Desert Project[1]

  1. 1. DESERT BIOME  By: Tori Ahr, Amanda Dirr, Kelli James, Romisha Law, Sarah Mossman and Sara Moster NORTH AMERICAN:
  2. 2. LOCATION <ul><li>They are in the Rain Shadow of the Rocky Mountains. </li></ul><ul><li>LOWER Oregon and Idaho: Nevada, Utah, California, Arizona, New Mexico and Mexico </li></ul><ul><li>The size of the mountains block any precipitation coming from the coast. </li></ul>
  3. 3. CLIMATIC CONDITIONS <ul><li>Annual Precipitation: </li></ul><ul><ul><li>9.84-11.02 in. a year </li></ul></ul><ul><ul><li>May and June are the driest months </li></ul></ul><ul><ul><li>November to August are the wettest months </li></ul></ul><ul><li>Annual Temperature: </li></ul><ul><ul><li>Temps. Range from -.4°F to 120°F </li></ul></ul><ul><ul><li>Average temperature is around 75°F </li></ul></ul><ul><li>The temperature tends to range and it is not always extremely hot. </li></ul><ul><li>The temperature drops at night, and plants and animals have to adjust. </li></ul>
  4. 4. Desert Plants <ul><li>Mostly ground-hugging shrubs and short wood trees with wide roots because of the lack of water </li></ul><ul><li>Dominant Plants include: Cacti, Brittlebush, Pancake Prickly Pears, Desert Ironwood, Joshua Tree, Palo Verde & Triangle-Leaf Bursage. </li></ul><ul><li>Vegetation is not yet layered to maximize moisture consumption </li></ul>Palo Verde
  5. 5. Cacti Adaptations <ul><li>The leaves adapt into needles because they don’t have enough water & energy. The spiny needle is actually the Midrib of the well-known leaf (the line that goes through the leaf). </li></ul><ul><li>Chloroplasts are in the stem and the cacti must grow slow because there is not a lot of water. </li></ul><ul><li>All cacti flower but only after rain comes, during this time the cacti plant also grows. </li></ul>
  6. 6. more plant adaptations… <ul><li>The pores (in plants) during the day close to prevent water loss </li></ul><ul><li>Complicated root systems extend many miles and may be located towards the top of the surface to directly collect rain </li></ul><ul><li>Silver and glossy leaves reflect more energy that is radiant and affects the taste </li></ul>
  7. 7. SOiL <ul><li>Dry and poor </li></ul><ul><ul><li>Thin </li></ul></ul><ul><ul><li>With little nutrients </li></ul></ul><ul><li>Composed of Sand and Gravel </li></ul><ul><ul><li>Does not hold water </li></ul></ul>
  8. 8. ANiMALS <ul><li>Fossorial-which means ‘to borrow’ which they do to escape the heat </li></ul><ul><ul><li>Rabbits </li></ul></ul><ul><ul><li>Skunks </li></ul></ul><ul><ul><li>Burrowing Owls </li></ul></ul><ul><ul><ul><li>They take over burrows because they are not able to dig their own. They escape predation and they make noises similar to rattle snakes to scare off predators. </li></ul></ul></ul>
  9. 9. More animals… <ul><li>Nocturnal </li></ul><ul><ul><li>Animals come out during the night to escape the heat </li></ul></ul><ul><li>Crepuscular </li></ul><ul><ul><li>They come out at dusk and dawn; to escape the heat </li></ul></ul>
  10. 10. Animal Adaptations <ul><li>Their bodies are equip to store amounts of water and cope with food shortages </li></ul><ul><li>Most animals are small and only get water from the food that they eat </li></ul>
  11. 11. Other Biome.. <ul><li>Phoenix </li></ul><ul><li>Tusan </li></ul><ul><li>Las Vegas </li></ul><ul><li>Many people are flooding into these places. </li></ul>
