Next lesson. Practice: Population growth and regulation. Queensland and Western Australia responded by constructing rabbit proof fences to protect their agricultural interests. Although Fibonacci's assumption of the rabbits' immortality may seem a bit farfetched, his model was not unrealistic for reproduction in a predator-free environment: European rabbits were introduced to Australia in the mid 19th Century, a place with no real indigenous predators for them. The rabbits labelled with a Fibonacci number are the children of the original rabbit (0) at the top of the tree. Population Growth = (Births + Immigration) - (Deaths + Emigration) PG = (25 + 15) - (8 + 2) PG = +30 The overall effect on the population of finches in this example would be a net growth of 30 individuals. This requires students to identify which function parameters and key features. The trick is to develop a rabbit management plan that would ensure such a moderately sized population.
