Biogeography

Definition

Biogeography is the study of the geographic distribution of species and ecosystems in relation to historical, climatic, and ecological factors. It aims to understand patterns of biodiversity and the processes that result in these patterns.

5 Must Know Facts For Your Next Test

1. Biogeography helps explain why similar species are found on different continents due to continental drift.
2. Island biogeography is a key concept explaining the diversity and extinction rates on islands.
3. Biogeographic regions are areas with distinct assemblages of species influenced by geographical barriers.
4. The theory of plate tectonics plays a crucial role in shaping current biogeographic patterns.
5. Human activities significantly impact biogeographic distributions through habitat destruction and climate change.
