This film explores the species-area relationship, a general ecological rule that describes how the number of species in a habitat changes with area, and shows how it has been applied to the conservation of protected areas.

This video focuses on the front lines of the 2013–2016 Ebola outbreak in West Africa and explains how scientists monitored the evolution of the virus by analyzing its genome.

This video describes the process by which a line of genetically modified mosquitoes was engineered to reduce populations of wild mosquitoes.

This film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.

This video showcases the work of mathematician-turned-biologist Corina Tarnita, who uses quantitative approaches to understand the role of termite mounds in the savanna ecosystem.

This film describes the scientific principles and the research efforts involved in the development of a gene therapy for a congenital form of blindness, and how a young patient benefited from this medical breakthrough.

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

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 animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient. It is the second of three animations about cellular respiration.

This animation shows the reactions of the citric acid cycle, which splits off carbon atoms and generates energy-rich reduced forms of cofactor molecules. It is the first of three animations about cellular respiration.

This animation shows how the proton gradient across the mitochondrial membrane powers the ATP synthase enzyme to make ATP. It is the third of three animations about cellular respiration.

This three-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.

This interactive module explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest.

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.

This film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.
