This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants.

This film explores the evolutionary connection between an infectious disease, malaria, and a genetic condition, sickle cell disease.

This video follows an international team of researchers as they collect data to map migratory bird populations in the US and Mexico.

In this activity, students use an interactive tool to simulate how scientists collected and used sample data to estimate elephant population sizes.

This interactive video explores how two scientists tracked the 2013 Ebola outbreak in West Africa. 

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.

In this video, ecologist Tony Sinclair takes us through the steps of how he uncovered that the eradication of an infectious disease in cattle led to a boom in the Serengeti’s buffalo and wildebeest numbers.

This video follows biologist Shane Campbell-Staton, who is studying the adaptations that allow deer mice living at high elevations to stay warm and active during the winter.

This film explores the foundational research in the Serengeti National Park, Tanzania, that uncovered many of the ecological principles that govern how animal populations and communities are regulated.

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

This short video explores how bacteria have evolved mechanisms to resist antibiotics.

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