  1. S=cAz
    • S= Number of species
    • A= Area (of an island)
    • C/z= constants. Vary for each study

    log(S)= log(c) + zlog(A)
  2. More isolated islands=
    bigger z value
  3. Larger Area=
    • More species because of variations in disturbance, climate, and habitat
    • Greater populations= less prone to extinction
  4. Top Left, Bottom Left, Top Right, Bottom Right of equilibrium model of island biogeography
    • (Immigration)Near, Far
    • (Extinction) Small, Large
