1/31/11 Population Growth Models: Logistic Growth Now lets study a population that is NOT under ideal conditions (limited resources) There is never such a thing as unlimited resources – so this model is closer to real life than exponential growth. Although some populations exhibit exponential growth in a novel environment early on. Carrying capacity – maximum

Unformatted text preview: 1/31/11 Logistic Model When a population is well below K it exhibits exponential growth, but as it approaches K population growth slows down. Maximum population size is K, then K-N tells us how many more individuals the environment can hold. And (K-N)/K tells us the fraction of K still available for population growth. SO therefore...
