A Population of Blowflies Experiences Logistic Growth with Delayed Density

question 16

Multiple Choice

A population of blowflies experiences logistic growth with delayed density dependence. Suppose that this population has an initial size of 4,295 and follows the standard equation for delayed density dependence with a 10-week delay and an intrinsic growth rate of 0.2 per week. If these conditions remain constant and the population is tracked for a long time, what type of population dynamics should it display? (Note: The cutoff r value for dampened oscillations is 0.368, and the cutoff for a stable limit cycle is 1.57.)

• A) A stable limit cycle
• B) Logistic growth
• C) Dampened oscillations
• D) Exponential growth
