The capacity for growth is a measure of a species population’s success. Because there are so many interactions between individuals and the environment, measuring how well populations grow is often complex. Population biologists frequently use mathematical growth models to help them study real populations.
Population models might seem like all theory and math, but they help us understand real ecological systems in simpler terms. They are used for testing theories, making predictions, and for making decisions about managing or conserving populations of many species.
In this activity, you will learn about two widely used population growth models (Exponential and Logistic) and how they can be applied to natural populations.
Graphical representation of the two simplest models of population growth: Exponential growth and Logistic growth. These two population growth models will be covered in this activity.
For this activity, you should:
- Review the lecture notes on Population Growth
- Have a calculator for some calculations
