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.

This interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.

This interactive module explores methods used to survey large animal populations, and what they have revealed about the current state of the African elephant population.

This interactive module explores how the process of eukaryotic gene expression is regulated, using the production of the enzyme lactase as an example.

This tutorial describes three examples of recent human adaptations: lactose tolerance, sickle cell disease, and bitter taste perception.
