  • Biodiversity
    • Altitude
      • Higher altitude = lower biodiversity
    • Latitude
      • Lower latitudes = warmer climate = rapid nutrient cycling
    • Temperature
      • Extreme temperatures = low biodiversity
    • Light intensity
      • Gross Primary Productivity is the rate at which photo-synthesis is measured
        • The Rain Forest has high GPP = higher biodiversity
    • The rate of the nutrient cycle
    • Endemism
      • Found particularly on islands, species that are found nowhere else and this increases biodiversity
    • Human effects e.g. pollution
      • Humans are in competition with other species for space and resources. As human population increases = decrease in biodiversity
    • The level of recording of species within the region
    • Hunting and direct exploitation of flora and fauna
