Suppose two populations of Anolis lizards are of equal size at the beginning of an experiment. One population (the experimental group) is exposed to a predator (16 predatory lizards), and the other (the control) is not. The final size of the experimental population is 50, and the final size of the control population is 200. What is the per capita interaction strength of predatory lizards on Anolis lizards

June Kline · Answer 1

Per capita interaction strength is - 0.046875.

Explanation:

N=50, D=200, Y=16, interaction strength is estimated as (N-D) / (DY)

(50-200) / (200*16) = - 0.046875
