Simulation of Individual Variatio

Slide 21 of 47

To illustrate individual variation, start with the basic demographic variation model developed above. Instead of each animal having exactly a birth rate of 0.5 and a death rate of 0.5, lets select these values from beta distributions with a mean of 0.5. The birth and death rates assigned to an animal remain for its life time. As new animals are added to the population, they likewise are assigned life-time birth and death rates. How does persistence of this new model compare with the results from the demographic model?
