Lionfish Invasion: Density-Dependent Population Dynamics

About

In this Click & Learn, you’ll explore how to use mathematical population models to study invasive lionfish. Next, you’ll examine scientific case studies to learn more about factors that can slow the growth of populations when they get large.

In some parts of the ocean, lionfish are an invasive species. Lionfish populations can be modeled using a logistic model, which describes how a population changes if there is an upper limit to its size. This model can be applied to populations that are limited by food, space, competition, and other density-dependent factors.
