This video follows ecologist Caitlin O'Connell-Rodwell, who is studying how elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground.

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

This video follows scientists as they uncover the ways in which moth species in Gorongosa National Park use ultrasound to avoid being eaten by bats.

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

This animation shows how termite mounds can increase the productivity of African savanna ecosystems.

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.
