1. The Typhlodromus mite exhibited four attributes which are characteristic of predators that can control their prey. What were they?

2. On page 303, Ricklefs discussed environmental "patches." What are the suitable habitat patches of the Cactoblastis moth?

3. After considerable experimentation, what did C. B. Huffaker discover was the key to establishing a stable cycle in his predator-prey system?

4. In Fig 20.12 on page 463, Ricklefs shows that a predator exhibiting a Type II functional response eats an increasing number of prey as prey density rises, but the rate of prey consumption declines. How are these two patterns consistent with one another? What does "rate of prey consumption" mean?
