TRANSCRIPT

  • Intraspecific Competition Goals (part 1): • Understand steady-states • Understand density dependent population

    regulation • Be familiar with the logistic equation • Assumptions of logistic model • Be familiar with examples of logistic growth

  • Intraspecific Competition Goals (part 2): • How are time lags incorporated into the

    logistic model? • Qualitatively describe how time lags affect

    population growth with the logistic model • Discrete vs. continuous form of the logistic

    model – built in time lags • How do populations with different r respond

    to variations in carrying capacity?

  • Logistic Equation – Sigmoid Growth

  • Logistic

    Exponential Exponential

    Logistic

    These figures compare dN/dt and [(1/N)(dN/dt)] for the logistic and exponential models. They might help you to conceptually understand the difference between the two with respect to population growth and the intrinsic rate of growth as population size changes.
