8. Primary vs. Secondary Clip http://www.geowords.org/ensci/imagesbook/ 04_03_succession.swf

9. Primary Succession A community is established in a fairly lifeless area First life forms are usually bacteria, then lichens Soil eventually develops, then plants are established

10. Example of primary succession A retreating glacier leaves a moraine, a soil-laden area where life has the potential to take root.

11. Secondary Succession Occurs in an area where disturbance has occurred, but the soil is intact – After a forest fire – After a hurricane

12. Example of secondary succession

13. Are pioneer species r or k species?

14. R vs K species R species -breeding at a young age -a short lifespan -producing many offspring quickly -small offspring -high mortality rates of young -nonexistent parental care. K species -long maturation time -breeding relatively late in life -a long lifespan -producing relatively few offspring -large newborn offspring -low mortality rates of young, -extensive parental care.parental care Examples of a K-selected species include elephants, bonobo apes and humans. Examples of r-selected species include waterfleas, insects, and bacteria.

16. Make graphs for r vs. k species
