Definition: Biogeography, in biology and geography, refers to the study of how different species live and move across geographic boundaries. It encompasses a wide range of topics including migration patterns, ecological interactions, habitat use, population dynamics, and environmental influences on species distribution. Biogeographers analyze these relationships using various methods such as satellite imagery, remote sensing data, and GIS technology. They also investigate the impact of human activities such as agriculture, urbanization, and pollution on biodiversity.
