2). As a result, ecosystems of different climates differ significantly. Climate would appear to be, then, the initial criterion in defining ecosystem boundaries. Modifying landform should be next, with other criteria following. We discuss the validity of this premise in the following chapters. These climatic differences result from factors that control climatic regime, defined as the diurnal and seasonal fluxes of energy and moisture. We can illustrate different climatic regimes by studying climate diagrams, or climographs.

British Geog. 38; reprinted with permission of Blackwell Publishing. will screen out the effects of disturbance or plant succession, permitting identification regardless of what currently exists.

To show links between systems and to establish a hierarchy, they should be based on attributes common to all levels.

During the cold or dry season, most insects become dormant or die, leaving eggs or larvae behind to hatch in the following, more favorable season. Some higher mammals and birds hibernate; others migrate. Annual cycles are very apparent in the tropical grasslands and in midlatitudes. The rainforest and polar deserts are about the only regions that do not experience annual changes. Many plants and animals adjust to the changing length of day throughout the year. Reproduction, dormant periods, color changes, migration, and many other life patterns are adapted to moisture cycles (Hidore 1974; Fig.
