Biogeography: Meaning & Definition
Biogeography is the scientific study of the distribution of species, organisms, and ecosystems across geographical space and through geological time. It examines how biological communities vary across different regions and how factors like climate, geography, and evolution influence these patterns.
Definition of Biogeography:
“Biogeography is the branch of science that explores the spatial distribution of living organisms and how ecological and historical factors shape this distribution.”
Key Aspects of Biogeography:
- Ecological Biogeography: Focuses on how current environmental factors (climate, habitat, competition) influence species distribution.
- Historical Biogeography: Studies past events like continental drift and glaciations that shaped species dispersal.
- Evolutionary Biogeography: Examines how species evolve in response to geographical barriers and environmental changes.
- Conservation Biogeography: Helps in biodiversity conservation by analyzing species extinction risks and habitat loss.
Why is Biogeography Important?
- Helps understand biodiversity patterns.
- Explains species migration & extinction.
- Assists in wildlife conservation & ecosystem management.

What is Biogeography?
Definition:
Biogeography is the scientific study of the distribution of living organisms—plants, animals, and microbes—across geographic spaces and through geological time.
Meaning (in simple terms):
Biogeography explains where species live, why they live there, and how they got there. It helps scientists understand patterns of biodiversity based on climate, geography, evolution, and ecological interactions.
Key Focus Areas in Biogeography:
Type of Biogeography | Focus |
---|---|
Historical | How species’ past movements (e.g., continental drift) affect current distribution |
Ecological | How current environmental factors (e.g., temperature, rainfall) affect species’ habitats |
Island Biogeography | Study of species on islands and isolated ecosystems |
Conservation Biogeography | Application of biogeography to protect species and ecosystems |
Examples:
- Why kangaroos are found only in Australia
- Why tropical rainforests have more biodiversity than deserts
- How continents breaking apart shaped animal evolution (e.g., Africa vs. South America)
Summary:
Biogeography = Bio (life) + Geography (earth)
It’s the study of life in space and time—why organisms are where they are and how they’ve changed over time.
