Biogeography EE 2.5 What Factors Affect species dispersal?
Biogeography • The study of where organisms live and how they got there
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?
Means of Dispersal • Dispersal: The movement of organisms from one place to another. Wind ~ Water ~ Other living things
Limits of Dispersal • Physical Barriers: can limit the movement
Limits of Dispersal • Competition: must compete for resources with species that already live there
Limits of Dispersal • Climate: Some species cant live in certain climates
