Biogeography is the study of the distribution of species and ecosystems across geographic space and through geologic time. It examines how factors such as climate, geography, and historical events influence the distribution and diversity of life on Earth.
The concepts of vicariance, dispersal, endemism, and migration help researchers understand the factors driving species distribution patterns, the formation of new species, the uniqueness of certain ecosystems, and the movement of organisms across landscapes over time.
