Logistic population growth is rare in nature

WitrynaMain concern of population ecology is growth (or decay) and interaction rates of the entire population. Study of population change started with F.Fibonacci, the greatest European mathematician of the middle ages, who introduced a mathematical model for a growing rabbit population in his arithmetic book [2]. If population is defined as a WitrynaThe most relevant basic population growth model for understanding the various approaches to harvesting is called the logistic growth model.
