  • Biomes
    • Tundra
      • Surrounds North and South pole
        • Latitude - From Arctic circle to 60'-70' north
          • Located: Alaska, North Canada, parts of Greenland, North Scandinavia, North Siberia and Russia
      • Average temp: -34' in winter, 12' in summer
        • Precipitation: 15cm-25cm annually - includes melting snow
          • Long winter season and short, mild summer season
      • Arctic moss - long life, slow growth for slow growing season and cold
      • Polar bears, white wolves. Migration and Hibernation
    • Coniferous Forests (Boreal)
      • Scandinavia, Russia, Canada
        • Latitude: 50'-60' N
      • Average temp: 10'C summer, -30'C winter
        • Precipitation: 300mm-900mm annually - mainly snow
          • Long cold winters and short warm, moist summers
      • Mountain Ash - hanging bark - allows fire to travel up from forest floor to canopy
      • Sable, Marten - thick fur coats for mammals.
    • Temperate Deciduous Woodlands
      • 40'-60' N & S
        • North west Europe, North America, parts of East Asia
      • Average temp: 0'C  - winter, 20'C-25'C summer
        • Precipitation: 500mm-1500mm annually
      • Blue bells - flower early in year before leaves of trees above grow again and block out light.
      • Broad-winged hawks, Cardinals - able to cope cold winters and hot summers. Some migrate/hibernate to avoid cold.
    • Temperate Grasslands
      • Puszta in Hungary, Velolt in South Africa, Pampas in Argentina and Praries in USA
      • Average Temp: 38'C summer, -40'C winter
        • Precipitation: 10 inches-35 inches annually
          • Hot summers and cold winters
      • Purple needle grass - deep roots, narrow leaves
      • Animals have broad, flat topped teeth and digestive systems adapted to feed on grass.
    • Mediterranean
      • Located on west coast of continents between latitude 30' and 40'. Parts of Europe, North Africa and Asia - coastal areas surrounding Mediterranean Sea
      • Precipitation: 900mm annually - winter
        • Temp: 22'C summer, 18'C--3'C winter.
          • Hot dry summers and mild/cool winters - wet.
      • Conserve water and survive summer droughts - plants
      • Able to survive hot, dry summers
    • Hot Desert
      • Located in North Africa, North America, South America, South Asia and Australia
      • Temp: max - 43.5'-49'C, min - -18'C
        • Precipitation: 25cm annually - rain or snow
          • Warm autumn ans springs,  very hot summers
      • Plants store water in fleshy leaves, stem or roots
        • Animals able to deal with scarce water and extreme temperature
    • Tropical Grasslands (Savanna)
      • Central Africa, South America, India and Australia. Latitude - 15'N and 30'S
      • Temp: 18'C, Precipitation - 20inches- 25inches. Wet summers and long, dry winters
      • Plants - long tap roots - reach deep water table, thick bark - resistance to annual fires, deciduousness to avoid moisture loss. Use of tree trunk as water storage organ.
      • Animals adapted to living with fires. Migrate to other biomes till rainy season ends.
    • Tropical Rainforests
      • Amazon River Basin, South America, Congo river Basin, west Africa, South east Asia, Central America,  Madagascar, Australia, India and other locations in tropics. Equator, Tropics of Cancer and Capricorn
      • Constant temp: 28'C - 2' change max. Precipitation - Daily - 2100mm annually. 1 long wet season and 1 shorter, drier season
      • Plants - drip tip leaves so raindrops run off quickly. Avoid bacteria growth and fungi in warm, wet tropical weather.
        • Some animals never set foot on ground. Use tall trees and understory for shelter, hiding and food.
