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 video shows how a group of students, scientists, and volunteers came together to make hand sanitizer and masks for their community during the COVID-19 pandemic.

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 case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

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 explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans.

This video describes a large-scale project to restore the wildlife of Gorongosa National Park. The video highlights the project’s approach of combining traditional conservation biology with solutions for addressing challenges in the community.

This interactive module explores niche partitioning, a mechanism that enables similar species of animals to coexist.

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