Presentation Transcript

  1. Biogeography EE 2.5 What Factors Affect species dispersal?

  2. Biogeography • The study of where organisms live and how they got there

  3. Biogeography: Continental Drift The movement of Earth’s continents is one factor that affects how species are distributed. Could some species from Africa reach South America?

  4. Means of Dispersal • Dispersal: The movement of organisms from one place to another. Wind ~ Water ~ Other living things

  5. Limits of Dispersal • Physical Barriers: can limit the movement

  6. Limits of Dispersal • Competition: must compete for resources with species that already live there

  7. Limits of Dispersal • Climate: Some species cant live in certain climates
