The biogeography of islands is a fascinating topic that extends to more than just island locations. Soon, the theory found other applications. Evolution & Biogeography!.

Over time, the Earth’s continents have separated, drifted apart, and collided, resulting in the creation of novel climates and habitats. It can be studied with a focus on ecological factors that shape the distribution of organisms, or with a focus on the historical factors that have shaped the current distributions.

Biogeography, as the study of place, not only links us back to the early plant and animal geographers of the past, but incorporates our observations of organisms and their distributions within space. First impressions are still important in the 21st century, but they look a little different. How to use biogeography in a sentence. Island biogeographic theory has been applied to many kinds of problems, including forecasting faunal changes caused by fragmenting previously continuous habitat. Biogeography is one of the oldest sub-fields of discipline, concerned with describing and explaining the spatial patterns of the distribution of living organisms: for example where the living organisms are, where they are not and why they are missing there.
