Population Dynamics and Growth Rates

This lesson explores logistic growth, focusing on overshoot and collapse phenomena. It begins with an introduction to logistic growth and carrying capacity, followed by examples illustrating overshoot and population dynamics. The lesson discusses how high growth rates can lead to overshoot, where the population exceeds carrying capacity, and examines the two cycle phenomenon. It concludes with a discussion on extreme behaviors, such as stable cycles and population collapse, emphasizing the importance of understanding these dynamics in nature.

What is the term used when a population exceeds its carrying capacity?

• Overshoot
