Description

This video showcases the work of mathematician-turned-biologist Corina Tarnita, who uses quantitative approaches to understand the role of termite mounds in the savanna ecosystem.

Termite mounds are biological hotspots that concentrate nutrients and water in semiarid savanna ecosystems. When viewed from above, the mounds form a strikingly regular polka-dot pattern. Tarnita uses mathematical modeling to explain the regularity of this pattern, how it arises, and how the mounds enhance the stability of the ecosystem.

The accompanying “Student Worksheet” incorporates concepts and information from the video.
