What is Biogeography? Definition and Examples

📚 Quick Study Guide

• 🌍 Definition: Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.
• 🌱 Factors Influencing Distribution: These include geographic barriers (mountains, oceans), climate, resource availability, and evolutionary history.
• 🏞️ Types of Biogeography:
  • Historical Biogeography: Focuses on the evolutionary history of species.
  • Ecological Biogeography: Focuses on the current environmental factors.
• 🧭 Dispersal: The movement of organisms from one place to another.
• 🚧 Vicariance: The separation of a group of organisms by a geographic barrier.
• 🌡️ Climate's Role: Temperature and precipitation patterns significantly impact species distribution.
