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 short video explores how a baby’s microbiome is established during birth.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This video introduces the concept of niche partitioning with examples drawn from the African savanna.

This film tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.

This video describes the cutting-edge method of DNA metabarcoding and how it is used to study how animals partition resources in a shared habitat.

This video follows biologist Liz Hadly in Yellowstone National Park as she discusses how ecosystems are threatened by warming temperatures.

This animation shows how a region of the brain called the cerebral cortex develops in a human fetus.

This animation provides an overview of the greenhouse effect, a process that warms the atmosphere and surface of Earth.
