually corresponds to it. However, one must recognize the fundamental difference between zonation and succession: zonation represents a spatial turnover of species, whereas succession represents a temporal one.
