Unformatted text preview: • At high prey densities, the predator population is limited by nest sites , and as a result, the predator’s density can never exceed 30predators/km 2 . • The prey population exhibits logistic growth in the absence of the predator. In the absence of the predator, the prey achieve an equilibrium of 100prey/km 2 . • At low predator densities (densities below the limit placed by nest sites), the predator has a per capita mortality rate of 0.10 d-1 . • A predator have a type one functional response. A predator achieves a feeding rate of 1 prey / day at a prey density of 20prey/km 2 . • A predator has to consume 10 prey before it can produce 1 new predator. • The prey have a per capita growth rate (r) of 0.5 d-1 at very low prey densities. Predator density Prey density 30 20 10 150 50 100...
