Ecological succession 2010

  1. 1. Ecological Succession<br />
  2. 2. Gradual development of a community over time following predictable stages<br />Primary or secondary<br />
  3. 3. Primary Succession<br />Begins in a place without any soil <br />Arrival of PIONEER SPECIES<br />lichens, etc. do not need soil to survive<br />http://botit.botany.wisc.edu<br />http://www.saguaro-juniper.com/<br />
  4. 4. Soil forms <br />Weathering and erosion break down rocks, decomposition or organic material<br />http://www.life.uiuc.edu<br />
  5. 5. Simple plants grow<br />Mosses then later ferns<br />http://uisstc.georgetown.edu<br />http://www.uncw.edu<br />

  9. 9.
  10. 10. Secondary Succession<br />In a place that has soil & living organisms <br />Example: after forest fires<br />Faster <br />Different pioneer species<br />

  14. 14. Climax Community<br />End result of succession<br />Stable group of plants and animals<br />Not necessarily big trees<br />Ex: gasses in prairies, cacti in deserts<br />
  15. 15. Sequencing Succession<br />Put the pictures on your desk in order from the beginning to the end of the succession sequence<br />Decide if it is primary or secondary succession<br />Explain the process<br />
  16. 16. Compare and contrast Primary and Secondary succession<br />What are the conditions?<br />How long does it take?<br />What does it start with?<br />What are the pioneers?<br />
