  1. Introduction to Ecology 10/12/2012

  2. Goals for the day • Understand, and be able to describe the difference between r-strategists and K-strategists. • Be able to draw the exponential & logistic growth curves labeling the X & Y axes (and carrying capacity where necessary) • Be able to say how ozone depletion is involved in skin cancer.

  3. Question of the day Draw & Label an Exponential Growth Curve & a Logistic Growth Curve. What is the main thing that separates them?

  4. Question of the day Draw & Label an Exponential Growth Curve & a Logistic Growth Curve. What is the main thing that separates them?

  5. OzoneLayer- absorbs harmful UV radiation from the sun. What have you heard about the ozone layer?

  6. OzoneLayer- absorbs harmful UV radiation from the sun. Depletion ( ) - first noticed in the late 1970s, ozone depletion has been caused by a build up of Chloroflorocarbons (CFCs) in the upper atmosphere (Stratosphere).

  7. Ozone Layer Depletion • In 1987 the MONTREAL PROTOCOL, a UN Treaty was signed by 24 countries. This protocol banned the use of CFCs to prevent further damage to the ozone layer.

  8. CFCs have are a long lived gas in the atmosphere, but due to the Montreal Protocol, which 197 countries have now signed, CFCs are starting to dissipate ( ) and the Ozone layer is starting to heal

  9. Depletion (Decrease ) of ozone in the atmosphere has been implicated (linked/accused ) in the cause of skin cancer. WHY? Due to increased amounts of UV radiation from the sun.

  10. Field Guide Page • You will CREATE 2 organisms • One will be a K strategist, AND one will be an r strategist • Each organism will have its own field guide page with the following attributes
