Definition: Biogeographical refers to the study of the distribution, diversity, and evolutionary history of living organisms across different geographical regions. It is a field that focuses on understanding how species move from one place to another, how they interact with their environment, and how they adapt to changing conditions in order to survive and thrive. Biogeography is an interdisciplinary discipline that involves studying the relationships between ecosystems, populations, and species, as well as the processes that shape these relationships over time.
