Which of the following is an example of delayed density dependence?
I. The per capita growth rate of a coyote population decreases as the number of coyotes increases.
II. The fecundity of two-year-old frogs is based on their density as tadpoles.
III. The number of seeds produced by flowers in the fall depends on the amount of rainfall the previous spring.

Question

Quizplus · Accepted Answer

Delayed density dependence occurs when current population density affects future population density. Option II shows an example of delayed density dependence, as the density of tadpoles affects the fecundity of two-year-old frogs in the future. Option I shows density dependence but not delayed density dependence, while option III shows density independence.
