Lionfish Invasion: Density-Dependent Population Dynamics

In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.

Teaching Population Dynamics and Trophic Cascades Using Large Mammals

This playlist can be used to teach several core concepts of population dynamics and trophic cascades through three diverse ecological examples: wolves in Isle Royale, Michigan; rinderpest and wildebeest in Tanzania; and cougars in Zion National Park, Utah. It can be used in general biology and environmental high school courses.
