This video introduces the concept of niche partitioning with examples drawn from the African savanna.
Ecologist Robert Pringle explains the main ways in which large mammalian herbivores that coexist in the African savanna — including giraffes, zebras, and wildebeest — partition their habitat to reduce competition. He provides examples of herbivores partitioning their habitat by space (spatial niche partitioning) and diet (dietary niche partitioning), the latter of which may involve dividing food resources based on time or height.
