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 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.

In this video, ecologist Brian Silliman explains how he uses manipulative field experiments to study salt marsh ecosystems. His approach revealed that these systems are under top-down control from consumers and predators.

This video follows ecologist Mary Power, who is studying the Eel River in Northern California to decipher the connection between river flows and biodiversity.

This video follows the work of scientists conducting the first census of African savanna elephants in over 40 years and the methods they are using to obtain accurate, up-to-date numbers across the continent.

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

This video follows conservation biologist Leeanne Alonso as she surveys ant species in Gorongosa National Park to monitor the health of the park’s ecosystems.

This video follows scientists from Gorongosa National Park as they relocate zebras from a nearby reserve as part of the effort to restore healthy wildlife populations.

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.
