Factors Affecting Distribution:

  • Climate
  • Adiabatic lapse rate - 1 degrees lost for every 200m
  • Closer you are to the sea the wetter the climate
  • Soil - nutrient rich = more biodiversity
  • Isolation - reduces number of species but increases endemism eg. Hawaii
  • History & age - biodiversity is greatest in oldest and least disturbed ecosystems especially in Tropics
  • Size of an area - large continuous biomes support wider range of species and encourage migration


  • Size of an area - biodiversity increases with area because large continuous biomes support a wider range of biodiversity and large boundaries encourage migration
  • History & age…
