BI308 Chapter Notes - Chapter 5: Frequency-Dependent Selection, Ideal Free Distribution, Decision Rule
Document Summary
Bi308 chapter 5 notes competing for resources. Demonstrates the changes in fitness resulting from a contest. Value of winning the contest is the difference between the reproductive success in the good and poor habitats. The best ess is always the one in which one case something is rare because frequency dependent selection and equilibrium will occur. Ideal free distribution no limit to the number of competitors that can exploit the resource. Every individual is free to choose where to go. The first arrivals will go to the rich habitat. Because of resource depletion, the more competitors that lower the rewards per individual so at point a (optimum between rewards per individual and the rich habitat) the poor habitat will be equally attractive. Thereafter, the two habitats should both be filled so that the rewards per individual are the same in each.
