Korpimaki and Norrdahl's research on voles (prey) and kestrels and owls (predators) suggest that the predator's population dynamics are
A) a functional response.
B) a numerical response.
C) in response to vole densities.
D) both a functional response and a numerical response.
E) both a numerical response and in response to vole densities.

Question

Korpimaki and Norrdahl's research indicates that the population dynamics of predators (kestrels and owls) are both a numerical response and in response to vole densities. This means that the number of predators and their distribution are influenced by the density of their prey (voles), showing both a change in predator numbers and a spatial or distributional response to prey availability.
