Polar region Notes on various Polar ecosystems including Arctic, Antarctic, Tundra, & Taiga, mentioning global warming & climate change with video links

  1. 1. Polar Region POLAR link PPt. by, Robin D. Seamon
  2. 2. <ul><li>Arctic: (N Pole) </li></ul><ul><li>Antarctica: (South Pole) COLDER than N. Pole; ground is always frozen, covered in snow & ice </li></ul><ul><li>At the poles (N. Pole is magnetic!) </li></ul><ul><li>Months of daylight in summer; months of night in the winter due to the earth’s tilt </li></ul>
  3. 3. <ul><li>Polar ice caps high frozen, latitude region </li></ul><ul><li>Glaciers: rivers of frozen water </li></ul><ul><li>Icebergs: frozen chunks of fresh water in the ocean; much deeper under the water </li></ul><ul><li>Permafrost: permanently frozen ground </li></ul><ul><li>Global warming is melting the ice! </li></ul>
  4. 5. http://express.howstuffworks.com/gif/wq-iceberg-underwater.jpg
  5. 6. Where are the POLAR REGIONS?
  6. 7. NO PLANTS IN THE POLAR REGIONS
  7. 8. ANIMALS in the Polar Regions: <ul><li>Polar bears, walrus, seal: Arctic </li></ul><ul><li>Penguins, seal: Antarctica </li></ul>
  8. 9. Polar Region TESTING THE SNOW video (Man vs. Wild) Building an IGLOO (Man vs. Wild)
  9. 10. TUNDRA
  10. 11. <ul><li>Tundra: vast, treeless land in the Arctic Region at North Pole; </li></ul><ul><li>A COLD desert! </li></ul><ul><li>average temperature is -70 °F; very windy </li></ul><ul><li>Ground is frozen 10 inches to 3 feet </li></ul><ul><li>Months of night time in the Winter, months of daylight in the summer </li></ul>
  11. 12. WHERE are TUNDRAS? N. American Tundra, Scandinavian Tundra, Russian Tundra (Siberia)
  12. 13. <ul><li>PLANTS in the TUNDRA: the growing season is only 50-60 days long! </li></ul><ul><li>Shrubs </li></ul><ul><li>Sedges </li></ul><ul><li>Mosses </li></ul><ul><li>Lichens </li></ul><ul><li>Grasses </li></ul>
  13. 14. <ul><li>ANIMALS in the TUNDRA: </li></ul><ul><li>Caribou, musk oxen, wolverines, polar bears, snowshoe rabbits, </li></ul><ul><li>Migratory birds: pipers, plovers, harlequin ducks </li></ul><ul><li>FACT: tundra mosquitos replace water in bodies with glycerol so as not to freeze! </li></ul>

  15. 16. <ul><li>ENVIRONMENTAL NOTES: FRAGILE ECOSYSTEM!!! </li></ul><ul><li>Biomass sinks : takes in more carbon dioxide than it puts out </li></ul><ul><li>Plants freeze & can’t decompose, therefore millions of years old plant material is frozen in the permafrost. </li></ul><ul><li>PROBLEM: Global Warming is melting the permafrost, releasing the carbon dioxide! … greenhouse gas ! </li></ul>
  16. 17. <ul><li>People are going there to mine & drill for oil </li></ul><ul><li>Alaskan pipeline runs across a caribou migration route </li></ul><ul><li>Roads/ towns built for miners & drillers </li></ul><ul><li>Animals’ feeding patterns are disrupted; many polar bears (top of food chain predator) starve </li></ul>
  17. 18. <ul><li>Pesticides are sprayed for insects but also harm the migratory birds </li></ul><ul><li>Pollution from the mines is harming the air, land & water in the fragile tundra environment </li></ul><ul><li>Man… erosion </li></ul>SURVIVAL in the Snow
  18. 19. TAIGA http://www.alaska-in-pictures.com/denali-fall-foliage-taiga-1393-pictures.htm http://www.cas.vanderbilt.edu/bioimages/ecoregions/50607.htm
  19. 20. <ul><li>TAIGA : Russian word for “forest” </li></ul><ul><li>needle-leaf forest in the North ( boreal forest ) </li></ul><ul><li>-65 ° F (winter) to 70 ° F (summer) </li></ul><ul><li>Coldness & food shortages </li></ul><ul><li>Cold, snowy winters </li></ul><ul><li>Warm, humid summers </li></ul>
  20. 21. Where is the TAIGA? N. America, Europe, Asia
  21. 22. <ul><li>ANIMALS in the Taiga: </li></ul><ul><li>Many hibernate during the winter </li></ul><ul><li>Some migrate south in winter </li></ul><ul><li>Millions of insects in the summer </li></ul><ul><li>Birds migrate there for insects in the summer </li></ul><ul><li>Lynx, wolverine, bobcat, snowshoe rabbit, squirrel, red deer, moose, elk </li></ul>
  22. 23. Surviving the Rapids: Man vs. Wild
  23. 24. <ul><li>PLANTS in the TAIGA: </li></ul><ul><li>Evergreen trees (conifers) </li></ul><ul><li>Wildfires: thick tree bark </li></ul>
  24. 25. POLAR REGION
  25. 26. TUNDRA: Vegetation: lichens , mosses, sedges , perennial forbs , and dwarfed shrubs , (often heaths , but also birches and willows). Herbivores: musk oxen, pikas, arctic hares, caribou, lemming, Primary carnivore: arctic fox, bear Secondary carnivore: arctic wolves, snowy owls,
