How are different life histories represented graphically

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


How do survivorship curves relate to r k select species

How do survivorship curves relate to r/K select species?

  • Type 1 roughly equals K select species

  • Type 3 roughly equals r select species
