Population Growth Models

• "exponential" growth model is one alternative
  • constant growth rate leads to increasing increments
  • J-curve
    • matter of scale of observation
    • Excel simulation of exponential growth and scale
• "Logistic" with a carrying capacity
  • growth rate decreases as population approaches the carrying capacity (i.e. maximum population)
• Minor adjustment - slight overshoot and correction
• Catastrophic decline
