How does vertical zonation affect where people live?

Consequently, vertical littoral zonation is a consistent pattern at a regional scale within the same biogeographical zone. While their distribution varies at the same shore height, marine species and assemblages from rocky shores show a specific vertical sequence known as zonation. Vertical zonation is the idea that different types of plants grow at different elevations because the temperature becomes colder as you gain elevation.
