  1. Biogeography Prepared by: Lorienne A. de Asis Sittie Alyssa B. Mamailao

  2. What is Biogeography? • It is the study of the distribution of species,organisms, and ecosystems in geographic space and through geological time. 

  3. History of Biogeography Alfred Russel Wallace • Popularly studied Biogeography • was a naturalist, explorer, geographer, anthropologist, and biologist.  • Wallace is often called the "Father of Biogeography."

  4. Types of Biogeography • Historical biogeography • Ecological biogeography • Conservation biogeography

  5. Types of Biogeography Historical Biogeography • is called paleobiogeography and studies the past distributions of species.  • It looks at their evolutionary history and things like past climate change to determine why a certain species may have developed in a particular area.

  6. Types of Biogeography Ecological Biogeography •  looks at the current factors responsible for the distribution of plants and animals. • The most common fields of research within ecological biogeography are climatic equability, primary productivity, and habitat heterogeneity.

  7. Ecological Biogeography Climatic equability • looks at the variation between daily and annual temperatures.  Primary productivity • looks at the evapotranspiration rates of plants. Habitat heterogeneity • leads to the presence of more biodiversity (a greater number of species present).

  8. Types of Biogeography Conservation Biogeography • This is the protection and/or restoration of nature and its flora and fauna.

  9. Fundamental Concepts of Biogeography • Evolution • Extinction • Dispersal • Range and distribution • Endemism

  10. Fundamental Concepts of Biogeography Evolution • is the change in the inherited characteristics  of biological populations over successive  generations. • change in genetic composition of a population

  11. Fundamental Concepts of Biogeography Extinction • In biology and ecology, it is the end of an organism or of a group of organisms (taxon), normally a species.  • disappearance of a species

  12. Fundamental Concepts of Biogeography Dispersal • refers to species movement away from an existing population or away from the parent organism. • movement of populations away from their point of origin, related to migration.

  13. Fundamental Concepts of Biogeography Endemism •  is the ecological state of being unique to a defined geographic location, such as an island, nation or other defined zone, or habitat type.

  14. Fundamental Concepts of Biogeography Range and distribution • is the geographical area within which that species can be found.
