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

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

This Click & Learn shows that keystone species exist across a variety of ecosystems and can exert their influence in different ways.

This video presents an intriguing phenomenon: two patients who carry the same genetic variation, which is known to cause sickle cell disease, have very different outcomes.

This video case study explores the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.

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 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 interactive module allows students to collect and analyze data from a virtual river to construct biomass and energy pyramids.

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

This interactive module explores how CRISPR-Cas9 technology works and the many ways in which scientists are using it in their research.

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

This video describes the case of a patient with retinitis pigmentosa (RP), a progressive disease that leads to blindness, and how physician-scientist Dr. Ed Stone approached the search for the causal mutation.
