Mortal Fibonacci Rabbits
Consider an idealized biological system consisting of mortal rabbits with some fixed initial number of baby rabbit pairs. After the rabbits become mature each pair begets a new pair every month. Use the controls to explore how the rabbits' life span, age of fertility, and initial number of pairs affect the population growth.
One generation after the first rabbits have occupied the ecosystem, the population satisfies , where is the age of fertility and is the lifespan.
