IB Geography - Ecosystems. Biomes - Taiga aka Coniferous forest

  1. 1. Biome presentation Coniferous forest – Taiga
  2. 2. Location <ul><li>Located in: </li></ul><ul><li>North America </li></ul><ul><li>Scandinavia </li></ul><ul><li>Russia </li></ul><ul><li>Across Asia: Siberia and Mongolia </li></ul><ul><li>Northern China </li></ul><ul><li>Northern Japan </li></ul>
  3. 3. Climate in Taiga <ul><li>Sub arctic & cold continental climate </li></ul><ul><li>Cold winds bring bitterly cold air from the Arctic Circle </li></ul><ul><li>Tilted Earth – taiga is turned away from the sun in winter </li></ul>
  4. 4. Winter <ul><li>Lasts for 6 months </li></ul><ul><li>Cold & severe </li></ul><ul><li>Temperature –30 °C </li></ul><ul><li>Some snowfall </li></ul><ul><li>Lasts for 3 months </li></ul><ul><li>Hot & humid </li></ul><ul><li>Temperature 30 °C </li></ul><ul><li>A lot of rain </li></ul>Summer
  5. 5. Temperature <ul><li>Highest temperatures in July & August (30 °C) </li></ul><ul><li>Lowest in January & February (–30 °C) </li></ul><ul><li>Most rainfall from June to August </li></ul><ul><li>Most snow from December-February </li></ul>Precipitation
  6. 6. Vegetation <ul><li>NPP – 800g/m2/yr </li></ul><ul><li>Nutrient cycle: </li></ul><ul><li>Litter – the largest </li></ul><ul><li>Biomass – medium </li></ul><ul><li>Soil – the smallest </li></ul>Nutrient cycle
  7. 7. Vegetation <ul><li>Very few species </li></ul><ul><li>Needle leaf trees are dominant & adapted to the cold </li></ul><ul><li>Coniferous trees can keep they’re needles for 15 years </li></ul><ul><li>Advantages </li></ul><ul><li>Needle leaf – have thick waxy coatings </li></ul><ul><li>Conical shape – prevents loss of branches </li></ul><ul><li>Evergreen habit – plants can photosynthesize throughout the year </li></ul><ul><li>Dark green color – helps to begin the photosynthesis early </li></ul>
  8. 8. Vegetation Mosses Lichen
  9. 9. 4 main needle leaf trees in Taiga Fir Spruce
  10. 10. 4 main needle leaf trees in Taiga Pine Larch
  11. 11. 4 main leaf trees in Taiga Aspen Birch
  12. 12. 4 main leaf trees in Taiga Willow Rowan
  13. 13. Soil <ul><li>Type of soil – podzolic </li></ul><ul><li>Very acidic & sandy </li></ul><ul><li>Poor in nutrients </li></ul><ul><li>Poor agricultural soil </li></ul><ul><li>Leached minerals –restricts the drainage of water through the soil </li></ul>
  14. 14. Animals in Taiga <ul><li>Need to have special adaptations to survive </li></ul><ul><li>Adapted to the climate by hibernation </li></ul><ul><li>Breed and raise the young in the summer </li></ul><ul><li>Constantly changing population – local animals have to change what they are hunting </li></ul>Food Chain
  15. 15. Animals in Taiga <ul><li>The bear – omnivore. </li></ul><ul><li>Eats berries and salmon in the summer </li></ul><ul><li>Needs to &quot;fatten up&quot; for winter hibernation. </li></ul><ul><li>Winter – the bear goes to its cave & sleeps until the spring </li></ul>
  16. 16. Animals in Taiga <ul><li>Lynx – carnivore </li></ul><ul><li>Eats rabbits, birds, and other small prey. </li></ul><ul><li>Adapts by changing its coat to disguise itself. </li></ul><ul><li>Soft white in the winter </li></ul><ul><li>Light brown with dark spots in the summer </li></ul>
  17. 17. Animals in Taiga <ul><li>Snowshoe Rabbit – herbivore </li></ul><ul><li>Eats available plants </li></ul><ul><li>Has large back feet – snowshoes. </li></ul><ul><li>Grayish brown fur in the summer </li></ul><ul><li>Pure white in the winter </li></ul><ul><li>Can run up to 40km/h and jump 90cm in one hop. </li></ul><ul><li>An expert at escaping predators like the wolf or lynx. </li></ul><ul><li>Good swimmers – will swim to make an escape. </li></ul>
  18. 18. Conclusion <ul><li>Largest biome </li></ul><ul><li>Cold & sever winters </li></ul><ul><li>Hot & humid summers </li></ul><ul><li>Dominating needle leaf trees </li></ul><ul><li>Poor soil </li></ul><ul><li>Few species </li></ul><ul><li>Animals need special adaptations to survive </li></ul>
