Ecoclimatic Zones of the Earth

The effects of latitude, continental position, and elevation, together with other climatic factors, combine to form the world’s ecoclimatic zones, herein referred to as an ecosystem region, or ecoregion. Figure 5.17 shows the climatic zones where we might expect distinct ecosystem assemblages to occur. This map shows climatic units that are important to the climatologist and can be used to help determine ecosystem boundaries at the macroscale. Criteria for refining and delineating these zones, or ecoregions, at several levels of detail are presented below.
