  1. Aim: SWBAT identify the three types of survivorship curves Please Do Now: EITHER finish that question on the back of the reading from yesterday OR 1) What has to be true for a population to grow exponentially? 2) What is carrying capacity?

  2. Agenda Do Now Lions vs. Buffalo Survivorship curve Deer population graphing

  3. How are different life histories represented graphically? • With survivorship curves • Graph time vs. proportion surviving • Three general types of curves • Type 1: high survival early in life, then big drop • Type 2: steady rate of deaths throughout life • Type 3: high mortality early, few individuals live a long time

  4. How do survivorship curves relate to r/K select species? • Type 1 roughly equals K select species • Type 3 roughly equals r select species
