  • Taiga[1]

    1. 1. Taiga By: Heather McKee, Brandon Maddy, Ashleigh Khayo, Michael Teed, Rachell Wagers, Christina Steinmetz, and Omid Qayoumi .
    2. 2. Location <ul><li>Known as the Boreal Forest </li></ul><ul><li>The Taiga is located in the Northern Hemisphere. </li></ul><ul><li>Mostly in Canada </li></ul>
    3. 3. Location
    4. 4. Climate <ul><li>Winter ranges from -65 to 30 degrees F </li></ul><ul><li>Summer ranges from 30-70 degrees F </li></ul><ul><li>winter is longer and is colder due to the low angle of sunlight. </li></ul><ul><ul><li>Causes weaker light </li></ul></ul>
    5. 5. Precipitation <ul><li>Gets roughly 40 inches of rainfall each year </li></ul><ul><li>The further north in the Taiga the less precipitation </li></ul><ul><li>10-20 inches in the summer </li></ul><ul><ul><li>Three month growing season </li></ul></ul><ul><li>20-30 inches in the winter </li></ul><ul><ul><li>falls in the form of snow, so it is not useable to plants </li></ul></ul>
    6. 6. Coniferous Trees <ul><li>Most dominant plants in Taiga, that is why it is also called the coniferous forest </li></ul><ul><li>Due to the short growing season most conifers are evergreen (don’t shed their leaves) in order to be able to photosynthesize all year </li></ul>
    7. 7. Species of conifers <ul><li>Blue Spruce Scotch Pine Larch </li></ul><ul><li>Norway Spruce </li></ul>
    8. 8. Leaves <ul><li>Their leaves have a lower surface area in order to conserve water. </li></ul><ul><li>Their cuticle (waxy covering made of lipids/fats) is thicker to also prevent water loss </li></ul>
    9. 9. Conifers <ul><li>Myccorhizae </li></ul><ul><ul><li>A fungus that grows on the roots to absorb water for the tree and in return the conifer provides glucose for the fungus. This is an example of mutualism. </li></ul></ul>
    10. 10. Fire! <ul><li>Is a necessary adaptation that assists in the reproduction of certain species of conifers. </li></ul><ul><li>The heat has to burn the resin from their cones in order to open the scales to receive pollen </li></ul>
    11. 11. Animal Adaptations <ul><ul><li>Food Cache </li></ul></ul><ul><ul><li>Storage site for certain animals’ food. </li></ul></ul><ul><ul><li>Usually hidden </li></ul></ul><ul><ul><ul><li>Ex. A squirrel storing acorns in the ground </li></ul></ul></ul>
    12. 12. Elk/Moose <ul><li>Large herbivores whose height allows them to reach high vegetation </li></ul>
    13. 13. Lynx <ul><li>Insulation </li></ul><ul><ul><li>thicker amounts of fur keep the cat warm during the harsh winters </li></ul></ul>
    14. 14. Boreal Porcupine <ul><li>Burrows into the snow to hide from the winds and the cold during the winter months </li></ul>
    15. 15. Snowshoe Hare <ul><li>Large pads on feet allow for running across snow (like snowshoes) </li></ul><ul><li>Grows a brown coat in order to camouflage during the summer months, and then grows a white one in the colder months </li></ul>
    16. 16. Foxes/Wolves <ul><li>Have a thick coat to protect against the elements </li></ul><ul><li>Burrows into the snow to avoid the cold and the wind </li></ul><ul><li>Larger pads then its more southern ancestors in order to run on the snowy terrain </li></ul>
    17. 17. Saw-whet Owl <ul><li>Migrates south for some of the colder months to avoid the cold </li></ul><ul><li>Nest in holes left by woodpeckers during the warmer months </li></ul>
    18. 18. Hibernation <ul><li>Hibernation is the resting period for some species of animals. During this, their metabolism, temperature, and breathing rate slows. </li></ul><ul><li>They hibernate because there isn’t enough food to sustain the population. </li></ul>
