PREDATION III CO-EVOLUTION
I. “Prudent Predators”
“Predators act to maximize their return without threatening the stability of the prey
system”
A. Fisheries and other human harvesting of wild populations
1) Maximum sustainable yield
2) Other models of sustainable exploitation.
B. Natural predators – are they “prudent”?
1) What would be required?
2) How would it evolve?
3) Do we see this in nature?
II. What can predators do? – plasticity
A. Prey choice – electivity
B. Switching
C. morphological adaptations
III. What can Prey do?
A. Inducible defenses
B. Behavioral modifications
IV Community level effects
A. 2 and 3 (odd and even) level systems
B. Top down control
C. Higher order interactions
