biogeographic region  biogeographic region, area of animal and
plant distribution having similar or shared characteristics
throughout.   Geographic regions around the world that have
similar environmental conditions are capable of harbouring the
same type of biota. This situation effectively separates the
biosphere into biomes—ecological communities that have the same
climatic conditions and geologic features and that support
species with similar life strategies and adaptations. The biome
is the fundamental unit of which larger biogeographic regions
(floral kingdoms and faunal realms) consist. The tropical forest
is one type of terrestrial biome; it is located at various
points around the planet where climatic and geologic conditions
produce similar environments. The tropical forest biome contains
the same general kinds of biological communities wherever it
occurs; however, the individual species will not be the same
from one tropical forest to another. Instead, each forest will
support organisms that are eco
