The logistic growth equation provides a natural extension to the concept of exponential growth and is prevalent in both ecology and basic biology text books (Audesirk et al. 2010, Cain et al. 2008). In summary, exponential and logistic growth are two of the more fundamental concepts a student will learn in an ecology course.
